## 9. Victoria grows the same bacteria in 20 petri dishes.

Ask: 9. Victoria grows the same bacteria in 20 petri dishes. She places 10 of the
dishes in a container with a normal atmosphere. The remaining dishes she
places in a container in which the oxygen level is double the normal level. She
labels the first group “A” and the second group “B.” Which statement best
describes the groups?
A. Group A is the control group; Group B is the experimental group.
B. Group A is the experimental group; Group B is the control group.
C. Group A is the variable; Group B is the observation.

10. Jackson and Mia want to do an experiment to determine how the
temperature of water affects how much salt can be dissolved in it.
In what order should they perform the following steps?​

There are no options but the question can be answered based on general understanding of experimentation.

Group A: Control group

Group B: Experimental group

There are no options but the question can be answered based on general understanding of experimentation.

Group A: Control group

Group B: Experimental group

Explanation:There are no options but the question can be answered based on general understanding of experimentation.

Group A: Control group

Group B: Experimental group

Explanation:

In an experiment, there are two groups viz: the control group and the experimental group. A control group is the group that does not receive any experimental treatment. It is considered the normal group while the experimental group is the group that is subjected to experimental treatment.

N.B: The experimental treatment in this case is the “Oxygen level”

According to the question, out of 20 petri-dishes used to grow bacteria, half (10) of the petri-dishes were placed in a container with normal atmosphere while the other 10 petri-dishes were placed in another container that have double the normal oxygen level. The first group of bacteria labelled GROUP A are the CONTROL GROUP because they were not given any treatment i.e placed under normal conditions while GROUP B are the EXPERIMENTAL GROUP because they are the group that received the experimental treatment (increased oxygen level).
