PEKA Science

You are required to do experiment 1.23(Longman Science Process Skills Form 2)

Example PEKA Report:

Topic : Response of plants towards Light

Aim : To study the response of the shoots of plants towards light

Hypothesis : The shoots of plants grow towards light

Variables :
a) is kept constant : Type of seeds
b) is manipulated : Direction of light
c) responds : Response of the shoot

Materials and Apparatus : Green bean seeds, box, wet cotton, evaporating dish

Procedures:
1) Two days before starting the experiment, three to five green bean seeds are left to germinate on wet cotton wool in two evaporating dishes.
2) Evaporating dish P containing green bean seedlings is placed under sunlight.
3) Evaporating dish Q with its seedlings is placed in a box which had a hole at the top and also left under the sun
4) The apparatus are left for three days. Observations are recorded and drawn at the end of the experiment.

Observation:
(draw the figures in blank A4 paper)

Analysis:
(copy and answer the questions)

Conclusions:
The shoot of a plant grow towards light
