This activity is about the mural making process done about 9,000 years ago in Catalhoyuk, Turkey.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In this activity, learners make scale models of the Sun and Earth out of paper mache.

In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

In this fun snack and craft activity, young learners make "Ants on a Log" and their own model of an insect. The purpose is to learn the three main insect body parts—head, thorax and abdomen.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this math lesson, learners participate in a variety of activities that give them experience in recognizing, describing, and extending repeating and arithmetic patterns.

In this activity, learners draw natural objects to explore the details, differences, and similarities of natural objects.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this three-part math activity, learners explore shapes. In part one, learners identify, describe, and classify two-dimensional shapes.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

The Chinese invented paper made from plants and cloth about 2,000 years ago. Learners follow a similar process to make paper from recycled paper.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s
