Name 3 features this graph is missing
Any 3:
Title
Labels
Units
Scale
400
Make one observation and one inference about the picture.
Any correct, e.g:
Observation: Plants are growing over the escalator
Inference: The building is abandoned
400
Name the variable that we measure of observe
Dependent variable
400
"To investigate the effect of wing length on the distance a paper plane flys"
This is a:
a. Hypothesis
b. Conclusion
c. Observation
d. Aim

400
Use the graph below to identify the independent and dependent variables in the experiment:
Independent variable: Time (hr)
Dependent variable: Distance (Km)
400
Give an appropriate title for the below graph
Must contain independent and dependent variables. E.g. effect of car colour on number of cars sold or number of cars sold by car colour
500
Explain the difference between an observation and an inference.
Observations are pieces of information that we get directly from our senses.
Inferences are ideas that we come up with to explain our observations.
500
Tim conducted an experiment to investigate if the car shape affects the speed it can travel. Identify the independent variable, dependent variable and two controlled variables for this experiment.
Independent variable: car shape
Dependent variable: speed
Controlled: any two appropriate. E.g. same car colour, same distance car travels, same mass of car, etc.

When we conduct an experiment we collect data. List the two ways we normally present this data.
In a table and graph

Graph: Scatter plot
Line: Line of best fit

State the type of graph you would draw for the below data and identify the variable you would place on the x-axis (horizontal) and the y-axis (vertical).
Type of Graph: Line
X axis: Length of pendulum
Y axis: Time taken to complete 1 swing
