Essential Question:
How do I Identify
the parts of an
experiment?
Reminders:
1. Follows instructions.
2. Formulate your hypothesis.
3. Record all observations. You can take pictures
or recordings of your experiment using your
devices.
4. Identify the parts of the experiment.
5. Make valid or objective conclusions.
Gropuping:
1. choose the leader of the group.
2. Choose a secretary or recorder.
3. Choose who will be performing the steps,
together with the leader.
4. Choose one to take pictures.
5. Choose who will clean up after the
experiment.
Merits and Demerits
•Did all steps accurately +2
•Did all steps accurately without
accidents +5
•Broken egg
-5
•Spilled water -5
Formulating your hypothesis:
I.Investigative Question:
How can I make an egg float?
Hypothesis:
I dissolve enough salt in the water then
If _______________________,
the egg will float
_____________________________
? Research!
because______________________
1.Fill both
cups with
¾ full of
water.
A
B
2.Label the first cup as Set up A
and the second cup as Set up B.
A
B
Set up A is your control group.
Set up B is your experimental group.
B
3.Pour salt
in set up B.
Do this
slowly and
carefully.
4.Do not
pour salt
in
Set up A.
Dissolve the salt complety in 20 seconds!
B
5. Hold and secure
the cup of Set up B
and gently stir the
water for
20 seconds.
Be careful not to spill the water!
A
6. Hold and secure
the cup of Set up A
and gently stir the
water for
20 seconds.
Be careful not to spill the water!
Set Up -A
7. Slowly drop the egg in Set Up A. Do not splash!
Set Up -B
8. Slowly drop the egg in Set Up B. Do not splash!
I.Experimental Design –
How will you test your hypothesis?
List the steps of the
experiment.
Formative
assessment
Identify the control and
experimental group:
(A or B)
Why was it important
to label your set-ups
(control and experimental
or set up A and B)
Why did you
have two setups?
What happened when
you mixed the salt in
set up B?
What was the
function of set-up
A (control group)?
Identify the independent and
dependent variables.
Independent variable
What did you change in the set up B?
Dependent variable/s
What was the result or consequence of the
change?
Conclusion:
Was your hypothesis
correct or not? What
did you discover?
How do I Identify the parts of an
experiment?
• The control group is the part of the experiment that remains
the same.
• The experimental group is the group that is being
experimented on.
• The independent variable is the change you are making to
the experimental group.
• The dependent variable is the result that occurred from the
experimentation.
