Using the Scientific Method

Put the steps of the scientific method in the correct order in the column on the left. Match the example with each of the steps in the right column Steps of the Scientific Method Observation Hypothesis Experiment Data Conclusion Example Ms. Jones noticed that a lake was completely green from algae blooms (excessive growth). Ms. Jones thinks the algae are thriving off nitrogen fertilizer running off from nearby farms. Ms. Jones uses unique plants to absorb extra nitrogen to see if it prevents the nitrogen runoff. She counts the algae growth in the lake and finds that the algae growth has declined. Her research shows that the unique plants likely absorbed the algae and can prevent blooms. Turtles lay eggs in holes that they dig in the ground. The temperature that eggs are incubated at determines whether the offspring are male or female. Warmer temperatures lead to more females. The normal soil temperature is 35C.Use the data table to identify the constant, control group, experimental group, IV, and DV. Constant pH of water Sand color Wind speed Control Group Eggs incubated at 35 C Experimental Group Eggs incubated at 25, 30, 40, and 45 C Independent variable Temperature Dependent variable Number of females Match the characteristic of life with the description. Homeostasis The ability of an organism to maintain stable internal conditions. Cellular organization All living things are made of cells. Cells are the smallest unit of life. Responsiveness Organisms react to their environment. Metabolism All of the chemical reactions that make and use energy in an organism Reproduction Organisms make more of their own kind from one generation to the next Heredity Parents pass traits down to their offspring through DNA Growth and Development Organisms get bigger and change as they grow I notice that when I walk into the room, my parrot squawks. I think that he might squawk because he recognizes me. I test this by walking into the room and having my mom, brother, and father walk in the room at different times and record the number of squawks. We all wore the same color clothing, took the same number of steps into the room, spent the same amount of time in the room, and did not wear any perfumes. I found that my parrot only squawks when my mom and I walk into the room. These data suggest that my parrot squawks when he sees females. The control group is me.The experimental group is the rest of my family.The IV is the person walking into the roomand will be graphed on the x-axis.The DV is the number of squawksand will be graphed on the y-axis.The constants are the color of clothing, the number of steps into the room, the time spent in the room, and the lack of perfume.
