Analogs are used in science investigations to better understand systems we can’t access ourselves. In this lesson, students explore the Dry Valleys of Antarctica to better understand microbial communities on early Earth and what might have been possible on ancient Mars. Students will examine photographs, written descriptions, and artistic renderings of early Earth, the Dry Valley lakes, and
This article summarizes the research of cyanobacterial mats in Lake Joyce during the 2014 field season. It describes the importance of the mats to better understand Earth history and understanding of other planetary systems. Additionally, it describes the sediment trap experiement that will conclude in the next field season.
On 6 October 2014, Capital Public Radio in Sacramento, CA interviewed Dawn Sumner, Tyler Mackey and Lucy Coleman on connections between the research in Lake Joyce, Antarctica, and work by the Mars Curiosity rover. To listen to the interview, click here.
In this lesson students research scientific field expeditions and learn what it is like working in the field. Students are able to ask questions of the research team as part of their project. Students then share what they have learned with their classmates.
Objective
1. Students understand what really goes on in the field during a scientific study.
2
An important science skill that needs to be developed is asking significant questions that advance knowledge. This activity helps students to understand the difference between significant and trivial questions.
Objective
Students should be able to distinguish between significant questions that advance knowledge and trivial questions.
Procedure
1. Have the students define significant question and trivial questions in a
