Pre-Assessment/Invitation to Learn
Prepare and perform the following demonstration
The sock filled with the rice remains the same weight. As force (washers) is added to the paperclip, it reaches the point where the force is enough to move the weight. The greater the amount of force (number of washers), the greater the effect on the weight (sock); thus making the sock move across the tabletop and over the edge more quickly.
Tape the dowels together at each end.
Some balls are all the same size but they are not all the same weight. The weight of
each ball helps to determine how it will react when it collides with another ball. The materials
used to make each ball will also affect the experiment. Some materials absorb more
Science -What a Load! (ILO 1)
The force of the car remains the same. Additional weight is added to each run. At first, the amount of washers (weight) added does not affect the toys performance. Later on, each additional washer (increased weight) makes it more and more difficult to move the load. Finally, the load (weight/washers) cannot be moved by the amount of force applied.
