Review: Measurement Directions: Copy and Answer the following questions. 1.What is another word that describes length? 2.The amount of space taken up by an object? 3.The amount of matter in an object? 4. A measure of how hot or cold an object is compared to a reference point? 5.The amount of matter per space an object take up?

Wordsplash Draw a line halving your paper. In the CENTER of the bottom half write the word MOTION in Big Letters.

Going to Grandmas House Investigation Task a. Create a trail from home to grandmas using colored drops. b. Measure distance and displacement using meter sticks. c. Chart and Record distance and displacement. Analysis Questions 1. How far was the school from home? ______ m 2.How far was the school from the store? _____ m 3.How far was is it from the store to grandma’s house? _______ m 4.What is the total distance of the trip? _______m 5.What is your displacement from your starting and ending point? ______m

Distance and Displacement Distance is the length of a path between two points. When an object moves in a straight line, the distance is the length of the line connecting the object’s starting and ending points. The SI unit for measuring distance is the meter (m). For very large distances, it is more common to make measurements in kilometers (km). For example, the Mississippi River is 3780 kilometers = 3, 780,000 meters. Displacement, on the other hand, measures a trip from the starting and ending point. For example if you take a trip from your home one way to the store and come back another way. Your displacement would not be the total distance of the trip. It would be the distance from your starting to ending point.

Scenario Directions: On a whole sheet of paper, draw the following route the boy takes from home to school using your ruler. Start your route two centimeters from the bottom on left side of the paper. One Block equals Five Centimeter (1 block=5cm). Use arrows to show the route. A boy starts walking from his home 1 block to the east. Then he turns a corner and walks 1 block north. He turns once again and walks 2 blocks east. For the last part of his trip, he walks 3 blocks north to school. Analysis Questions What is distance? What is displacement? What is the total distance of the trip in blocks? What is the total distance of the trip in centimeters? What is the total displacement? Draw a line on your diagram from the starting and ending point. Label the line DISPLACEMENT.

Frame of Reference How can you tell if something is moving fast or slow? You have to compare it to another object not moving. How can you tell if you are going in the right direction if you where lost at sea? Use the north-star. Using objects to gauge speed and direction is called frame of reference. Frame of reference is objects not moving with respect to another object. For example, the sun and moon are frame of references because they allow you to figure out your direction and speed. Other examples, a stop sign, a house, trees, not a bird. Suppose you want to know how fast people in a train are moving. You would use a frame of reference to gauge their relative motion. Relative motion is movement relative to a frame of reference. As the train moves past a stopped car, the people in the car would be able to guess the speed. Analysis Questions Directions: Copy the questions and Answer them. Use the passage to find your answers. What is frame of reference? Give two examples of a frame of reference. A leaf falls from the top of a tree and reaches the ground 4 seconds later. What would be the frame of reference, the tree or leaf? You are in space. A satellite is orbiting Earth. What is the frame of reference, the satellite or Earth?
