Students in Ms. Clark's classroom have been exploring the science of greenhouses through a hands-on experiment over the past few weeks. They planted grass seeds in two small containers—one placed inside a plastic bag and the other left exposed to the open air.

Throughout the experiment, students carefully observed their plants. In their latest observation, they noticed a striking difference: the grass inside the plastic bag had grown extensively, reaching 9 inches, while the grass outside had grown very little, only about 1 inch or not at all.

Students also observed water droplets forming inside the bag, which helped them conclude that a small-scale water cycle was occurring inside the sealed environment. This cycle created an ideal climate for the grass to thrive, demonstrating how greenhouses help plants grow by trapping moisture and heat.

As a class, students recorded their observations and discussed the key differences and patterns they noticed over the weeks. This experiment gave them a hands-on understanding of plant growth, the greenhouse effect, and the importance of controlled environments in science.
