Take 1-2 min to think about some of the most important lab safety procedures Be ready to share!

Safe Science - In the Classroom Pay attention No sleeping No talking

Do Now: BIology On the back of “Science is…CONPTT” notes, describe in 2 sentences what you think classifies something as “science”. (You should be silently writing and in your assigned seats)

Biology jobs are divided into categories in our database which include Agriculture, Anatomy / Physiology, Bioinformatics / Biotechnology, Botany, Cell Biology, Conservation, Ecology, Environmental Science Jobs, Genetics, Marine Science, Medicine, Natural Resources, Pharmacology, Postdoctoral ( postdoc ), Toxicology, Veterinary Medicine, and Zoology .

What is science? Objectives: (1) Differentiate between phenomena that are scientific and things that are not. (2) Explain the criteria for categorizing phenomena as science (Consistent, Observable, Natural, Predictable, Testable, and Tentative). (3) Distinguish between scientific observations and scientific inferences. (4) Make scientific inferences from scientific observations. Essential Question: How can you tell the difference between science and non-science using scientific observations and inferences?

As we go through the Powerpoint, you must fill out your notes You will use these notes to complete a worksheet Everything you complete in this class will be graded during binder checks!!! There WILL be an exit ticket at the end of class

Scientific knowledge is NOT a collection of TRUTHS Scientific knowledge is NOT a collection of TRUTHS. There are no universal, absolute, and unchangeable truths in science. Scientific explanations must be changed when data provide insurmountable difficulties for the existing knowledge. Not all explanations are equally valid; some are "better" than others, simply because they work better, explain more observations.

COnptt

C stands for Consistent Consistent: it will occur over and over in the same exact setting. If you run an experiment, you want to make sure the setting is the same every time so you get the same results. EX: A green plant will always grow towards a light source.

O stands for Observable Observable: Something that is able to be sensed by either sight, hearing, smell, touch or taste (though we don’t taste things in science). EX: I saw that plant eat a fly.

N stands for Natural An element in the world that is not caused by human activity. EX: Green plants convert sunlight into energy.

P stands for Predictable Specific predictions can be used to foretell an event. Each prediction can be tested to determine if the prediction is true or false. Ex: Without sunlight (or artificial light), green plants will die.

T stands for testable Can we use an experiment to test the ideas of the subject? If so, then it may be a science. Ex: Life comes from life, and not non-living things.

T stands for Tentativeness Scientific theories are changeable and correctable, even to the point of the theory being proven wrong. Scientific theories have been modified and will continue to be modified, meaning they are tentative. Ex: The number of human chromosomes was once "known" to be 48, but is now considered to be 46.

How are you going to remember conptt? Activity: With a person sitting next to you, create a mnemonic statement to help you remember CONPTT Ie, Please Excuse My Dear Aunt Sally (mnemonic for PEMDAS) **Be ready to share out! At least 3 groups will share their mnemonic statement. We will vote on the best!**

(false) PSEUDOSCIENCE Non-science portrayed as a legitimate science EXAMPLES: astrology, lunar effect, etc.

March of the Penguins Write down as many observations as you can on the back of your notes

What is an Observation? An observation is the process of using one of your five senses in order to gain information. Your five sense are sight, hearing, touch, smell, and taste **Never use taste in science.**

What is Inference? Inference is a conclusion reached on the basis of evidence and reasoning. An inference is NOT a hypothesis.

Look back at your video observations… - Did you make observations or inferences? - Label them

Science vs. non-science Activity Green plants will grow towards a light source. Walking under a ladder will cause bad luck. Some plants eat meat. Extraterrestrial beings have visited Earth. Green plants convert sunlight into energy. With a rod, Moses parted the sea so his people could cross to the other side. Without sunlight (or comparable artificial light), green plants will die.

Choose 2 of the following statements Complete the graphic organizer in your notes: 1. The Bermuda Triangle causes ships and planes to sink and disappear. 2. Life comes from life and cannot come from non-life. 3. The number of human chromosomes was once "known" to be 48, but is now considered to be 46. 4. Living things were once grouped into 2 major groups, then 3, then 4, and now 5, because the criteria used for classifying living things have changed. 5. We know that the world began about 6000 years ago, and nothing will change that. 6. At one time, it was thought the heart pumped blood out of a large container as an "open system", but now it is known that blood "circulates" in a closed system.

Exit Ticket Behavior Expectations - No talking, no electronics - Raise your hand if you have a question - Flip paper over and put pencil down when finished - You have 10minutes

Exit 1. List the six (6) components that classify something as being scientific.   2. How can you tell the difference between Science and Non-Science? (3-4 complete & thought out sentences)
