Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.

In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity, young learners (2 years and up) explore dirt and what is in it by painting with mud.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this activity, learners will observe magnetic properties and sort objects by them. This activity uses everyday items to teach learners about magnetic forces, poles and properties of magnets.

In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.

In this craft activity, learners will explore the structure and purpose of antelope horns by constructing their own headband using toilet paper rolls and yarn.

In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.

Birds' beaks are designed to allow birds to get the most of whatever food they need. In this activity, learners get an idea of how different beak shapes suit different food sources.

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

In this activity learners will "rescue" animals from tape and then sort the animals. Learners will use science process skills such as categorizing and making observations while they play.

This is an activity about Newton's First Law of Motion - a body in motion tends to stay in motion, or a body at rest tends to stay at rest unless acted upon by an outside force.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.
