Which type of tape required the most force to lift?
Duct tape
What is the independant variable for this experiment?
Wing length (cm)
How many weeks and days did this experiment run for?

The method for an experiment should tell the reader how to change the _________, measure the ___________ and keep as many ___________ the same as possible: (fill in the blanks)
IV, DV, CV's
How much force did electrical tape require to lift?
1N
Which wing length resulted in the longest flight time?
4cm
Which type of graph would this data suit?
line

If the statement starts with "I think" it's probably a:
a. Hypothesis
b. Prediction
B!!
How many times more force is required to lift sticky tape compared to electrical tape?
3 times
Suggest a reason why the 12cm wings had the shortest flight time:
Too heavy
What do you expect the height of the plant to be on day 5?
2cm
How can you make experiments more accurate?
calibrate equipment and/or use better equipment
When drawing up a results table, the independent variable should always be on the (left or right)?
Left
What is the independent variable for this experiment?
Type of tape
What was the general trend from wing length of 4cm - 12cm?
decreasing flight time
Why was the height recorded at 0cm for days 0-2?
Bean seed hadn't sprouted yet
How can we make data from experiments more reliable?
do more trials
How do you calculate an average?
add the results from each trial together then divide by the number of results
