In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

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

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.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

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

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

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

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

Learners match puzzle pieces to outlines of a DNA strand. The puzzle pieces represent the four chemicals making up DNA base pairs: adenine, thymine, guanine, and cytosine.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

The goal of this Star Wars activity is to design and build a balancing device to help an Ewok escape the Imperial Forces by sliding down a tightrope to safety.

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
