Many different types of science exist. And they are all named based on the subject matter they are studying.
Biology = the study of life
Earth Science = study of Earth and Space
Chemistry = the study of the composition and structure
Biochemistry = study of chemical composition of
Physics = study of the interactions between matter and
Look for the branches of science that start with each of the letter. Give the definition with illustration. Write a complete sentence on each. Branches of science Biology: the study of living things
Variables are factors in an experiment that can change.
Types of Variables
Independent Variables= Manipulated variables : are variables that change during an experiment.
(If you wanted to see what soap cleaned dishes the best, all the different soaps used would be independent variables.
Dependant variables=Responding variable: are the variables being measured.
I n a graph it is along the vertical axis or y-axis (So you would measure how clean the dishes are after using a specific soap. That result is dependant on the soap used to clean that dish.)
Controlled variables: are variables that never change over the course of an experiment. (Here it would be the amount of soap used to clean the dishes, you would always use the same amount.) They are kept the same.

Energy - needed for all of the traits of life. Without energy an organism could not survive. Food and Sunlight)
Water - Every living thing needs a constant supply of water. Our body is 70% water and our cells use water to carry out specials tasks like breaking down food. Plants need water to make their own food.
Oxygen - Living organisms use oxygen in order to release energy from food. We get Oxygen from the air what about fish, where does their Oxygen come from?
Minerals - Chemicals found in the water soil, and air and can not be made by living things, however living things need minerals to survive. (we get them from eating plants and animals, plants get them from the soil.)
Ex: Calcium and Potassium
Where does life come from? Section 1-3 H.W. pg. 21 ques.1-4
At first scientists believed that living thing things came from non living things.
This theory was called spontaneous generation.
Then in the mid 1800’s a man named Pasteur disproved this theory and it was replaced with a stronger theory called biogenesis , which states that all living things can only come from other living things.
