What name is given to something that can perform all the basic life processes?
A living organism
Which animal group has feathers?
Birds
What is a microorganism?
A living organism that is too small to be seen without a microscope.
Which circuit component provides electrical energy?
A cell or battery
Which component produces light in a circuit?
A bulb/lamp
Name three things that organisms need to survive.
Any three: food, water, oxygen and shelter
What is the main difference between vertebrates and invertebrates?
Vertebrates have a backbone; invertebrates do not.
Name three types of microorganisms.
Bacteria, viruses and fungi
Which component is used to open or close a circuit?
A switch
Which component produces sound in a circuit?
A buzzer
What life process means changing position or place?
Movement
To which vertebrate group does a snake belong?
Reptiles
Which plant group produces cones and usually keeps its leaves throughout the year?
Coniferous trees
What is a complete circuit?
A circuit with an unbroken path through which electric current can flow.
What usually happens to a bulb’s brightness when another cell is added correctly to a series circuit?
It becomes brighter.
What life process removes waste products from an organism?
Excretion
A creature has no backbone, has legs and has eight legs. What type of animal is it?
A spider/arachnid
Give one helpful use of microorganisms.
Examples: making bread, yoghurt or cheese; decomposition; producing medicine.
What happens to a bulb when the switch in its circuit is opened?
The bulb switches off because the circuit is incomplete.
Two identical circuits contain one buzzer each. One circuit has one cell and the other has two cells. Which buzzer will usually be louder?
The buzzer connected to two cells
A dormant seed does not appear to move or grow. Explain why it is still classified as living.
It can perform life processes when the conditions are suitable, including growth and reproduction.
A new animal has a backbone, moist skin and can live both in water and on land. To which group should it belong? Explain.
Amphibians, because they have moist skin and can live in water and on land.
Explain how the same type of microorganism can be helpful in one situation but harmful in another.
Some microorganisms are useful in food production, medicine or decomposition, while others can cause disease or spoil food.
A circuit contains a battery, wires and a bulb, but the bulb does not light. Give two possible reasons.
Examples: a wire is disconnected, the switch is open, the bulb is broken, or the battery has no charge.
Two cells are added to a circuit, but the bulb still does not light. Explain why adding cells cannot fix every circuit problem.
Current still cannot flow if the circuit is incomplete or a component is incorrectly connected or broken.
