Identify which one is best sentence to have in your method (LOOK AT THE TENSE!)

Measure the temperature of the water using a thermometer.

small and unavoidable variations when making measurements

Something that could be avoided if you are more careful.

Karen wanted to see which type of fertliser makes plants grow the tallest. One variable is the:

Fertiliser changed: plant height measured.

How much do fertlisers effect a plant? How much fertliser would be best to add in this test?

Strict amounts. E.g. 0 grams, 5 grams and 10 grams.

AIM: To find out if snails remember a path leading to food. Which is the best conclusion?

Snails cannot remember a path that leads to food.

We are going to measure the temperature of the water.
A thermometer measured the temperature & it was 25 degrees.
Measure the temperature of the water using a thermometer.
We measured the temperature of the water

6
After they finish their tests, scientists must _______________ the results.
test again
analyze
question
disregard
7
An error is:
when the independent variable is wrong.
something that could be avoided if you were more careful.
small and unavoidable variations when making measurements
When you muck it up totally and have to redo the experiment
8
A mistake is:
Small & unavoidable variations when making measurements.
Only little, and you can continue on the experiment
Something that could be avoided if you are more careful.
when the dependent variable is wrong.
