P4/5 have been learning about forces for science week. They have also been using science skills like how to test fairly. They tested to find out how the difference in force they applied had bigger and smaller impacts on what they were moving. They measured what they were doing in newtons and the testing was fair and accurate. They built rockets to test which would travel the furthest. They felt that the bigger force would have a better impact because it would make the rocket go further and faster.
They also did an experiment on how far a small car could travel. They had a chair and they had a elastic band. They put the elastic band round the chair legs and then one of them pulled the band back and then the other person put the car in front of the band and then the other person the band go and it shot the car forward. Then they marked down what distance the car had traveled. They then used smaller and bigger pulls on the elastic band to see if the distance would change. They learned how changing the size of a force could change the motion of what they were testing.
