Making the most of Photosynthesis How do farmers maximise the growth of their plants? Starter: Farming Rags to Riches. How could this farmer …………………………Get to this point?

Success criteria I can name techniques famers use to grow crops. I can explain how some farming methods work. How do farmers maximise the growth of their plants?

Photosynthesis: word equation activity How do farmers maximise the growth of their plants?

I can name techniques famers use to grow crops. I can explain how some farming methods work. Greenhouse demo Set up half a plastic bottle with some damp mud on the inside. Shine a bright lamp on it and leave it over the lesson. Set up a similar pot of mud with no lamp. Explain what is seen How do farmers maximise the growth of their plants?

Call my bluff – your go! Choose a word from the hat. Find the definition. Rewrite it if you like. Come up with 2 other definitions. How do farmers maximise the growth of their plants?

Hydroponics Transect Polytunnel quadrat Tubers Nitrate ions How do farmers maximise the growth of their plants?

Hydroponics – think pair share. http://www.youtube.com/watch?v=W5tnHfikb64 Hydroponics grows plants without any soil. What are the problems and positives of this? Grit free salad. No nutrients, have to supply chemicals. How do farmers maximise the growth of their plants?

I can name techniques famers use to grow crops. I can explain how some farming methods work. Hydroponics Mineral supply is controlled so minerals recycled. This is cheaper and causes less pollution Better control of disease No grit in salad! Tall plants need support How do farmers maximise the growth of their plants?

Cress heads How do farmers maximise the growth of their plants?

Task – use pages 154 – 155, and the information to help you design a farm. You are about to buy a new farm and you need to fill in a profile for the farm, to give to the bank for a mortgage application. You will need 1) a birds eye view diagram of your farm, what will you grow where? 2) A business plan – what will you grow and why? Include in your business plan ….. What techniques will you use to grow your plants? Organic / intensive / green houses / hydroponics. You are a CROP farm but will you have any animals and why? What will be your biggest earner? Will you buy /rent machinery? Etc There are no limitations to what you can grow. Use your computer token to find out the profits on your plant choices. I can name techniques famers use to grow crops. I can explain how some farming methods work.
