YEAR 5 Topic 1 Quiz 1

Which of the following is an inference?

• The ice is melting because it’s hot.

• The ice is 5 cm thick.

• The ice is cold to the touch.

• The ice is in a glass.

Identify the correct hypothesis using the given format.

• If the car is red, it will go faster.

• The higher the temperature (MV), the faster the sugar dissolves (RV).

• The type of sugar affects its solubility.

• Sugar dissolves in water.

Which is an example of a correctly identified MV and RV?

• MV = weight, RV = speed

• MV = parachute material, RV = air pressure

• MV = wind speed, RV = parachute size

• MV = height, RV = gravity

Which is a properly written hypothesis?

• If I add more salt, the soup will taste better.

• The heavier the ball (MV), the faster it falls (RV).

• Plants need sunlight to grow.

• If I water a plant, it will be healthy.

A student is testing how temperature affects the bouncing height of a rubber ball. What is the constant variable (CV)?

• Temperature of the ball

• Height of the bounce

• Type of ball

• Speed of the drop

In an experiment testing how the angle of a ramp affects how far a toy car travels, what is the responding variable (RV)?

• Type of toy car

• The angle of the ramp

• The distance the car travels

• The color of the car

Identify the manipulated variable (MV) in this hypothesis: 'The bigger the parachute, the slower it falls.'

• Parachute material

• Size of parachute

• Speed of the fall

• Height of the drop

What is a correct hypothesis format?

• The lower the temperature, the slower the reaction.

• The higher the pressure, the pressure increases.

• If I eat more, I will gain weight.

• Trees grow faster in the summer.

What is the inference in this situation? Observation: A puddle of water is under a drinking glass.

• The glass has condensation because of cold water inside.

• The glass is clear.

• The water is 20°C.

• The table is wet.

Identify the manipulated and responding variable: Experiment: How does caffeine affect heart rate?

• MV = Amount of caffeine, RV = Heart rate

• MV = Heart rate, RV = Amount of caffeine

• MV = Type of coffee, RV = Amount of caffeine

• MV = Type of person, RV = Type of coffee
