In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

In this activity, learners make self-assembled polymer spheres.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

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 activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

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