Life Science · Life Cycles
Animal & Plant Life Cycles
Build and compare life-cycle models to explain how organisms begin life, grow and change, reproduce, and eventually die while offspring begin a new generation.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Forces & Motion
Balanced & Unbalanced Forces
Investigate how pushes and pulls in different directions affect an object's motion. Change one force condition at a time and use what the object does as evidence.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Forces and Interactions
Magnetic Forces
Use observations and simple data to explain magnetic pushes and pulls across a gap. Compare pole orientation, distance, and specific tested objects.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Forces & Motion
Patterns of Motion & Prediction
Observe repeated motion, identify a pattern, test a prediction, and revise when conditions change.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Traits
Inherited Traits & Variation
Use plant and animal data to find inherited-trait patterns, variation among similar organisms, and evidence that environmental conditions can influence how traits develop.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Survival & Environment
Adaptations & Survival in Habitats
Use repeated camouflage data and organism-needs evidence to build a calibrated habitat-survival argument.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Animal Behavior
Why Animals Live in Groups
Analyze repeated observations and build an argument about how some animal groups can help members survive.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Animal Diversity
Animal Classification: Vertebrates & Invertebrates
Use body-structure evidence to classify animals as vertebrates or invertebrates and then compare familiar groups such as mammals, birds, insects, arachnids, mollusks, and crustaceans.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Forces and Interactions
Static Electricity: Forces Without Touching
Investigate how charged objects can attract or repel across a gap and use distance evidence to describe cause-and-effect patterns in static electric interactions.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Forces and Design
Bridge Engineering: Designing for a Load
Build, test, and improve small bridge prototypes while controlling span, materials, and load placement so failure points become useful engineering evidence.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Life Science · Ecosystems and Survival
Changing Habitats: When a Need Is Missing
Use organism-and-resource evidence to explain why the same habitat change can help some organisms, challenge others, and make survival impossible for others.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Earth Science · Earth's Past
Fossils & Past Environments
Organize fossil data, find distribution patterns, and use evidence to infer broad features of past environments.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Earth Science · Weather & Climate
Weather vs. Climate: Finding Patterns in Data
Read tables, pictographs, and bar graphs to find seasonal weather patterns. Then use long-term information to compare climates in two regions.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Forces & Motion
Friction Experiment: Which Surface Slows Motion?
Run a fair sliding test on different surfaces, measure how far an object travels, and use the results to explain how friction can change motion.
Interactive Activity · Worksheet · Investigation · Teacher Slides
Physical Science · Science Practices
Scientific Method: Ask, Test, Measure & Explain
Turn a question into a fair test, change one variable, collect repeated data, and use evidence to explain what the results support.
