In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.

Learners investigate how the temperature of water affects its density.

Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.

In this activity, learners explore the great pump in their chests--the human heart!

In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
