Unit 3B: Do Plants need leaves to grow? L.O. 2, 3, 4, 5: N.C
Unit 3B: Do Plants need leaves to grow?
What parts make up a plant?
roots
stem

Unit 3B: Do Plants need leaves to grow? L.O. 2, 3, 4, 5: N.C
Unit 3B: Do plants need leaves to grow?
We have a number of geraniums. How do you think we can use them to see if the leaves are needed for the plant to grow?
How can we measure how much each plant grows?
How can we record these results?Can you put these into a chart or graph?What do your results tell you?
Unit 3B: What do the roots do? L.O. 6, 7, 8, 9: N.C.
Unit 3B: What do the roots do?
What do the roots do?
Roots soak up the rainwater
Water travels up the stem to the leaves
Rain falls and soaks into the ground
Unit 3B: What do the roots do? L.O. 6, 7, 8, 9: N.C.
Unit 3B: What does the stem do?
What does the stem do?

Do you think that each of the seeds will grow the same if you add the amounts of water each day? We will measure the plants every 2 days
We know plants need water to be healthy. But can they have too much water?
No water 5 cm3

Unit 3B: Water, water everywhere: L.O. 11, 12, 13
Unit 3B: Water, water everywhere
Do all the seeds grow the same?
Can too much water be added to a plant?
What evidence do you have for this?
How did you keep the test fair?
Unit 3B: How much evidence do we need? L.O. 14: N.C.

Unit 3B: How much evidence do we need?
How many seeds do you think we should use?
Why do you think this?
How many days do you think is enough days?
Why do you think this?
