Evidence for a Changing Climate

🧪Lab Brief #4

Evidence for a Changing Climate.

🎯 Your mission

Set it up. Test it. Be amazed.

⚡ The twist

The slowest changes are the biggest ones.

🤯

Mind = Blown

🪨 Every grain of sand on every beach used to be a mountain.

🔮

Make a hypothesis first

Predict: which will erode faster?

What You'll Learn

No single measurement carries the case. Surface temperature records, ocean heat content, retreating glaciers, sea level rise and shifting species ranges are independent lines of evidence, and they agree — which is what makes the conclusion hard to escape.

Safety First

Have an adult check your set-up before you start, and tidy everything away afterwards.

Steps

Step 1 — Read

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

Step 2 — Do

Plot four independent climate data sets on a shared timeline and mark where they agree. Write one sentence on why four agreeing records are stronger than one long one.

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.

Where you see this in real life

Today's weather, tomorrow's beach, next century's coastline — all this.
