Science In a Van

We went to Science in the Van. The show was about the Troll and the Three Billy Goats Gruff. The Three Billy Goats Gruff wanted to cross the bridge but the Troll did not want to let them past. The goats got past by using forces like pushing and pulling and by using friction. We learnt that things do not move by themselves. Something does not move without a push or a pull. We also learnt that gravity pulls things to the ground and that we can create friction by rubbing our hands together.
