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?
