Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

If you have a rotating office chair in your classroom, you can have physics pupils participate in this simple, yet effective demonstration of angular momentum. One partner sits in the chair, arms outstretched, holding heavy weights. The...

What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

In this human behavior science fair project, the student will learn about Piaget's developmental stages and the Theory of Conservation. The student will investigate the age at which children understand the equality of numbers and mass....

Students learn about material balances, a fundamental concept of chemical engineering. They use stoichiometry to predict the mass of carbon dioxide that escapes after reacting measured quantities of sodium bicarbonate with dilute acetic...
