Description

  • Aligned with Big Idea 4 and Essential Knowledge 4.A.5, 4.A.6, and 4.B.4
  • Emphasizes Science Practices 3, 5, 6, and 7

Help your students make a big picture connection across communities and populations by characterizing food webs and other factors, such as predation and abiotic factors. Students master the Winkler titration method for measuring dissolved oxygen concentrations. Using this tool, they measure dissolved oxygen fluctuations to assess the relationships between species in an aquatic food chain (Daphnia, Chlorella, and Hydra). After understanding the dynamics of the aquatic food chain, students introduce new variables to design their own experiment using the producers and consumers.

The 8-Station Kit includes enough materials for a class of 32 students working in groups of 4. The 1-Station Kit includes materials for 1 group of 4 students. The digital teacher's manual is a 12-month eBook license to the Species Interaction Kit teacher's manual. You can also access the digital student guide for this kit for free on Carolina Science Online®.

Note: Kit includes 2 vouchers to request perishable materials in 2 shipments about 2 weeks apart; kit cannot be shipped with perishables. Kit does not have a refill because most materials are completely used during the activity.
