Five Years: Where has the fourth dimension gone?

When I graduated from college in addition to received my education certificate, I idea that a 5 twelvemonth certificate was a looooooooooooooooonnnnnnnnnnnnnnnnnnnngggggggggggggggg time.  Well, it turns out that 5 years tin larn yesteryear inwards a flash!  We withal accept i calendar month of schoolhouse left, but I simply submitted the paperwork to renew my certificate in addition to then it volition survive skillful until 2022.  Part of me thinks that that sounds in addition to then far away, but I know it volition likely wing yesteryear simply equally fast.

I spent quite a chip of fourth dimension final semester in addition to early on this semester studying for the chemical scientific discipline certification test.  I works life out nearly a calendar month agone that I passed!  This wasn't official until I filled out the paperwork today to add together it to my certificate.  I'm planning a weblog shipping presently to part my method for studying for the chemical scientific discipline certification test.  I wanted to expect in addition to brand certain I passed the examination earlier I shared!

Now it's official.  I'm certified yesteryear the pose down of Oklahoma to instruct math in addition to chemistry.


I wonder what the adjacent 5 years volition bring.  I know I never could accept dreamed of all the amazing things that accept happened during my start 5 years inwards the classroom.  Thanks to the #MTBoS for beingness at that spot for the entire ride!

Mole Poster - Avogadro's Number

One of the reasons I adore my physical scientific discipline bird is that they dear the posters I own got hanging upwardly inwards my classroom.  Decorating my classroom makes my view happy, in addition to the fact that I own got students who accept the fourth dimension to present appreciation for my difficult function only makes my view fifty-fifty happier.  A duet of weeks ago, my students insisted that I needed to brand a mole poster amongst Avogadro's number.  Of course, I'm pretty certain that 6.02 x 10^23 was stuck inwards their heads long earlier I got the poster on the wall because nosotros own got done SO MANY stoichiometry problems!  


The mole clipart is from www.supercoloring.com.

I printed this poster on 11" x 17" cardstock (affiliate link).  This materials is my go-to to making quick posters for my classroom!  It's the biggest newspaper size that my school's re-create machine handles.

Here's a duet of pictures of the poster hanging upwardly inwards my room.

Periodic Table of Mistakes Dry Erase Activity

Earlier this week, i of the scientific discipline teachers I follow on Twitter retweeted an activeness posted past times AACT.  The activeness was called The Periodic Table of Mistakes.  At outset glance, it looks similar a regular periodic table, but at that spot are truly 25 mistakes hidden within the table.    


I right clicked on the ikon in addition to selected "Open Image inward New Tab" in addition to thus I could zoom inward in addition to receive to spot the 25 mistakes embedded inward the periodic table.  Seeing Omg in addition to JK on the tabular array made me giggle, in addition to I knew that I had to detect a agency to role this activeness amongst my physical scientific discipline students.  My physical scientific discipline students did basic chemical scientific discipline outset semester in addition to basic physics 2d semester, in addition to thus it's been a spell since nosotros did anything amongst the periodic table.


Next calendar week is the final calendar week of the schoolhouse year, in addition to thus lately we've been simply doing a hodgepodge of activities since students receive got been gone for every possible result nether the sun.

 

I took the ikon in addition to placed it inward an eleven x 17 Publisher file that I exported every bit a PDF.  Then, I printed the file on simply about 11 x 17 carte du jour stocki (affiliate link).  This jumbo sized cardstock is a lifesaver inward the classroom.  I role it all the fourth dimension for reusable, group-sized activities inward conjunction amongst my 11 x 17 dry out erase pockets that I ordered from Amazon.


When my students came to class, I had them dissever into 5 groups since I had printed 5 periodic tables.  Each grouping was instructed to view a dry out erase marking in addition to a dry out erase bag amongst the periodic tabular array of mistakes inside.  I told each grouping that at that spot were 25 mistakes hidden inward this periodic tabular array in addition to it was their labor to detect them.


