CYCLE 3 BIOLOGY BOOTCAMP

In this lesson we will cover the following topics: Theory vs Law, Properties of Water, Cellular Respiration and Photosynthesis

Mrs. Palavra (Mrs. P)

1. We are using a writing utensil and laptops. No other materials needed.

2. Stay on task and engage.

3. Respect the ideas and space of others.

4. Go with the flow and don't work ahead.

5. When I count us down from 5, that means I need your full attention!

Let's Begin!

Scientific Theory vs Scientific Law

As you watch the video, take notes on the essential question.

Essential Question: How are scientific theories and laws different?

​

Theory vs Law

• Statements or DESCRIPTIONS of WHAT we expect to happen, based on many observations and data collected.

• Only stat WHAT happens. NO attempt to explain why.

Scientific Law

• Broad EXPLANATIONS as to WHY something happens in the natural world

• support by many lines of evidence

• may be modified or changed with new evidence (always changing)

• theories NEVER become laws

Scientific Theory

Scientific Theory vs Scientific Law

• Both are widely accepted by the scientific community.

• Both are based on tested hypotheses.

• Both are supported by large amounts of data and evidence.

• Both could be shown to be wrong at some time if there are new data to suggest so.

How are theories and laws similar?

Match

Match the following statements as a scientific theory, scientific law, theory and law, or hypothesis. Discuss with your shoulder partner.

• Scientific Theory

• Scientific Law

• Hypothesis

• Scientific Theory & Law

Provides an explanation of cells and what we know about them.

Describes what nature does under certain conditions and will predict what will happen.

Something that can be tested

Are widely accepted by the scientific community

• Provides an explanation of cells and what we know about them.

• Describes what nature does under certain conditions and will predict what will happen.

• Something that can be tested

• Are widely accepted by the scientific community

Rapid Review

Do you have what it takes to answer each question correctly in 30 seconds?

1. Use your notes

2. Use those test taking strategies: Reread the question, process of elimination, find key terms, etc.

3. Try your best!

Multiple Choice

Tamar is talking about evolution with a friend. The friend says, “It’s just a theory, so I don’t believe it. When they prove it and it becomes the law of evolution, then maybe I’ll change my mind.” Which of these possible replies best describes scientific principles or the work of scientists?

• Scientific theories do not become scientific laws; they are explanations for natural phenomena based on evidence.

• Science always finds the right answer; the answers that scientists and researchers discover never change.

• He should be wary of science because it is based on research and evidence, not bias and opinion.

• Scientists take each other at their word regarding experimental results, and the public should, too

Multiple Choice

Which of the following are well supported descriptions about what happens in nature, without attempting to explain why it happens?

• Scientific law

• Scientific Theory

• Both a scientific law and theory

• Scientific Observations

Multiple Choice

In the winter months in colder climates the top layer of lakes will freeze over. Why does ice stay at the top of a lake instead of sinking to the bottom?

• Ice is colder than liquid water and therefore condenses.

• The water molecules in the ice expand and create more space between them. This causes ice to be less dense than liquid water.

• The water molecules in the ice move closer together and create less space between them. This causes ice to be less dense than liquid wate

• Ice is warmer than liquid water and therefore expands

Multiple Choice

A florist places a bouquet of white carnations in water containing blue dye. After time, the flowers turn blue. What process helped the carnations to change color

• Water’s ability to form crystals

• Ability of water to dissolve salt

• Cohesion and adhesion of water molecules

• Water prohibits the flower from freezing

Multiple Choice

Which of the following best explains how the structure of water allows it to dissolve so many other molecules

• Water molecules are polar, with positive partial charges on hydrogens, a negative partial charge on oxygen. Other polar molecules and ions interact with the partially positive and negative ends of water, allowing it to dissolve.

• Water molecules are polar, with positive partial charges on hydrogens, a negative partial charge on oxygen. Other non-polar molecules and ions interact with the partially positive and negative ends of water, allowing it to dissolve.

• Water molecules are nonpolar, with positive partial charges on hydrogens, a negative partial charge on oxygen. Other polar molecules and ions interact with the partially positive and negative ends of water, allowing it to dissolve.

• Water molecules are nonpolar, with positive partial charges on hydrogens, a negative partial charge on oxygen. Other non-polar molecules and ions interact with the partially positive and negative ends of water, allowing it to dissolve.
