In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this activity about olfaction (7th activity on the page), learners use natural ingredients to concoct their own perfume.

This is an activity about reaction times. Just how quickly must an NHL goalie respond to save a shot, and how does your reaction time compare?

In this activity, learners investigate the basic crystal structures that metal atoms form.

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.

In this activity, learners explore how composites work by creating and testing their own composite for an imaginary company.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.

We don't normally view people upside down and so our brains aren't accustomed to it.

When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.