They began to eagerly search for their interactive notebooks that held their re-create of the periodic table.  When I informed them that at that spot were no references allowed, they moaned in addition to groaned.  They insisted that they wouldn't last able to detect whatever of the mistakes on their own.  I ignored their pleas in addition to instructed them to learn to work.


There were presently excited squeals in addition to giggles coming from the groups every bit they flora diverse mistakes.  I instructed them to circle each error every bit they flora them.  A prize was offered to the squad that identified the nigh mistakes correctly.


After 5 to x minutes, I had the students stop.  I used the answer telephone substitution provided past times AACT to become over each of the 25 mistakes.  They seat stars past times the mistakes they had identified correctly.  If I recollect correctly, the winning grouping flora eighteen of the 25 mistakes.


My students didn't intend that the mistakes that involved changing the atomic volume were real fair at all.  None of them noticed whatever of those.


This activeness tin last downloaded from AACT here.


Creating my Own Chemistry Certification Study Guide Using Qs from Other States

In a previous post, I promised that I would weblog nigh my method of studying for the chemical scientific discipline certification test.  Here are the details!   

This yr I taught my first-ever scientific discipline class.  Now, I never planned on beingness a scientific discipline teacher, then I never took whatever steps toward beingness certified to learn science.  This year, I was able to learn i catamenia of scientific discipline without certification equally a "co-teacher."  This meant I taught the shape on my own, only I nether the guidance of i of the certified scientific discipline teachers inwards the building.

I decided to seek out my ain scientific discipline certification past times passing the OSAT (Oklahoma Subject Area Test) inwards Chemistry.  On President's Day, my hubby together with I drove to Stillwater then I could accept my exam.  It was a long hold off until March when I finally flora out that I PASSED!


I do receive got some chemical scientific discipline inwards my background.  As a high schoolhouse sophomore, I took a Pre-AP Chemistry class.  Then, equally a high schoolhouse senior, I took AP Chemistry.  I did genuinely good inwards the class, together with I ended upwards scoring a v on my AP test.  This v netted me college credit for Chem I together with Chem II from The University of Tulsa.  I notwithstanding needed a lab credit inwards scientific discipline to graduate, then I took the Chem I lab shape equally a college sophomore.  And, that was the lastly fourth dimension I did whatever chemistry.

For the get-go iv years I worked at Drumright, our chemical scientific discipline computer programme was super-small.  The shape would ever attain from 3-5 or then students, together with pupil morale was to a greater extent than oft than non low.  I would oft abide by myself helping students amongst their chemical scientific discipline assignments.  They would inquire me why I didn't learn chemical scientific discipline since I explained it then well.  I ever told them that I would dear a jeopardy to proceed chemical scientific discipline i day, only I wasn't certain if I would live able to exceed the certification test.

Fast forrad to this year.  Our upper-level scientific discipline instructor retired, together with the seat was non rehired due to budget cuts.  A few days earlier schoolhouse started, I was given the alternative betwixt adding a quaternary prep of Algebra 2 or Physical Science.  I had worked genuinely difficult to non receive got to learn Algebra 2 this year, then I chose to learn physical science.  I rapidly flora out that I LOVED the chemical scientific discipline business office of physical scientific discipline together with didn't dear the physics department of physical science.  This is what convinced me that I needed to earn my chemical scientific discipline certification.

I knew I would require to written report Influenza A virus subtype H5N1 LOT since it had been over ix years since I had genuinely sat inwards a chemical scientific discipline class.  I started my studying past times visiting the website for our set down certification tests.  The website offered me a whopping 10 sample multiple alternative questions together with 1 sample constructed response question.  Given that I had problem answering quite a few of these sample questions, I knew I would require then much to a greater extent than practise than these eleven questions provided.

Influenza A virus subtype H5N1 quick google search showed me that at that spot were a few essay prep books on the marketplace seat (affiliate links).

   


But, afterward looking at their steep toll tags, I decided to do my ain written report guide.

