Observing+and+measurement


 * Background Research**

To come up with an appropriate research investigation about Tropism (Phototropism or Geotropism) you irst need to do some background resrearch and braistorming of ideas. There are a range of possible experiments that can be carried out. You need to ensure that you are testing a simple idea so that it can be investigated in a 3 week time frame. The Plant Hormone PowerPoint and Chapter 14 in Heinemann will give you some background information on plant hormones. The website [|Plants in motion]may also help you with background information and ideas. Some possible ideas for the experiment are
 * //• Investigate the phototropic response of wheat seedlings to light from one side.//
 * //• Investigate the phototropic response of wheat seedlings to blue light from one side.//
 * //• Investigate the phototropic response of wheat seedlings to red light from one side.//
 * //• Investigate whether the tip of a wheat seedling acts as the receptor to the stimulus of light.//
 * //• Demonstrate phototropic and geotropic responses in a germinating seed.//
 * //• Investigate the effect of ethylene released from a ripe banana on fruit or flowers.//
 * //• Investigate how seeds germinate when in light compared to being in complete darkness//
