The motion of objects can be observed and measured. 257 If you knew what to t u r n, If you knew what to t w i s t, If you knew what to push and pull And snap and click And crank and yank, Then this machine would probably do Whatever it is It’s suppposed to do. by James Stevenson Literature Poem ELA R 2.2.0. Students read and understand grade- level appropriate material. 258258258 *6A@j 7DJIjI What do you think this machine could do? 259 Position Lesson 1 How would you describe where something is? What words could you use? 2 PS 1.a. Students know the position of an object can be described by locating it in relation to another object or to the background. 260 ENGAGE Where is it? What to Do Work with a partner. Pick an object in the picture. Do not tell your partner what the object is. Communicate. Describe where your object is. Give clues to your partner. Your partner will find the object. Switch with your partner and try again. Explore More Communicate. Write directions to find an object in your classroom. Then switch with a partner. 2 IE 4.d. Write or draw descriptions of a sequence of steps, events, and observations. 261 EXPLORE Vocabulary position distance How can you describe where something is? Position is the place where something is. You can tell the position of an object by comparing it to something that does not move. You can use words such as above, below, left, right, near, far, next to, in, on, and under to describe position. What other words describe position? A The orange fish is to the left of the chest. 262 EXPLAIN When something moves, its position changes. You can describe its new position by comparing it to other objects. How do you tell the position of an object? A Where is the orange fish now? How did it move? 263 EXPLAIN Is it farther from Sacramento to Bishop or from Bishop to Los Angeles? How do you know? How do you measure distance? Look around you. What is close to you? Your desk is close to you. The board is near where you sit. What is far from you? The playground is far from where you sit. Washington, DC, is very far away from you. Distance is how far away one thing is from another. One way you can measure distance is by using a map.

Then you can write what you find out in a chart 266 EXTEND 2 IE 4.b Measure length, weight, temperature,... on a chart 1 How many inches was the longest jump? 2 How many paper clips was the shortest jump? 3 Write About It What else can you use to measure distance? 267 EXTEND Lesson 2 Motion How would you describe the motion of this roller coaster? 268 ENGAGE 2 PS 1.b Students know an object’s motion can be described by recording the change in position of the object over time How do different things move?... train The steam engine helped people travel over long distances It also helped them get to places faster 282 EXTEND ELA R 2.2.7 Interpret information from diagrams, charts, and graphs History of Science 1 961 Russian astronaut 1903 Yuri Gagarin was the first person in space Wilbur and Orville Wright His spaceship had built the first airplane that special engines that flew and landed safely Their were... run half a mile in 5 minutes An Olympic runner can run 1 mile in just 5 minutes or less! Speed is how far something moves in a certain amount of time 272 EXPLAIN Animal Animal Speeds 0 10 20 30 40 50 60 Miles per hour Read a Graph How fast would you have to go to beat a cheetah in a race? Which is the fastest animal? 1 Cause and Effect A girl is walking to school How can she get there faster? 2 How... If the finish line were farther away, would the same toy win? How could you check your answer? 275 EXTEND Lesson 3 Pushes and Pulls How can you make something move? How can you make it move farther? 2 76 EXPLAIN 2 PS 1.c Students know the way to change how something is moving is by giving it a push or pull The size of the change is related to the strength, or the amount of force, of the push or pull... Step Explore More Predict Try moving other objects Which object do you think will travel the farthest? Why do you think so? 2 IE 4.a Make predictions based on observed patterns and not random guessing 269 EXPLORE Vocabulary motion How can you tell if something has moved? speed Explore motion with the Treasure Hunters 270 EXPLAIN All around you, things move People walk up and down the street Leaves fall... It is harder to push or pull something on a rough surface than on a smooth surface A The thick treads on tires help cars drive over slippery roads The treads add friction between the car and the road 2 86 EXPLAIN A To slow down when you skate, you drag a rubber stopper on the ground The dragging causes friction Sometimes friction is helpful Running shoes have treads that add friction The shoes keep runners .
