This document provides an overview of a science lesson on conducting scientific investigations and fair testing. It discusses the key components of a scientific investigation including the aim, method, results, and conclusion. It then provides an example of a student, Gabriel, designing an experiment to test if balloon size increases with rising temperature. It asks questions about how Gabriel should conduct and document the fair test. The purpose is to help students understand what fair testing means in science and remember the parts of a scientific investigation.

fair tests otherwise the results might
not be valid.
12. Lesson Purpose and Intention
Describing and writing the
components of a scientific
investigation.
How important this is for learning and
when answering questions in science.
17. Gabriel blew up some balloons with air and tied them along a
fence in his backyard to see what happened to them in
sunlight. Some balloons were in the shade of the tree.
Gabriel wondered why some balloons started to get bigger –
some even got so big that they popped when they got very hot.
“I think the balloons are getting bigger when the temperature
is getting higher.” He said to himself. “I wonder what
experiment I could do to find out the answer and make sure
it’s a fair test?”
Q1: What should Gabriel use to measure the air temperatures?
Q2. How should Gabriel work out/ measure the size of the balloons
accurately?
Q3: What are some of the things that Gabriel needs to make sure that they
stay the same during his experiment so that it’s a fair test.
18. Q1: What should Gabriel use to measure the air
temperatures?
Q2. How should Gabriel work out/ measure the size of
the balloons accurately?
Q3: What are some of the things that Gabriel needs to
make sure that they stay the same during his experiment
so that it’s a fair test?
22. How should he work out the size of
the balloons accurately?
measure the size of the
balloons by weighing
them three times.
23. Question 3:
What are some of the things
that Gabriel needs to make
sure that they stay the same
during his experiments so
that it’s a fair test?
24. What are some of the things that Gabriel needs to
make sure that they stay the same during his
experiments so that it’s a fair test?
must be the same type and the same size to
begin with.
use the same scales to weight the balloons .
the same thermometer to measure the
temperature each time.
do the experiment all on the same day so that
the weather conditions are the same.
25. Fair Testing
Gabriel blew up some balloons with air and tied them along a
fence in his backyard to see what happened to them in sunlight.
Some balloons were in the shade of the tree.
Gabriel wondered why some balloons started to get bigger – some
even got so big that they popped when they got very hot. “I think
the balloons are getting bigger when the temperature is getting
higher.” He said to himself. “I wonder what experiment I could do
to find out the answer and make sure it’s a fair test?”
26. ● Q4. How should Gabriel write down all his
measurements?
● Q5. What is Gabriel’s aim for the experiment?
● Q6. If Gabriel’s experiment works out, how he
thought it would what should he write as his
conclusion?
30. What is Gabriel’s aim for the
experiment?
to prove that helium
balloons expand and even
burst/pop when the
temperature rises
31. Question 6:
If Gabriel’s experiment
works out how he
thought it would, what
should he write as his
conclusion?
32. If Gabriel’s experiment works out how he
thought it would, what should he write as
his conclusion?
The results showed that as
the temperature increased
by x degrees, the size of the
balloons increased till they
burst.
33. Q1: What is the aim of the investigation?
Q2. How should you measure the height of the plant?
Q3: What are some of the things that you need to make
sure that they stay the same during the experiment, so
that it’s a fair test?
TRY this:
You would like to know if commercial fertilizer
helps a plant grow taller.

Ang love kailangan din ng FAIR

CONCLUSION.
THE IMPORTANCE OF FAIR TESTING
Scientific investigation is a procedure of steps with the goal of problem solving and information gathering.
Scientific investigation is like a ladder, staircase and mobile games.

Ask students to write down their answers on their worksheet.
Ask students to volunteer to read out their answers, giving positive feedback. Read out a sample answer for all students to listen to and write down. This may come from the students or from the sample answers:
A fair test is an experimental design that helps ensure that only one factor or variable in the experiment is changed while keeping everything else the same.
Conducting a fair test is one of the best practices of experimental research because it helps prove that the outcome is attributed only to the manipulated variable.
AIM. Ask a question.
METHOD. What to do/procedure.
RESULTS. What you measured/data.
CONCLUSION. What you learned.

We want to be sure we know and understand about fair testing.
Fair testing is an investigation where one variable (the independent variable is changed and all other conditions )
And controlled variables are kept the same; Now, what is measured or observed is referred to as the dependent variable.
Read out the following names of headings for a science investigation (from the students’ worksheets) and ask the students to read them to themselves and then out loud as a class.
Ask the students to complete the task below by watching the headings with their role/purpose. Explain that they are to use arrows to complete the matching/task. Ask students to provide answers and discuss where needed.
Refer students to the main lesson stimulus and read out the text.
Ask students to reads the text to themselves.
Teacher to read first, then students.
Ask the students if there are words that they are not familiar with (such as balloons, backyards, etc.) and give descriptions of any words that may be problematic.

Answer: All the balloons he is using must be the same type and the same size to begin with.
He must use the same scales to weight the balloons and the same thermometer to measure the temperature each time.
He must do the experiment all on the same day so that the weather conditions are the same for all the measurements.
