It is a great fun maths activity which anyone can make. You only need a plastic bottle and a pair of scissors.
First cut the top about 1 / 4 of the way down.
Face the lid facing down into the bottle so the top is a wide brim so rain will easily fall into the bottle.
This rain gauge offers great maths, so now I can make tables of how much rain I will get in a week. Another thing I considered was how much wind we get at my house. The rain gauge would definitely blow away. So I shoved some rocks into the bottle to hold it down. To mesure the rain you will tip it into a mesuring cup. I cant wait until next week to measure my rain. Here's my work.
I am pleased you have decided to take on this maths challenge Sophia. I would suggest you create a table with the days of the week and record the rainfall daily. That way you will be able to work out the total for the week as well as the average (mean).
ReplyDeleteIt is neat to see you problem solve by considering the wind and adding weight to the bottom of the bottle.
I wonder if you and Charlie will record a similar rainfall as we live quite close to each other?
I look forward to comparing our table and graphs.
