In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

In this activity (p.24 of PDF), learners make paper with fungi. Learners discover that paper is basically a flat mat of fibers.

In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.

In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).

In this chemistry activity (page 5 of the PDF), learners will use milk and a few other basic ingredients to create a chemical change to make a color wheel.

In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

In this chemistry activity (page 8 of the PDF), learners will identify the instances of physical change, chemical change, and solutions while making homemade soda pop.

In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.

This activity (on page 2 of the PDF SciGirls Activity: Milk Carton Boat) is a full inquiry investigation into boat hull design.

In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.

This lesson focuses on graphene and its electrical properties and applications.

In this experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

In this activity, learners use chemistry to produce weathered "antiqued" paper with burned edges. Learners first soak white paper in coffee and then apply a charring solution of ammonium chloride.
