You are designing a race car powered by gravity. Type your list of materials and the cost here and explain how your design reduces friction.
Research how our ancestors told the time of day before there were watches and cell phones. Write a paragraph about this answering these questions:
- How did Attean (Sign of the Beaver) tell time? - Why are you able to use the Sun to tell time? - What were some of the materials used to make sundials? - Why was important to be able to tell the time of day? Go to one of these websites (or one your parents find) and make your own sundial. http://www.mysundial.ca/sdu/sdu_easy_make_sundials.html http://www.education.com/worksheet/article/make-your-own-sundial/ http://www.sundials.co.uk/projects.htm Take pictures or make a video of yourself making the sundial. Post the pictures/video to our class blog and write about the process. Include in your discussion: - Where you went online to find the instructions? - What materials did you use? - How did you use the materials to make the sundial? - What was the easiest part? - What was the most difficult part? - Would you want to have to use your sundial to tell the time? Why? Or, why not? |
