Chapter 1 What Is Life Science

Can you believe Mr. Dorchak use to be afraid of

Life Science?

It’s not my fault! It’s scary and hard!

Mom, please don’t make me learn Life

Science…

Standards

5. Structure and Function in Living SystemsThe anatomy and physiology of plants and animals illustrate the complementary nature of structure and function.

6. Physical Principles in Living Systems (Physical Sciences)Physical principles underlie biological structures and functions

Investigation and Experimentation 7. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will:

c. Communicate the logical connection among hypotheses, science concepts, tests conducted, data collected, and conclusions drawn from the scientific evidence.

d. Construct scale models, maps, and appropriately labeled diagrams to communicate scientific knowledge (e.g., motion of Earth's plates and cell structure).

Section 1 Thinking Like A Scientist- Science is a way of learning about the natural world.- Scientists use skills such as observing, inferring, predicting, classifying, and making models to learn more about the world and make scientific progress- Observing means using one or more of your senses to gather information- Your senses include sight, hearing, touch, taste, and smell. Observations can be either quantitative or qualitative.

I wish I didn’t have to observe

your hair looking like that,

- Quantitative observations deal with a number, or amount

ex.)Seeing that you have eight new e-mails in your inbox is a quantitative observation.- Qualitative observations deal with descriptions that cannot be expressed in numbers

ex) Noticing that a bike is blue and that a grape tastes sour are qualitative observations.

5

-When you explain or interpret the things you observe, you are inferring, or making an inference - Making an inference doesn’t mean guessing wildly = based on reasoning from what you already know.- Predicting means making a forecast of what will happen in the future based on past experience or evidence- Inferences are attempts to explain what is happening or has happened, predictions are forecasts, or what will happen in the future.
