In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

In this multi-part activity learners examine non-point water pollution.

In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

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

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

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 activity, learners explore dinosaur fossils and a dig site. Learners work in groups to analyze a dig site map and match bones to a skeletal drawing of Kelsey (a Triceratops).

In this activity, learners investigate and compare the rate of drying in different conditions.

In this activity, learners will conduct an open-ended survey, and then organize and analyze results. What languages does everyone speak? What’s the most common? the least common?

This is an activity which will allow learners to gain an understanding of lemur behavior through observation and role play.

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

In this outdoor, night activity, learners track nocturnal animals' footprints, droppings and other signs of their presence.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).

In this activity, learners start their own field journal to better understand the wildlife in their area.

In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.
