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...

This in-depth organic chemistry lab walks learners through an investigation of the effect of initiator concentration on the resulting molecular weight of polystyrene. It is important that you use this lesson with experienced chemistry...

Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

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.

Compliment your physics lesson with this PowerPoint which demonstrates many important points regarding acceleration and velocity. A starter experiment activity to stimulate student thinking is given, and may prove very interesting to a...

How hard do you need to throw a ball in the air so that it never returns? Scientists call this measure the escape velocity. Classes can explore this concept through an intriguing interactive lesson. Pupils adjust velocities and observe...

Students calculate acceleration due to gravity with the measurements of the period of a pendulum or measurements of the time for an object to fall from different heights. They observe and measure the effect of air resistance on the...

What does stretching a balloon have to do with equilibrium? Groups explore preconditioning by stretching a balloon to a point of equilibrium. They then measure the amount of force required to stretch the balloon to the same point several...

Here's a resource with more bounce for the ounce! Engage your physical science class with an interesting interactive that allows individuals to perform tests with a mass attached to a spring. Participants can customize the scenario by...
