The video tutorial demonstrates an experiment to measure water absorption by soil. It involves using a beaker, funnel, filter paper, soil samples, and a dropper. The process includes setting up the apparatus, pouring water onto the soil, and measuring the absorbed water. The experiment calculates the percentage of water absorbed by the soil and compares different soil types. It concludes that clay soil generally absorbs more water than sandy soil.

What materials are needed for the water absorption experiment?

• Beaker, test tube, filter paper, sand, dropper

• Beaker, funnel, filter paper, water samples, dropper

• Beaker, funnel, filter paper, soil samples, dropper

• Funnel, measuring tape, soil samples, dropper

What is the first step in setting up the experiment?

• Pour water into the beaker

• Measure 100 milliliters of water

• Fill the funnel with soil

• Fold the filter paper and place it in the funnel

How much water is initially measured for the experiment?

• 50 milliliters

• 100 milliliters

• 150 milliliters

• 200 milliliters

What is the purpose of pouring water over the soil until it drips?

• To clean the soil

• To measure the soil's water absorption capacity

• To make the soil muddy

• To test the water's purity

How is the percentage of water absorbed by the soil calculated?

• By adding the water absorbed to the soil weight

• By multiplying the water absorbed by the soil weight

• By subtracting the water left from the water used and dividing by the soil weight

• By dividing the water absorbed by the total water used and multiplying by 100

What conclusion can be drawn about clay soil compared to sandy soil?

• Clay soil absorbs less water than sandy soil

• Clay soil absorbs more water than sandy soil

• Clay soil and sandy soil absorb the same amount of water

• Sandy soil absorbs more water than clay soil

What is the significance of repeating the experiment with different soil samples?

• To test the purity of the water

• To see which soil is the most colorful

• To find out which soil absorbs the most and least water

• To determine which soil is the heaviest
