This lesson focuses on how materials behave differently as their surface area increases.

In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

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

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.

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.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

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

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

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

This Exploratorium activity explores size and scale. Through four levels of screen sizes, learners can sort out objects of different sizes.

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

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

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.
