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

In this activity, learners keep track of how much paper the group uses in a week. Build awareness of paper waste, while strengthening measurement and estimation skills.

In this self-measuring activity, learners observe and record how many times a minute they blink, take a breath, and chew, as well as how many times a minute their heart beats.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

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 will construct a measuring device (snake "string") to improve their observation skills.

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 investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

Learners make kimchee or sauerkraut, which is really just fermented cabbage, in a 2-liter plastic bottle.

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).

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.
