Hypothesis part 1
|
In idea for WHAT might happen. "I think that the brighter the light, the faster the plant will grow".
|
|
Hypothesis part 2
|
An idea for WHY something happens.
"I think this because........." Use science you have learnt in class or research. |
|
Method - step by step
|
Numbered steps, for example
1) Add 20ml water to a beaker 2) Heat water to 45 degrees centigrade 3) ...... Make sure people can follow it |
|
Method - do's and don'ts
|
Don't say - "get equipment.."
Don't say - "it" / "them" (name things) Don't say - "repeat it" say "repeat steps 3-5, 4 times) Do say WHY you chose the equipment you did. |
|
Method - numbers
|
How many repeats?
What are you changing? How many different values for the thing you change (e.g. 5 different levels of light) |
|
Collecting results
|
Use a table.
Make sure headings have full titles Make sure heading have units The first column should be what you are changing |
|
Processing data
|
Work out an average
Calculate (and plot) the range (highest and lowest) Can you work out the slope of a graph? Can you work out how much something changes? |
|
Plot a graph
|
Title
both axes labelled the same as table headings both axes have units line of best fit |
|
Managing risk
|
What are the dangers?
How dangerous it is? (High risk/low risk) How do you reduce risk? Does the risk change during the experiment? |
|
Trends and patterns
|
What is the obvious trend?
"As the amount of light increases, the plant growth rate increases". More information.... "This increase in growth is greatest to start with, when light levels are low" |
|
Comparison
|
Did other groups use the same method?
Did other groups use the same equipment? Would you expect different groups to get similar results? |
|
Evaluate - results
|
Are the results clear (and does this mean you think the experiment went well)?
Are the results reliable/are the ranges small (and does this make you think the experiment went well)? |
|
Evaluate - method
|
Was recording the results easy? Was it easy to be accurate? What was the hardest thing about measuring things?
Could you improve the method? Did you change the method and did that help? |
|
Do results support hypothesis?
|
Yes or no, but give examples to show this is true.
If the answer is no, why? Did you have the wrong idea? Was there a problem with the experiment design? |
|
Final question.
|
Use your references and say which reference you used.
Try to use science key words Add as much science as possible, but don't write too much, or guess |
|
References
|
What was the title of the book/web page?
When was it published? Who was it by? What was the information? |
