1.
What do you want to find out? (Aim/Purpose/Research question)
The aim of the experiment is to find
out whether mealworms would choose to live in dark or bright conditions.
2. What is the tentative explanation of
your research question? (Hypothesis)
The mealworms will mostly remain in
the dark.
3.
In an
investigation, there is only one
variable to be changed. Which variable will you change in this
investigation? (Independent Variable)
The independent variable is the presence of light.
4.
All the
other variables must be kept constant.
List a few important variables that will affect the results greatly. (Controlled Variables)
The controlled variables are the number of
mealworms on each side (bright and dark) initially, the amount and type of food
on both sides.
5. What results will you measure? (Dependent Variable)
The dependent variable is the number of mealworms
on each side at the end of the experiment.
6.
State the
assumptions that you have made
The assumptions are the dark side has no exposure
to light, the bright side has no dark patches, there is an equal amount of food
on both sides and all 4 mealworms are similar. If there are more mealworms on a
particular side, the mealworms prefer that particular side.
7.
List the
materials and apparatus that you will need to carry out the investigation.
(Materials and Apparatus)
Materials and Apparatus:
C 4
mealworms
C A
plastic container
C Some
food for the mealworms
C Strong
light
C Some
cloth
C A
shelf with ample space to keep the container underneath

8. List the steps that you will take to carry out the
investigation. (Procedure) Include
drawing of setup.
Procedure:
Step
1: Place the food in the container evenly.
Step
2: Place half the box under strong light and place the cloth over the remaining
half. To ensure that no light enters the dark portion, shift the dark half
under the shelf.
Step 3:
Place 2 mealworms onto each side of the container.
Step
4: Observe their movements in a daily interval basis over 3 days.
9. Data collection and organization. (Results)
The data can be presented in the form
of tables and/or graphs.
Results: After 3 days, 3 of the 4 mealworms were in
the dark section of the box. They have moved towards the light but then avoided
it later.
10.
Explain
what your data means. (Data Analysis)
What did you observe and give reasons
to your observations.
Data Analysis: This means that the mealworms prefer
dark conditions as there are more mealworms on the dark side and if there are
more mealworms on a particular side, then they prefer that living condition
11.
What can
you deduce from the discussion of your data analysis? (Conclusion)
State if your data support your
hypothesis? If not, what would you do? In other words, how can you further
improve your design? What do you think have been carried out incorrectly and
affected the data collected?
Conclusion: My hypothesis has been proven right and
Mealworms prefer dark to bright conditions.
Drawing of a mealworm:
Characteristics of the mealworm:
Number of segments: 12
Length of mealworm: 3.5cm
Colour: Brown
Other distinguishable characteristics: Head and
end of body is darker in colour. It has 6 legs, 2 antennae and distinct
divisions that show its segmented body.
