Sand, Plants and Pants
Source Institutions
In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.
Sand Castle Saturation
Source Institutions
In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.
Sawing Away
Source Institutions
In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.
Egyptian Measuring
Source Institutions
In this activity, learners compare the ancient Egyptian system of measurement, which was based on body lengths, to the customary and metric systems used today.
Colors in Nature

In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.
Soda Geyser
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.
Out of Control
Source Institutions
In this outdoor activity, learners release a portion of a lawn from human control—no mowing, no watering, no weeding, no pest control—and then investigate the changes that result over several weeks.
Logs to Soil
Source Institutions
In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.
Monitoring Amphibians
Source Institutions
In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.
Witches' Potion Demonstration
Source Institutions
In this chemistry demonstration, learners will discover that phenolphthalein is an acid/base indicator. One learner will read a poem about four witches making a potion.
MarsBound!: Mission to the Red Planet
Source Institutions
MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.
In Search of Pollen
Source Institutions
In this activity (on pages 9-14), learners dissect a real flower -- the kind of work botanists do.
Making Babies
Source Institutions
This activity is designed to introduce learners to genes, genotypes and simple inheritance patterns.
Show Your Colors!
Source Institutions
In this family or group activity, learners conduct a chromatography experiment to reveal the colors that leaves "hide" under their green pigments.
Colored Shadows
Source Institutions
In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.
Otter Smorgasbord
Source Institutions
In this graphing activity (on pages 33-40), learners investigate how much and what kinds of food sea otter pups eat during their first year of life.
Downhill Race
Source Institutions
In this activity, learners explore how two cylinders that look the same may roll down a ramp at different rates.
Roller Ball Painting
Source Institutions
This is an activity in which learners explore the effects of gravity, motion and momentum while creating art.
Changing the Density of a Liquid: Heating and Cooling
Source Institutions
Learners investigate how the temperature of water affects its density.
Wire Maze
Source Institutions
Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.
