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.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners identify different classes of matter based on physical properties.

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.

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.

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, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

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 activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

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

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.

In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

In this activity, learners will explore how metals react with each other. They will see these metals change before their eyes as they coat a paperclip with the copper taken from a penny.

In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

In this activity, learners create and experiment with wind tubes. These tubes are a playful and inventive way to explore the effect that moving air has on objects.

Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.
