(ED492) Week 3 - How the World Evolves

​Bellwork #3: One-Quick Question

​How has life on Earth changed over time?

How the World Evolves: Part I

Remember: you evolve with the world.

​You are not left behind.

​- Mr. Tim

​

• Explain what evolution is.

  Determine how evolution has affected living things.

  Contrast the two types of evolutionary selections.

  List and explain the four parts of natural selection (Acronym: OVSA).

  Perform an experiment that showcases evolution.

Your Objectives:

​

• ​What evidence supports the theory of evolution?

• ​What is the theory of evolution by natural selection?

• ​How can humans influence the traits of a population through artificial selection?

• ​How does natural selection change species over time?

• ​How has life on Earth changed over time?

​The Essential Five:

​1. What evidence supports the theory of evolution?

Evolution is a process ​of how populations change over time.

​

​Examples:

• ​ Finches - a type of bird - have bigger beaks.

• ​ Chickens are bred to have larger combs and wattles.

​* Explain what evolution is.

​* Determine how evolution has affected living things.

​2. ​How can humans influence the traits of a population through artificial selection?

Artificial selection is when humans breed living things for certain features.

​

​Examples:

• ​ Dog breeds such as chihuahuas.

• ​ Teosinte to corn.

​* Contrast the two types of evolutionary selections.

​3. ​​What is the theory of evolution by natural selection?

Natural selection is when living things inherit traits to help them survive.

​

​Examples:

• ​ The hilitai - a lizard with a large size.

• ​ Cockroaches, which have been here for 280 million years.

• ​ Pokemon (Gotta' Catch Em' All :)

​* Contrast the two types of evolutionary selections.

​4. ​​How does natural selection change species over time?

Natural selection happens in four steps.

​

​Meet Madame Ovsa:

​

• ​ Overpopulation

• ​ Variation (Natural Differences)

• ​ Selection

• ​ Adaptation

​* List and explain the four parts of natural selection (Acronym: OVSA).

​5. ​​How has life on Earth changed over time?

​

• ​ Adaptations become common.

• ​ Living things looks different.

• ​ Some species survive longer.

• ​ Some species may mutate, or have a change in genetic material.

Recap: The Essential 5​

• Species evolve, or change over time.

• Artificial selection is when humans breed animals.

• Natural selection is when animals inherit traits.

• For natural selection, remember Madame OVSA. ​

• ​ Evolution allows the world to adapt, differ, and survive.

ACTIVITY: Watch and Learn

Let's see what you know :)

The Task is Simple:

​

• You will be divided into pairs.

  You will be shown a creature using a certain program:

  You will have a one-minute discussion on whether the creature will be able to move or not.

  Afterward, you will preview and answer the following questions in an online survey.

Assessment: Artificial or Natural?

​Bellwork #4: One-Quick Scenario

​Let’s say you were a biologist who was tasked to breed a new type of animal. What animal would you create? What features and traits would it have? You may write about it or draw your animal. The choice is yours.

How the World Evolves: Part II

Remember: you evolve with the world.

​You are not left behind.

​Quizizz QuizCheck: Unit 1.2

Let's see what you know :)

Here are your QuickCheck Questions:

The task is simple. You will answer the questions as a class.

​

​a.  What are the two types of evolutionary selections?

b.  What are the four steps of natural selection (OVSA)?

ACTIVITY: The Frog Test

Let's see what you know :)

Here is What to Do:

• You will be divided into pairs: one person as the folder, and the other person as the tester/writer.

  The pairs will have 7 minutes to fold their small frogs first, then 7 minutes to create their large frogs.

  Afterwards, the folder will test how many times the writer can catch the small frog in one minute - and write it down.

  Then, there will be a second trial – but with the larger frog.

• Finally, there will be a final question about how the experiment relates to evolution.

Assessment: Why Do You Change?

Why do you evolve?
