In this lesson children will investigate water vehicles, compare types of vehicles and talk about the function of propellers and anchors
Explain how vehicles that go in the water are different from vehicles that travel on land.
Ask the children to compare a land vehicle (e.g., a car) to a water vehicle (e.g., a boat).
Tell the children that water vehicles often have special elements like propellers that give them
the power needed to move on or under the water, or anchors on a pulley system that help
prevent them from drifting away.
Ask the children to work with a partner to design and build a water vehicle.
Assign each pair of children the task of designing and building a water vehicle with a propeller
or one with a pulley for an anchor.
Once the children have finished building, have each pair present their underwater vehicle to
the group, describing its special element, and explaining what it is used for.
Facilitate a discussion about the children’s water vehicles.
Ask questions like:
Tell the children that some water vehicles go under the water (i.e., submarines), allowing people
to explore parts of the ocean that are not possible to reach in a normal vehicle.
Ask the children to adapt their designs so that their vehicle can go underwater.
Tell the children that people build all kinds of vehicles for different purposes.
Some go underwater to explore the ocean and some go up in the air to do things like transport people,
go on rescue missions, and deliver goods.
Ask the children to work together in their pairs to design and build a flying vehicle like a helicopter, airplane, or even a space shuttle!
Once the children have finished building, have them demonstrate how their models are used.
Observing the following skills can help you monitor whether the children are developing the necessary competencies:
