## How do you do a water cycle in a bag?

STEPS

2. Smooth the Ziploc® brand bag out on a flat surface.
3. Pour ⅓ cup of water into the bag (avoid filling the bag more than halfway).
4. Find a sunny window and tape the bag up.
5. Check in on the water cycle bag at different times throughout the next few days.

## How do you explain the project to the water cycle?

The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

What grade do you teach the water cycle?

This is a science lesson for students in grade three and four on the water cycle. Through this lesson students will be able to give an accurate and detailed description of the water cycle including the process that accompany it (evaporation, condensation, and precipitation).

### How do you explain the water cycle to grade 1?

Water Cycle Step #1: Water evaporates from the Earth’s surface. If you spill a glass of water outside you will notice that a few hours later the water is gone! That is because water slowly turns from a liquid into a gas called water vapor. The process of water turning from a liquid into a gas is called evaporation.

### What standard is the water cycle?

Standard 4.3.2.3 Water circulates through the Earth’s crust, oceans and atmosphere in what is known as the water cycle.

How to make a water cycle in a bag?

Directions. Draw a sun, cloud, and rain on your plastic baggie to represent the water cycle. Mix 3-4 drops of blue food coloring into the 2 cups of water. Pour the water into the bag. Holding the top of the bag in the air, use the Sharpie to make a wavy line across the top of the water to represent the lake/ocean.

#### How did I make a water cycle with food coloring?

I grabbed a Ziploc sandwich bag from our pantry and used a black Sharpie to draw a sun, cloud and water. Then, I filled a small measuring cup with 1/4 cup of water and pulled out our blue food coloring. Big Brother carefully unscrewed the lid to the food coloring and squeezed four big drops into the water.

#### Why does the water stay in the bag?

It’s because the water in the bag is being heated up against the sunny window. That water turns into a gas through the process called evaporation. In nature, evaporated water vapor goes into the atmosphere, but in our bag, it has nowhere to go, so it ends up sticking to the sides of the bag,…

What happens to water in the water cycle?

As that vapor cooled, it began changing back into liquid ( condensed) just like a cloud. And when enough water condensed, the air couldn’t hold it anymore and the water fell down in the form of precipitation.
