The 7th graders were able to conduct a study on decomposition in the science lab! In this lab, students put together four (4) little zip lock bags each containing 100ml of water and slightly different materials (one had potting soil and food scraps, another had sand and food scraps, the third had mulch and food scraps while the last one had just food scraps). Over the course of the week, the scholars were able to observe the decomposition process first hand and record data on which substrate (potting soil, mulch, sand or nothing) worked the fastest in the lab. The students concluded that the mulch and potting soil were working the best but more time is needed to observe which of the two would perform better. Overall this lab was very interesting to conduct and I’m sure it is one the kids will never forget.
