Size and Scale
Discover Magazine recommends this activity in which students make a scale model of the solar system. The lesson plan also provides extension questions, evaluation suggestions and further recommendations for examining size and scale. This lesson is recommended for students in grades 9–12 but includes possibilities for including younger students.
Self-Assembly: Building Structures at the Nanoscale
Using simple materials – LEGOs, water and salt – students will gain an understanding of the challenges of building on the nanoscale level and tools that help scientists build on a minute scale. Recommended for middle and high school students.
Virtual Electron Microscope
This interactive sight allows students to "drag" slides to a virtual electron microscope, see the image and guess what it is. If students guess wrong, clues are given. This site would be great for high school students in advanced biology, but students in any grade might find the images interesting.
Perspectives: Powers of 10
Use this lesson plan to explore exponents and to teach the concept of scale. The "Secret Worlds: The Universe Within" Java tutorial zooms exponentially from 10 million light years away from the Milky Way to a quark. Recommended for middle and high school students.
"What order of magnitude is...?" Game
This game about magnitudes could be modified to work with almost any age group – from second grade to high school students – by changing the objects being discussed. For example, with elementary students, the discussion could involve the macro scale. With older students this activity could be used to discuss measuring distances in space or cell organelles.
Inquiry 3: How can I learn more about telescopes?
Use this guided inquiry lesson as a basis for numerous projects, from research about the Hubble telescope to hands on activities teaching about technology and working in outer space. These activities could be modified for any age group.
Tennis Ball Globes of the Moon
The Clementine Mission conducted remote observations in multiple wavelengths. Using the images of the Moon taken during Mission, students can create a globe of the Moon. This activity would be best for upper elementary and middle school students.