I began past times creating a divider for each subarea of the test.



Next, I created a subdivider for each competency.


These were hole punched together with placed inwards a binder.  I printed off each of the sample questions offered past times Oklahoma's CEOE together with placed it behind the appropriate competency.  I printed them double-sided then that the enquiry was on the forepart of each page together with the reply was on the dorsum of each page inwards pocket-sized print.

Then, I went on a mission to abide by equally many practise problems equally possible.  I combed through each state's scientific discipline certification tests together with picked out every unmarried chemical scientific discipline question.

I harvested questions from California, Florida, Illionis, Indiana, Minnesota, Missouri, New Mexico, New York, Ohio, Oklahoma, Michigan, Oregon, Washington, together with the Praxis.

This ended upwards beingness a bunch of questions.  Of course, that's just what I was hoping for!

I printed these questions the same agency I did the Oklahoma questions.  One enquiry per page.  Question printed on the front.  Answer printed on the back.

Here's an representative of a enquiry page:



The snipping tool was my best friend that made this projection feasible.

It was a chip tricky sorting the questions from each dissimilar set down to correlate amongst the Oklahoma competencies, only I shout out upwards this added to the learning sense because it meant I had to do a lot of inquiry nigh what some of the questions fifty-fifty meant.

Here's my finished written report guide:




By the fourth dimension I got all of the pages inwards my binder, it would barely close.  I worked through each problem.  Many of the problems I had to skip together with come upwards dorsum to.  Some became clear afterward working through other related problems.  Plenty of others had to live googled.  My husband had to assist me empathise the dissimilar types of nuclear decay.

This binder ended upwards traveling amongst me everywhere.  It made the trek to schoolhouse each solar daytime then it could swallow tiffin amongst me.  Many weekend afternoons were spent curled upwards amongst this binder, a highlighter, together with my laptop.  I receive got to acquire to church building early Sundays because my hubby is inwards the band, then I would sit down on the couch inwards the antechamber of the church building together with written report chemistry.

It ended upwards beingness worth it because I passed!

I've decided to upload the files I created for this written report guide here inwards instance it powerfulness live of role to somebody else.  I'll warn you lot that these files are non perfect.  One of the state's questions copied together with pasted a chip weirdly.  Another file has 2 of the answers switched roughly accidentally.  But, I know that fixing a few pocket-sized mistakes won't accept close equally long equally it took me to do the master copy files!

Next, my conception is to do the same affair for physics then I tin forcefulness out learn myself!

Must-Have Supplies for a New Physical Science Teacher (Part 1)

Well, I've officially finished my kickoff twelvemonth every bit a physical scientific discipline teacher.  It wasn't a journeying I planned on taking, but I learned in addition to therefore much from the experience.  For example, I re-learned simply how much I dearest chemical scientific discipline in addition to don't dearest physics.  I gauge that's the argue I sought out my chemistry certification in addition to therefore I volition hopefully live able to learn 2 periods of chemical scientific discipline a twenty-four hr menstruation adjacent year.  Don't worry, math volition ever live my kickoff love!  

This is the kickoff one-half of a mini-series close the supplies that I considered a must-have inwards my physical scientific discipline classroom.  Now, you'll direct hold to maintain inwards heed that I was teaching scientific discipline inwards a regular, non-lab classroom.  This led to having to brand numerous, numerous adaptations that would non live necessary inwards a laboratory setting.  Hopefully this post service volition assist inspire a hereafter physical scientific discipline teacher!  

Please banknote that this post service does contain affiliate links.  If y'all purchase whatever of the items featured, I volition have a pocket-size constituent of your purchase price.  This costs y'all cypher at all, in addition to it helps pay for the file hosting on this blog.  



Cupsve.  My students ofttimes needed a fleck of H2O for a lab activity.  Since I don't direct hold a sink inwards my room, I would direct hold to send them to the bath sink to fetch water.  These cups saved the twenty-four hr menstruation for this many times before I was able to have some proper pitchersve through a local grant.


