Absorbency

What is a hypothesis?

• An idea or explanation that you can test through study and experimentation.

• The information you obtain from your experiment

• Something you don’t understand but you can do an experiment to help you understand.

What is the procedure of an experiment?

• What you see happening with the materials. (see, touch, feel)

• Step-by-step instructions for completing the experiment.

• An idea or explanation that you can test through study and experimentation.

What are observations?

• An idea or explanation that you can test through study and experimentation.

• Something you don’t understand but you can do an experiment to help you understand.

• What you see happening with the materials. (see, touch, feel)

What are the results of an experiment?

• The information you obtain from your experiment

• Step-by-step instructions for completing the experiment.

What makes your experiment a FAIR TEST?

• My mother says I'm a very fair person.

• All the VARIABLES were the same. The pieces of materials were the same size and the amount of water I used was the same.

• I decided how big each piece of paper should be, I made some bigger as I liked the colour.

• All of the above answers are correct.

When I did my experiment, to make sure it was a FAIR test, I did the following?

• Kept to the correct time for each test.

• Cut all the materials used the SAME size.

• Used the same amount of water for each test.

• ALL OF THE ABOVE.

For your absorbency experiment, we used VARIABLES, which ones stayed the same? The ones thats I keep the same are called CONTROLLED variables.

• time, size of material, fun.

• time, size of material, different kind of liquids

• time, size of material, same amount of water used.

• time, different sizes of materials, fun
