| A | B |
|---|
| scientific method step1 | observe and question natural world |
| scientific method step2 | form a hyothesis (educated guess) that answers your questions |
| scientific method step3 | design an experiment to the hypothesis |
| scientific method step4 | carry out experiment multiple times and collect data |
| scientific method step5 | Form conclusion from your data revise hypothesis |
| scientific method step6 | share results with other scientist |
| theory | concept tested many times by people |
| can a theory change | yes |
| hypothesis | to predict what will happen |
| why do scientists communicate their results to each other? | they compare results and improve the results |
| observation | information gathered by the 5 senses such as touch, smell, sight, taste and hearing |
| inference | explanation of observations |
| what lab safety precautions must always be followed? | Tie back long hair to keep away from chemicals, flames, or equipment |
| lab safety for chemical spills | wash spills with water immediately |
| lab safety to follow when dissecting animal | washing your hands after handling animals |
| why have a control experiment | to know that the data is reliable and valid |
| why run the experiment many times | to get the same results every time. |
| independent variable | the factor the scientist changes in an experiment |
| dependent variable | results the scientist measures. it is affected by the independent variable |
| controlled variable | factors that stays the same throughout the experiment "constant" |
