5 Red Forces in Science.

Mrs Diaz

This terms unit for science is ‘Forces’ For our first lesson we looked at the gravity, resistance and identified balanced and unbalanced forces. The big question was ‘HOW DOES THE LENGTH OF AN ELASTIC BAND AFFECT THE DISTANCE IT STRETCHES?’ We had been invited to participate in the planning of rides for a theme park. This weeks focus was the Bungee Run ride. We investigated whether the length of an elastic band affects the distance it stretches. To prove this statement we used different size elastic bands and measured them using metre sticks. Take a look at the pictures below of us working on this theory.

WHAT DID YOU DISCOVER?

WOULD YOU HAVE CHANGED ANYTHING?

    I have discovered the more the pressure is the more the elastic stretches.
    The only thing I would change is that I would just see how would it be when it becomes shorter instead of longer.

    I discovered that the more force you put the more distance the elastic streches longer.
    I would change the amount of weight and the measurer as we could not see the measurements properly.

    We discovered that if you add pressure the measurement will go up.
    The weight objects didn’t really help to put weight on the tool that we used to see what the measurement were but it was worth it.
    I would have changed the weight to be heavier so we could easily get a measurement instead of 0.

    I would change about how many things in there

    I discovered that A rubber band provides the most energy when it’s stretched the farthest, and only a little bit of energy when it’s only slightly stretched. On the other hand the mass of the rubber band is added to the mass of the ‘projectile’, and both eat-up the energy.
