Lesson Title: Natural Selection

Subject: Middle School Biology

Overview:

Watch out! In this computer simulation, bunny rabbits may take over the world!

This lesson provides students with opportunities to practice a natural selection activity using technology skills in the science classroom to promote student engagement and motivation.

Both a short video clip and a computer simulation activity are used during class. The video clip allows students to activate prior knowledge about Charles

Darwin’s theory of evolution through natural selection, while the computerized animation allows students to interact with manipulating factors that influence species¿ survival (adaptation, overproduction, variation, competition).

Vocabulary words covered in this lesson: species, adaptation, evolution, natural selection, variatio n, mutation, competition, and over production.

Grade Level: 6-8 th grade

System

Requirements:

Primary Website

Used:

Equipment: Computer with Internet access, projection unit, speakers.

Simulation by PhET Project ~ http://phet.colorado.edu/en/simulation/natural-selection

The PhET Project is created by the University of Colorado at

Boulder as part of their collection of fun, interactive, researchbased simulations of physical phenomena.

Science Concepts: Genetic variation and environmental forces influence diversity of organisms.

CA Science

Standards:

The four factors of natural selection that support the theory of evolution are overproduction, natural selection, competition and variation within a species.

7.1.3 Explain how natural selection leads to evolution.

• 7.3 a) Students know both genetic variation and environmental factors are causes of evolution and

• 7.3.b Students know the reasoning used by Charles

Darwin in reaching his conclusion that natural selection is the mechanism of evolution.

Creativity and Innovation :

1.

Students demonstrate creative thinking, construct knowledge, and develop innovative products and processes using technology.

2.

Students: (c) use models and simulations to explore complex systems and issues.

3.

Research and Information Fluency: Students apply digital tools to gather, evaluate, and use information.

4.

Students: (d) process data and report results
