Variables
The variable that the scientist intentionally changes.
What is the Independent Variable?
This belongs on the top of every graph you make.
What is a TITLE?
This step answers the original question and states whether they hypothesis was correct/incorrect.
What is a CONCLUSION?
This is the basic unit for length in the metric system.
What is the meter?
The tool used to measure the length of an object.
What is a metric ruler or meterstick?
This is the axis that the dependent variable is found on.
What is the Y axis? (DRY MIX)
What is the name of the horizontal (side to side) axis?
What is X-AXIS?
An testable explanation/prediction for what might happen in an experiment.
What is a HYPOTHESIS?
This is the basic unit for volume.
What is the liter?
Explain how you measure the volume of a liquid using a graduated cylinder.
You must read it at eye level looking at the lowest point (meniscus).
The variable that you observe or measure during an experiment.
What is a DEPENDENT VARIABLE?
This type of graph is best used to analyze progressions, such as change over time.
What is a LINE GRAPH?
The step of the scientific method where you make graphs, look for patterns, and think about what happened.
What is the DATA ANALYSIS?
You are asked to measure the mass of a worm. What unit of measurement should you use?
Grams are used to measure mass.
A tool best used to measure the mass of an object.
What is a TRIPLE BEAM BALANCE?
Something that stays the same to keep an experiment fair.
What is a CONSTANT?
Ms. O is testing how different temperatures affect bacterial growth. She keeps all cultures in the same size petri dishes with equal amounts of light reaching the samples. This is the dependent variable.
What is number of bacteria?
Numbers, observations, or information you collect in an investigation.
What is Empirical Evidence/ Data?
A measure of how much 3D space an object takes up. This is measured in liters.
What is volume?
This is what it is called when you change from a base unit to another unit of measurement (example: meter to centimeter).
What is a CONVERSION?
I want to see if flowers bloom faster in sunlight or artificial light. I put 3 flowers in a room with 5 windows and I put 3 flowers in a room with 1 window and 5 artificial lights. What error have I made?
The Independent Variable (type of light) is not isolated so there are two variables. Only ONE variable can change at a time.
What can you conclude about heart rates of mice based on the data?
Mouse 1 min 3 min 5 min of exercise
1 91 99 104
2 87 92 99
3 92 97 102
As a mouse exercises for 5 min, its heartbeat rises over time.
I think that the amount of water you drink will affect your test score. Write a hypothesis for this.
If students drink more water, then their test scores will improve.
If students drink no water, then their test scores will decrease.
This is calculated using the formula: ? = mass (g)/volume (mL). It tells us matter is in a given space.
*Hint: You <3 this.
What is DENSITY?
A good tool to use to measure the volume of a box-shaped solid object.
What is a metric ruler?
