Answer 29

Include amounts, brands (if important) and be as specific as possible

Question 30

What procedures will you need to do?

Answer 30

Write out every step that was taken, start with an action word, include every step so that someone could replicate the experiment, and lastly make a numbered list.

Question 31

When designing experimental procedures what must you always consider?

Answer 31

Experimental and control groups

Question 32

What is an experimental group?

Answer 32

groups that are being tested

What is an control group?

Answer 33

The group used for comparison “the normal group”

Question 34

What are constants?

Answer 34

The aspects of an experiment that are held constant/consistent. It ensures that all aspects of the trial are identical except for the IV

Question 35

How many trials should you have and why?

Answer 35

As many as possible to ensure the results aren’t by chance, to eliminate any potential errors and ensure the data is precise.

What is data?

Answer 36

Collected data that is in an organized form during the investigation and easy to read (such as a graph)

Question 37

What is a analysis?

Answer 37

Only makes stamens about what the data shows, highlights any trends or patterns seen in the data, discusses any potential errors in the data.

Question 38
