Adaptation:
This is when any organism (eg. a plant, animal or any other living thing) makes changes to their shape to ‘adapt’ to living in a certain place or ‘environment’. For example, some plants might adapt to living next to the windy seasides by growing extra strong roots to keep them firmly in the ground without being blown away during stormy weather. Some animals, such as Polar Bears living in the Artic, when most of their food supply is completely frozen over during the winter, have learned to adapt by eating as much as they can during the summer months and getting really fat (and fat is a store of energy), so they can survive when there is not so much food available for them. Can you think of any ways that we humans have adapted to our environments to help us survive better?

Agriculture:
Agriculture is the science of growing healthy plants and animals for our own uses, such as food, clothing, and many other products we rely on – can you think of any animal products and plant products that we use, which is not just for food?

Agriculturist:
This is someone that works in agriculture, such as a farmer or rancher. They are experts in producing products to use and sell from animals and plants.

Algae:
Algae (spoken like ‘al-gee’) are tiny and very simple plant-like organisms (see organisms), which are found in water or on wet surfaces, in very big numbers. In fact very often the numbers of Algae in one place is so big that together they can make massive areas of sea water look green and slimy. There is sometimes so much Algea in one place that even some of the mightiest Whales in the ocean can eat enough to fill their enormous bellies and not eat anything else besides.

Atmosphere:
The atmosphere is the name given to the first layer of gases that wrap around the whole world and keep us safe from the coldness and vacuum (a place where no air or any other gases exist) of space. Planet Earth’s ‘atmosphere’, inside which we all live, has many gases in all different amounts, which mixes to form the ‘air’ that we breathe – so there must be enough of what type of gas for us all to breathe?

Atom:
One of the tiniest particles that we know about and millions and millions of atoms together in many different ways, makes everything around you – even your own body! You could think of atoms together making bigger things, just like a many many bricks used to build a great big tower.
