Week at Holy Family
posted by: abeebe
I had a wonderful week out at Holy Family with Mrs. Jeanne DuBois and her 5th grade students. Here are some of the week’s activities:
Students are carefully harvesting the zebrafish embryos with a fine mesh net.
Students then empty the collected embryos into a petri dish. The student is making sure to look over the mating tank so that she is sure she hasn’t left any of their babies behind!
If students did not have embryos in their mating tanks, they would go to the “adoption center” and adopt some from their (generous) fellow students.
Here students are cleaning out unfertilized eggs using a pipette. It is very important to clean out any contaminants that might harm the healthy zebrafish embryos.
Once the petri dish is cleaned, students then move to microscopes to observe their embryos.
Here a student is recording what his embryo looks like at that particular stage of development. He will have 4 days to see how this embryo grows and changes over the week.
If there are some interesting specimens, students are able to show their images by using the projection microscope and pointing out their findings to the class as a whole.
Here are some pictures of the hard working students and Mrs. DuBois.
