Creating a water cycle model using a clear jar, water, and food coloring

Objectives:

• Students will be able to explain the different processes involved in the water cycle.
• Students will be able to identify the different stages of the water cycle.
• Students will be able to create a water cycle model using a clear jar, water, and food coloring.

Materials:

• Clear jar
• Water
• Food coloring
• Permanent marker
• Tape
• String
• Scissors

Procedure:

1. Gather the materials.
2. Wash the jar and dry it thoroughly.
3. Use the permanent marker to draw a cloud on the top of the jar.
4. Fill the jar with water until it is about halfway full.
5. Add a few drops of food coloring to the water.
6. Tie a piece of string to the top of the jar and hang it in a sunny spot.

Observations:

• Over time, the water in the jar will evaporate.
• The water vapor will rise into the air and form clouds.
• The clouds will eventually condense and form precipitation, such as rain or snow.
• The precipitation will fall back to Earth, where it will collect in rivers, lakes, and oceans.
• The water will then cycle back to the beginning of the process.

Assessment:

• Ask students to explain the different processes involved in the water cycle.
• Have students identify the different stages of the water cycle.
• Observe students as they create their water cycle models.
• Ask students to share their models with the class and explain how they work.

Differentiation:

• For students who need more support, you can provide them with a diagram of the water cycle to help them visualize the process.
• For students who are ready for a challenge, you can have them create a more complex water cycle model, such as one that includes a river or an ocean.

Extension:

• Have students research different ways that humans are impacting the water cycle.
• Have students create a presentation or poster about their findings.
