This is a series of demonstrations about different electrical and magnetic phenomena.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

In this activity about potential and kinetic energy, learners get to roll a can across the floor and then watch it roll back to them as if by magic. This activity is always great for looks of wonder!

Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

The demonstration/experiment provides quick proof that air has mass.

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

A group of learners models the Sun shining on the Earth. By rotating the Earth, they demonstrate how the Sun only shines on a portion of the Earth at a time.

Learners will understand the relationship between climate change and sea-level rise.
