What are factors affecting liquid pressure
Objective:
Design and try out an experiment properly to find a factor affecting a liquid pressure.
Chemicals and apparatus:
1. plastic bottle
2. Balloon
3. Rubber stopper
4. Glass tube
5. Marbles
6. Food coloring
7. Liquid such as water, syrup, salt solution, oil
Procedure:
1. Discuss about factors affecting a liquid pressure.
2. Choose a factor to study, set a question and hypothesis.
3. State the independent variable, dependent variable and, control variables.
3. Design an experiment to test the group hypothesis by using the given chemicals
and apparatus.
4. Perform the experiment, record the data, discuss and conclude the experiment.
5. Present your experiment report.
