How scientists design an experiment

Multiple Choice

What is the purpose of science experiments?

• Because they're lots of fun

• Answering questions we have on our minds on how/why certain things happen

• Figuring out how to change the colour of test tubes

• Reading from a science book

Multiple Choice

What is the purpose of the Title?

• Name of the experiment

• To make the experiment sound cool

• Name of the scientists

• Name of the item being tested on

Match

Match the following:

• Hypothesis

• Method

• Aim

• Variables

• Discussion

Predicting what you think will happen.

Steps followed to conduct the experiment

Explaining the purpose of the experiment

Multiple Choice

What is wrong with the experiment?

• The method to measure the experiment wasn't too effective.

• The experiment is too simple, everyone already knows the answer

• The materials aren't good enough

• The experiment is too easy to understand

• There's more than one independent variable

Multiple Choice

What could affect the health of a plant?

• The temperature

• The amount of sunlight

• The quality of the soil

• All of these things

​There is more than one variable!

Every science experiment should have only ONE independent variable!

Multiple Choice

This is the variable that we change

• Controlled

• Dependent

• Independent

Multiple Choice

This is the variable that we measure

• Controlled

• Dependent

• Independent

Multiple Choice

This is the variable that we keep the same

• Controlled

• Dependent

• Independent

​The Controlled Variables

​The controlled variables are all

of the parts of the experiment

that you keep the same.

​​E.g. The same: plant, soil, pot,

temperature, sunlight.

​

​The controlled variables help us to

​know how ONLY our independent variables will affect the experiment.

​e.g. how the water affects the plant, but not the other things.
