Groundwater and Aquifers

🧪Lab Brief #1

Earth Systems.

🎯 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

Groundwater fills spaces between rocks and soil underground. Aquifers are underground layers of rock that hold and transmit water. Many communities depend on wells that tap into aquifers.

Key Words

Tap a word to see its definition.

Materials Needed

sand
clay
water

Safety First

Wash your hands thoroughly afterwards and keep the material away from your face.
Mop up spills straight away so nobody slips, and keep liquids away from sockets.
Check glassware for chips before use and carry it with both hands.

Steps

Step 1 — Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 — Do

Investigate soil layers: fill a jar with soil and water, shake it, and let it settle overnight. Identify the layers of clay, silt, sand, and organic matter.

Step 3 — Observe

Watch carefully for any changes and note the time.

Step 4 — Record

Create a data table to organize your measurements.
