Avi's Sensational Salt Dough
Source Institutions
In this activity on page 5 of the PDF, learners mimic the process for making bricks. Learners shape and bake creations from a dough that is made from flour, salt, and water.
Yeast-Air Balloons
Source Institutions
In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.
Tidepool in the Classroom
Source Institutions
In this activity (page 4 of the pdf), learners build a model of a tide pool, using chicken wire, paper mache, and other craft materials.
Energetic Musical Instruments
Source Institutions
Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.
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.
Oreo Phases
Source Institutions
In this activity, learners recreate the lunar phases using the frosting from Oreo® cookies and place the phases in order. Round cream cheese crackers can also be used if cookies are not an option.
Recycling Paper
Source Institutions
In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.
In Search of Pollen
Source Institutions
In this activity (on pages 9-14), learners dissect a real flower -- the kind of work botanists do.
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.
Life Story
Source Institutions
In this two-part activity, learners compare and contrast a variety of life cycles to better understand different organisms and how they develop.

Animal Reflection Response
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Horse Ears), learners observe how an animal responds to its own reflection.
Globby Gooey Gak
Source Institutions
In this activity, learners concoct some stretchy green goo called Gak. This activity will introduce learners to polymers, chemical reactions, and how scientists invent new materials.
Creating a Local Field Guide
Source Institutions
In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.
Soak It Up: Understanding Amphibian Permeability
Source Institutions
In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.
