You're Grounded
Source Institutions
In this engineering activity, learners test the stability of towers they build out of cups, discovering that structures with more mass in the base are more stable.
Fruit Juice Mystery
Source Institutions
In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.
Can Crushers
Source Institutions
In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.
Geometry Construction: Polyhedral Playthings
Source Institutions
In this activity, learners create 3D geometric shapes using straws and pipe cleaners.
Let's Make Molecules
Source Institutions
In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).
Size and Scale: Probing and Predicting
Source Institutions
In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?
Ice Cream
Source Institutions
In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.
Constellation Tubes
Source Institutions
In this activity, learners will create their very own constellation.
Lifting Lemon
Source Institutions
In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.
Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
Mars from Above: Viewing Volcanoes
Source Institutions
In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.
Make a Rainbow
Source Institutions
In this activity, learners will explore light and rainbows with this easy setup! Learners will only need a cup of water, some paper and a flashlight.
Counting Books: Make Your Own!
Source Institutions
On the first night, I saw 5 stars in the desert. On the second night, I saw 10… What do you think I saw on the third night? Combine arts and crafts, literacy, and math by making a counting book.
Partners in Pollination
Source Institutions
In this activity, learners identify the reproductive parts of plants and the animal (bee) structures involved in pollination.
Cylindrical Wing
Source Institutions
In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.
M&M's in Different Sugar Solutions
Source Institutions
In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.
The Shadow Knows I
Source Institutions
In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.
Milk Magic
Source Institutions
In this activity, learners experiment with how dish soap and fat interact by making a colorful swirl.
Drawing Conclusions
Source Institutions
In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.
Environmental Chemistry
Source Institutions
In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.
