Question

Materials needed:
Fizzy tablets Timer
Measuring cup Cup
Bowl of water pencil/paper to record data


Identifying the Variables:
Independent Variable:


Dependent Variable:


Control Variable(s):

Answer 1

In the context of an experiment involving fizzy tablets and their reaction in water, identifying the variables is essential for a clear understanding of what is being tested. Here’s how you might identify them:

### Independent Variable:
- The **independent variable** is the factor that you change in the experiment. For example, the different types or brands of fizzy tablets you are using (if testing various kinds) or the amount of water (if varying volumes of water).

### Dependent Variable:
- The **dependent variable** is what you measure in the experiment. In this case, it could be the time taken for the tablet to fully dissolve in water or the amount of fizz (bubbles) produced over time.

### Control Variable(s):
- **Control variables** are the factors that are kept constant throughout the experiment to ensure that the results are reliable. This includes:
- The temperature of the water
- The size and type of the fizzy tablet (if testing just one type, keeping it consistent)
- The volume of water (if this is not the independent variable)
- The type of container used (if it affects the reaction)

Make sure you apply these variables based on the specific aim and design of your experiment!
