Units
Unit 1
Cells: Life's Building Blocks
Practices evidence that living things are made of cells, the parts of plant and animal cells and their jobs, and how the cell works as a system.
Learning standard: 7.L1U1.8 · all living things are made of cells, and the parts of a cell
Unit 2
Body Systems
How the nervous and endocrine (hormone) systems send messages, how the excretory system removes waste, and the basic organs of the reproductive system, all at a simple organ-and-job level.
Learning standard: 7.L1U1.10 · how cells, tissues and organ systems keep animals alive
Unit 3
Our Senses
Practices natural sensory systems: sight, hearing, smell, taste and touch. It follows the Grade 6 science skill descriptors on natural and technical sensory systems in the New Brunswick curriculum.
Learning standard: 7.L1U1.11 · how organisms sense and respond to keep their bodies stable
Unit 4
How Plants Work
The parts of seed plants and what they do, photosynthesis, gas exchange, transpiration and pollination, and how plant structures suit where a plant grows.
Learning standard: 7.L2U1.12 · how plant cells turn light energy into food energy
Unit 5
Motion, Forces & Newton’s Laws
Practices speed, velocity, acceleration, forces, friction, gravity and Newton's three Laws of Motion, with stability. It follows the Grade 8 science skill descriptors on motion and stability and the Laws of Motion in the New Brunswick curriculum.
Learning standard: 7.P3U1.4; 7.P3U1.3 · Newton's laws of motion
Unit 6
Electromagnets & Generators
Practices the link between electricity and magnetism: how an electromagnet works, what makes it stronger, the devices that use them and how generators make electric current.
Learning standard: 7.P2U1.1 · electromagnetic forces, and what makes them stronger or weaker
Unit 7
Earth's Moving Surface
Practices plate tectonics and evidence from fossils, rocks and continent shapes, the rock cycle, and how processes at different speeds shape Earth's surface, including the Cascade volcanoes.
Learning standard: 7.E1U1.6; 7.E1U1.5 · evidence of moving plates in rocks, fossils and continents, and the cycling of matter on Earth
Unit 8
Weather and the Water Cycle
How the Sun, air, water and land interact to cause daily weather, the water cycle, tools for measuring weather, and why long-term forecasting is hard.
Learning standard: 7.E1U2.7; 7.E1U1.5 · how air, water and land interact in weather, and how forecasts are made
