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.
8th Grade Essential Questions and other relevant additions
The Amplify Science Grade 8 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.
Harnessing Human Energy
Essential Question: How can rescue workers get energy for their equipment during rescue missions?
Students help a team of rescue workers get energy to the batteries in their equipment. They ask questions, evaluate and analyze evidence and figure out how energy transfer works in a variety of systems.
Force and Motion
Essential Question: What happened in the missing seconds when the space pod should have docked with the space station?
Students figure out ideas about force, velocity, mass, and collisions as they explain why a spacecraft failed to dock as expected. They use the concept of cause and effect to construct explanations and make visual models showing what went wrong.
Force and Motion Engineering Internship
Essential Question: How can we design delivery pods that are damaged as little as possible when dropped?
Students design pods to be dropped to deliver emergency supplies. They explain why their designs are optimal using ideas about mass, velocity, collisions, and structure and function. They also define new engineering problems.
Magnetic Fields
Essential Question: Why did the tests of a magnetic spacecraft launcher not go as planned?
Students plan and conduct investigations to figure out why the test-launch of a magnetic spacecraft did not go as planned. They use patterns in magnetic field lines, and evidence from articles, models, and experiments to learn about magnetic force and energy.
Light Waves
Essential Question: Why is there a higher rate of skin cancer in Australia than in other parts of the world?
Students’ investigations of Australia’s high rate of skin cancer lead them to figure out how energy from different wavelengths of light can interact with matter. They write arguments based on evidence they gather from models, articles, experiments, and data.
Earth, Moon, and Sun
Essential Question: How can an astrophotographer plan for the best times to take photos of specific features on the Moon?
Students help an astrophotographer plan when to take pictures of specific moon features and a lunar eclipse. They use digital and physical models, and consider the ways they represent scale, to figure out what causes moon phases and eclipses.
Natural Selection
Essential Question: What caused the newt population in Oregon State Park to become more poisonous?
Students investigate what caused a population of newts to become so poisonous. They use mathematical thinking to make sense of patterns in data showing how traits of populations are changed by natural selection.
Natural Selection Engineering Internship
Essential Question: How can we design treatments for malaria that don’t lead to drug resistance?
Students use a digital model to test designs for a malaria treatment plan. They use their understanding of natural selection and patterns in populations to treat malaria while minimizing drug resistance, negative side effects, and cost.
Evolutionary History
Essential Question: Is this Mystery Fossil more closely related to wolves or to whales?
Students create arguments based on evidence about which living animals a mystery fossil is most closely related to. They figure out how evolution results in some body structures staying stable and others changing over millions of years.
