Chemical Reactions Unit Of Measurement Alongside Interactive Notebook Pages

My physical scientific discipline students are almost done amongst our unit of measurement on chemic reactions, hence that way it's fourth dimension to percentage our interactive notebook pages.  

Each unit of measurement starts out amongst a unit of measurement divider.  You tin read to a greater extent than nearly these here.  

The other side of the divider features our SBG skills listing for the unit.  We had half dozen skills.  In retrospect, I should conduct hold taken the sixth science too turned it into an entire unit of measurement over the mole.  However, when I was reading the standards at the get-go of the year, I misunderstood just what was required inwards regards to the police of conservation of mass.  

Here's a close-up of the skills list.

We began yesteryear balancing chemic equations.  When I took chemical scientific discipline inwards high school, I ADORED balancing equations.  Each work was similar a mini-puzzle.  And, I beloved puzzles!

I set a circle inwards front end of each reactant too production to exhibit students where to write their coefficients.  Circles turned out to locomote a bad thought for this because some of my students mistook them for zeros.  I gauge I should role rectangles inwards the future.

After nosotros had the hang of balancing chemic equations, I had them interpret the equations from words to symbols too and hence residual them.

My students definitely appreciated the diatomic elements poster I made for them to reference!

We took a tiny intermission from balancing chemic equations to assort chemic equations.  I created this foldable to summarize the dissimilar types of reactions:

In the future, I would set synthesis too combustion on the foldable separately.  Having them on the same flap caused a lot of confusion for my students.

We also did some basic classifying reactions practice.

I created a carte form for my students to role to practise classifying reactions that I blogged nearly here.

After nosotros had learned nearly the dissimilar types of reactions, it meant nosotros were ready to acquire to predict the products of a reaction. 

I created a basketball game review game to review predicting products that I blogged nearly here.



The adjacent foldable nosotros created summarized the dissimilar types of systems nosotros would locomote dealing amongst inwards physical science.

I brought some props from domicile to assist us roll our heed some the dissimilar types of systems.  Well, the handbag of H2O ice was for some other experiment, but we'll acquire at that spot soon!

The cooking pot without the lid was an instance of an opened upwardly system.  The cooking pot amongst the lid on was an instance of a unopen system.  Both the thermos soup bowl too the H2O ice breast were examples of insulated systems.

To acquire my students thinking nearly the behave upon of temperature on reaction rate, I decided to do a demonstration amongst glow sticks.  It turned into i of the most enjoyable lessons of my didactics career!

Here's what my physical scientific discipline shape looked like:



The room was pitch dark thank you lot to dark out curtains from Tuesday Morning.  We didn't proceed the lights out all shape period, I promise.

I started our give-and-take yesteryear writing "glow sticks" on the board too bespeak students to tell me everything they knew nearly glow sticks.

My students were struggling to come upwardly up amongst things to percentage beyond obvious things similar "glow if you lot intermission them."  At this point, I passed out i glow stick to each student.  I was overnice too permit them alternative their color!

I bought a underground of glow sticks from Amazon for super cheap.  These (affiliate link) are the ones I bought.  Soon, students were intently studying their glow sticks.  I was SO excited when a educatee shared that they had heard that glow sticks final longer when you lot set them inwards the freezer.  We had a give-and-take of why this mightiness locomote possible.

Before long, i educatee accidentally bent their glow stick likewise much piece examining it, too it started to glow.  They were apologetic, but also super excited that they could come across the 2 liquids mixing too reacting.  I asked the other students if they wanted to intermission their glow sticks, too.  They did.

So, I turned off the lights, too my students sat at that spot breaking their glow sticks.  My students were SO engaged.  They were hence observant.  They were hence excited.  It was such a beautiful thing.  After a while, nosotros turned the lights on too planned an experiment.

We decided to seek out the behave upon of temperature on reaction charge per unit of measurement of glow sticks yesteryear placing glow sticks inwards 3 dissimilar temperatures of water.

We used a hot plate to oestrus H2O inwards i beaker.  And, nosotros placed H2O ice inwards some other beaker.  Our 3rd beaker was left at room temperature. I'm hence thankful for OERB for providing me amongst beakers, a hot plate, too a digital thermometer for my classroom.  I got all this too hence much to a greater extent than for gratis from attending i of their workshops.  

Here are our temperatures: 

I was originally disappointed that my beakers were non big plenty to fully submerge each glow stick.  But, that turned out to locomote a approbation inwards disguise.

Here were our results:

Because the glow sticks were non fully submerged, the business office of the glow stick that was non submerged acted the same equally a glow stick inwards room temperature water.  I was able to clit the glow sticks out of the beaker hence nosotros could come across merely how big of an consequence the H2O temperature was having.

My students were total of hence many ideas.  They enjoyed taking the glow sticks from i beaker to some other too predicting what would happen.  When the bell rang, they couldn't believe that scientific discipline shape had gone yesteryear that fast.  It was actually an awesome lesson!

I decided to follow upwardly our glow stick demonstration amongst an effervescent tablet lab.

This, sadly, did non choke that well.  I assumed that my students would locomote able to blueprint their ain experiments.  My groups tried to do this, but most groups didn't pay attending to what information they would demand to collect.  My students were putting effervescent tablets inwards the H2O without measuring the temperature of the H2O or measuring the starting mass.  It was chaos.  :(

I've since establish out that my students did non acquire to do many if whatever labs inwards their middle schoolhouse scientific discipline classes.  They merely haven't been taught how to gear upwardly an experiment to locomote successful.  Now I know too tin endeavour to locomote amongst them.

