Ideas
How much water different fabrics can absorb, whether the colour of the fabric affects its temperature and how well different liquids stick to a particular fabric.
Investigate whether the viscosity of water is affected by the base area and depth it is contained within.
Most likely astronomical experimental idea
Build two telescopes (reflecting and refracting)which requires purchases of two convex lenses different in diameters and focal lengths.These will be used to visualise the sun while looking at the graph paper, so the sun wouldn't damage my eyes. This will test the accuracy of the telescopes to see which one is better at measuring the size of the sun. The time of viewing, place of viewing, approximate size of telescopes, experimental telescopes and measuring equipment will be kept the same. The independent variable would be the type of telescope and the dependent variable, the error in contrast to the stated size of the sun .

Alternate ideas....
I have looked up the internet and found many interesting experiment ideas including how permanent are permanent markers in different solvents and brands
, and whether the evaporation is affected by the amount and type of plastic wrap.
My own ideas are investigating the buoyancy of different types and sizes of balloons, and explaining how long it takes for different shapes and brands of soap to dissolve in water.
My preference is the solubility of different shapes and brands of soap. For this I would need at least four beakers filled up with the same amount of water. First, I would experiment with the shapes of soap keeping the brand,room temperature, time in water and shape of beaker the same. Next, I will experiment with different brands and keep the same controlled vraiables, except changing keeping of the same brand to keeping the same shape.The dependent variable would be the cm cubed of the soap dissolved and the independent variable, the shape of the soap. For my next experiment the dependent variable will remain the same but the independent variable will change to the brand of soap.
I can spend approximately 40 minutes per day, one day testing the experiment on the shapes of the soap, and another day testing the experiment on the brands of soap. This experiment will be repeated at least 5 times before the science report is due.
