Chemistry Labs

We’ve all done labs with our classes that originated with a legendary teacher from 1947 and exist only as a 17th generation photocopy.  For those of you who want to try something new, here are some labs that I’ve put together for your amazement and amusement.  As an added bonus, all of these have been edited for clarity and ease of use – if you’re still using the old versions, you may want to have another look!

Before you do your labs:

  • Student Safety Rules/Contract:  If you’re anything like me, you don’t want your students to die in your classroom.  To keep this from happening, how about some safety rules for them to follow?
  • Lab notebook guide:  If you’re going to do labs, you need a template that tells the kids how to do it.  Here’s that template for them, with a grading sheet for you, too!

Lab Manuals:

  • 24 Lessons That Rocked The World:  These 24 labs and activities are the foundation for my own chemistry classes.  Each lesson includes a lab, a handout, a practice sheet, a guide for running the lab, and answer keys.
  • 17 Effective Activities for New Chemistry Teachers:  Another 17 labs and activities that I use all the time with my students.  Generally the same format as 24 Lessons, but with a wider variety of stuff.

Miscellaneous introductory concepts:

  • Paper Airplane Lab:  A surprisingly versatile lab that can be used to teach the principles of the scientific method to everybody from remedial students to college students (information about how to do this is given).
  • The gum lab:  Which sweeteners are present in larger amounts?  This lab is nice for teaching about percent composition, or just for getting students comfortable in the lab. Several variants of this lab are discussed here.
  • Gold Penny Lab:  Fundamentally a scientific method lab, though it is also well-suited to teach about alloys.
  • Graphing lab – Cooking Spaghetti:  This is a very simple lab but provides excellent practice in data interpretation.  Suitable for all levels.

Properties of compounds:

  • Ionic Compound Lab:  Have your students determine whether or not a compound is ionic using its observable properties.  Teacher materials include variations for doing this lab with students with different skill levels.
  • Hydrate lab:  What’s the formula of Epsom salt?  Have your students find out in this inexpensive alternative to the hydrate labs we’ve known and loved.
  • Chemical and physical properties lab:  Is water wet?  Is salt soluble?  Well, this lab isn’t that easy, but it does teach about the chemical and physical properties of common chemical compounds.  (If you want a simpler, sillier, and quicker version of this lab, check out the chemical and physical properties activity.
  • Chemical and Physical Changes Lab:  Have your students figure out whether various laboratory exercises result in chemical or physical changes.  Depending on what processes you test, you can do this in just about any lab (even if it’s not very nice).
  • Make your own VSEPR activity:  Believe it or not, your students can figure out how VSEPR works on their own.  Check it out!
  • Intermolecular forces lab:  What’s the intermolecular force?  Have your students find out in real-time!

Moles and stoichiometry:

  • Moles of chalk lab (general chemistry)(honors chemistry):  How many moles of calcium carbonate does it take to write your name?  Find out here!  (Do you want to read this in Norwegian?  Click here.  Seriously.)
  • Stoichiometry Lab:  It’s safe, it’s fun, and it’s inexpensive.  Best of all, it’s fun to do!
  • Limiting Reagent Lab:  It’s simple.  It’s easy.  It’s fun.  What else could you want?

Reactions and synthesis:

Solutions chemistry (includes acids and bases):

Gas laws:

Thermodynamics and kinetics:

  • Heating Curve and Calorimetry Lab:  Let’s go for it!
  • Popcorn Kinetics Lab:  You’ll definitely want to wear goggles for this one!
  • Spontaneity Lab:  Our old friend thermodynamics strikes again!
  • Heat of Reaction Lab:  An explanation – though the purpose of this lab experiment is to find the heat of reaction of for the reaction of silver nitrate and lead chloride, the real lesson is that sometimes, despite your best efforts, good data are hard to find.

Real-world chemistry:

  • Silly Discovery labs:  For those of you who like to have a recurring fun activity in your class while maintaining educational rigor.
  • Alloy Computer Project:  Pretty much every metal we work with on a daily basis is an alloy.  Let’s teach our students about some of our wonderful alloy friends!
  • Defend your position:  If you’d like to see how your students attack a chemistry problem that’s a little more interesting than one you’ll find in your textbook, have a look.
  • Snow globe lab:  An art project that manages to celebrate the winter season while exploring solubility.
  • Oil spill lab:  We’ve had an accident and now there’s oil everywhere.  Can your students keep the environment clean and happy?
  • DNA Extraction Lab:  If your students have DNA inside of them, and I assume they do, they’ll be interested in seeing what it looks like.  The bad news:  It’s not DNA extracted from your students – it’s onion DNA.
