Vital Capacity of Lungs

This week in science we further explored the systems of the human body. We learned about the respiratory system and how the lungs are important for the exchange of oxygen to our red blood cells and the exchange of the waste product C02 from the blood. The connection between the circulatory system and respiratory system was focused on. In this week's lab, students measured their lung capacity to further understand how a larger person requires a larger set of lungs so that more oxygen and carbon dioxide exchanges can take place simply due to the person having more cells in his or her body. Not surprising, the larger students in class had larger lung capacity and those smaller students had less lung capacity. Students involved math by finding the average of three of their exhales.

Making a Working Model of the Heart

As we continue to learn about systems, we have recently ventured into learning how the circulatory system transports nutrients to the cells in our bodiy. Thursday our class teamed up with Mrs. Espinosa's class to create a working model of the heart. Students had cups, containers, one-way valves, tubes, rubber stoppers and more. Their challenge was to use what was recently learned about the heart to assemble a model of it. Groups did amazing. In the end, all groups had a heart that could be "pumped" by squeezing one container. This pressurized the container and pushed "blood" (water) out of that ventricle into the lungs. Then the other side of the heart would "pump" by being squeezed, sending water from that ventricle to the body. Additionally, each time the squeezing stopped, water would be suctioned into that part of the heart from the "body" or the "lungs" cup. The complete cycle ensured water never ran out.

Coding the 13 Colonies

Today we started a multi-week task of coding are Spheros robot to go on a journey through the 13 original colonies. Students will have the robot start on an X outside the colonies and code it to go to Virginia, the first colony that was established. Once at that colony, it will speak and tell why it was founded and the year that it was founded. From there they will code it to go to the rest of the colonies in order of when each colony was founded on the map on the floor. Our programs will eventually be utilized by Mrs. Espinosa‘s class, as they will be able to come over and learn about the 13 colonies through our students' coding programs that they created.
