• We decided to focus on light

• Our Aim - to find out if the colour of the light would

affect the growth of the plant.

• Key theme of the project – plants

photosynthesising to help the astronauts in

space.

• It interested us!

• Research told us that it would be an effective way to

grow plants.

• We have previous knowledge

of which lights plants absorb.

• Blue and red acetate.

• Cress seeds

• Soil

• Plastic tubs

• Seed trays

• Lamp

• Pipettes

• We did the experiment twice, to double check

our results.

•3 is the magic number.

(3 times is always best!)

• Control variable

Test on different plants.

Continue using blue light.

Control the control variable more tightly.

We used a

smart phone

app to monitor

light intensity

under all three

boxes.

• Plants left in different positions

• Buckwheat needed different conditions to grow

• Couldn’t get accurate readings with measurements

• Couldn’t control temperature

•Just concentrated on Cress.

•Left the plants in the same

positions with the same light

intensity.

•Same number of seeds in

each tray.
