In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing

En esta actividad la tira cómica muestra a los participantes como pueden hacer un experimento simple para ver cuales líquidos son ácidos.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

In this physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs.

In this activity, learners explore the process of condensation.

In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.

This is an activity about friction as well as kinetic and potential energy.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.

These two activities (4th on the page) demonstrate the importance of two eyes in judging depth.

In this activity, learners grow germs collected from their hands and other objects. They cultivate the germs on a growth medium (such as slices of grapefruit or processed cheese) for a week.
