I can use data to explain understanding of the relative sizes and distances of objects in space.
Estimated Time for The Week: 1.5 hours, 90 minutes total
Engage:
- Ask yourself this question: How far away is the moon from the Earth? Try to imagine the distance using your experiences viewing the moon and your reasonable guesses.
- Watch the first 43 seconds of this video asking average strangers to estimate the distance between the moon and the Earth. Pause at 0:43 in the video before you move on!
- We are considering the phenomenon that human brains are not very good at estimating the size and distances of objects in the universe and working to get a better understanding of those concepts.
Explore:
- Make your own educated guess! Find a basketball and a tennis ball (or something roughly similar in size) and make your own educated guess on the distance between the Earth and the moon! Lay the objects representing the Earth and moon on the floor with the relative distance apart that you think they should have.
- Take a picture with your Chromebook and email it to another student telling them that this is your guess of the distance between the Earth and the moon.
- Continue the video now to find the answer.
- Open up a Google Doc. Title the doc “7th Science, May 11-13 [First and Last Name]”.
- On your new doc, add a copy of your picture of your Earth/moon model and answer the following questions (Hint: I am not necessarily looking for 100% correct answers, just looking for reasonable, educated guesses):
- How close were you in your estimate?
- What are some reasons why you think it is so difficult to estimate the distance between the Earth and the moon?
- If the Earth is represented by a basketball (about 9.5 inches), how many feet do you think an object would have to be to represent the sun on that scale?
- The distance in the correct scale model is about 24 feet between the tennis-ball-moon and basketball-Earth. How far do you think the basketball Earth would have to be from the scale-Sun in order to be accurate?
- When finished, you can share the google doc with your teacher if you would like. You can also check your answers on this sheet.
Learn & Explain: Use the content below to learn some key information & take notes as you learn:
- Read this article about the solar system and the objects within it.
- Answer the questions in the Review section near the bottom of the page.
- Watch the video almost at the bottom of the page so that you can answer the questions underneath it.
Elaborate: Use the resources below to go deeper and apply the learning to new levels.
- Visit NASA’s website detailing everything you could want to know about the solar system and its objects. You can use this website to explore specific questions or to get a good look at the solar system at this exact moment (try clicking on the orbiting planets icon to the left of the “solar system” tab near the top left). Spend at least 10 minutes exploring and learning on this website.
- Call or send an email to a friend telling them at least 3 things that you learned or found interesting from the NASA website. If you would like to send that email to your teacher, you could do that too.
Do & Connect:
- Complete the step-by-step Solar System Scroll activity as outlined here. Note that this is technically instructions on how a teacher could lead this activity but you can certainly just do it yourself! Don’t worry about if the paper that you can find isn’t just right; do the best with what you can find!
- Show someone your completed Solar System Scroll! This can be a parent or guardian, a friend, or your teacher if you choose! If you are really proud of it, hang it on your wall for a bit!
