Grade 6 Science: Unit 2 | Energy, Experiments, and Earth Systems
Five original instructional days. This unit extends existing Unit 1 but is not a complete annual course. Read the explanation, discuss the example and then attempt independent practice.
Open companion practice workbook
Day 1: Energy models
Learn and read
A battery-powered fan converts stored chemical energy into electrical energy, motion, heat and sound. A model simplifies reality and should show important transfers and limits.
Worked example or interpretation
Draw an energy-flow chart with arrows; name both useful outputs and other transfers.
Guided explanation
Restate the main idea, explain why the model works, and complete the companion exercise independently.
Day 2: Controlled variables
Learn and read
A student tests whether ramp height changes how far a ball rolls on the same floor. Ramp height is altered while roll distance is measured.
Worked example or interpretation
Identify independent, dependent, and controlled variables; replicate safely.
Guided explanation
Restate the main idea, explain why the model works, and complete the companion exercise independently.
Day 3: Data interpretation
Learn and read
Invented trial distances are 18, 22, and 20 centimeters. These are classroom practice data, not observations from a real experiment.
Worked example or interpretation
Label graph axes, find mean and range, and do not overstate conclusions.
Guided explanation
Restate the main idea, explain why the model works, and complete the companion exercise independently.
Day 4: Water cycle
Learn and read
Water moves through evaporation, condensation, precipitation, runoff, infiltration and transpiration. Solar energy and gravity influence this cycle.
Worked example or interpretation
Draw a labeled diagram; a given droplet need not follow every stage in the same order.
Guided explanation
Restate the main idea, explain why the model works, and complete the companion exercise independently.
Day 5: Independent science check
Learn and read
A fictional watershed diagram includes a lake, sunny slopes, a stream and clouds. Use the description to analyze energy and water without inventing measured conditions.
Worked example or interpretation
Distinguish model inference from actual observation.
Guided explanation
Restate the main idea, explain why the model works, and complete the companion exercise independently.
