Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

Learners investigate a pre-constructed mystery tube to determine its interior mechanism.

In this interactive board game, learners "hire" different types of scientists to help canine character Ruff Ruffman solve unusual problems.

In this activity, learners explore the process of condensation.

Learners explore the physical properties of a variety of balls and how they bounce.
