Photosynthesis and Limiting Factors? Wednesday, 11 January 2017 Jobs: Manager, cutter, colourer, assembly, quality control. Shop: Scissors: 2 T-shirts Crayon: 1 T-shirt each Sell tape: 1 T-shirts Patterns: 1 T-shirts. The T-shirt Factory Work as a team to make as many T-shirts as possible. At the end of each work period you need to decide what tools you need to be more efficient. You may then buy more tools if you wish. The winning team is the one which produces the most T-shirts at the end. Sellotape tab •T-shirts must have a front and a back that align. •The design must be coloured in well. What happened? What held you up initially? What was the most effective thing to buy? Was it always the same factor which held you up? If you could change one thing at the start what would it be? Photosynthesis Plants make their own food Carbon dioxide + Water  Glucose + oxygen You need to identify a science area for improvement. This forms part of your next steps to achieving your target grade. Consider the skills below. Rank them in order of need for you as an individual. Areas I need to develop....... From each group you need to assess the individual needs and allocate a person to each skill. Skill to develop this lesson. Extracting information and evaluation skills Graph drawing, data handling and evaluative skills. This will really help with the up an coming ISA paper 2 Biological drawing and mapping of processes e.g. photosynthesis Biological design. Linking ideas and problem solving Rank From your groups you will need to send one person to each activity. You will need to decide who goes where Circus of Activities to recap limiting factors and photosynthesis Activity No Activity title Skill it will develop 1 Seawater greenhouses Extracting information and evaluation skills 2 Limiting factors Graph drawing, data handling and evaluative skills.

Linking ideas and problem solving Space Station Farming You are part of a team designing a lunar space stations. Your task is to design the agriculture module which will provide all of the fruit and vegetables for the colony. Design the module to help the plants grow as fast as possible. Label and explain your design features. True or False The most important factor to a plant is the light intensity? The limiting factor on the rate of photosynthesis is always the factor in shortest supply. False – it depends True Only 0.04% of the air is CO2. On a hot, sunny day the best way to increase the rate of photosynthesis of plants in a greenhouse is to increase the concentration of CO2 . True – plenty of On a cold sunny day the best way to speed up growth is to warm the plants. True – plenty of light light and warmth CO2 is in short supply but chemical reactions are slow in the cold.False – it depends
