In Science, we began our 3rd chapter over Adaptations. We discussed our first lesson and some new vocabulary words, including: adaptation, basic needs, and natural selection. We discussed different adaptations animals we are familiar with have that help them survive in their environment and how animals that are able to change their physical appearances, for example, to better blend in allow them to live longer and reproduce, the basic concept behind natural selection. And of course, it wouldn't be a new chapter without a new song to learn! See the above post to listen to our new song, "Adaptations"!
On Tuesday and Wednesday in Math we continued our quest to conquer subtracting whole numbers. Mrs. Elliott worked with some of us in small groups while others got to battle one another in a subtraction game.
In Science on Tuesday we did an experiment to test bird adaptations, specifically the adaptations of bird beaks. We tested a few different types of beaks (tweezers, spoons and clothes pins) on a variety of different types of "critters". These included worms (cooked spaghetti), grubs (rasins), caterpillars (twizzlers), maggots and larva (cooked rice), sunflower seeds, and water. We had to hypothesize which beak we thought would work best eating each food, take careful obersvations, and finally come to a consensus as a group as to the best beak for each food. We had a blast!
On Thursday in Science, we continued our discussion of our second lesson, which was about how animal behaviors help them meet their needs. We also created sets of "Rummy Cards", where students researched an animal, including information about their shelter, space, food, water and arrangement/habitat and labeled and illustrated each card accordingly. Below are some examples, cards for an Opossum and the American Crocodile.
