Characteristics of Living Things

Living things all share a few common characteristics. Living things are made of cells, contain similar chemicals, use energy, respond to their surroundings, grow and develop, and reproduce. All organisms need water food, living space , and stable internal conditions. Homostasis is the process by which an organism's internal environment is kept stable ins pite of changes in external environment.

A (The) Scientific Method

Every science class that you will ever take will begin by refreshing or reteaching "THE" scientific method. But, I like to think of it as "A" scientific method.

Everyone of us uses our five senses to investigate the world around us. We are all naturally investigative scientist. These are a few of the skills to be a true scientist. Other skills such as inferring and predicting are equally important. Scientific attitudes play an important part in all investigations as well, to include, curiosity, honesty, open-mindedness, skeptiscism and creativity.

The steps of "A" scientific method-
1. Make an observation,
2. Ask a question,
3. Form a hypothesis,
4. Conduct an experiment,
5. Collect data - accept or reject hypothesis.
