SCIENTIFIC METHOD

observeDraw what you see:

make a prediction

make a plan 1. Mix dirt rocks/pebbles on plate2. Form mountains along the edge of the plate3. Pack dirt firmly4. Use dropper of water to “rain” over your mountain range (record what happens)5. Use both droppers to add more rain (record what happens)

record the results With one dropper

With both droppers

draw a conclusion What were the effects of rain on the mountain range?

Where did erosion take place?

SCIENTIFIC METHOD

observeDraw what you see:

make a prediction

make a plan 1. Pack the dirt firmly to make a flat surface on your plate2. One student trace a river bed on the plate3. Hold your plate at a steep slope4. Pour water onto the riverbed5. Observe what happens to the river bed and banks.

record the results

draw a conclusion What happened to the river bed?

What happened to the river banks?
