                      Key Learning:   Objects move as a result of force and motion.



                                                                 Unit Essential Question
                                                         How do force and motion affect objects?

      Forces in Action from the BBC has a number of activities to support see-saws, slides, swings. Gravity is the natural motion toward Earth-the
          students learning about concepts in the area of Force and Motion.    Earth pulls on objects.
      Whizzball is an online marble run to learn about changes in force
          and motion.
      Mrs. Coates 2nd Grade Force and Motion Activities has a number
          of experiments to conduct with worksheets to go with them.
      Force and Motion Experiments offer a variety of additional
          experiments broken down in as beginner, intermediate, and
          advanced levels.
     Magnet Forces Concept- Magnets can exert forces over long distances.
     Materials: Pencil with steal eraser holder, two donut magnets that fit
     onto the pencil. Procedures: Hold pencil so that it sticks to eraser
     holder. Drop the second magnet onto the pencil so that it repels the
     first magnet. Note that the falling magnet pops up when it reaches the
     bottom of the pencil.

     Assessment                    Make your own compass. Use a straightened paper clip, magnet, small piece of plastic foam, and a bowl of water.
                                    Rub magnet along paper clip in same direction. Place foam in water and lay straightened paper clip on the foam.
                                    Observe what happens and ask, Why did the paper clip point the way it did? (The clip has been magnetized so it’s
                                    pointing toward the north pole of Earth’s magnetic field.)
                                    Ask, how does it demonstrate push and pull?
                                   Make a ramp with books and roll a toy car down it. Measure and record how far it rolls.
                                    Repeat and make the ramp higher. Record results.
                                    Ask Why does the car roll a different distance each time?
                                    How does it demonstrate gravity?

                                        1. Individual Assessment
                                        2. Have 3 of the same textbooks, a ramp made from a piece of plastic or wood, to make a ramp, and science

                                       1. Give students a paper clip, magnet, small piece of plastic foam, and a bowl of water. Have them straighten the
                                          paper clip, rub it on the magnet and place it on the plastic foam. Then place foam in water and lay

                                          explaining in detail and thoroughly detailed drawings.

                                       2. Using their textbooks, and a matchbox car, place one textbook off the end of another textbook to make a

                                          ramp, one textbook high. Release car at top of textbook ramp and record how far it travels from the end of the
                                          ramp on the desk. For the second trial make the ramp two textbooks high and repeat releasing the car and
                                          record results. For the third trial, release car from four textbook high ramp and record results.

                                       2. These students can be the recorder for the group to ensure understanding and responsibility.

                                       1. Students carry out their own investigation about Force and Motion or Gravity, then record in a science journal
                                          to turn in.
       Advanced
