In this math lesson, learners apply the concepts of ratio and proportion to determine the length of the Statue of Liberty's torch-bearing arm.

In this math lesson, learners explore the concept of using units to measure length. Learners first read "How Big is a Foot" by Rolf Myller and learn about units.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

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

In this online activity, learners will explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

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 graphing exercise (page 2 of the pdf), learners compare their own height to the length of various sharks.

Did you know that using a lens one can bend light to make pictures of the world? It's true!

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 math lesson, learners explore the concept of using units to measure length.

In this math lesson, learners use inchworm measuring tools to measure the lengths of several objects in the room.

In this self-measuring activity, learners measure and record the length of their foot.

In this full inquiry activity (located on page 3 of the PDF under GPS: Kinetic Sculpture Challenge Activity), groups of learners will make predictions about which feature of a pendulum (mass, length,

In this math lesson, learners participate in several activities where they apply measurement skills.

In this math activity, challenge learners to make two equal rows from eight different paper strips. Learners can explore the many ways they can solve this problem.

In this activity, learners will decide together on a question about how far, long or high the group could reach together.

In this activity, learners will participate in a scavenger hunt involving sizes, shapes, and numbers. This activity works well with a whole group, individuals, or families.

This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.
