What happens to puddles after the rain? Do this investigation to find out!
- Something to write on
- Something to write with
- Chalk (optional)
- A puddle!
- After it rains, find a nearby puddle to investigate.
- First, observe your puddle. Why do you think it formed here? What do you notice about the puddle?
- Then, make a prediction and record it on paper! What do you think will happen to the puddle in a couple of hours, a day, or two days? What makes you say that?
- Using a piece of chalk, mark the outside edge of your puddle.
- Come back every couple of hours and mark the edge again. Repeat this step a few times or until your puddle is dry!
- Finally, use your evidence to make a claim! What happened to the puddle? Why might it have happened? What else might you want to know? What else do you wonder?
- No chalk? No problem! Take a picture of your puddle instead and compare the pictures or record your observations by drawing a diagram of your puddle during each observation.
- Want to do it on a non-rainy day? Fill a cup of water and place it in the window. Mark the water level every few hours and use that evidence to make a claim!
