Fizz Bizz
Bubbles seem to come from nowhere. Pupils investigate the formation of carbon dioxide bubbles in sodas. By placing different objects, including candies, in the soda, learners observe the formation of tiny bubbles on the surface of the...

Gas Sudsation
Bring out some bubbly! Individuals perform the classic baking soda and vinegar experiment with a twist. Learners add a drop of dish detergent to make the bubbles last longer. They vary the amount of baking soda and vinegar in an effort...

Introduction to Density
Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities:
Measurement of the mass and volume of fruit in order to compare densities
Measurement of the mass of oil and water...

Preparation and Combustion of Biodiesel
The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the...

The Energy Efficiency of Heating Water
Can a small change in laboratory procedures save energy? Scholars test three different methods for heating water in a science lab. Then, they calculate the energy efficiency for each and compare them to determine which uses the least...

Make Your Own Glue
You won't regret being stuck with this activity. By mixing a variety of household items, pupils create their own glue. They test the tensile strength of their glue and compare it to that of other adhesives.

Heart to Heart
Study heart health and math in one activity. After measuring their resting heart rates by finding the pulse in their wrists, learners build a stethoscope to listen to their heart rate, and note the differences between the two methods.
101 Questions
You Pour, I Choose
Tall and skinny or short and stout, which glass hold the most liquid? Learners analyze dimensions of cylindrical glasses to determine the one holding the greatest amount of liquid. They brainstorm the relevant dimensions before making...

Feed the Birds
What kinds of birds are common in the area? Young scientists use household supplies to create bird feeders. They then document the birds that come to their feeders by keeping journals.

Feed the Birds
Scholars use a large carton, string, an emery board, and bird food to create a hand-made bird feeder. After completing the craft, pupils keep a journal to track their observations.

How is Flowing Water an Energy Source? Activity C
Can the force of falling water through a tube vary by altering the diameter of the tube or its height? That is what physical scientists aim to discover in this activity, the third in successively more revealing activities on the power of...

Chem Collective: Cola and Sucrose Concentration Problem
In this activity, students use the virtual lab to prepare a sucrose solution for a soda recipe. They next calculate the concentration of their solution in terms of molarity, percent mass and density. Finally, they compare the density of...
