Science
conservation of energy
Energy stores
There are various ways energy can be stored, some examples include:
Light
Heat
GPE
Kinetic
Chemical
Elastic
Sound
Nuclear
Energy transfers
Energy is constantly transferred from one place to another, types of energy transfer include:
waves (light and sound)
mechanical (through the use of force)
electrical work (batteries, moving energy via electric currents)
heating(transferring energy to an objects internal store via heating)

Atomic structure
subatomic particles
Subatomic particles are separate particles that make up an atom
there are 3 types:
- Protons
- Neutrons
- Electrons
Charge and mass
Different subatomic particles have different masses and charges, the overall charge of an atom is 0. The charges and masses of the subatomic particles are:
Protons: charge= +1 mass= 1
Neutrons: charge= 0 mass= 1
Electrons: charge= -1 mass= 0.005 or 1/2000

Cells
Cells are the building blocks of all types of life, from bacteria to humans
Prokaryotic cells
Prokaryotic cells are single cell organisms such as bacteria, viruses and microorganisms. they consist of cytoplasm, cell membrane and cell wall. They don't have a nucleus, but a single strand of DNA. They may also have extra strands of DNA called plasmids, for antibiotic resistance.
Eukaryotic cells
Plant cells are cells found in all plant life. they are made up of cell membrane, cell wall, cytoplasm, vacuole, chloroplasts and mitochondria. To respire, the plant uses chloroplasts to photosynthesise and gather energy.
Animal cells are cells found in all animals on earth. they consist of cytoplasm, cell membrane, nucleus, mitochondria, and ribosomes. Most of the time the mitochondria are used so the organism can breath aerobically.
