front 1 Scientific Method | back 1 series of steps that help scientists solve a problem |
front 2 Steps of the Scientific Method (7) | back 2 1. Observe and State the Problem 2. Form a hypothesis 3. Test the hypothesis 4. Record and analyze data 5. Form a conclusion 6. Replication 7. Theory |
front 3 hypothesis | back 3 an tentative educated explanation for the observation or problem |
front 4 controlled experiment | back 4 2 part test that allows the scientist to specifically test the effects of a single factor, called the independent variable . (control setup vs. experimental setup) |
front 5 constants | back 5
|
front 6 independent variable | back 6 the factor being tested or manipulated during the experiment (The IF in the hypothesis) |
front 7 dependent variable | back 7 the change measured during the experiment direct result of the independent variable |
front 8 relationship between the independent variable and dependent variable | back 8 the dependent variable depends upon the independent variable ex. the growth of the plant (DV) is dependent on the amount of light (IV) it gets. |
front 9 quantitative data | back 9 information collected from an experiment that is numerical ex. The tree produced 75 apples. The mouse weighed 20 grams. |
front 10 qualitative data | back 10 information from an experiment that is descriptive ex. The flower is purple. The sand feels coarse. |

front 26 test tube | back 26 slender container that can hold small amounts of liquid |
front 27 erlenmeyer flask | back 27 container with wide base, cylindrical neck good for swirling, mixing and heating chemicals without spilling |
front 28 graduated cylinder | back 28 used to measure the volume of a liquid read at the meniscus |
front 29 petri dish | back 29 used to grow bacteria or hold small organisms |
front 30 pipet | back 30 used to transfer liquids |
front 31 medicine dropper | back 31 used to transfer small amounts of liquids (few drops) from one container to another |
