Blowing BubblesAdopted from: Nathalie Valencia Chacon
Place the glass inside the basin. Fill the glass halfway with water. Add 1 tbsp. of shampoo to the water. Stir lightly Each person in the group will take a straw. Wait for my instructions. On my go signal, everyone must blow the water
through the straws. Observe what is taking place. Stop blowing when I say so.
Blowing Bubbles
Blowing Bubbles
Using a marker, write your observations in large enough letters to be seen when posted on the board.
Blowing Bubbles
On another sheet/s of paper, complete the following sentence based on your observations or you may make conjectures based on your ideas.
“______________ affect(s) the __________ (of the bubbles).”
You may make several statements. You have 3 minutes to do this. After 3 minutes, post your work on the board.
Blowing Bubbles
In this part of the activity, you will be exploring what happens to the bubbles when some conditions are changed.
You will have to make several decisions
Blowing Bubbles
First, choose one condition that affects the bubbles. This should be the condition that you want to explore by
some manipulation. You must have two or three manipulations in this
condition (such as different magnitudes, with or without something).
Blowing Bubbles
Second, decide what about the bubbles you will observe when you manipulate this condition.
You will be running one trial for each manipulation. But before you do the trials, you must decide what
conditions will be kept the same through different trials
Blowing Bubbles
Then make a tentative guess about what is going to happen to the bubbles when you manipulate this condition.
Blowing Bubbles
Write your decisions/ ideas on a formatted sheet using a marker and post on the board.
After 3 minutes to do this. After 3 minutes, post your work on the board and proceed to the trials.
Blowing Bubbles Format
Condition to manipulative/ explore (only one):
Manipulations (2 to 3)
What to observe about the bubbles:
Conditions that will be kept the same during trials:
Tentative guess at to what will happen (complete sentence)
Blowing Bubbles After the Trials
Write a brief report on your observations using a marker. The statement must contain – The condition you manipulated The different manipulations What you have observed about the bubbles during the
trials The conditions you have kept the same during the trials.
You have 5 minutes to do this. Post your work on the board.
Blowing Bubbles
This activity was adapted from the material included in the students as Scientist Training (Costa Rica) by Nathalie Valencia Chacon.

Variables in Research
properties being investigated, or conditions being manipulated or varied
signified a property or a factor whose changes can be measured

Variables
Variables
Dependent
variable
Extraneous variable
Independent
Variable
(Experimental, Manipulated,
Treatment , Grouping)
Manipulated, measured, or selected by the researcher as an antecedent condition to an observed behavior
In cause-and-effect relationships, the independent variable is the cause
Independent
variable
(Outcomes or Responding)
Factor which is observed and measured to determine the effect of the independent variable
Factor that appears, disappears, or varies as the experimenter introduces, removes, or varies the independent variable
Dependent
variable
Dependent

Extraneous Variable
The parts of the experiment that remain the same
Factors must be kept constant in all experimental runs
