Writing for Night Vision
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl
Penny for Your Thoughts
Source Institutions
In this activity, learners will explore how metals react with each other. They will see these metals change before their eyes as they coat a paperclip with the copper taken from a penny.

Ramps 2: Ramp Builder
Source Institutions
In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

Make a Salt Volcano (Lava Lite)
Source Institutions
This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

Wind Tubes
Source Institutions
In this activity, learners create and experiment with wind tubes. These tubes are a playful and inventive way to explore the effect that moving air has on objects.
Shrinkers
Source Institutions
Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.
Concentrate: Concentrations and Reaction Rates
Source Institutions
Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

Breaking Point
Source Institutions
In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

Using Color to See How Liquids Combine
Source Institutions
Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.
Let's Go Ice Fishing
Source Institutions
In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

Super Shrinkers
Source Institutions
In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.

Mighty Seeds
Source Institutions
In this biology experiment, learners plant soybean seeds in plaster of Paris, witnessing firsthand the mighty power and ability of plants to grow in adverse conditions.

Spaghetti Strength
Source Institutions
In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.
Simple Submarine
Source Institutions
Using simple, inexpensive items, learners build and test submarine models.

Size, Scale and Models
Source Institutions
In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

Matter of Degree
Source Institutions
In two separate bags, learners mix water with Epsom salts and detergent.

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.

Dye Detective
Source Institutions
Learners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of water.

Raising the Level of Carbon Dioxide in Your Blood
Source Institutions
In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.
