The Scientific Method is an organized way that helps scientists or anyone answer a question or begin to solve a problem. There are usually six parts to the scientific method: 1. Observation (What you See?). 2. Problem (What do you want to find out?). An example would be, “Does the color of a light bulb affect the growth of grass seeds?” 3. Hypothesis (I think ...because...). An example would be, “If I grow grass seeds under green light bulbs, then they will grow faster than plants growing under red light bulbs.” 4. Experiment (Materials and Procedures). In our example, you would set up grass seeds under a green light bulb and seeds under a red light and observe each for a couple of weeks. You would also set up grass seeds under regular white light so that you can compare it with the others. 5. Results (What happened?). Record data, the length of grass seeds. 6. Conclusion (I learned that ...). If the grass under the green light bulb grew faster, then you proved your hypothesis, if not, your hypothesis was wrong.
1.) Observations: Something you notice, measure, or detect. Make observations using your 5 senses. 2.) Inferences: Based on observations and prior knowledge. 3.) Qualitative Observations: Things you notice using you senses that can’t be measured. Observations using your 5 senses. 4.) Quantitative Observations: Measurable characteristics. Describe an item using numbers. Example: Observation: Clouds are white; Inference: Its day time
You observed the plant is extremely wilted, then you infer that is due to a lack of water. You observed that the card stopped running, then you infer that it stopped running because it was out of gas.
Qualitative: The things you notice using your senses that can't be measured. For example, you taste the candy is sour, you see that the flower is red, that the laptop is white, that she have three sisters, and that his hair is black; you touch the slug and is slimy. Quantitative: Describe an item using numbers: For example, using a ruler you can measure the bug to be 5 cm long, the fingernail to be 2cm long, that she is 150 cm tall; Using a scale you can find the mass of the beaker was 122g.
1.) Independent: The factor that the scientist changes on purpose. 2.) Dependent: The factor that changes as a result, often measured. 3.) Control Variable: The factor that is kept the same on purpose. Examples: Your cell phone bill depends on Minutes used in cell phone plan; How far you can drive depends on How fast you drive; Time it takes to drive somewhere depends on The amount of gas you have
