5. Thinking together….  SILENTLY each person should chose an object in the room…  SILENTLY think of how you could describe to another person how to get to that object from the classroom door….  With the person next to you, try to guess each others’ objects by giving your directions to that object (DON’T SAY THE OBJECT’S NAME!!!!)

8. Distance  DISTANCE is the measurement of two positions  In science, we measure distance in METERS  Kilometers for long distances  Centimeters for short distances

9. MOTION…  MOTION is the change of position over time.  Motion can be either: VERTICALHORIZONTAL

10. Speed   A measure of how fast something moves through a particular distance over a definite time period.   S=D/T

11. Speed Triangle

12. Speed Practice If a car travels 400m in 20 seconds how fast is it going? You must set up the speed triangle in order to do this!

13. Speed Practice   If you move 50 meters in 10 seconds, what is your speed?

14. Independent   On your own, complete the problems on the back of the lab sheet.   If you finish early, begin reading the lab sheet.   10 mins to complete
