  1. Earth Boot Camp 4.7A Examine properties of soils, including color and texture, capacity to retain water, and ability to support the growth of plants

  2. #12 STAAR 2013, RC3; Supporting; 5.2D 1. A student conducts an investigation using four identical bottles, each with a hole in the bottom. The student fills each can with a different type of soil and then adds 200 milliliters (ML) out of water to each bottle. The beakers below show the amount of water that drains through the soil and out the bottom of each can. A B C DSome plants have roots that reach very deep underground. Which type of soil will most likely stop water from flowing to the deepest roots of these plants?

  4. 2002 TAKS Information Booklet, #12 2. Three soil samples were tested to see how much water each could hold. The same amount of water was added to each funnel of soil. Very few plants would probably grow in the clay because the water would —A fail to reach the roots of the plantsB become too cloudyC run through the soil too quicklyD become poisonous to the plants

  6. 3. A student wants to find out which type of soil holds the most water. He uses four identical pots with holes in the bottom. He fills each pot with a different type of soil and waters the pots with the same amount of water. How can he find out how much water stays in the soil in each pot?A By planting seeds and measuring plant growth in each potB By measuring the amount of water that drains from each potC By observing which soil looks wettest after the water has been added to the potsD By feeling the soil before and after adding water to each pot 2003—#3 (73%)

  26. 12. Top soil has a rough texture with spaces between the grains. This allows water to filter quickly through the soil. Clay soil, however, is composed of smoother particles that stick together with little or no spaces between. What would happen if clay were used as a water filtration method? The water –Awould flow freely through the clay.B would not flow easily through the clay.C in the clay would evaporate very quickly.D would change the clay into sedimentary rock.
