Grade 5 · Physical Science
Physical & Chemical Changes
Compare properties before and after physical changes and a safe simulated mixing investigation. Use multiple observations to decide whether the evidence is consistent with new substances forming.
55 min · ~12 min prep · 6 materials
Grade 1 · Physical Science
Light Helps Us See
Can you see a toy in the dark? Compare the same object with the light off and on. Then find things that make their own light.
35 min · ~6 min prep · 6 materials
Grade 1 · Physical Science
Sound & Vibrations: How Sounds Are Made
Tap, pluck, watch, and listen. Notice that vibrating materials move back and forth, can make sound, and can be moved by sound.
35 min · ~8 min prep · 9 materials
Grade 2 · Physical Science
Material Properties & Purposes
Test how familiar material samples handle water and bending. Then use the results to choose a material that fits a purpose.
42 min · ~10 min prep · 10 materials
Grade 2 · Physical Science
Solids & Liquids: How Matter Behaves
Move, pour, and compare familiar matter. Watch whether a sample keeps its shape or changes shape to fit a container.
40 min · ~8 min prep · 7 materials
Grade 3 · Physical Science
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.
45 min · ~8 min prep · 5 materials
Grade 3 · Physical Science
Magnetic Forces
Use observations and simple data to explain magnetic pushes and pulls across a gap. Compare pole orientation, distance, and specific tested objects.
45 min · ~10 min prep · 6 materials
Grade 4 · Physical Science
Electricity & Simple Circuits
Build and test simple circuits, use a bulb as evidence of a complete path, and investigate which tested materials can bridge a gap.
52 min · ~12 min prep · 9 materials
Grade 4 · Physical Science
Light Reflection & Vision
Build a source → object → eye model to explain vision, then use a mirror target investigation to show that changing mirror orientation changes the direction of reflected light.
45 min · ~10 min prep · 6 materials
Grade 4 · Physical Science
Waves & Sound
Build and revise qualitative wave models to compare amplitude and wavelength, use physical evidence to reason about wave-caused motion, and explain one limit of a model for sound.
50 min · ~8 min prep · 5 materials
Grade 5 · Physical Science
Conservation of Matter
Measure the same complete setup before and after matter changes form or mixes, then use the data to explain what stayed the same and why a scale reading can change when matter leaves what is being measured.
52 min · ~12 min prep · 8 materials
Grade 6 · Physical Science
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.
55 min · ~10 min prep · 4 materials
Grade 6 · Physical Science
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.
55 min · ~12 min prep · 8 materials
Grade 6 · Life Science
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.
