Breathing

Breathing is taking in air (oxygen) and letting out air (carbon dioxide).

Gas Exchange

Gas exchange is when oxygen and carbon dioxide swap places in the lungs and body.

Lung Disease

Lung disease is when your lungs are sick and it's hard to breathe.

Nutrients

Nutrients are what your body needs from food to grow and stay healthy.

Food Tests

Food tests are how we find out what's in food.

Balanced Diets

Balanced diets have the right amounts of everything your body needs.

The Digestive System

The digestive system breaks down food so your body can use it.

Enzymes in Digestion

Enzymes in digestion help break down food faster.

Aerobic Respiration

Aerobic respiration is when your body uses oxygen to make energy.

Anaerobic Respiration

Anaerobic respiration is making energy without using oxygen.

Fermentation

Fermentation is when tiny things like yeast change food.

Photosynthesis

Photosynthesis is how plants make food using sunlight.

Leaves

Leaves are where plants make most of their food.

Transport in Plants

Transport in plants is how water and food move around inside the plant.

Plant Minerals

Plant minerals are special dirt stuff that plants need to grow.

Evolution

Evolution is how living things change over time.

Extinction

Extinction is when a type of animal or plant disappears forever.

Variation

Variation is when things are a little different from each other.

DNA

DNA is like the instructions inside every living thing.

Inheritance

Inheritance is how you get things from your parents.

Atoms

Atoms are tiny pieces that make up everything.

Elements

Elements are things made of only one kind of atom.

Compounds

Compounds are when you mix different kinds of atoms together.

The Periodic Table

The periodic table is a list of all the elements.

Metals

Metals are shiny and strong elements.

Non-Metals

Non-metals are elements that aren't shiny or strong.

Polymers

Polymers are long chains made of smaller bits.

Ceramics

Ceramics are hard things made from clay.

Composites

Composites are things made from mixing different stuff together.

Exothermic Reactions

Exothermic reactions are when things get hot.

Endothermic Reactions

Endothermic reactions are when things get cold.

Catalysts

Catalysts help make reactions go faster.

Combustion

Combustion is when things burn.

Thermal Decomposition

Thermal decomposition is when heat breaks something down.

Physical Changes

Physical changes are when something changes but stays the same stuff.

Chemical Changes

Chemical changes are when you make new stuff.

The Earth’s Atmosphere

The Earth’s atmosphere is the air around the Earth.

The Carbon Cycle

The carbon cycle is how carbon moves around the Earth.

The Greenhouse Effect

The greenhouse effect is when the Earth traps heat.

The Earth’s Resources

The Earth’s resources are things we get from the Earth.

Reduce, Reuse and Recycle

Reduce, reuse, and recycle means using less, using again, and making new stuff from old stuff.

Plastic Pollution

Plastic pollution is when there's too much plastic in the environment.

Extracting Metals

Extracting metals is getting metals out of rocks.

Forces

Forces are pushes and pulls.

Resultant Forces

Resultant forces are when you add up all the pushes and pulls.

Elasticity

Elasticity is how much something can stretch and go back to normal.

Extension of a Spring

Extension of a spring is how much a spring stretches when you pull it.

Pressure on a Solid

Pressure on a solid is how hard something is pushing on something else.

Pressure in a Fluid

Pressure in a fluid is how hard a liquid or gas is pushing.

Floating and Sinking

Floating and sinking is why some things stay on top of water and some go down.

Electromagnets

Electromagnets are magnets you can turn on and off with electricity.

Magnetic Fields

Magnetic fields are where magnets can pull or push things.

Elect

Elect

Gas Exchange Role in Breathing

Gas exchange is needed for breathing to work.

Asthma

Asthma is a lung problem that makes it hard to breathe.

Bronchitis

Bronchitis is when your breathing tubes get swollen and you cough a lot.

Pneumonia

Pneumonia is a lung infection that makes it hard to breathe.

Amylase

Amylase is a thing that breaks down carbs.

Protease

Protease is a thing that breaks down proteins.

Lipase

Lipase is a thing that breaks down fats.

Light Energy in Photosynthesis

Light energy helps plants make food.

Organic Substances in Fermentation

Organic substances are things that tiny creatures change.

Glucose

Glucose is a kind of sugar that gives you energy.

Chemical Structure of DNA

DNA is made of long strings of smaller parts

Substances in Chemical Changes

New stuff is made when things change chemically.

Recycling Materials

Recycling is making old stuff into new stuff.

Buoyancy Concept

Buoyancy is why things float.

Metals Characteristics

Metals are shiny, strong and can be bent.

Non-metals Characteristics

Non-metals are not shiny, strong, or easy to bend.

Subunits in Polymers

Polymers are made of smaller, repeating pieces

Chemical Elements Arrangement

Elements are put in
