Announcements  Gonzaga lost on Saturday to Wichita State.  It was a good game, but I didn’t expect GU to choke until the Sweet 16.  No quiz on Thursday so long as you are well behaved.  If not, there will be a full class test that will go on your third quarter grade.

Agenda  Vocab words  Speed  Speed Triangle practice  Bubble gum speed lab

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!!!!) (DON’T SAY THE OBJECT’S NAME!!!!)

 POSITION is the location of a place or object.  Often you describe where something is by comparing its position with that of something else  Can someone describe how they used this technique in the last exercise?

Reference Points  Each time you identify the position of an object, you are comparing the location of the object, you are comparing the location of the object with another location or place  The object or location to which you compare other objects or locations is called a locations is called a REFERENCE POINT.

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

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

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

Speed Triangle

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!

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

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

Bubble Gum lab   Please be respectful.
