You will need: a container, a funnel, a measuring cylinder, cotton wool, dry soil, sand and water.
Collect some dry soil and sand. Using a weighing scale,
measure 50 g of soil and sand separately.
Take a funnel and plug it with moist cotton wool as shown. Place the funnel in a container. Fill 50 g of dry soil in the funnel. Use a measuring cylinder to measure 100 ml of water. Now, very slowly pour
water into the funnel.
Do not let the water overflow.
When the water stops dripping from the funnel, transfer
the water that has collected into the measuring cylinder and note the quantity.
1. Quantity of water that has dripped from the soil, (A) =__ml
2. Water retained in 50 g soil = 100 ml - A =___ ml.
Repeat the activity by taking 50 g of sand in the funnel. Note your observations.
3. Quantity of water that has dripped from the sand, (B) =____ ml.
4. Water retained in 50 g sand = 100 ml - B =____ ml.
What holds more water? Soil or Sand
