Bell work
• WS How Cells Work: Respiration
• Go over above WS
• Pass in Venn Diagram
Photosynthesis and Respiration
• Photosynthesis and Respiration together form a cycle known as the oxygen and carbon dioxide cycle
• The reactants and the products are opposites
Demonstration – Exhaling Carbon Dioxide
• Bromthymol blue – is an indicator for carbon dioxide
• What is the initial color of the liquid?
• What is the final color of the liquid?
