Physical Science · Structure of Matter
Density: Mass, Volume & Floating
Measure mass and volume, calculate density, compare objects with water, and use force evidence to explain why objects sink, float, or approach neutral buoyancy.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Earth Science · Water in Earth's Systems
The Water Cycle: Driven by Sunlight and Gravity
Build and revise a multi-pathway model of water moving among ocean, land, living things, and atmosphere; distinguish solar-powered phase changes from gravity-driven flows.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Cells and Organization
Cell Structure & Function
Use microscope observations and cell models to explain how cell structures support the jobs a cell must do, then compare evidence from plant and animal cells.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Cells & Organization
Human Body Systems: Cells to Organ Systems
Use organization models and prepared data to explain how cells form tissues and organs and how human body subsystems interact.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Ecosystem Dynamics
Ecosystem Interactions & Resource Availability
Analyze aligned organism, resource, and population records while keeping explanations calibrated to the evidence.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Structure of Matter
Atoms, Elements & Molecules
Build and interpret particle models for simple molecules, distinguish elements and compounds using atom identity, compare discrete molecules with an extended structure, and identify what the models do not show literally.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Chemical Reactions
Chemical Reactions: Evidence & Conservation
Analyze before-and-after property data to decide whether a chemical reaction occurred, then use particle models to explain atom conservation.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Forces & Motion
Forces & Newton's Third Law
Model equal-and-opposite interaction forces and apply Newton's Third Law to improve a one-dimensional collision solution.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Forces & Motion
Force, Mass & Change in Motion
Plan fair one-dimensional investigations and use evidence to explain how net force and mass affect changes in motion.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Earth Science · Weather & Climate
Weather Forecasting: Air Masses, Pressure & Fronts
Collect and interpret weather data to explain how moving air masses and fronts change local conditions and support probabilistic forecasts.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Earth Science · Weather & Climate
Ocean Currents: How Oceans Shape Regional Climate
Use long-term coastal climate evidence and ocean-circulation models to explain how ocean currents can redistribute thermal energy—and why currents are not the sole cause of climate.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Matter & Energy in Living Things
Inside Cells: Food Molecules & Usable Energy
Use a cell-level particle model to explain how organisms rearrange food matter and transfer energy for life processes without creating atoms or energy.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Energy Transfer
Thermal Energy Transfer: Temperature, Mass & Materials
Plan fair thermal-energy investigations, analyze temperature-change data, and use particle models to explain patterns involving mass and material type.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Waves
Waves: Amplitude, Frequency, Reflection & Absorption
Measure repeating waves, analyze amplitude-energy data, and model reflection, absorption, and transmission at material boundaries.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Earth Science · Dynamic Earth
Plate Tectonics: A Changing Earth
Use maps and models to connect plate motion with earthquakes, volcanoes, mountain building, and pathways through the rock cycle.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Heredity & Variation
DNA, Genes & Chromosomes: How Traits Are Inherited
Model how genes are organized on chromosomes, compare sexual and asexual inheritance, and explain conceptually how mutations can alter proteins and affect traits.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Energy
Kinetic & Potential Energy: Mass, Speed & Position
Use graphs to analyze how object-scale kinetic energy relates to mass and speed, then model how relative position changes gravitational potential energy in an Earth-object system.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Evolution & Variation
Natural Selection: Why Some Traits Become More Common
Investigate how inherited variation can affect the chance of surviving and reproducing in a particular environment, using fictional population evidence rather than an individual choosing to change.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Ecosystems & Interdependence
Ecosystem Relationships: Competition, Predation & Mutualism
Compare evidence from woodland, tide-pool and desert examples to identify and predict recurring ecological interaction patterns across different ecosystems.
