This 13-minute video lesson provides a spectrophotometry Example: determining concentration based on absorbance. [Chemistry playlist: Lesson 101 of 106].
Students learn about the advantages and disadvantages of the greenhouse effect. They construct their own miniature greenhouses and explore how their designs take advantage of heat transfer processes to create controlled environments. They record and graph measurements, comparing the greenhouse indoor and outdoor temperatures over time. Students are also introduced to global issues such as greenhouse gas emissions and their relationship to global warming.
