This activity is on page 3 (continued on page 2) of the pdf, part of the Simple Machines Discovery Box. In this fun activity, learners "create" a complex machine by simulating the parts in action.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

This is an activity about dinosaurs, fossils, and the work of paleontologists. Learners use hand tools (paint brushes, scoops, and sifters) to unearth fossil specimens in tubs of birdseed.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this activity, learners investigate different types of bird beaks using household items which mimic different beak examples.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

In this activity, learners are invited to imagine the park of their dreams!

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.

In this activity, learners use sieves with different-sized holes to sort balls by size.
