In this activity (pages 8-9), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.

In this physics activity (page 5 of the PDF), learners will witness the effects of free fall by observing falling water, and will gain a better understanding of the concept of weightlessness.

In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

In this physics activity (page 3 of the PDF), learners will explore the concept of static electricity.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

This activity was designed for blind learners, but all types of learners can explore means of physically separating a mixture using dissolving, filtration, and evaporation.

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

Everybody loves boomerangs! In this activity about force and motion, the learners will experiment with boomerangs and explore how they work. This is a great activity to get learners up and moving.

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

In this chemistry activity, learners will test the pH of various foods and household substances using cabbage.

In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

En esta actividad, Mateo y Cientina descubren una sustancia nueva y extraña que se llama "Oobleck". En su experimento ven que Oobleck tiene propiedades de sólidos y líquidos.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this activity on page 7 of the PDF (Get Cooking With Chemistry), learners conduct an experiment to get an idea of how cheese is made.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.
