Photosynthesis Unit Science Biology Powerpoints Planning worksheets

Thus unit deals with Photosynthesis for year 6.

Plus other Science topics.

8 nice powerpoints plus planning plus worksheets.

Example planning :

To understand that green plants need light in order to grow well

To know that green plants make their own food using light in a process called ‘photosynthesis’

Sc1
To make careful observations of plant growth and explain these.

To make simple oral predictions PUT CHILDREN IN GROUPS
Begin lesson by showing ch. 2 plants; a green plant that has been kept in the dark for several weeks and a healthy plant. Give ch. time with talk partners to discuss the differences they observe and why these might be. Also ensure ch. can name all the parts and functions of the plant.

Lead these observations into a discussion about what plants need to be healthy. Take suggestions and write on board. Ensure ch. understand that plants need light, water, air, warmth and minerals.

Explain to ch. that plants need light the most of all the above to be able to grow well but seeds don’t need light to germinate. Why? Lead ch. into discussion about plants needing light to feed themselves and if they don’t get light they won’t grow just like if we don’t eat properly we won’t grow.

Ask ch. to talk to talk partners about how plants feed themselves. Introduce term on board ‘PHOTOSYNTHESIS’ Explain that ‘PHOTO’ means light and ‘SYNTHESIS’ means making something. Explain how photosynthesis works and demonstrate through ppt. (See below) Ensure ch. understand the leaves are vital for photosynthesis and then pass around some leaves so ch. can observe the detail.

Ask the ch. to make oral predictions about what would happen to the un-healthy plant at the beginning if it was left on the widow-sill for a few weeks. Ask the ch. what would happen to the healthy plants leaves if they were covered.

Plenary
Explain to ch. that we are now going to leave the un-healthy plant on window-sill and observe what happens over a period of the week. Take a photograph of it and allocate somebody the job of taking a photograph of it every day. At the end of the week, show photos on board as a slide show and ch. can write an explanation of what has happened. Discuss however that the plant will also need water, warmth and minerals. (Use a geranium plant as these perk up quickest when exposed to more light)

Ask ch. to discuss what minerals are. Explain that next lesson we will be discussing the need for good minerals to aid growth.