We had a few overflows that had to locomote cleaned up.  Thank you lot newspaper towels!

In the future, I volition give my students step-by-step directions for their foremost labs of the year.  We volition locomote towards designing our ain experiments toward the terminate of the year.

Another fault I holler upwardly I made amongst this lab was that I wanted them to alter both the H2O temperatures AND the organization type.  I holler upwardly I should conduct hold picked entirely i of these.

 I acquire hence frustrated amongst myself sometimes because I experience similar at that spot is merely hence much I do non know nearly didactics a scientific discipline class.  I'm learning every day, though.

For our adjacent experiment, nosotros made rust.  I thought that I had learned from my mistakes amongst the previous lab.  We spent a shape menstruation designing the lab together.  We wrote a hypothesis equally a class.  We discussed how to gear upwardly the experiment too collect data.

We used lather pads inwards lieu of plainly steel wool because that's what I could honour easily the dark earlier at Wal-mart.  Though, mayhap I should conduct hold looked inwards the domicile repair department for steel wool???

We soaked the lather pads inwards vinegar for some 5 minutes to take away some of the lather too the protective coating on the steel wool that keeps it from rusting inwards the box.

My students were convinced that the lather pads would entirely rust if nosotros left them inwards water.  The thought that they would rust inwards the air seemed to blow their minds.

Each grouping squeezed the vinegar out of their lather pads too set i inwards an opened upwardly organization too i inwards a unopen system.  They measured the starting volume of each system, too hence nosotros began our wait.

My students were convinced that nosotros would locomote waiting days too days earlier they started rusting.  I told them I didn't holler upwardly it would conduct hold that long.  Our physical scientific discipline shape is 2nd hour, too I conduct hold some of the same students inwards my fifth lx minutes Algebra 1 class.  It was to come across them excitedly banking concern fit their experiments when they came dorsum inwards my room.

Now, at that spot was an aspect of this experiment that I didn't quite holler upwardly through.  As the hateful solar daytime went on, my classroom started to odour to a greater extent than too to a greater extent than too to a greater extent than too to a greater extent than similar rust.  When students would walk inwards my room, they would at i time inquire what the odour was.  Rust!

After a day, our lather pads had choke sufficiently rusty to tape our observations too tape the ending masses.

This was where the experiment took a plow for the worse.  My students' measurements were ALL over the place.  One grouping had a starting volume of 50 or hence grams too an ending volume of nine grams.  They didn't seem to come across whatever work amongst this information that they had collected.

I wanted them to come across a clear correlation betwixt starting too ending masses too the type of system.  But, I'm afraid all they learned nearly was making rust.  :(  How do I acquire my students to conduct hold to a greater extent than accurate measurements???  We spent weeks at the get-go of the yr practicing using scales, hence I don't holler upwardly it's that they don't know how to role the scales.

The other affair I didn't conduct hold into consideration amongst this activity was that the rust would stain our containers.  When my students went to the bath sink (side consequence of didactics a scientific discipline shape without a scientific discipline lab) to endeavour too construct clean out the containers, they could non acquire the stains off.  I ended upwardly having to conduct hold them domicile too scrub them myself.

When my students wrote upwardly their lab reports, many did non fifty-fifty include the hypothesis that nosotros came upwardly amongst inwards shape together when nosotros discussed how nosotros would send out this lab.  My students beloved when nosotros do labs inwards class, but I conduct hold merely non establish an effective way to send them out yet.  If I terminate upwardly didactics some other scientific discipline shape adjacent year, I demand to do some SERIOUS thinking nearly how I do labs amongst my students.

When nosotros got dorsum from Christmas Break, I realized that nosotros yet hadn't done whatever labs to explore the consequence of concentration on reaction rates.  Frustrated from how our previous labs had gone, I decided to merely do a whole-class demonstration hence nosotros could motion on to the adjacent skill.

We worked together to do 3 dissimilar concentrations of H2O too vinegar inwards 3 graduated cylinders.  We measured the same amount of baking soda into 3 balloons that would locomote placed over the graduated cylinders to hit a unopen system.

Three students stood behind the graduated cylinders too lifted upwardly the balloons at the exact same fourth dimension to issue the baking soda into the vinegar/water mixtures.  Of course, nosotros made lots of predictions first.

Here's a video of our reactions taking place.  If the embedded video doesn't exhibit upwardly below, hither is a direct link to the video.  You tin take heed how excited my students were!

We did a quick notebook page to summarize what nosotros had learned nearly the effects of temperature too concentration on reaction rates from our experiments.

Up next: Molar Mass!

The text for this foldable came straight from this file.

My students conduct hold establish this grams/moles/particles stream nautical chart to locomote super helpful when nosotros are doing stoichiometry problems.

Converting Between Grams, Molecules, too Moles Practice:

We tested our novel establish skills yesteryear figuring out how many molecules nosotros would swallow if nosotros drank from the schoolhouse H2O springtime for xxx seconds. 

I had my students brand predictions earlier nosotros started.  Their predictions turned out to locomote waaaaaaaaaaaaaaaaayyyyyyyy off.  Let's merely nation the highest prediction was 1,000,000 molecules of water.  

Each grouping collected xxx seconds of H2O from the H2O fountain.  We measured the volume of H2O inwards each pitcher too averaged the results.  

It turns out the size of a molecule is super tiny too super difficult to roll our minds around!

There are yet 2 to a greater extent than pages for this unit of measurement that nosotros conduct hold non done yet, hence I volition locomote sharing them later.  They focus on the police of conservation of volume too limiting reactants.
