In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

Learners design their own experiment to investigate how pollution diffuses through ground material.

In this archaeology-related activity, learners build their own time capsule and choose a storage location and a date to reopen it.

In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

In this lab (Activity #1 on page), learners explore how we see color.

In this hands-on activity, learners investigate the functional design of leaves on a tree.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

In this activity, learners work in groups to create a time line representing significant moments in their lives.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

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

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

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

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.
