Experiment 1 - Effect of changing temperature on the number of oxygen bubbles
Experiment 2 - Effect of the colour of light on the number of bubbles
Experiment 3 - Effect of the amount of carbon dioxide on the number of bubbles
Experiment 4 - Effect of the light intensity on the number of bubbles
Experiment 1 - Effect of changing temperature on the number of oxygen bubbles
- Have light intensity (white light) and CO2 at a maximum
- Change the temperature by clicking on the thermometer
- Record your results in a table and draw a graph
Experiment 2 - Effect of the colour of light on the number of bubbles
- Have temperature, light intensity and CO2 at a maximum
- Change the the colour of light by clicking on the lamp switch
- Record your results in a table and draw a bar chart
Experiment 3 - Effect of the amount of carbon dioxide on the number of bubbles
- Have temperature and light intensity (white light) at a maximum
- Change the the amount of CO2 by clicking on the bottle
- Record your results in a table and draw a bar chart
Experiment 4 - Effect of the light intensity on the number of bubbles
- Have temperature and CO2 at a maximum. Use white light.
- Change the the light intensity using the dimmer switch above the bulb
- Record your results in a table and draw a line graph
