Trading Places: Redox Reactions
Source Institutions
Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.
Toad Abode: Creating a Home for a Backyard Toad
Source Institutions
In this activity about backyard habitats learners create a safe and toad-friendly environment near their own home.
Forwards and Backwards: pH and Indicators
Source Institutions
Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).
Wild Sourdough
Source Institutions
In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.
Waterless Snow Globe
Source Institutions
In this activity, learners will investigate static electricity as they create waterless snow globes.
DIY Recycled Crayons
Source Institutions
In this activity, learners will experience the different states of matter using crayons as the medium. Explore matter changing between phases while recycling old crayons.
Scavenger Hunt
Source Institutions
An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv
Yeast Balloons
Source Institutions
Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.
Pollinator Play
Source Institutions
In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.
Make Your Own Ant Farm
Source Institutions
In this outdoor/indoor activity, learners collect ants and dirt to create an ant farm in a cup that they can observe over time.
Build a Fruit Fly Trap
Source Institutions
In this construction activity, students use a 2-liter bottle to build a fly trap.
Work Up An Appetite
Source Institutions
In this activity, learners participate in fun movement activities while playing on a giant game board. Use this activity to get learners involved in physical activity.
Good Vibrations
Source Institutions
This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.
Good Catch!
Source Institutions
In this activity, learners "go fishing," then practice ruler use and size/pattern comparison with the animals they catch.
Hot and Cold: Endothermic and Exothermic Reactions
Source Institutions
Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.
It's A Gas!
Source Institutions
Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.
All Mixed Up!: Separating Mixtures
Source Institutions
Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.
Building with Wonderful Junk
Source Institutions
In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.
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.
