What is the correct thing to do if a glass beaker breaks in the science laboratory?

• Pick it up in your hands and put the broken glass in the rubbish bin

• Walk to get the dustpan and broom, sweep up the glass and empty into broken glass bin

• Sweep it into the water troughs

• Scream, laugh and run to get the teacher

• A jug

• A measuring cylinder

• A beaker

The apparatus (equipment) for filtering water, is:

• Conical flask, filter paper, funnel

• Funnel, beaker, heat mat, filter paper

• Filter paper, Bunsen burner, test tube and test tube holder

• Retort stand, boss head and clamp, test tube, filter paper

Which person (eye) is reading the volume of water, correctly:

• A

Below are some pictures of a Bunsen burner on another flame: Which of the following statements describes the heating flame?

• Blue, easy to see, high temperature, collar is closed

• Yellow, difficult to see, medium temperature, collar is open

• Blue, difficult to see, high temperature, collar is open

As part of a scientific report you write your goal or what you want to achieve during the practical. This is known as the:

• aim

• hypothesis

• results

• conclusion

A primary investigation that you have done in class was to boil water and measure its temperature over time. What is the best conclusion for this experiment?

• The longer the water is heated over the Bunsen burner, the higher its temperature, until it boils.

• Does water take ten minutes to boil?

• The temperature of the water decreases over time.

• Water boils at different temperatures because the thermometers have inbuilt errors.

The independent variable in an experiment is:

• The one that you change on purpose

• The ones that you keep the same

• The one that you measure

• The ones that aren’t kept the same

In an experiment Fiona gives different amounts of water to her plants to find out if the different amounts affect how high they grow over two weeks. To make sure her experiment is valid, she should have:

• Different amounts of sunlight

• Different amounts of fertiliser

• The same amount of water

• The same size pots and plants, the same soil and temperature

What is the name of this piece of equipment?

• tripod

• beaker

• test tube

• measuring cylinder
