This collection of lessons is part of a larger unit focused on Matter and Energy in Organisms and Ecosystems. Students are introduced to photosynthesis through a phenomena, demonstrations and investigations. Students are provided opportunities to deepen understanding through five lessons culminating with the “Great CO2 Race” investigation and an engineering challenge. Several extensions and differentiated learning opportunities are also provided.
The lessons were developed for 70 minute classes.
Science - 7th grade
Math - 7th and 8th grade
Next Generation Science Standards (Science and Engineering)
MS-LS1-6: Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.
MS-LS1-7: Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.
MS-LS2-3: Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
MS-LS2-1: Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
MS-LS2-4: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
MS-ESS3-3: Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.
