Think about ALL the variables that can affect the system.
Choose your INDEPENDENT VARIABLE: (:iv)
Choose your DEPENDENT VARIABLE: (:dv)
List your CONTROLLED VARIABLES:
(;cv)
Choose a title:
(;title)
The Research Question should talk about the variables. It has been written for you
To achieve a good level you should describe the problem in more detail:
(;problemdescription)
You are going to increase the (.iv). What do you think will happen to the (.dv)? (:dvhyp)
Using science explain why you think this will happen?
(;hypsci)
Can you justify your hypothesis (or give any more details).
(;hypdetail)
Your Independent variable is (.iv). How are you going to change it:?
(;ivvar)
Your Dependent variable is (.dv). How are you going to measure it:?
(;dvvar)
Your Controlled variables are (.cv)
How are you going to control each of them?
| (,cv) | (;cvvar) |
What is the lowest value of (.iv) you will test? (:botrange)

How strong is the correlation of your data? (:correlation) How many anomalous points are there? (:numanom)
Which ones are they?How did the method work? (:methsuc) What is your reasoning? (:evalreason) What are the problems {issues} with the method? (;issues).
You took readings from (.botrange) to (.toprange) with (.range) datapoints.

Instead of (.repeats) repeats how many repeats would you do next time? (:newrepeats)
How would you solve the issues you identified
| (,issues) | (;solutions) |
What elso could you investigate to learn more about the topic (:fur)
(.name)
How does the (.iv) affect the (.dv). Keeping (.cv) constant.
(.problemdescription)
I predict that as the (.iv) increases the (.dv) will (.dvhyp).
I think this will happen because:(.hypsci)

Independent Variable: (.iv)

Dependent Variable: (.dv)
(.dvvar)
Controlled Variables(s)
| Variable | How it's controlled |

(,equip)
My data is a (.relationship) which goes (.updown).
That tells me that as the (.iv) increases the (.dv) goes (.updown).
I think this relationship is because (.discuss)
I predicted that as the (.iv) increased the (.dv) would (.hyp)
(.conclusion)
My data show a (.correlation) correlation.
There are (.numanom) anomalous points.
(.anoms)
I felt the method worked (.methsuc) because (.evalreason) The problems with the method are (,issues).

(.fur)
This is the variable YOU will change.
It goes along the bottom of the graph
This is the variable YOU will measure.
It goes along the left hand side of the graph
These are the variables that will need to be kept constant to make it a fair test
] (botrange)[This is the lowest value of (.iv) you will test?
Include units
What is the highest value of (.iv) you will test?
Include units
Write your First name and Surname
] (title)[The title can be just a statement of what you will study.
It could be just: "The relationship between (.iv) and (.dv)" with a explaination of the situation.
Decribe some examples of how knowing the relationship between (.iv) and (.dv) could be useful
] (dvhyp)[Write a simple statement e.g. increases linearly, goes down slowly
] (hypsci)[Use scientific terminology to explain why you think your prediction is correct
] (hypdetail)[Can you explain the science words you have used
] (ivvar)[You have choosen to change the (.iv) you need to measure it to make sure you have the right values. How will you do that?
] (dvvar)[You wnat to know how the (.dv) is affected by the (.iv) so you need to measure it. How will you do that?
] (datapoints)[Datapoints means how many different measurements of the (.iv) you will make.
] (repeats)[Repeats is how many times you will repeat the whole experiment
Repeating an experiment allows you to take an average {which can be more accurate} and spot any mistakes {anomalies}
The relationship can be a straight line {linear} or a curve
] (updown)[Does the line {or curve} go up, down or stay straight
] (discuss)[As (.iv) increases the (.dv) goes (.updown). You need to explain WHY that happens using scientific reasoning
] (pre)[Your prediction is what you think will happen, will the (.dv) go up or down when you increase the (.iv)?
] (correlation)[A strong correlation is when all the data is on {or very close to} the line of best fit {trendline}
A medium correlation is when the points are quite near the line {but not very}
A weak correlation is when its hard to know where to draw the line of best fit
No correlation is when the data is all over the place and not in a line
An anomaly is a datapoint that is much further from the line than most of the others
It might have been because of a mistake when you took the measurement
To descibe an anomaly you can write the value of the (.iv) at which it occured
] (methsuc)[Based on your experience performing the experiment did it work well
] (evalreason)[Try to give specific reasons why you think the experiment went well or badly
] (issues)[Problems or isssues are reasons that the results might not be as good as you expected
Also write down things that you can do better next time
It is always possible to improve an experiment by increasing the range of the IV.
State what your increased range would be.
For a good level you can explain how to improve the range of data {see Examples}
It is always possible to improve an experiment by increasing the number of repeats
Be realistic assuming you have another whole lessons to do the experiment again
Solutions should specifically explain what method or equipment you can use to solve the identified problems
] (improvements)[You can improve the method or the equpment to get better results.
Give specific details about each one.
You investigated how the (.iv) affects the (.dv). Is there anything related to that you could test in a whole new experient?
] (cvvar)[For each controlled variable state how you will make sure its controlled.
Often this can be done by using the same materials, location or values. State what those values are!
] (equip)[
List the equipment you will use to measure the values. With details like how long a ruler you will use
] (instructions)[Step 1 is often "set up the equipment as shown"
You can use phrases like "repeat step n five times"
The diagram should show the setup of the equipment.
It should be labeled
You can take a photo or draw a picture. A screenshot
cmd+shift+4can be used] (tablesrc)[
Your table MUST inlude (.iv) and (.dv).
It should have a row for each value of (.iv) and a column for each repeat
Your Graph should plot IV along the bottom and DV up the side
it should have the points plotted as a scatter plot
it should be clear and neatly presented
it should have a line of best fit {trendline}
A good way to do this is to list the risks and the measures you will take to minimize them.
