Use little water in the concavity of the slide and then the cover will not be required, preventing the Daphnia from being squashed.
 * Suggestions and Improvements**

Many options for altering Daphnia heart rate, caffeine, alcohol, other solutions, various concentrations of solutions, various types of water.

Provide students with a diagram of Daphina so they can easily find the heart.

Check out the deep cavity slides that LouAnn had with her lab. They're a bit expensive but they are great for this type of lab. I have a problem with the concave slides. They don't work well with a coverslip, the kids slop liquid all over the stages if you don't have them and if you double them up you smash your specimen.

George - This lab is really neat! The kit comes with a ton of useful equipment and is worth the cost. It would be useful to review microscope technique prior to doing this lab. Great and good results.

Keith - Not having looked at Daphnia before, I wasn't sure of what to look at.

Susan - I was also not familiar with Daphnia. I was able to quickly find a labeled diagram online. Computer research could be a required prerequisite for the students to participate.

Carrie- I would definitely utilize this lab in an anatomy class! The kit provides numerous lab options and includes equipment that can be used in other labs throughout the year. The lab is expensive at first, however, after the initial purchase the cost is minimal.

Kathy - Lots of activities and equipment for a small price.

Salima-Great activity! You can do a variety of things and see what happens. Students would definitely get interested in looking at Daphnia. Maybe have a poster that shows the anatomy and some background information or just a handout.

Deb- This was a fun lab. Unfortunately, I don't teach anatomy, and I can't see how I'd fit it in but I bet Tracy (our anatomy teacher) would love it, so I'll show it to her. The Daphnia was fun to work with and they can always be used as food for hydra when you're finished using them.

Christine- I did this lab with our AP students at Culver but we had to do the part with the daphnia with theoretical data due to time constraints. The students had a great time with the first section! I loved being able to do this with the daphnia! I think the students will be able to gain an appreciation for the complexity of circulatory systems in organisms other than themselves in addition to learning the objectives that this lab strives to meet.

Alicia- Great lab, loved the lab because of the use of daphnia! I can see use in anatomy.

Emily- I'm looking forward to using this lab in my classroom. I like the many components and the ability to make it more or less inquiry based depending on your classroom needs.
