Keeping the exact same set-up for your aquarium and probes as initially tested, set the software to record both the pH value and light level at the same time for a 24-hour (86400 seconds) period.
The whole class should start the collection at the same time.
After the collection is complete (on the next day), transfer your data into your spreadsheet. Refer to
Technical Hints to see how to transfer your data to your spreadsheet.
Create different types of graphs to display the relationship between pH and light. Refer to
Technical Hints to see how create graphs for your aquarium data.
Share your data with other groups so that all groups have data from all types of aquariums. Create several graphs to display the relationship between pH and light for all types of aquariums. Refer to
Technical Hints to see how create graphs for your aquarium data. Discuss the relationship between light and pH with your group.
