The document describes the scientific method and its steps. It begins by explaining that science is a way of thinking and gathering knowledge about the world that is accurate and reliable. It then outlines the key steps of the scientific method: 1) make observations, 2) come up with a question, 3) develop a hypothesis, 4) conduct an experiment to test the hypothesis, 5) record and analyze results, and 6) draw conclusions. It provides an example of using this method to test if eggs will float or sink, depending on the density of the surrounding water.

6. Science is a way of thinking and a way of gathering
knowledge about the world that is both accurate and
reliable.
It is the quest to understand and improve our
knowledge of the world around us, and how the things in it
work or why they work the way they do.

8. Objectives
After going through this module, you are
expected to:
• Identify the steps of a scientific method;
• use the scientific method in solving problem
through an experiment; and
• Relate scientific method in daily life.
Scientific findings 8

9. What is the scientific method?
The scientific method is like the road map that you follow to get to that
destination. It is the process by which science is carried out, as in other areas of
inquiry; science through scientific method can build on previous knowledge and
develop a more sophisticated understanding of its topics of study over time.
Scientific findings 9
It is the steps someone takes to identify a question, develop a hypothesis,
design and carry out steps or procedures to test the hypothesis, write down
data, and draw a conclusion.
In other words, it’s a way to solve a problem.

10. Think like a scientist……
• Scientist take time to
think logically when they
are investigating a
question or problem.
• They break things
down into many
steps that make
sense.

11. Steps of the Scientific Method

12. Make observations
• There are tons of everyday activities that would make cool
science experiments using the scientific method.
• A student noticed that some objects float in water but some
are not
Scientific findings 12

13. Come up with a question
• The students’ observations should lead to some sort of questions.
Have you ever wonder why some objects float in the water but
some sinks?
Scientific findings 13

14. Develop a hypothesis or prediction
• You have made your observations and you have your
questions. Now you need to make a prediction about what
you think will happen next.
• A hypothesis is not simply a guess! A hypothesis is an
educated guess or tentative answer to a problem.
According to the research it has something to do with the
density of the water and the object.
Scientific findings 14
For our hypothesis:
Anything that has a higher density
compared to the water will sink into
the water

15. Variables
• Identifying and controlling variables
involve the process of deciding
which variables or factors will
influence the outcome of an
experiment; situation or event and
deliberately control all recognized
variables in a systematic manner.
• Variables in an experiment may be
independent or dependent. The
variable that is being manipulated or
controlled is called independent
variable. The dependent variable
changes because of a test. It is the
effect that arises from the changes in
the independent variable.

17. CONDUCT AN EXPERIMENT OR TEST THE
HYPOTHESIS
• We made a prediction that is higher density compared to the water will
sink into the water
• For the best experiments, only one thing should change.
Scientific findings 17
What to use:
Water
Salt
Transparent glass
Eggs
spoon

18. RECORD AND ANALYZE THE RESULTS
• Make sure to record what is happening as well as
the results. As you can see the egg floats in the salt
water. The reason why the egg sinks in the fresh
water is that the density of the egg is higher than the
density of the water with no salt or anything else,
when salt was added to the fresh water the density
of the water becomes higher than the density of the
egg
• Was your prediction accurate? If it is not accurate,
state the reason/s.

19. DRAW CONCLUSIONS
• This is the opportunity to talk about your hypothesis, your experiment,
your results, and your conclusion which is the final answer to your
problem or experiment!
