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.

Learners manipulate opaque, sealed boxes and attempt to determine their interior structures. Each box contains a moving ball and one or more fixed barriers.

In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.

In this math activity, learners estimate how many pennies are in a jar by predicting and counting handfuls of pennies.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this math activity, learners explore probability as they play a game. Learners will categorize everyday events as either impossible, possible or certain.

In this math lesson, learners explore probability.

In this activity, learners conduct scientific research on multitasking. Learners determine if multitasking with media while doing homework affects their ability to successfully complete the homework.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

In this activity, learners sample a star field to estimate the number of stars in the universe.

In this math activity, learners use a "function machine" to collect and organize simple data. The function machine in this case is a cardboard box and the input/output data are paper fish.

In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

Learners carefully look at four known household crystals.

In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.

In this lesson, learners are challenged to discover the relationship among six numbers.

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

In this math activity, learners predict how many pom-poms they can toss inside a circle from three feet away. Use this activity to help learners explore probability.
