Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

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).

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

In this activity, learners explore their eye pupils and how they change.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this activity, learners conduct a simple test to find their blind spot.

In this activity, learners control the (apparent) size of a hole with their brain.

In this activity, learners create a straw oboe to explore sound and pitch.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

Get all wrapped up in a lesson about skin!

In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.
