In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

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.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.

In this activity, learners will test the strength of different brands of paper towels.

In this outdoor activity, learners discover the wonders of the habitat surrounding them.

In this activity, learners will create a drawing with dry erase markers and watch it come to life. Learners will explore chemistry, art and storytelling through this activity.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this activity, children and adults work together to explore their relationship with technology and examine ways to make sustainable media consumption choices.

In this activity, learners explore ray optics. Learners discover that they can use a magnifying glass to create an upside-down image.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this "Sid the Science Kid" activity from Episode 108: My Ice Pops, learners observe reversible change while thinking about ways to make ice melt.

In this activity, learners will explore how and why weight distribution works.

In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.
