dierent? Do they smell dierent?
Teacher's Note
Ask for oral answers, no written answers.
3. Spread a teaspoonful on the white paper and look at each -in
what ways do they look dierent?
Teacher's Note
Ask learners for oral answers. Make sure you get answers from
dierent learners and it is not just the same learners each time.
4. Then put your soil samples into the glass jars. Pour in water to
make the jar almost full, cover the top and shake each jar to
mix the soil and water.

below. In each jar, the water has let the large grains settle at
the bottom, the very small grains are on top, and the clay
grains are so small they are still mixed with the water. You
may see some plant parts floating on the water.
