Transport of water
Life support: Direct water flow to plants
This unit is designed for children 9 – 10 years old.
Teacher invites pupils into the Engineer project in lesson 1. The unit starts with a story about a boy to moves to another planet to build a settlement there. Pupils learn about importance of the plants for all forms of life. Plants can accept energy from the Sun and change it into chemical substance. Pupils find connection between food and plants.
In lesson 2 pupils draw a plan for building a greenhouse. The greenhouse needs to provide plants with everything they need to grow. So pupils learn to know what plants need. The pupils undertake an experiment on the transport of up water in plants and with materials which soak water.
Lesson 3 is the main construction lesson. Pupils select materials which they are going to use. The story gets to the point, where the main character needs to solve the problem of how to transport water without using energy to survive on the another planet. Pupils build their a construction to transport water.
Pupils evaluate their constructions in lesson 4 and they discuss possible improvements. They also try to draw a draft of their construction.
