3. a. Aim or Problem:
● This is the heart of your investigation.
It's the question you want to answer
through your experiment.
A good aim is:
1.Clear and Specific: It should be a
focused question about what you
want to investigate. Don't try to answer
too many things at once.
4. 2.Answerable through an Experiment:
The question should be something
you can test by collecting data.
3.Measurable: You should be able to
measure or observe something
to find an answer.
5. b. Materials and Equipment: This is the list of tools and
supplies you need to conduct your experiment.
Consider these points:
1.Adequacy: You should have everything needed to carry
out your
procedures effectively.
2.Safety: Choose materials that are safe to use and
handle.
3.Availability: Ensure the materials are readily available or
easily
obtainable.
6. c. Method or Procedures:
● This is the detailed step-by-step plan for
conducting your experiment. It outlines exactly
what you will do to test your aim.
● A good method should be:
Clear and Concise: Write specific instructions
that are easy to
understand and follow, even by someone else.
7. Sequential: List the steps in the order they will
be performed.
Repeatable: The method should be written in a
way that allows others to repeat your
experiment and get similar results
d. Results including Data:
This section documents the findings of your
experiment. It includes all the information you
collected during the investigation.
8. Data can be presented in various ways:
1.Observations: Detailed descriptions of what
you saw, smelled, heard, etc., during the
experiment.
2.Measurements: Quantitative data collected
using tools like rulers,thermometers, or
scales.
3.Tables and Charts: Organized presentations
of your data for easier analysis.
4.Graphs: Visual representations of your data
to identify trends or relationships.
9. Conclusions:
● This is where you interpret your results and answer
your initial question(aim).
● A good conclusion should be:
o Based on Evidence: It should be derived directly from
the data you collected during the experiment.
o Explanatory: Explain what your findings mean in
relation to your aim.
o Supports or Rejects: State whether your data supports
or rejects your initial hypothesis (if one was formulated).
