We make observations using our senses. List the 5 senses.

Sight, Hearing, Taste, Touch, Smell

100

Name the 3 types of variables

Independent variable, dependent variable, controlled variable

Make one observation about this picture:

Any correct. e.g. a bird sits on the girl's head, the girl's mouth is open, etc.

200

The type of variable kept the same to ensure a fair test is:

a. Independent variable

b. Dependent variable

c. Controlled variable

d. Constant variable

c. Controlled variable

200

An educated guess about what will happen in an experiment is called:

a. Aim

b. Conclusion

c. Hypothesis

d. Title

c. Hypothesis

200

Name this type of graph and state one conclusion that can be made from it

Column graph

Any acceptable conclusion. e.g. Brown hair is the most common hair type, 9 students have black hair, red hair is least common, etc. 

200

What type of graph should be drawn from the below data?

a. Column

b. Line

c. Scatter plot

d. Pie graph

a. Column

300

The person stubbed his toe. Is an:

a. Observation

b. Inference

b. Inference

300

The variable you change on purpose is called the:

a. Independent variable

b. Dependent variable

c. Controlled variable

d. Changed variable

a. Independent variable

300

At the end of our experiment, we analyse our results and answer the question in the aim. This is called:

a. Hypothesis

b. Conclusion

c. Graph

d. Table

b. Conclusion

300

Identify the correct statement that can be made from the graph

a. 100 books were sold in week 7

b. More books were sold in week 6 than week 5

c. Twice as many books were sold in week 2 than week 1

d. Week 1 had the least book sales



c. Twice as many books were sold in week 2 than week 1

300

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

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. 

500

When we conduct an experiment we collect data. List the two ways we normally present this data. 

In a table and graph

500

Name this type of graph and the name of the line


Graph: Scatter plot

Line: Line of best fit

500

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
