Scientific Inquiry, Variables, & Types of Observations
| Question | Answer |
|---|---|
| What you are trying to find out from your experiment | question |
| an educated guess or prediction of what will happen during the experiment | hypothesis |
| a plan to test your prediction;your procedure, step-by-step | experiment |
| collecting information and data from the experiment | investigating |
| recording information you gather with your senses during the experiment | observe |
| looking at all the data and variables of the experiment | analyze |
| the results of your experiment; the answer to your question | conclusion |
| observations that include numbers or measurements | quantitative |
| observations that describe something useing only the 5 senses | qualitative |
| any factor that can change in an experiment | variable |
| the one variable that the scientist changes; it is what you are testing | independent |
| the variable that you will measure or observe | dependent |
| The group in an experiment that remains unchanged so that you have something to compare your results to | control group |
| the variables in an experiment that COULD change but remain the SAME since you only test one thing at a time | constants |
| In an experiment to see if heating water makes sugar dissolve faster, the temperature of the water would be the | independent variable |
| In an experiment to see if drinking lemon water everyday helps you lose weight, your weight would be the | dependent variable |
| In an experiment to see if electric cars are more sluggish than gas powered cars, the driver for both cars would be a | constant variable |
| In the Mythbusters experiment to see if greenhouse gasses really do contribute to global warming, the same sized ice sculptures would be a | constant variable |
| In the Acid Rain lab, the type of beans used in each group would be a | constant variable |
| In the Acid Rain lab, the different vinegar solutions would be the | independent variable |
| In an experiment to see which paper towels can hold the most liquid without breaking, the time it takes for the paper towel to break would be the | dependent variable |
| The desk is smooth is an example of a | qualitative observation |
| The seed is 4 cm long is and example of a | quantitative observation |
| The cookie smelled like chocolate is an example of a | qualitative observation |
| The average speed of the cheetah was 80mph is an example of a | quantitative observation |
| The mass of the cheeto is 3 grams is an example of a | quantitative observation |
| A good hypothesis explains the relationships between the | variables |
| This should be worded in an "If......, then......" statement | hypothesis |
| In the Acid Rain lab, the group of seeds with H2O was the | control group |
| In an experiment to see if a new drug prevents sneezing in people who are allergic to grass, the new drug is the | independent variable |
| In an experiment to see if you increase the temperature of water, the faster a boiled egg will cook, the time it takes for the egg to cook is the | dependent variable |
