PSLE Science Experiment Quiz

What is the main focus of the experiment conducted by Fiona?

• To analyze the impact of soil type on plant growth

• To find out if water affects the growth of green beans

• To study the effect of temperature on seed germination

• To determine the effect of light on plant growth

What does the phrase 'to find out' indicate in the context of the experiment?

• The conclusion of the experiment

• The aim of the experiment

• The result of the experiment

• The hypothesis of the experiment

In a fair experiment, how many change variables should there be?

• Two

• Three

• One

• None

Why is setup B and D considered a fair test?

• Both setups are placed in a black box

• Both setups have the same amount of water

• Both setups have different amounts of light

• There is only one change variable: the presence of water

What additional variable is changed in setup C compared to setup B?

• Amount of water

• Presence of light

• Temperature

• Type of soil

Why is setup A and D not a fair test?

• Different light conditions are provided

• Different temperatures are maintained

• Different amounts of water are used

• Different types of seeds are used

What is the change variable in the comparison between setups A and C?

• Presence of light

• Temperature

• Amount of water

• Type of cotton pad

Which setup comparison correctly identifies the presence of water as the change variable?

• B and D

• B and C

• A and D

• A and C

What is the key takeaway from the video regarding fair experiments?

• Always use multiple change variables

• Ensure only one change variable is present

• Change all variables to see different results

• Use different types of seeds for variety

What should be done to other variables in a fair experiment?

• They should be increased

• They should be changed frequently

• They should be ignored

• They should be kept the same
