Survival Traits and Environmental Impact

The video guides students through Amplify Lesson 1.4, focusing on investigating changes in trait distribution through natural selection. It begins with an introduction to the lesson, followed by a warmup activity analyzing histograms of fur traits over generations. Students then run a simulation to observe natural selection in action, adjusting environmental conditions to see how traits change. The video discusses the concepts of environment and adaptive traits, and students use a modeling tool to predict trait changes. Finally, predictions are tested, and the lesson concludes with a summary.

What is the main focus of Amplify Lesson 1.4?

• Exploring chemical reactions

• Studying the solar system

• Learning about the water cycle

• Investigating changes in trait distribution

What do the histograms in the lesson represent?

• Distribution of fur level traits in a population

• Distribution of fur color in a population

• Distribution of weight in a population

• Distribution of height in a population

How many types of Australis are shown in the first histogram?

• Five

• Four

• Seven

• Six

What environmental change is simulated in the lesson?

• Temperature change to cold

• Decrease in sunlight

• Increase in rainfall

• Increase in humidity

What happens to the Australis when the temperature is changed to cold?

• They change color

• They shiver and fall over

• They migrate to a warmer area

• They grow more fur

What is an adaptive trait?

• A trait that decreases survival chances

• A trait that increases survival chances

• A trait that has no effect on survival

• A trait that is only found in plants

What is the role of the environment in the simulation?

• It provides food for the Australis

• It determines the survival of traits

• It has no effect on the Australis

• It changes the color of the Australis

What is the purpose of the modeling tool in the lesson?

• To create a 3D model of an animal

• To predict changes in trait distribution

• To measure the speed of animals

• To simulate weather patterns

What is the initial condition of population B in the simulation?

• Starting with no fur at all

• Starting with a wide distribution of fur levels

• Starting with the highest fur level

• Starting with the lowest two levels of fur

What should students do after running the simulation?

• Upload a screenshot of the results

• Write a report

• Draw a diagram

• Create a presentation
