Scientific Method
What is the first step in the scientific method?
Ask a question/make an observation
Any factor that can change in an experiment
What is A Variable
This tool measures temperature.
What is the Thermometer
This type of graph shows change over time.
What is a Line Graph
An educated guess based on research and observations
What is a Hypothesis
The step that comes after forming a hypothesis.
Design and conduct the experiment
The part of the experiment that does NOT have the independent variables/test variables applied
What is the Control Group
This tool is used to measure volume in milliliters
What is a Graduated Cylinder
This table allows you to see information in an organized manor so you can properly analyze results.
What is a Date Table
Data collected using the body's senses to help form an educated guess.
What is an observation
Why is it important to repeat experiments?
Increase reliability and allow for REPLICATION.
It is purposefully changed to see if it has an effect on what is being tested/measured
What is the Independent Variable
This tool is used to measure mass.
What is the triple beam balance
Easily, visually compare categories of data and their values.
Data that uses words to describe what is observed in an experiment.
What is qualitative data.
A summary of findings in an experiment that states whether the hypothesis was supported or not.
What is the Conclusion
The measured results of what is being tested.
What is Dependent Variable
This tool is used to magnify small objects and organisms.
What is the microscope.
What is Correlation.
Data that uses statistical features like mean, median, and range
What is Quantitative Data
Describe a full experiment using all steps of the scientific method.
1. Make an observation/ask a question
2. Research.
3. Form your hypothesis
4. design and conduct the experiment
5. Collect the data
6. Analyze the data
7. Draw a conclusion
Explain how to identify variables in an experiment.
The independent variable is what you can manipulate or change in the experiment and the dependent variable is what you measure based off of the effect of the independent variable. The controlled variable stays the same the entire experiment.
Name 3 science tools and explain their uses.
Spring Scale
Graduated Cylinder
Triple Beam Balance
Microscope
Thermometer
Hot Plate
A student is conducting an experiment to see if the temperature gets hotter as the time of day goes by. They use a data table to collect and write down the temperature every hour from sun up to sun down. What kind of graph would they need to use to analyze their data?
What is a Line Graph
A logical explanation of an observation based on prior knowledge or experience.
What is an Inference
