Students are given a scenario for this lesson where they must use investigative skills like a detective would to decide whether changes that happen to objects in the story are physical or chemical. They then conduct an experiment with...

In this science fair project, use a globe and a heat lamp to investigate how the angle of the Sun affects global warming. This project includes the objective, background questions, a list of all the materials you'll need, and the...

Physicists sometimes study matter under extreme conditions. For example, think of the emptiness of interstellar space vs. the unimaginable crush of pressure at the center of a neutron star, or an object dipped in liquid nitrogen vs. the...

Some proteins are soluble in aqueous solutions and some are not. Insoluble proteins can be a problem because the proteins can form large aggregates in solution which are difficult to purify, crystallize, and use in experiments. Compare...

Learners will explore matter that sinks or floats when submerged in water and that matter is categorized as either a sinker or a floater. Students will work actively in small, cooperative learning groups as well as gather in a whole...

We've all had the experience: you're walking across a soft carpet, you reach for the doorknob and ZAP. But what causes this trademark jolt of static electricity? Anuradha Bhagwatsheds light on the phenomenon by examining the nature of...

Science experiment that demonstrates the four states or phases of matter: solid, liquid, gas, and plasma. Includes full list of materials, procedures, and scientific explanation of how you change water from a liquid state to a gaseous...
