This afternoon we went to the playground to investigate the first signs of spring. Armed with our five senses, an investigation sheet, and a pencil, we made insightful observations of the signs of spring.
We have been greatly enjoying our science studies this year. Let's look back at our science studies since the beginning of the school year. In the fall we learned to classify things into living and non-living. We then classified living things into plants or animals. Then we classified animals into vertebrates and invertebrates. We learned that we are vertebrates! We began comparing and contrasting the characteristics of the five vertebrates: birds, mammals, reptiles, amphibians, and fish. We then began looking at each group individually.
The first group that we studied was birds. We learned that birds have feathers, wings, and clawed feet. Birds build nests out of a variety of materials and lay eggs in the nests which hatch into baby birds. We set up several bird feeders around the building, giving us great views out of our classroom windows for some excellent bird watching! When winter arrived we talked a lot about animal adaptations for winter. We learned that many birds migrate south to warmer climates in the winter. Now that we are welcoming spring we are beginning to notice birds that have returned.
We then talked about mammals. We learned that mammals have hair or fur and not feathers, they have four limbs, and their babies are born live. We looked at field guides of mammal tracks and then went outside to look for mammals tracks on our playground. We found some squirrel tracks and some tracks that were suspected to be either fox tracks or from a cat.
After our studies of mammals, we talked about reptiles and amphibians. We learned about the differences between reptile's and amphibian's bodies and eggs. Our trip to the Children's Museum in Portland supported our studies of reptiles and amphibians with a wonderful hands on program. We got to examine one of the turtles from their tank and learned that reptile eggs feel similar to rubber balls.
This week we began our study of the human body, because we are mammals too! We will be learning about our own body parts. We will be learning that we are omnivores and that we need to eat a variety of healthy food to keep our body healthy. We will be learning about classifying food into food groups and learn about the food pyramid.
We have also begun botany studies of seeds and the parts of a flower. We have begun our indoor planting to prepare for our garden!
