Happy Friday in the Garden :
We are learning about Rain- Have fun with this easy STEM project to do with the kids....
- Cut the top section off a clear bottle as shown. ...
- Place several small rocks in the bottom (for weight), then fill the bottle with water to the 0 mark. ...
- Invert the top of the bottle into to rain gauge to act as a funnel. ...
- Wait for the next rain and obserCreate a log or a table to track rainfall in your area. For each entry, you’ll want to record the date, your rainfall measurement, and maybe even a sketch of the cloud cover that day. What other data might you want to record in your rain log?
Process:
Keep your eyes on the daily weather forecast, or look at the sky each morning. Do you expect a lot of rainfall today? Can you predict how much?
Re-calibrate your gauge each morning: empty out all of the water until it’s level with the zero-mark. If the weather has been very dry, you may have to ADD a small amount of water to get up to the zero-mark, to make up for evaporation that occurred overnight.
Take a measurement at the same time every evening, to see how much rain fell during the day. Make a note in your log of how many centimeters and how many inches of rain fell over the course of the day.
Take daily measurements for one week, two weeks, or one month. Do you see patterns emerging? Does your ability to predict daily rainfall based on cloud cover become more accurate over time? Why do you think that is?
