This lab uses Wisconsin fast plant seeds to measure plant growth throughout the week. I love this lab to do while I teach graphing, as the data students collect will be graphed at the end of the week. However, you could also use this as an opener to photosynthesis, ecology or other lessons. Students love caring for their plants each day and it's a great way to teach students about the scientific method.
In this experiment, students will read background information about plants and photosynthesis. Then, they will plant Wisconsin fast plant seeds in tiny planters and cover one side with tin foil to prevent light from reaching the seeds. Over the course of a week they will water their plants each day, collecting data on plant height. After the lab is over, students graph their data and answer analysis questions.
