We’ve had a lot of rain in the past few days – but how much rain have we had? We are going to make a rain gauge for you to measure how much rain you get in your backyard.
You will need: a clear plastic bottle (at least 1 litre capacity, water or soft drink bottle), scissors, masking tape, permanent texta, ruler or something else to use as a measure (lego, wooden blocks)
If you don’t have a clear round bottle, this is another version using a 2 litre milk bottle. I have used millilitres as a measure. I have tied it to my basketball ring so that it’s exposed to the rain.
Once you’ve collected some rain, you might like to record how much rain you get. Once a day, check your rain gauge. Once you can see how much rain is in it, make sure you empty it for the next time it rains. Write down how much rain you get each day – you might need an adult to help you. Or, if you’ve used lego or blocks, you might want to stack the lego or blocks for each day it rains (Monday – it rains 2 lego blocks, so you stack 2 lego blocks and keep them on a shelf. Tuesday – it rains 4 lego blocks, so you stack 4 lego blocks and put them next to Monday’s lego etc).
Making the rain gauge is a great STEM activity – it uses science, engineering, maths. It’s also great for fine motor skills.
It worked! Look at how much rain I collected.
