In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.

Use grape juice, baking soda, water and vinegar to make acid and base indicator paper! This activity contains a recipe and instructions for the indicator paper.

In this activity, learners discover how artists start with a skeleton and turn it into a realistic drawing of a dinosaur.

In this activity, learners will discover how to find the "sweet spots" on a baseball bat. Whenever an object is struck, it vibrates in response.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

In this activity, learners will explore how computers represent pictures using pixels.

In this math activity, learners sort patterns into similar "families" or groups that have the same pattern, but different symbols.

In this activity, pairs of learners model how scientists use craters to determine the ages of lunar surfaces. One partner keeps time while the other creates a painting for the other to interpret.

In this activity, learners will explore how the voice works and feel the vibrations produced by vocal cords.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

In this activity, young learners explore the basic shapes of constellations by making their own scope out of a cardboard tube and paper with pinpricks.

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

In this craft activity, learners will compare and contrast the major functions of plants and animals.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this hands-on activity, learners make New Year's Eve party hats out of wrapping paper. Learners use symmetry and measurement to cut out shapes they need to assemble the hats.

In this activity (located on page 2 of PDF), learners explore alternative uses of a simple paper cup, dubbed a "mystery item." Learners act as detectives and explore the properties and functions of th

In this Cyberchase activity, learners make carpenter's squares and use them to measure square corners. Learners cut out the carpenter's square template and attach it to tagboard.

This activity was designed for blind learners, but all types of learners can explore the process of extrusion used to produce pipes and wires in industry.

In this game, learners cutout a model black hole "cone" and attempt to roll around a marble or other small spherical object without touching the event horizon.

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.
