Learners explore the endless possibilities of cardboard engineering in this open-ended STEAM activity. Practice being creative by building structures with no glue, only cardboard and scissors.

This hands-on activity shows you how to make a shaker -- a small instrument with a big sound! Fill it with beads or even pennies for a cool sound.

In this activity, learners play a matching game with their families to discover common inherited traits and traditions. Learners distinguish between inherited traits and learned traditions.

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.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

In this activity, learners play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

During this activity, learners take part in a variety of tasks which involve moving and balancing different body parts.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.

In this activity, learners write invisible messages on goldenrod paper, and make the message appear and disappear using acids and bases.

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.
