Asgard
This type of variable is manipulated or changed by the researcher to test its effects.
Independent Variable
A smaller subset chosen from a larger population to participate in a study
Sample (Sample amount, small portion of something)
Information and numbers you collect during an experiment
Data, values.
The final part of the scientific method where you state whether your guess was right or wrong based on your results
To find this number, you add up all your data points and divide by how many numbers there are
Average/mean
This type of variable is measured as the outcome or result of the experiment
Dependent Variable
This sampling technique gives every single member of the target population an equal and independent chance of being selected
Random Sampling
A study where you notice something about the topic/experiment to conduct a hypothesis
Observation/Observational study
This type of graph uses dots connected by a line to show how data changes over time
Line graph
You must always wear these over your eyes during science experiments to protect them from splashes
Goggles/safety glasses
These are factors kept constant throughout an experiment to ensure they do not unintentionally affect the results
Control Variables
This bias occurs when people choose to volunteer for a study, meaning they might share unique traits not found in the general public
Self selected sampling
A design that measures the dependent variable multiple times before and after the introduction of an intervention or treatment
Interrupted time series design
This metric unit is used to measure the mass or weight of small objects, like a paperclip
Gram or kg
You want to see if watering a plant with milk makes it grow. If you put one plant in a dark closet and the other on a sunny windowsill while testing this, your experiment isn't fair because you changed this extra thing..
Amt. of sunlight
A study conducted in a natural, real-world setting rather than a controlled laboratory
Field study
Using your five senses (sight, hearing, smell, taste, touch) to gather information
An observation
This type of chart looks like a sliced pizza and is used to show percentages out of a whole
Pie chart
A chemical tool with numbers on it used to measure the volume of a liquid in milliliters
Graduated cylinder
If something enters your eye, this is a tool used in a laboratory/chemistry classroom to wash it out.
Safety shower
This is the middle number in a set of data when you put them all in order from least to greatest
Median
Name the six steps of the scientific method
1. Ask a question
2. Do background research
3. Formulate a hypothesis
4. Test with an experiment
5. Analyze the data
6. Draw a conclusion and share results (Hyp. correct or wrong?)
You want to test if a brand-new video game improves hand-eye coordination. Instead of choosing kids randomly from the whole school, you only test the captain of the esports team. What sampling method is this?
Selective sampling
If you test whether the amount of fertilizer makes tomato plants grow taller, this is the factor you change on purpose/independent variable
Amt. of fertilizer
If you test whether the amount of fertilizer makes tomato plants grow taller, this is the factor you measure at the end/dependent variable
Height of tomato plants
