In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

This activity is about collecting and analyzing DNA as part of a criminal investigation.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

This activity (page 3 of the PDF under SciGirls Activity: Dinosaurs) is a full inquiry investigation into fossil hunting and identification.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

In this activity, learners add squares to paper dominoes to make polyominoes.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.

This fun and simple activity is a rubberband rocket design challenge! Learners will explore how tail fins can help to stabilize a flying object, while also exploring potential and kinetic energy.

In this activity, learners will create a soil profile in a bottle. They will learn about the organic and inorganic matter found in soil and observe as it separates into layers in the bottle.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this craft activity, learners will recognize, name, and compare the fractions 1/2, 1/4, and 1/8 by constructing a penguin out of portions of paper circles.

In this activity (2nd activity on the page), learners explore the sensitivity of their sense of touch.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

In this activity (5th activity on the page), learners explore how what you see influences taste. In experiment 1, learners taste five sodas, one of which is clear soda with orange food coloring.

In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.
