Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this physics activity about rotational inertia, learners use a spinning top made out of a bottle cap and a nail to explore how changing the axis of rotation affects how the energy is used.

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.

In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.

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.

Experiment with liquids of different densities and create liquid layers. For example, oil and water have different densities: oil floats on water because it is less dense than water.

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 Charles' Law in a syringe.

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.
