Students will be able to correctly demonstrate the processes of photosynthesis by performing a lab with 90% to 100% accuracy.
The photosynthesis lab should reflect an understanding of how plants are autotrophic organisms and the processes they use to produce their own energy.
1) Importance of photosynthesis
2) Plants are autotrophic organisms
3) Plants require energy from the sun and CO2 to make chemical energy
4) Photosynthesis cycle
In groups of two, you will be designing a lab that demonstrates the ability of plants to photosynthesis. Each group will be given five pots, birdseeds, potting soil, water and two dark sheets and one light sheet of paper. To begin, you will plant birdseed in each of the five pots. Once planted, one pot will be place in complete darkness, one in complete light, one covered with light colored paper, one covered with dark colored paper and the last one will be covered with dark colored paper with holes in it. Five days after the planting, your group will measure the length, in centimeters, of each plant in the different light conditions. Next, you will record lengths and color of all five pots. You will then use this data to make a conclusion from your results.
