Description: This is one of the most scientifically-accurate activities I've seen for explaining the greenhouse effect. The rationale stated for this activity (how phytoplankton in the Antarctic act as a CO2 sink) has several problems, including (1) this activity has nothing to do with phytoplankton and (2) photosynthesis by phytoplankton in the Antarctic is also affected by high nutrient levels.

Summary of Reviews

Reviewer: Carrie Morrill 4 stars
Comments: Activity demonstrating how greenhouse effect works using jars, heat source, thermometers, and candle. The activity is well-designed, but its presentation on this webpage could be significantly improved, including rewriting the rationale and presenting steps and information in a more logical order.

Reviewer: Kirsten Butcher 3.5 stars
Comments: With proper educator guidance, students could benefit from this hands-on activity. But the directions are confusing so students will need support in integrating knowledge with experience here. Assessment activities could be improved to include more thought-provoking questions that tie into larger concepts more directly.

Reviewer: Robert Croft 4 stars
Comments: Great Activity. Has a lot of Setup and lesson plan organizational problems, however, it is a good hands-on activity for the teaching about a difficult concept (explaining how a greenhouse gas works) that makes this worth using.
