Last Week in Science

Last week in Science we basically focused on motion. Our first tests were when we all chose a partner and faced each other. One time we pointed right and we pointed in opposite directions. The other time we pointed west and we pointed in the same direction. We also focused on positive and negative directions; on a number line right is positive and left is negative. Thus, we can make up positive and negative directions (other names for right and left basically). We also discussed the speed change. If a battery powered car is on and traveling, is it slowing down? Is it speeding up? or is it maintaining a constant speed? We devised an experiment where we ran the cars and marked where the car was after 1 or 2 seconds. Our hypothesis was that the car would maintain a constant speed. We will find out on Monday.
