In the first science unit, we will be learning about a variety of biotic elements that exist on Earth because of the light, heat, air, water and resources provided by the Earth and the Sun. 

Biotic elements are dependent on different interactions in order to survive.  Humans, like other biotic elements, rely on these interactions to survive. 

Humans also create and use technology to survive, and these technologies as well as other human actions, can have different impacts on the environment.

The purpose of the unit is to help us understand how to protect habitats and how the knowledge we possess can help us to improve food production and preservation techniques.
