This activity is acid-base titration lab where students determine the percent of calcium carbonate in an eggshell.

The foamy fun of "Elephant's Toothpaste," also known as the catalytic decomposition of hydrogen peroxide, helped Camille Schrier win her job as Miss America 2020! In this episode, Camille re-creates this winning chemical reaction and teaches us all about the science of catalysts and decomposition. Explore questions such as: What is a catalyst? What does a catalyst do? Why do we need a catalyst to make "Elephant's Toothpaste"? It’s a HUGE, wonderful, foamy mess that's all powered by science! Developed for students in grades 6 - 10.

Learn about concentrations of solutions. If you brew tea or coffee for too long, it gets really strong, bitter, and dark. But if you add water, you can lessen its strength. So, when we talk about how strong our coffee is, we are really talking about CONCENTRATION. Like stirring a teaspoon of sugar into a cup of tea, solids can have a concentration in a liquid, but first, they need to be able to dissolve into a solution (solubility). But, is there a limit to how much of a solid the solution can take in? Through some sweet treats, you can eat, let's explore the scientific concepts of concentration, solubility, and supersaturated solutions. I promise you it's going to ROCK! Developed for students in grades 6-10.

This activity is a lab investigation where students collect and analyze data on towers built with various components and compare the two.

Here is a simple lab report that can be used in any science class (6-12). The report is designed to help students identify hypotheses, independent and dependent variables, controls, constants, and to analyze experiments. I have also included tips on a simple way to teach your students to identify the IV and DV through a "cave man hypothesis" and how to teach controls with less confusion.
