​WEEDS OF MASS DESTRUCTION

Pedagogical Purpose

​This activity allows students to explore a current controversial issue in science using the web. Students are given a set of verified, useful resources to kickstart their investigation, but must also utilize their research skills to discover resources of their own. The information they gather from online resources is then used to create a presentation to convey their unique outlook on the issue at hand. Students are given freedom in deciding what tool to use for their presentation, which provides them with a sense of ownership and fosters creativity. 

 

Working in groups allows students to develop cooperative research skills. Multiple perspectives expand their consideration of the issue, and reinforce the collaborative nature of scientific inquiry. The classroom debate that follows the group presentations provides another avenue for students to practice exploring and respectfully challenging perspectives that differ from their own.

 

This WebQuest is designed to take approximately two classes, assuming 80 minute blocks. 

 

Curriculum Link

This WebQuest serves well as an Science, Technology, & Society activity for Unit B: Ecosystems and Population Change of the Alberta Biology 20 curriculum. The STS learner outcome that best matches this challenge is:
 

20–B1.1sts Students will:

explain how science and technology have both intended and unintended consequences for humans and the environment (SEC3) [ICT F3–4.1]

• assess the environmental consequences of the introduction of new species into established ecosystems (such as tropical fish in Banff Hot Springs, starlings, quack grass, scented chamomile, purple loosestrife) and discuss the responsibility of society to protect the environment through science and technology 
   

​Nature of Science outcomes can also be touched on as students complete this WebQuest. These include:
 

Initiating and Planning

20–B1.1s Students will:

formulate questions about observed relationships; plan investigations of questions, ideas, problems and issues; and define and delimit problems to facilitate investigation 

 

Communication and Teamwork

20–B1.4s Students will:

work collaboratively in addressing problems and apply the skills and conventions of science in communicating information and ideas and in assessing results 

• work cooperatively to make clear and logical arguments to defend a decision on a given issue, such as human impact on ecosystems, land reclamation or wildlife habitat preservation (CT–SEC1, CT–SEC2, CT–SEC3) [ICT C1–4.4]

• develop, present and defend a strategy to improve wildlife habitats (CT–SEC3) [ICT C1–4.4].​
