Easy Weather Experiments to do in Your Garden: Rainfall

Weather Can Be Fun

Science is an important part of life and I like to do Fun Science with my children whenever I can. As the seasons change from summer to autumn it’s a good time to start looking at weather. There’s less sun, more wind and more rainfall to measure. These weather experiments are some of my favourite things to do in our garden and are easy to do even with a small amount of outside space.

Rainfall

We are equally cursed and blessed (name that 90’s band – one of my favourites!) to have a lot of rainfall in this country. Rainfall is one of the easiest things to measure in your garden and provides a good experiment to also practice some basic maths skills. We use a clean jug with easy to read increments along the side. I don’t recommend using anything too big because it will take ages to fill up. However, make sure you have a wide enough receptacle so the rain doest miss it! Put the jug outside and not under any shelter! On day one record the amount of rain in it (which should be zero). Every day get your children to record the amount of rain water in the jug. This experiment can get a bit boring if you have a few days with no rain.

If you want to be very technical you can make a proper rain gauge by cutting off the top of an empty plastic bottle. Using a measuring jug fill it with different amounts and draw a line to produce your own scale along the side. So, if you fill it with 10mL of water, record a line for 10mL. Repeat for 20mL, 30mL etc until. Since the bottle has a narrow opening to increase the chance of it catching rain use a funnel at the top.

Further Weather Experiments with Rainfall
  • When do you collect the most rainwater? During heavy or light rain?
  • Have you done this in different seasons?
  • What is the difference in rainfall at different times of year?
  • What was the most rainfall collected in one day? And what was the least?
  • How many days with no rain did you have?Fun science rainfall worksheet for easy weather experiments

We have started this experiment for the month of November. I’m sure my two will do an update post on what they’ve learnt. So far not much seeing as it’s been sunny! Not that I’m complaining about that. We’ll use paper and the iPad to record the results. They use both of those things in school. I expect my 8 year to manage this on his own, but my 5 year old will need some help.

Can you think of other weather experiments you would like to do?
