This activity teaches kids all about the science of the water cycle and can be easily completed at home!
You’ll need: a ziploc bag, a black Sharpie, blue food coloring, tape and a small measuring cup
- At the bottom of your ziploc bag, draw some ocean waves to represent water. At the top near the seal, draw a cloud in one corner and a sun in the other.
- Fill a small measuring cup with 1/4 cup of water.
- Squeeze four drops of food coloring into the water and then pour the blue water into the ziploc bag. Seal the bag tightly closed.
- Tape the bag to a window and watch the magic happen!
The Science Behind It:
Over the next few days as you watch the bag, kids will see the process of evaporation when the sunlight hits the water and turns into vapor. Next, condensation occurs as the vapor cools and turns back into liquid. After enough water condenses, it will fall in the form of precipitation.
