Make Lakes, Rivers, Plains, and Oceans

Time: 20 minutes

Goal: Your child will make a simple land-and-water model and identify a lake, river, plain, and ocean.

Materials

• A shallow tray, baking dish, or piece of cardboard
• Play dough, modeling clay, or crumpled paper and tape
• Blue paper, blue crayons, or a small amount of water
• Green or brown paper/crayons
• Four small labels or sticky notes: lake, river, plain, ocean

Activity

1. Hook—Where does water go? (2 minutes)

   Ask: “If rain falls on land, where might the water collect or flow?” Explain that today you will build a model showing four kinds of land and water.

2. Show it—Make the basic shapes (4 minutes)

   Use the materials to demonstrate:

   • Ocean: Make a large area of blue at one edge of the tray. Say, “An ocean is a very large body of salt water.”
   • Plain: Make a wide, mostly flat area beside the ocean. Say, “A plain is a large area of flat land.”
   • River: Make a thin, winding blue line flowing from the land toward the ocean. Say, “A river is moving water that flows from one place to another.”
   • Lake: Make a smaller, rounded blue area surrounded by land. Say, “A lake is water surrounded by land.”
3. Make it together (6 minutes)

   Build the model with your child. Ask:

   • “Can you make the ocean bigger than the lake?”
   • “Can you make the river wind across the plain?”
   • “Can you surround the lake with land?”
   • “Which part is flat land?”

   Place each label on the correct part of the model.

4. Your child makes and explains it (5 minutes)

   Have your child rebuild or improve the model independently. Ask them to point to each feature and complete these sentences:

   • “This is a lake. It is __________ by land.”
   • “This is a river. Its water __________.”
   • “This is a plain. It is mostly __________.”
   • “This is an ocean. It is a very __________ body of water.”

   Expected words: surrounded, flows, flat, large.

5. Quick recap (3 minutes)

   Mix up the labels and ask your child to place them correctly. Then ask: “What is one difference between a lake and a river?” A correct answer is: “A lake is surrounded by land, while a river flows.”

Quick Check

Ask your child to draw one small picture containing a lake, river, plain, and ocean, and label all four.
