What Is The Relationship Between Radon and Breathing?

Students investigate Newton's 2nd law using the Atwood machine. In this physics lesson, students analyze the relationship between forces and masses. They graph and analyze their results.

Determining whether or not something is living can be more difficult than it seems. Put your young scientists to work defining their own criteria to identify life, then work with three samples to see if they are alive or not. 

In this radon and radioactivity worksheet, students analyze the data of the isotopes of elements that occur in the decay series of uranium-238. Students answer 6 questions about the isotopes, their half-lives, their potential threat and...

What's the difference between a solar eclipse and a lunar eclipse? Handout an article that explains the phenomenon of both, safety precautions for viewing a solar eclipse, and what a partial eclipse is.

Enough talk about the Greenhouse Effect—let's actually look at it! Junior climatologists engage in a simple thermodynamics experiment on a cold winter's day to examine global warming. The activity simulates rising carbon dioxide levels...

How do you help your pupils understand the relationship between energy and forces? The video tackles standard PS3C using a concept map and demonstrations. The narrator also provides key vocabulary scholars should master at each grade level.

This year, an estimated 1,685,210 new cases of cancer will be diagnosed in the United States, and 595,690 people will die from the disease. Learners define cancer, see how and why it grows in the body, how doctors can treat it, and what...

Onions, garlic, and coffee can all have unfortunate effects on your breath, but what is the real cause of halitosis? Follow along with this video as it investigates how the bacteria that live in our mouths are responsible for these...

What is the difference between heat and temperature? By examining the properties of wood, metal, and plastic, high school chemists explore the concept of heat vs. temperature. Ensure that your high schoolers are following the procedure...

Teams learn about the size of a nanometer by measuring objects and converting those measurements. A worksheet then tests the groups' abilities to use nanometers by having them determine the size of objects that are too small to measure.
