Photosynthesis Warm Up
How do plants get energy and mass?
• Sunlight• Water• Carbon Dioxider
Where plants get their mass?
Where do plants get their mass?
Do gases have mass?
• Does the air weigh anything?
• Does the oxygen we breathe in weigh anything?
• Does the carbon dioxide in the air weight anything?
The majority of the mass in a plant comes from…..
• CARBON DIOXIDE!!!
• But how do we know?
Design an Experiment
• With your elbow partner, you will have 30 minutes to design an experiment (or more than 1) to show that the mass in a tree comes from carbon dioxide.
• Use the outline provided and summarize your experiments into an essay on the poster provided to present to your classmates.
Scientific Method Review
• What items do we need to identify while designing an experiment?
• How can we make our results more reliable?
