Mealworm

Experiments:
Aim: What you want to find out
Hypothesis: Predicted results
Variables:

• Dependent: variable that changes as a result of a change in the independent variable.
• Independent: variable that is being changed by the investigator

Constants: Factors that remained unchanged throughout
(controlled variables)


Data recording: 
Table 1: Distance moved by mealworms when placed on a rough surface and a smooth surface.

Observation of mealworms based on 5 senses:

Mealworm experiment:

Aim: to find out if the mealworm would crawl faster when touched by a rough or smooth object

Hypothesis: Mealworms will crawl faster when touched by a rough object compared to when touched by a smooth object

Materials:

• Mealworms
• Cotton bud (smooth)
• Paintbrush (rough) 
• Stopwatch (to keep track of time) 

Procedure:

1. Record the distance the mealworm A crawls when touched by the cotton bud in 5 seconds.
2. Repeat step 1, this time replacing the cotton bud with a paintbrush
3. Repeat step 1 and 2 one mealworm B and C.
4. Calculate the average distance crawled and record it in a table.

Variables:
Independent variable -  The object (cotton bud and paintbrush)
Constant variable - The mealworms, the location, the cotton bud and paintbrush used is the same, the amount of time
Dependent variable - The distance the mealworm crawls


Observation:
The mealworms crawled a greater distance when touched by the paintbrush for 5 seconds compared to when touched by a cotton bud for 5 seconds.


Some of the assumptions made:
The amount of force used to touch the mealworms is the same. The mealworms moved at the same speed when not touched. 


Reliability of the data:
The data is reliable. This is because I conducted the experiment twice, to make sure that the results are accurate and reliable. The experiment was also conducted on 3 mealworms  instead of 1 mealworm so that I can get a average distance. Therefore, the data is reliable.
