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 activity, learners map their world by drawing a plan of their bedroom.

“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

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

In this activity, learners work in groups to create a time line representing significant moments in their lives.

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 create a model using metric measuring tapes and atmosphere composition data.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

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 explore how distance can affect the way we perceive the size of an object.
