Understanding Histograms and Natural Selection

The video tutorial introduces eighth-grade students to the concept of natural selection using simulations in Amplify Science. It explores variation and distribution in populations, demonstrating how different traits affect organisms. The tutorial explains histograms as a tool for visualizing variation and provides a practical demonstration using pocket change. Students are assigned to experiment with simulations, watch a histogram video, and complete homework to reinforce learning.

What is the main focus of the Amplify Science simulation introduced in the lesson?

• Genetic engineering

• Artificial selection

• Photosynthesis

• Natural selection

In the simulation, which organism is considered the primary consumer?

• Newts

• Karna Thon's

• Thorn palms

• Austral OPA

What can be adjusted in the simulation to observe changes in the traits of organisms?

• Temperature

• Weather conditions

• Time of day

• Amount of variation

What type of graph is used to show variation in populations?

• Scatter plot

• Histogram

• Pie chart

• Line graph

How do histograms help biologists?

• By showing variation of traits in a population

• By measuring the speed of evolution

• By predicting future traits

• By identifying new species

What is the purpose of sorting pocket change in the demonstration?

• To clean the coins

• To identify rare coins

• To create a histogram

• To calculate total value

What does a histogram with no variation look like?

• All bars are of different heights

• All bars are the same height

• Bars are arranged in a circle

• There are no bars

What is the new term introduced in the lesson related to histograms?

• Population

• Variation

• Distribution

• Generation

What is the assignment given at the end of the lesson?

• Draw a diagram of a food chain

• Conduct a survey on favorite animals

• Create a histogram using pocket change

• Write an essay on natural selection

What is the definition of distribution as used in the lesson?

• The genetic makeup of a species

• The migration pattern of animals

• The number of individuals of each trait in a population

• The spread of organisms across different ecosystems
