# Do Maggots move towards or away from the stimulus of gravity?

Extracts from this document...

Introduction

Do Maggots move towards or away

from the stimulus of gravity?

## Prediction

I think that the maggots will move away from gravity. This is because it is an easier route for them to take.

## Method

We used:        Retort stand,

Boss,

Clamp,

Choice chamber,

Maggots,

Stop watch.

We are going to put twenty maggots into the choice chamber. Every thirty seconds we will count to see how many maggots there are

Conclusion

Evaluation

I thick that my work was quite accurate because we always tried to get the same equipment each week and did the experiment in the same place. So that the weren’t as many variables.

If I were to do this experiment again I would try to do all the tests on the same day so we used the same maggots and conditions for all the tests.

This student written piece of work is one of many that can be found in our GCSE T-Total section.
