Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

In this activity, learners observe mixtures of sand samples glued to note cards, and consider how sand can differ in size, shape, and color, and where it comes from.

Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.

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.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

In this activity, learners will investigate static electricity as they create waterless snow globes.

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.

In this tabletop activity (on pages 32-40), learners make Möbius strips -- 3D surfaces with only one side.

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

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.

In this activity, learners grow germs collected from their hands and other objects. They cultivate the germs on a growth medium (such as slices of grapefruit or processed cheese) for a week.

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

In this activity, learners "go fishing," then practice ruler use and size/pattern comparison with the animals they catch.

This activity includes several games about animal sounds. Using their sense of hearing and communicating with various kinds of noisemakers, learners role-play predator and prey.

In this activity, learners use geometry in observing the shapes and angles soap bubbles create when they join together.
