In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this two-day activity (on pages 16-22), learners use a process like that of the Yoruba people of Nigeria to create an African symbol on cloth.

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

In this activity (page 19 of the PDF) learners will create a soda bottle bioreactor by exploring the science of composting, comparing variables such as reactor design, moisture content, and nutrient r

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this activity, learners explore how musical instruments are engineered.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this activity, learners will design a protective package for an egg that will allow the egg to withstand a fall without cracking.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.
