I am writing to send my heartfelt thanks for your support of my "Please Bug Us!" Project.
With your help I was able to purchase materials for an invertebrate museum in the science lab of my elementary school. The area is clearly designated in the classroom, and as you may imagine, students are constantly checking out the movements of the many critters.
Thus far, I have used the materials in Grade 1 to bolster the Animal Diversity unit. Students were able to observe and touch the pill bugs, roly polies, Bess beetles, millipedes, grain beetles and mealworms. However, the students are mostly enchanted by the hermit crabs and their ability to hide inside their "apartment" shell that they rent for free. The first graders constantly ask me if hermit crabs have moved to a new "apartment" when they enter the lab. They really would love to see the soft spot on the hermit crab belly.
In the 4th grade, I was able to greatly enhance the unit on Animals and Plants in Their Environment. We used the ants to elucidate the concept of life span, since the ants in captivity last for just a brief time without a queen. We were able to witness the 4 stages of the grain beetle life cycle, build a habitat with all necessary requirements for the pill bugs, and watch the termites instinctually follow the scent trail left by a ball point pen. The life in a rotting log kit continues to assist in bringing meaning to the word decomposer, as we have few trees in our very urban area, and fallen trees are removed immediately. For fun, we tested the strength of the mighty Bess beetles by having "chariot races". The Bess beetles were humanely put to test to pull a Petri dish full of paperclips. So far the strongest Bess Beetle carried 8 large paperclips—not too shabby!!
In addition, I will be able to use the materials in instruction for both 3rd graders and 5th graders at the end of the year. The 3rd graders study Plant and Animal Adaptations, and the 5th Grade unit Exploring Ecosystems will both make good use of the invertebrates. Needless to say, these two grade levels greatly anticipate the end of the year. They can't wait to make closer observations.
The living materials not only serve to enhance my teaching of the state standards and curriculum, but they are also extremely motivational. In fact, I have inadvertently assembled a core group of students who come to me during their lunch to assist in caring for the animals and maintaining their habitats. These students actually seek out the chance to clean up, and their assistance has made these tasks much more manageable for me. Further, one student has emerged as a true scientist. His sense of wonder, his curiosity, and the time spent making observations and researching far surpassed anything I expected of my students. In fact, I don't even have his class for science, yet he visits the animals daily and I can count on him to check in if I am out sick. I cherish the thought that this invertebrate museum will push him one step further into the field of science, where we so desperately need young, inquisitive minds. Many thanks for your support of my students and their sense of wonder.”
