The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.
Free-Fall Bottles & Tubes
Source Institutions
In this physics activity, learners conduct two experiments to explore free-falling.
Message in a Neuron
Source Institutions
In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.
Effect of Environment on Plant Growth
Source Institutions
The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.
Forgotten Genius
Source Institutions
This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p
Musical Sculpting Machine: Squeeze Play-Doh to Make Music
Source Institutions
Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.
Fruit Xylophone: Fruit Salad Instrument of the Future!
Source Institutions
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.
Exploring the Ocean with Robots
Source Institutions
In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.
Corals and Chemistry
Source Institutions
In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin
Air, It's Really There
Source Institutions
This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.
Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.
Shake and Make: Charge Recognition
Source Institutions
In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.
History of Electricity
Source Institutions
This is a series of demonstrations about different electrical and magnetic phenomena.
Instant Ice Cream with a Dry Ice Bath
Source Institutions
In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.
The Carbon Cycle and its Role in Climate Change: Activity 2
Source Institutions
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
Cactus Needle Phonograph
Source Institutions
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.
How Do We Convert Mechanical Energy into Electrical Energy?
Source Institutions
In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.
Circuit Bending with Play-Doh
Source Institutions
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!
Bend That Bar
Learners play the role of materials engineers as they test the flexibility of different materials.
Rutherford's Enlarged: A Content-Embedded Activity to Teach about Nature of Science
Source Institutions
This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.
