This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

In this activity, learners conduct a controlled experiment to examine how many Mentos are needed to make the tallest possible soda geyser.

In this activity, learners conduct a controlled experiment to examine which brand of soda makes the best (highest) soda geyser.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

In this outdoor activity, learners measure familiar objects in nature to practice working with the metric system.

In this matching activity (3rd activity on the page), learners use their sense of smell to match pairs of opaque containers filled with various smelly items like orange peel, roses, or moth balls.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

Get all wrapped up in a lesson about skin!

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this activity, learners compare ways to measure their heart rates. Learners build their own stethoscopes and learn how exercise affects heart rate.

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

Sound changes pitch relative to how you or the source of the sound is moving. Use this simple activity developed by the Exploratorium to experience the Doppler Effect yourself!

In this activity, learners will ask yes-no questions to identify a secret number (similar to Twenty Questions). Combine logic and numbers in this game for all ages.

In this activity, learners use geometry in observing the shapes and angles soap bubbles create when they join together.

In this activity, learners use their hands as tools for indirect measurement.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.
