In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

How can you make one shade of gray look like two? By putting it against two different color backgrounds! This activity allows learners to perform this sleight of hand very easily.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

Learners carefully look at four known household crystals.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

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

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

In this activity, learners discover that our hands are not reliable thermometers.

En esta actividad sobre la exploración e investigación, los aprendices harán ventanas de burbujas.

This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d
