Crop+farming

9C On the farm

Crop farming
Recall how glucose is used by plants. Describe ways in which farmers can grow better crops. Recall where some of the different products made from glucose can be found.

 * Starter **
 * Review homework and completed work from last lesson
 * Key term quiz - there are lots of key terms in this unit
 * Discuss what parts of plants we eat and what else we use them for. Now watch the video below and see some examples of plant parts that we eat

> > > > a. (optional) before you test leaves for starch assess the risks involved in the experiment using the > b. follow the to help you completing your test > >
 * Activities **
 * 1) Complete [[file:ES9_CHAP_Cc10.pdf|farming our food]] to summarise your learning about plant parts
 * 1) Read and discuss p36 of Exploring Science 9
 * 1) Complete [[file:ES9_Cc036_07msu.doc|uses of glucose]] to summarise how the main product of photosynthesis is used by plants.
 * 1) You are given two plants (or trays of leaves). Test a leaf from each tray to find out which plant has been in the sun and which kept in the dark. You will be testing the leaves for starch content because that is the molecule that plants use to store the glucose made by photosynthesis.
 * 1) Complete Q1-6 from p36-7 of Exploring Science 9
 * 1) Extension: Find out about modern methods of farming such as the use of plastic tunnels? Read and answer the questions on [[file:ES9_CHAP_Cc12.pdf|Growing lettuce]]
