Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

In this online interactive challenge, learners choose items to represent the Earth or solar system, then determine other items to represent the Moon, or Milky Way based on their relative size.

In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.

Learners compare a life-size drawing of a Tyrannosaurus rex head and a full-size Sinornithosaurus body to understand that dinosaurs varied in size.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

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

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

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.

“Exploring the Solar System: Big Sun, Small Moon” is a hands-on activity that explores the concept of apparent size and allows visitors to experience this phenomena using familiar objects—a tennis bal

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this activity, learners model the gravitational fields of planets on a flexible surface.

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.

In this activity (located on page 2 of PDF under GPS: Baby Dinosaurs Activity), learners will look for a relationship between skull size and body length among various dinosaurs.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners will investigate how craters are made and the different factors that contribute to size left from the impact.

In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.
