This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

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

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

Learners make their own simple slide rules out of paper and learn how they work.

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

Learners explore the endless possibilities of cardboard engineering in this open-ended STEAM activity. Practice being creative by building structures with no glue, only cardboard and scissors.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this activity, learners construct a home-made journal with simple, everyday materials.

In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

Learners work in groups to build model cars from paper parts. First, each learner builds cars individually and the group times themselves.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this activity (11th activity on the page), learners use pennies to test their hearing acuity.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.
