In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

In this activity, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

Build a house you can fit inside, using cardboard tubes.

This is an activity about turbidity, or the amount of sediment suspended in water.

Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

In this activity, learners compare the ancient Egyptian system of measurement, which was based on body lengths, to the customary and metric systems used today.

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.

In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.

In this activity, learners make pretend snakes and use them to explore estimation and measurement. Learners roll out clay snakes and estimate and measure their lengths and diameters.

In this Cyberchase activity, have fun measuring volumes and enjoy a delicious shake.
