Science applications in agricultural practice
This activity provides opportunities for students to research and prepare a presentation outlining the contributions of science (both positive and negative) to agricultural practice.
Science and Society
6.2 Students use scientific concepts to evaluate the costs and benefits of applications of science (including agricultural and industrial practices).
- Poster-size cardboard
- Access to resources for researching information
This activity can be done in a number of ways including:
- a written assignment
- a poster presentation
- a class debate.
Time: 30 minutes + un-timetabled research time
- Accessing resources
- Selecting and justifying
- Arguing a position
- Supporting decisions
Students, working in groups of three, select one of the following topics (or any other relevant topics). The group prepares a concept map linking the main ideas of the topic selected and including examples that conflict with or help support the topic statement selected (i.e. positives and negatives).
Applications of science in agricultural practice
- Science can help develop new agricultural techniques that are environmentally friendly.
- Science has led to the development of higher-yield, pest-resistant agricultural products.
- Science can help to remedy environmental degradation attributed to agricultural practice. (e.g. soil erosion, decline in soil fertility, loss of soil structure, salinity, pollution…)
- Science has been involved in the development of agricultural practices that have had negative effects on humans and the environment.
After group discussion students research the topic statement they have selected and prepare one of the following presentations:
This is a critical essay (or it may be presented in the report genre) examining the topic. The length of the assignment and the genre used will depend on the abilities of the students, but it will include the following main issues:
- the scientific core content associated with the topic
- specific examples that support or conflict with the topic.
Poster or multimedia presentation
Students develop a poster, web site, or other multimedia presentation (such as PowerPoint) to illustrate the main points of the issue or topic.
Students argue the facts for and against each statement, giving illustrative examples that help support their arguments.
Gathering information about student learning
Sources of information could include:
- students’ concept maps (see Activity 11)
- student presentations (essay/poster/multimedia presentation/debate) of the topic statement
