In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

Learners design their own experiment to investigate how pollution diffuses through ground material.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners design a bungee jump for an egg using nylon stockings.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

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

In this activity, learners create a mixture of water, alcohol and permanent marker ink, and then add salt to form a colored alcohol layer on top of a colorless water layer.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

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 physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.

In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.
