My class and I are learning about plants in our science unit we’re doing right now. We learned a lot. I am with a group of three girls, including me. Our scientific question for this experiment is: What is the effect of having less soil on plant growth? Our hypothesis is: If we put less soil in the cells, then the plant won’t grow as high everyday because the plant doesn’t have enough soil. Our controlled quad is normal. We are manipulating the soil.
We have two quads. One quad is controlled and one quad is manipulated. Controlled means that everything is the same. Manipulated is where we change one thing in the process. We have four cells in each quad. Everytime we water the cells, we took note of what was happening. For our Controlled quad, the tallest plant is 2 centimeters tall. The color of the plant is green. Our Manipulated quad’s plants are 3 centimeters taller. What we changed in our Manipulated quad was the amount of soil. It turned out to be taller than I thought.
