Speed and Time Graph Practice

Journal Question 10 Oct 2012, P. 27 What is the average speed between points A and B? A B

Daily Double Journal Question 11 Oct 2012 Take an index card from the front table. On the front, answer this question: – Sally went to the mall with her mom. If they take short cut A, the mall is 5 km away and it takes them 20 minutes to get there. – If they take the longer route, the mall is 8 km away but it only takes them 16 minutes to get there. – Which route has the faster speed, A or B? Bonus: On back, – Convert your answers to meters per minute. – Convert your answers to km per hour.

Journal Question 15 Oct 2012 Please complete today’s journal questions on a separate piece of lined paper. You do not need to write out the question, but you do need to answer in complete sentences. 1.How do you think you are doing in science so far this year? Do you like science? 2.Is it easier or harder than you thought? 3.What can Dr. Schwach do to make science easier or more challenging for you?

Notebook Check All pages have a page number, bottom corner. Table of Contents up-to-date. Vocabulary complete. Journal questions listed and answered. Notes are legible and organized.
