During this six-lesson unit the second-grade students estimated and accurately measured objects in the space and perimeter. The students calculated the area of the space and used square units to plan spaces and garden beds.

Each week our students participate in a full day field experience designed to connect, explore and engage with the outdoors. These five lessons were all a part of those experiences. Our focus this year was on gardening. All of these lessons took place in the school garden on campus, Our school district has a greenhouse for us to start seeds in and our garden uses primarily raised beds. The students also traveled to a local greenhouse to purchase supplemental plants, soil, mulch, hay, and other accessories.

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.
