Scientific Method
Scientific Method Steps and Experimental Info!
| Term | Definition |
|---|---|
| Observation | Made using the 5 senses. ex. the plant is green, the plant's leaves are 5 cm across |
| Inference | A guess based on the senses. ex. It is hot outside, therefore people must want ice cream |
| Problem | ALWAYS A QUESTION! ex. What happens to my pulse rate if I exercise? |
| Hypothesis | Best guess about what would happen. ALWAYS A SENTENCE. ex. If I exercise, then my pulse rate will increase |
| Experiment | Only change one variable at a time, do multiple trials, take an average |
| Independent Variable | What I CHANGE/MANIPULATE ex. temperature, amount of light |
| Dependent Variable | What I MEASURE ex. how tall plant grows, how large leaves are |
| Controlled Variable | Used for BASELINE/COMPARISON. ex. If I want to know exercise impacts my pulse rate, my CONTROL would be my resting pulse rate. |
| Constants | Any factors kept the same throughout the experiment. |
| x-axis | Where Independent Variable goes |
| y-axis | Where Dependent Variable goes |
| CER | claim, evidence, reasoning. Conclusion to your experiment |
| Direct Relationship (graph) | As one variable increases, the other variable also increases |
| Indirect Relationship (graph) | As one variable increases, the other variable decreases |
| Theory | Big Idea that explains why or how something happens. Backed up by tons of evidence! |
| Order of steps of scientific theory | Observation, Problem, Hypothesis, Experiment, Data, Conclusion, Theory |
| What does the acronym TACKLE stand for | T-title, A-axis, C-connect, K-key, L-labels, E-even scale |