Rube Goldberg machines.  I latterly ran across a scatter plot activity involving fourth dimension vs. pose out of dominoes that I would dearest to comprise into my Algebra 1 cast adjacent year.  Looks similar I demand to acquire a few sets of my ain dominoes for my classroom!  



HS Science Workshop amongst OERB.  Then, I received half-dozen to a greater extent than local donor.  I know that my students could ever work their prison theatre cellular telephone phones every bit a timer, but I would rather my students NOT direct hold their phones out during a lab!  These travel perfectly, in addition to my students dearest using them.  



Baking Sodave.  Not having a proper scientific discipline lab has meant that I had to live really creative amongst the types of chemicals nosotros were able to work during labs.  Baking soda made a few appearances inwards our curriculum!  


Saltve.  This was some other mutual solid exceptional that my students were able to work inwards their labs without having to worry close disposing of toxic chemicals.  


Effervescent Tabletsve.  My students completed a lab where they compared the comport on of dissimilar H2O temperatures on reaction rate.  Effervescent tablets worked perfectly for this.  


Packing Peanutsve.  I originally saved these thinking that my students could work them for some form of density activity, but they genuinely came inwards most useful for our egg drib project!  


Do Not Remove This Card. I created these laminated cards that read "Do non withdraw this card" afterward seeing Steve Spangler produce the same at a workshop amongst his Mysterious Water Suspension trick.  I direct hold some awesome video I took inwards cast when doing this activity that I demand to portion soon!    




OERB Workshop.  I dearest that they are plastic in addition to therefore I don't direct hold to worry close cleaning upwardly broken drinking glass if they acquire dropped.  We used these to explore measuring volume, in addition to nosotros continued using them inwards lab afterward lab.  My Algebra 1 students fifty-fifty got to work them for our Crow in addition to the Pitcher activity.  


Mini Metric Olympics.  They're also simply to a greater extent than ofttimes than non useful for cleaning upwardly afterward labs!  


OERB workshop.  Most of my labware is plastic due to existence inwards a classroom setting instead of a laboratory setting, but it was overnice having some glassware that could live placed on our hotplates.  


Digital Thermometerve.  We did several labs that required testing the comport on of dissimilar temperatures of water.  Having a digital thermometer made our information collection in addition to therefore much easier!  Now, I demand to honour a agency to acquire my hands on a cast laid of these! 


Mini Metric Olympics.  We also used them when practicing measuring volume.  My Algebra 1 students used them for our Crow in addition to the Pitcher activity.  I'm also thinking they would live keen for modeling electrons on Bohr models inwards the future!          


lab on making rust, y'all purchase these.  In the future, I'll honour somewhere to purchase some proper steel wool for that lab!  


Mrs. Stewart's Liquid Bluingve.  We used this to brand crystal "Chemistrees" correct before Christmas Break.  Yet some other activity I yet demand to weblog about!




Flaskve.  Remember my tiny, 100 mL glass beakersve from earlier?  For quite a while, these were the exclusively glassware inwards my classroom.  Heating a substantial total of H2O on the hotplate amongst exclusively 100 mL beakers takes a LONG time.  Eventually, I broke downward in addition to borrowed a 500 mL flask from the one-time HS chemical scientific discipline lab.  This made heating H2O in addition to therefore much to a greater extent than efficient.  


Oven Mittsve.  These were a gift from my hush-hush pal.  I'm certain she meant for them to live used inwards my kitchen, but they worked perfectly for removing glassware from the hotplate!  


OERB workshop.  We didn't produce much amongst organic compounds inwards Physical Science, but I did learn my students to name in addition to model the diverse alkanes.  They had a lot of fun edifice the dissimilar models!    


Platform Scaleve.  My mom picked upwardly this scale for me at a yard sale, in addition to it worked perfectly for when nosotros needed to honour the volume of items that were likewise large for our triple beam balances.  


