Science in Middle School is designed to spiral, which helps students explore connections across the four domains of science and engineering every single year: Physical Science, Life Science, Earth and Space Science, and Engineering Design. Students use the science and engineering practices that actual scientists and engineers use as they investigate the natural world and design and build systems respectively. Students are learning actively through inquiry.
Each science unit has an overarching essential question that is particularly relevant and appropriate to the age group. These questions are meant to inspire wonder and by the end of the unit, provide opportunities for students to practice solving problems.
7th Grade Essential Questions and other relevant additions
Three-dimensional learning in the Amplify Science Middle School 7th Grade Course. The Amplify Science Grade 7 Integrated Science Course includes nine units that support students in meeting the NGSS. The following unit summaries demonstrate how students engage in three dimensional learning to solve real world questions and problems.
Geology on Mars
Essential Question: How can we search for evidence that other planets were once habitable?
Students make scientific arguments about whether flowing water or flowing lava formed a channel on Mars. They use models to figure out how systems (such as the atmosphere and geosphere) interact on Earth and other planets.
Plate Motion
Essential Question: Why are fossils of Mesosaurus separated by thousands of kilometers of ocean when the species once lived all together?
Students figure out how fossils of one kind of animal came to be separated by an ocean due to tectonic plate motion over millions of years. To solve the mystery, students obtain information from articles, videos, and models, and they analyze patterns in maps. Plate Motion Engineering Internship: Students use knowledge of plate motion to design and test a tsunami alert system for the Indian Ocean. They use mathematical thinking as they analyze patterns in the results of their testing.
Rock Transformations
Essential Question: Why are rock samples from the Great Plains and from the Rocky mountains composed of such similar minerals, when they look so different and come from different areas?
Students write explanations and make visual models showing why rock formations in the Great Plains and Rocky Mountains are made of very similar minerals. They figure out how energy flowing through Earth’s systems transforms rock material.
Phase Change
Essential Question: Why did the methane lake on Titan disappear?
Students develop and use models to figure out if a lake on Titan, a moon of Saturn, froze or evaporated. They explain how energy transfer and attraction between molecules affect molecular motion at a small scale and phase change at a large scale. Phase Change Engineering Internship: Students analyze data as they design devices that use phase change materials to keep babies warm. They obtain information from articles and hands-on investigations about how energy transfers as matter melts or freezes.
Chemical Reactions
Essential Question: Why is there a mysterious reddish-brown substance in the tap water of Westfield?
Students figure out how changes at the atomic scale caused a large-scale problem in a town’s water supply. They ask questions, use models, and read articles to learn about properties of substances, atoms and molecules, and chemical reactions.
Populations and Resources
Essential Question: What caused the size of the moon jelly population in Glacier Sea to increase?
Students figure out why a population of jellies in an ecosystem is increasing dramatically. They plan and conduct investigations to figure out how stability and change in populations of animals is affected by resource availability.
Matter and Energy in Ecosystems
Essential Question: Why did the biodome ecosystem collapse?
Students construct explanations for why a fictional biodome ecosystem collapsed. They figure out cause-and-effect relationships in ecosystems related to the cycling of carbon atoms during photosynthesis and cellular respiration.
