Hope you are keeping up with your weather diary. Has the weather changed much this week?
Make a rain guage. There’s an idea below of how to do it.
Each day you can check on your rain guage and record in your weather diary how much rain has fallen in the last day.
Remember this is a science experiment so have a go at predicting how much rain you will have in your bottle when you check it tomorrow.
Also, sometimes science experiments don’t quite work, if this happens ask yourself why hasn’t it worked. i.e. did the bottle fall over, is it in the wrong place to catch the rain.
