In this activity, learners build a carousel toy that spins when pushed down.

In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.

In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.

In this fun and imaginative writing assignment (page nine of the pdf), students will flex the creative side of their brains to learn more about the laws of motion and the scientific process.

In this activity (18th on the page), learners conduct an experiment to examine memory.

In this activity, learners perform an experiment that replicates the dilemma faced by birds in acquiring food from a confined area.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.
