Photosynthesis
On Thursday I worked with the grade 2 and 3 students (4 classes) at Findon PS to introduce them to the concept of Photosynthesis.
We started out addressing the needs (input) of a plant: sunlight, nutrients, carbon dioxide, water etc.We then discussed what a plant produces (output): flowers, leaves, fruit, oxygen etc. The students demnstrated a good understanding of this, although they did get confused between the role of gases (carbon dioxide and oxygen). The students worked in teams to produce a diagram of these processes.
One student dressed up as the sun and the other students dressed up as trees. They acted out the lifecycle of a plant: waiting as a seed until the sun came along and gave them energy (tapped them on the shoulder). The trees grew slowly, putting out branches and leaves until they were fully grown, blowing in the breeze.
The classes then watched the Photosynthesis Song (YouTube video) and acted this out as trees.
The students really enjoyed the lesson, especially dressing up. One student commented "I think that was the best lesson this year... I love it when Andrew does fun things with us - and we learnt so much about Photosythesis".
