What happens to the brightness of bulbs in a series circuit when more bulbs are added?
They become dimmer
What part of the plant absorbs water from the soil?
Roots
What happens to a series circuit if one bulb blows?
The whole circuit stops working
What do we call a rock that has changed due to heat and pressure?
Metamorphic
What star is at the centre of our solar system?
The sun
What property of metals makes them useful for electrical wiring?
They are good conductors of electricity
Name 2 parts of a leaf's structure

A plant is placed in a cupboard for two weeks. What will most likely happen to it?
It will become weak/yellow and may die because it cannot photosynthesise
What are the two main products made during photosynthesis?

Explain why parallel circuits are commonly used in homes instead of series circuits.
Appliances can work independently, and one failing does not stop the others working
Name the three main types of rocks and explain briefly how each forms.
Igneous - Cooled magma/lava - Intense heat
Sedimentary - Compacted sediments - time and pressure
Metamorphic - heat, time and pressure
What scientist developed the theory of gravity after observing a falling apple?

Some rocks deep underground melt, rise to the surface as lava, cool, and later get broken into sediments. What major Earth process is this describing?
The rock cycle
