In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.

In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

In this activity, learners use a string and pair of scissors to find pi in the world all around them. Take the circumference of a round object with string and cut the string to that length.

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

In this activity, learners play a card game that explores different size scales--macro, micro and nano.

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

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

In this activity, learners "go fishing," then practice ruler use and size/pattern comparison with the animals they catch.

In this math activity, learners guess which cereals contain the most sugar. Learners use the nutrition labels on the cereal boxes to find the cereal with the least amount of sugar.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

Put math of measurement into lining up — and make waiting in line fun. Choose a size characteristic that learners can physically compare, such as foot length or hair length.

In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.

Spin a short piece of PVC pipe that's been marked up, and watch a triangle appear. Enjoy this optical illusion from the Exploratorium's Science Snack series.

In this activity, learners will make cleaning up more fun with predictions and counting. Estimate how many things are on the floor (or table), then count as they are picked up.
