Question

How to make a model on soil profile?

Answer 1

You need :
1) Large and small plastic bottles.
2) Scissors
3) Funnel 
4) Gloves
5) Damp soil
6) Sand
7) Six worms
8) Rotting leaves
9) Black paper
10) Sticky tape
Step 1
Cut the top off the large, clear plastic bottle, as shown. Place the smaller bottle inside the larger one. Make sure the gap is evenly spaced all the way around the smaller bottle.
Step 2
Fill the gap with layers of soil and sand to the top. Press the soil down lightly. Gently place the worms on top of the soil, and cover them with rotting leaves.
Step 3
Cover the sides with black paper. Keep the soil moist. After a few days, remove the paper to see how the worms have tunneled away and dragged leaves into their burrows.
