Saving Energy at Home

🧪Lab Brief #5

Conservation.

🎯 Your mission

Run the experiment. Find out what really happens.

⚡ The twist

Nature loves to surprise the careful watcher.

🤯

Mind = Blown

🔬 The more you look, the more nature shows you.

🔮

Make a hypothesis first

Before you start: write down what you think will happen, and why.

Safety First

Read rating labels only — never open an appliance or a fuse box.

Steps

Step 1 — Read

Read the explanation above and note the two key terms before you start.

Step 2 — Do

List every appliance in one room with its power rating and estimated daily hours. Rank them by weekly energy use and compare your ranking with what you assumed before you started.

Step 3 — Observe

Record what actually happened, including anything that did not match what you expected.

Step 4 — Record

Write a conclusion that answers the question this lesson opened with, and state your uncertainty.
