$100 Question Scientific Method What two words must be included in your hypothesis?

$100 Answer Scientific Method If and then

$200 Question Scientific Method What justifies your conclusion?

$200 Answer Scientific Method Data gathered from observations made during the experiment

$300 Question Scientific Method What are controlled variables?

$300 Answer Scientific Method Controlled variables are variables that kept the same for both the experimental and the control groups during an experiment

$400 Question Scientific Method What three things make up a good Experiment?

$400 Answer Scientific Method Having a control group Having only one independent variable Testing the hypothesis many times

$500 Question Scientific Method Name the steps of the scientific method in order

$500 Answer Scientific Method Ask a Question Form a Hypothesis Experiment (procedures) Collect Data Form a Conclusion Communicate your results

$100 Question Observations, Inferences, Predictions What is a Qualitative Observation? And give one example

$100 Answer Observations, Inferences, Predictions A qualitative observation is an observation that does not include numbers Example: The flower is yellow There is a bad odor coming from the milk The cake tastes salty It makes a hollow sound when tapped The owl making a hooting noise

$200 Question Observations, Inferences, Predictions What is a quantitative observation? Give an example?

$200 Answer Observations, Inferences, Predictions An observation that includes numbers Example: The was is 28 degrees There was 2.5 grams of sugar The house is 20 ft. tall

$300 Question Observations, Inferences, Predictions What is the difference between an inference and a prediction?

$300 Answer Observations, Inferences, Predictions Inferences use prior knowledge and observations to make a logical interpretation Predictions use prior knowledge to make a forecast of what will happen in the future

$400 Question Observations, Inferences, Predictions State whether the following sentence is an observation, an inference or a prediction based on the graph More girls ride in a car to school than boys

$400 Answer Observations, Inferences, Predictions

$500 Question Observations, Inferences, Predictions State whether the following sentence is an observation, an inference or a prediction based on the graph Students ride the bus because they live too far away to ride their bike or walk.

$500 Answer Observations, Inferences, Predictions

$100 Question Vocabulary Practice What is matter?

$100 Answer Vocabulary Practice Anything that has mass and takes up space

$200 Question Vocabulary Practice What is a theory?

$200 Answer Vocabulary Practice A well tested observation for many observations and experimental results

$300 Question Vocabulary Practice What is energy? And give an example of a type of energy

$300 Answer Vocabulary Practice Energy is the abiltiy to do work. The types of energies are chemical, electrical, heat, light, mechanical, and nuclear fusion

$400 Question Vocabulary Practice What is a law and give an example.

$400 Answer Vocabulary Practice A statement that describes what scientists expect to happen every time under a particular set of conditions without attempting to explain it. Example: Gravity. Newton’s 1st, 2nd, 3rd Law, etc.

$500 Question Vocabulary Practice What four vocabulary words represent the skills people need in order to think like a scientist?

$500 Answer Vocabulary Practice Predicting, Classifying, Observing, and Inferring

$100 Question Experimenting Name a hypothesis for the following problem: Will energy drinks increase the activity in mice?

$100 Answer Experimenting If mice are given energy drinks, then the mice will become more active

$200 Question Experimenting A student wants to see if energy drink increases the activity of mice. What would be a control group a student could use for this experiment?

$200 Answer Experimenting Observing the activity of mice that are not given any energy drink

$300 Question Experimenting What would be the independent and dependent variables in the experiment? A student wants to see if energy drink makes mice more active

$300 Answer Experimenting Independent: Giving mice energy drink Dependent: the activity of the mice

$400 Question Experimenting Why do you need controlled variables?

$400 Answer Experimenting Without controlling all other variables (keeping them the same for both the experimental and control groups), you would not be able to determine whether you results were because of the independent variable changing or not.

$500 Question Experimenting Name 4 controlled variables that you would have for the following experiment A student wants to see if energy drink makes mice more active

$500 Answer Experimenting Give the mice the same energy drink Give the mice the same amount of energy drink Use the same species of mouse Observe the mice for the same amount of time Observe the mice at the same time of day

$100 Question Let’s talk about Variables What is an independent Variable?

$100 Answer Let’s talk about Variables The variable that is changed in an experiment

$200 Question Let’s talk about Variables How does the dependent variable relate to the independent variable?

$200 Answer Let’s talk about Variables The dependent variable changes because of the independent variable changing

$300 Question Let’s talk about Variables Name a controlled variable for the following experiment A scientist wants to see if taking vitamins allows people to live longer. One group takes vitamins and the other group does not.

$300 Answer Let’s talk about Variables The people from the two groups are the same age Gender The people taking vitamins take the same brand The people taking vitamins take the same amount

$400 Question Let’s talk about Variables What is the independent and dependent variable for the following experiment: A scientist wants to see if taking vitamins allows people to live longer. One group takes vitamins and the other group does not.

$400 Answer Let’s talk about Variables Independent Variable: Taking vitamins Dependent Variable: Life expectancy

$500 Question Let’s talk about Variables Which is the control group and which is the experimental group? A scientist wants to see if taking vitamins allows people to live longer. One group takes vitamins and the other group does not.

$500 Answer Let’s talk about Variables The people taking vitamins are the Experimental Group The People not taking vitamins are the Control

Final Jeopardy What is the difference between a law and a Theory?

Final Jeopardy Answer A theory is a well tested explanation for many observations, while a law describes what happens for an observed pattern without attempting to explain it.
