Diatom Ooze: Ooze Clues
Source Institutions
In this activity, learners will plot the distribution of various oozes using information from sediment maps.
A Crayon Rock Cycle- Metamorphic
Source Institutions
This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.
Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
Fast Rusting
Source Institutions
In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.
Indicating Electrolysis
Source Institutions
In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.
The Ins and Outs of Tides: Learn About Causes and Predictions
Source Institutions
In this activity, learners will compare predicted and observed tides using data from The National Oceanic and Atmospheric Administration(NOAA).
Tsunami: Waves of Destruction
Source Institutions
In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.
Inverted Bottles
Source Institutions
In this activity, learners investigate convection by using food coloring and water of different temperatures.
Using Different Models of Earth
Source Institutions
In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.
Nuclear Fusion
Source Institutions
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
Telescopes as Time Machines
Source Institutions
This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.
Evolution in Action: Isolation and Speciation in the Lower Congo River
Source Institutions
In this guided discussion activity, learners watch a video about Central Africa's Lower Congo River, one of the most biologically diverse rivers in the world.
Sizing Up Temperature
Source Institutions
In this activity, learners explore Charles' Law in a syringe.
Supernova Star Maps
Source Institutions
This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.
A Crayon Rock Cycle - Igneous
Source Institutions
This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.
Simple Submarine
Source Institutions
Using simple, inexpensive items, learners build and test submarine models.
Building a Magic Carpet
Source Institutions
In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.
Home Water Audit
Source Institutions
This activity offers learners and their families several ways to raise their awareness together about home water.
Measure the Pressure II: The "Dry" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.
Make Your Own Barometer
Source Institutions
In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.
