Question 18

Science of the tree (no. 18 - 20)

Have you been to a park or a forest before? Do you know, trees can be as high as 20 storey building? Trees may live for hundred of years and create a nice environment in the city park. They need water and mineral like other organism to grow.

As you learn from the physics, water flows to the lower area, but water can travel to the top of the tree? Could you explain this phenomenon?

Question 19

Science of the tree (no. 18 - 20)

Have you been to a park or a forest before? Do you know, trees can be as high as 20 storey building? Trees may live for hundred of years and create a nice environment in the city park. They need water and mineral like other organism to grow.

If you sit down under the tree during day time, you can breathe freshly. However, you should not put green plants in your room during night time.
a. Can you explain why?
b. What you should do to keep the green plants in your room during night so the plant can produce oxygen?

Question 20

Science of the tree (no. 18 - 20)

Have you been to a park or a forest before? Do you know, trees can be as high as 20 storey building? Trees may live for hundred of years and create a nice environment in the city park. They need water and mineral like other organism to grow.

Trees are important for human being and also for the existence of ecosystem. Would you write one example of how trees can be used by other organism so that this interaction gives benefit to human being.
