Question 1
The picture shows a torchlight .The table shows the ability of the torch light using three batteries to function at different times.

Time(hours)......Brightness of the bulb in torch light
2.......................Brightest
4.......................Bright
6.......................Dim


1. Based on the experiment, state the following variables:

What to change/ manipulated :……………………………………………………….

What to measure/ responding :………………………………………………………….

Kept the same/ controlled : ………………………………………………………….

2. What is the aim of the investigation?

……………………………………………………………………………………………………
3. Suggest one hypothesis based on the table.

…………………………………………………………………………………………………………
4. What is your observation about the brightness of the bulb for two hours?

…………………………………………………………………………………………………………
5 . State your inference based on your observation.

…………………………………………………………………………………………………………

6. What is your conclusion based on the table?

Suggested answers

1. Based on the experiment, state the following variables:

What to change/ manipulated : time

What to measure/ responding : Brightness of the bulb in torch light

Kept the same/ controlled : type of battery, number of battery


2. To study/ investigate the relationship between the time and the brightest of the bulb in torch light.

3. The more the time the more the brightest of the bulb in torch light / if the time increase then the brightest of the bulb in torch light decrease.

4. The brightest of the bulb in torch light is more brightest at two hour.

5. The brightest of the bulb in torch light is more brightest at two hour because there is enough power.

6. The more the time the more the brightest of the bulb in torch light / if the time increase then the brightest of the bulb in torch light decrease.
