This will really help students in knowing Scientific Method. It has examples, explanations, exercises and activities.

APPLICATION OF SCIENTIFIC METHOD

2. MELC #1 : Describe the components of a scientific
investigation.
I. OBJECTIVES:
Using technology-aided instructions with the use of
PowerPoint, the Grade 7 students, with at least 85%
accuracy, would be able to:
A. describe how scientific method is observed during
experimentation;
B. present evidences in determinizing experimentation’s set-
up; and
C. show real-life problems where scientific method is best
applied.

3. What do you observe about the illustrations?
How do the sunlight and water affect the growth of the
plant?

4. VARIABLE
is any factor, trait, or condition that can exist in
differing amounts or types.
CONTROL
EXPERIMENTAL
is the group being tested for a reaction to a
change in the variable.
TERMS TO REMEMBER…
DEPENDENT
is the variable being tested in
a scientific experiment.
is an experiment or observation designed to minimize
the effects of variables other than the independent
variable.
INDEPENDENT
is the variable whose change isn't affected by
any other variable in the experiment.

5. SCIENTIFIC METHOD
Make an Observation
Identify/Statement of the Problem
Formulation of the Hypothesis
Test the Hypothesis / Experimentation
Analysis of Data
Conclusion/Communicate Results

6. Hypothesis may be tested in two ways:
a. Null Hypothesis - hypothesis that states no relationship
between variables.
Example: The fertilizer does not affect the growth of
plants.
b. Alternative Hypothesis- hypothesis that states a
relationship between variables.
Example: There is a significant relationship between the
growth of plants and the use of fertilizer.
How does hypothesis being tested?

7. Why do we need to experiment?
Experiment - a procedure to test the hypothesis.
Variables - anything you can change or control in an
experiment.
Does it help in making things work?

8. VARIABLES AND CONTROLS
Kinds of Variables
a. Controlled Variables
• variable that are kept constant. They do not have any
treatment.
b. Independent Variables
• are the factors that you change or alter during the experiment.
c. Dependent Variables
• are the variables that you observe and they are considered the
response to an independent variable.

9. Question:
1.What is the dependent variable?
2.What is the independent variable?
3.How about the controlled variable?

10. CONTROL AND EXPERIMENTAL GROUP
Control Group
• not expose to variable
being tested.
Experimental Group
• expose to variable
being tested.

11. EXAMPLES OF A SITUATION
THAT APPLIES THE SCIENTIFIC METHOD
1. Observation : Brian says something on the microphone but we
heard nothing even though he’s talking to the camera.
2. Problem: Why is Brian not audible?
3. Hypothesis: There is a problem with Brian’s headset.
4. Experiment: Brian checked his headset and he found out that the
wire of his headset has been cut.
5. Analyze: Brian has experienced loss of signal due to his
microphone
6. Conclusion: Therefore, I conclude that Brian is not audible
because there is a problem with his headset.

12. EXAMPLES OF A SITUATION
THAT APPLIES THE SCIENTIFIC METHOD
1. Observation : My cellphone didn’t charge after I plugged it into
the outlet.
2. Problem: Is there something wrong with my electrical outlet?
3. Hypothesis: If something is wrong with the outlet, the
television will not also work when plugged into it.
4. Experiment: I plug the television into the outlet. The
television works.
5. Analyze: Check if what device has a defect.
6. Conclusion: Therefore, I conclude that there is a problem with
my device not the electrical outlet.

13. LET’S TRY THIS :
Observation :
1.Rina suddenly left the meeting
during the online class.
2. I can’t find my wallet.

14. GUIDE
QUESTION:
1. Give a problem based on the observation given.
2. What do you think is the hypothesis of the
problem?
3. How are you going to conduct an experiment to
prove your hypothesis?
4. Give the conclusion based on the data you have
gathered.

15. LET’S WRAP IT UP! I. MULTIPLE CHOICE: Underline the correct answer.
1. It is not exposed to variable being tested.
a. Experimental
b. Control
c. Dependent
d. Independent
2. It s any factor, trait, or condition that can exist in differing amounts or types.
a. Variable
b. Dependent
c. Independent
d. Controlled
3. It is hypothesis that states no relationship between variables.
a. Null hypothesis
b. Alternative hypothesis
c. Both a and b
d. Neither a nor b
4. It is the group being tested for a reaction to a change in the variable.
a. Observation
b. Control
c. Experimental
d. Dependent

16. LET’S DEEPEN MORE :
September 14, 2020
Using Google Classroom, answer the assessment activity to deepen your understanding and
how you achieve the mastery level of the topic.
The link of the assessment activity will be sent right after the session through our class
Group Chat in Messenger and/or in Google Classroom that is more accessible to you to access.
September 14, 2020
Prepare a mongo beans (at least 10 seeds. In A, place it a wet tissue paper and in Place B, place it in
soil. Put the same amount of water into it. Observe what will happen. Use the table below.
Materials: Use tape measure, mongo beans, water, wet tissue paper, soil
For online, submit it on Thursday, September 17, 2020 @ 12:00 NN in a .jpeg format.
Attached it to the Google Classroom and/or email at slagradeict2020@gmail.com.
For modular, submit it on Friday, September 18, 2020 @ 08:00 – 04:00 PM.
Use long bondpaper. Sir Christian
LET’S BRING IT HOME: ONLINE/MODULAR
PLACE # of Seeds Amount of Water Height in Days (cm)
Day 1 Day 2 Day3
A 5 2 mL
B 5 2 mL

17. ONLINE/MODULAR:
I. ASSESSMENT: Answer it in a whole long bondpaper for 10 points each.
1. Why do we need to learn about scientific method? How does it help us acquire knowledge?
2. Why do we need to investigate in solving a problem?
3. How does control and variables helps determine the dependent and independent variable?
4. Is it necessary to formulate a hypothesis? Yes or No. Explain.
I. ACTIVITY: Based on the activity, answer it in a whole long bondpaper for 10 points each.
1. Which grows taller – the mongo seeds in the wet tissue paper or the mongo beans in the soil? Cite
your observation.
2. In a given amount of water, why do you think it is best to determine the factors of this activity?
3. In putting too much water, does it give reason to let the mongo beans grow taller? Explain.
