A student puts different types of soil into 2 pots and pours the same amount of water into the pots. How can she find out how much water stays in each type of soil?
A By weighin each pot
B By looking at the pot
C Measuring amount of water that drained from pot
D Plant seed in pots
I'm not 100% sure, but my guess would be C.
Answer this by the process of elimination. What will you find if the weight of each pot is the same? nothing. If different, then there is more soil in one pot than the other one. By looking at the pot? Looking may give you a close answer but it isn't very scientific. Draining water from the pot will tell you how much water is held up by the soil. Planting seeds in the pot will grow plants. Now, which of these answers is what you want?
You are correct! The correct answer is C - measuring the amount of water that drained from each pot.
By process of elimination, we can determine that option A, weighing each pot, would not give us the information we need about how much water stays in each type of soil. The weight of the pot alone does not tell us how much water is retained by the soil.
Option B, looking at the pot, may give us a rough estimate but it is not a precise or scientific method of measurement. It is difficult to visually determine how much water is retained by the soil accurately.
Option D, planting seeds in the pots, would allow us to observe the growth of plants but it does not directly give us information about how much water is retained by the soil.
Therefore, option C, measuring the amount of water that drained from each pot, is the most appropriate and scientific method to determine how much water is held by each type of soil. By measuring the amount of water that drains from the pots after watering, we can calculate the water retention capacity of each type of soil.
