Seventh Graders Study Muscular and Skeletal systems

Students in Gary Poppinga’s and  Ryan Langel’s seventh grade science classes have been doing some interesting labs throughout the school year. The students have studied the muscular and skeletal systems and had the opportunity to perform a dissection on a chicken wing. The chicken wing lab was a great way for students to see some important structures such as: tendons, ligaments, bones, fat, epithelial tissue and muscle. During the digestive system unit, students participated in a lab by using household items such as: panty hose, sandwich bags, Dixie cups, water, graham crackers and bananas that helped represent how food passes through the different organs of the digestive system from mouth through to elimination. The students are in the process of studying the circulatory system; students will be able to participate in a pig heart dissection. Students will see the four chambers of the heart, the aorta, the pulmonary arteries and pulmonary veins along with heart valves. The science classes will be studying the nervous system immediately after completing the circulatory system and the students will have an opportunity to dissect a sheep’s eye. The students will be able to identify the lens, cornea, sclera, retina, and optic nerve. It has been a wonderful year in science and Mr. Poppinga and Mr. Langel feel that the children have been outstanding learners in the classroom.
