This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Learners classify a variety of objects by their characteristics. They then design an experiment to determine which objects float or sink in water and add this characteristic to their classification.

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 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

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.

Learners observe the outside and inside of raw chicken eggs, record descriptions, and hypothesize what will happen when a facilitator drops an egg on the floor.

Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!

In this activity about the heart (on page 22 of the PDF), learners examine sheep or chicken hearts to learn about the heart's structure and the flow of blood through the heart.

In this activity, learners explore the properties of metals at four stations. The stations include A) Magnetism and Breakfast Cereal; B) Conductivity of Metals; C) Alloys; and D) Metal Plating.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
