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 .
