Learning Experience Plan (LEP) for a science activity for children

Sample Solution

Learning Experience Plan (LEP) for a Science Activity: Exploring Sink or Float

Age Group: 2-8 years old

Learning Objectives:

• Children will be able to identify and name common objects that sink or float.
• Children will be able to make predictions about whether objects will sink or float based on their properties.
• Children will be able to explain that objects sink or float because of their density and buoyancy.

Materials:

• A large container of water (such as a bathtub or a plastic bin)
• A variety of objects, some of which will sink and some of which will float (such as toys, balls, sponges, rocks, and leaves)
• A container for collecting objects

Procedure:

Introduction (5 minutes):

1. Gather the children around the container of water.
2. Ask the children if they have ever seen something sink or float in water.
3. Explain that some objects sink in water, while others float.
4. Show the children some examples of objects that sink and objects that float.

Exploration (20 minutes):

1. Invite the children to explore the objects and predict whether each object will sink or float.
2. Have each child choose an object and place it in the water.
3. Ask the children to observe what happens to the object.
4. Record whether the object sank or floated.
5. Repeat steps 2-4 with the remaining objects.

Discussion (10 minutes):

1. Gather the children around the container of water.
2. Ask the children to share their observations about the objects that sank and floated.
3. Explain that objects sink or float because of their density and buoyancy.
4. Density is how much mass is packed into a certain volume. Objects that are more dense than water will sink, while objects that are less dense than water will float.
5. Buoyancy is the upward force that water exerts on an object. Objects that are buoyant float because the upward force of the water is greater than the weight of the object.

Application (10 minutes):

1. Ask the children to make predictions about whether new objects will sink or float.
2. Have each child choose a new object and place it in the water.
3. Ask the children to observe what happens to the object.
4. Discuss the children's predictions and observations.

Assessment:

• Observe the children's ability to identify and name objects that sink or float.
• Observe the children's ability to make predictions about whether objects will sink or float.
• Observe the children's understanding of the concepts of density and buoyancy.

Differentiation:

• For younger children, provide more assistance with identifying objects and making predictions.
• For older children, provide more challenging objects to explore and encourage them to explain their predictions in more detail.

Extension Activities:

• Make a sink or float chart to record the children's observations.
• Experiment with different types of water, such as saltwater or freshwater, to see how it affects the sinking and floating of objects.
• Read books about sink or float.
• Play games that focus on sink or float.
