You have to do a project in something that you like and enjoy. It does not have to be a very cool project, but a process that reflects the scientific method of any research. I will give you an example:

You want to measure how long the grass grows in a limited period of time, with different kind of nutrients in the water.

Your hypothesis might be that water with fertilizers makes the grass to grow faster.

Your experiment procedure will be to have different pots with grass and start watering them everyday, at the same time, with the same amount of liquid but different kids of water simple water, water with a kind of fertilizer, etc.

Then you have to measures the grass growth every day and start a chart with all your information. You do it for a month or any limited time that you choose.

At the end you report your results with pictures if possible, or only with the chart.

You also have to add some theory about your experiment that you find in a book from the library of on the Internet.

Remember: You do not have to do a complicated project, but you have to apply the scientific method that I mentioned above.

Think about something that you would like to do! You can also find out if salt affects the growth of flowers, for instance.