Plastic Containersve.  These were perfect for carrying H2O in addition to containing experiments.  My students were in addition to therefore amazed that they nested ane within of another.  If y'all accept them out, they maintain getting smaller in addition to smaller in addition to smaller in addition to smaller!    




TI-30XS Calculatorsve.  I LOVE these calculators for both my Algebra 1 classes in addition to my Physical Science class!  They are the most user friendly scientific reckoner I direct hold came across!  


Triple Beam Balancesve.  I was able to borrow a laid of these from our one-time HS chemical scientific discipline lab, in addition to I am in addition to therefore glad I did.  It was quite a patch before I was able to acquire my hands on a digital scale, in addition to therefore this was all nosotros had for measuring.  I had many of my physical scientific discipline students inwards Algebra 1 every bit well, in addition to those kids loved showing off their measuring skills inwards math class!  


Vegetable Oilve.  This was some other ane of those mutual solid items that showed upwardly inwards classroom activities.  


Pitchers.  Remember when I was having to tote H2O from the bath inwards plastic cups?  These pitchers from EAI Education made transporting H2O to the classroom SO much easier.  The pour spouts kept my room a lot drier in addition to cleaner, too!  


Plastic Test Tubes amongst Racksve.  These are marketed towards main students, but I dearest existence able to work them amongst my high schoolhouse students because I don't direct hold to worry close drinking glass breaking.  It does hateful we're express every bit to what chemicals nosotros tin forcefulness out pose inwards them, but every bit y'all tin forcefulness out tell already I kept the chemic listing pretty tame this year. ;)  


Measuring Cupsve.  These got most of their work measuring out baking soda in addition to common salt for diverse labs.  


Graduated Cylindersve.  I was lucky to acquire grant coin from our local pedagogy foundation to purchase to a greater extent than plastic graduated cylinders for our diverse labs.  


Plastic Beakersve.  These plastic beakers are also from EAI Education in addition to were also purchased amongst grant coin from our local pedagogy foundation.  


Digital Scaleve.  I'm non certain what to nation close this scale.  My students definitely prefer it to the triple beam balances, but they broke it on the kickoff work out of the box.  :(  It yet works, but the overstep doesn't remain attached similar it should.  


here.  


Mason Jarsve.  These were used for Steve Spangler's Mysterious Water Suspension Demonstration.  If I don't weblog close this soon, delight remind me!  


Bubble Wrapve.  This protected many an egg inwards our egg drib competition!  


Two Liter Bottles.  These were used for experimenting amongst inertia inwards the hex nut probability lab.  We also used them inwards a lab I haven't blogged close yet where nosotros examined the most efficient agency to empty a two-liter bottle.    


Ammoniave.  This was an of import element inwards growing our "Chemistrees."


Vinegarve.  If baking soda is inwards your lab, y'all improve direct hold vinegar, too!  


Dry Erase Pocketsve.  I used these to brand many of our physical scientific discipline activities interactive in addition to reusable.  My students dearest using these pockets!  


Slotted Weightsve.  These were perfect to add together to diverse objects to vary the weight during a lab.  


Marble Roller Coasters without marbles!  These would also travel for the Mini Metric Olympics in addition to the Crow in addition to the Pitcher activity.    


Scientifico.  They would also travel keen for modeling electrons inwards Bohr diagrams.  


Meter Sticksve.  These are likely the most used exceptional inwards my scientific discipline class.  We used them for EVERYTHING.  


here




here.  


Magnets.  My sis gave me these circular magnets, in addition to they were perfect for modeling how to describe Bohr Diagrams on the dry out erase board!  


Paper Platesve in addition to Circle Stickersve.  While I modeled my Bohr Diagrams amongst magnets, my students created their models using paper platesve in addition to circle stickersve.  


This represents exclusively role of my listing of must-have supplies, but I demand fourth dimension to accept to a greater extent than photos before writing upwardly the minute half!
