Unit 4 Test Results
I am so proud of my students. We have pushed hard to get through our curriculum this year and then we were faced with two snow days (some students actually have had 5 and have not returned yet!) less than two weeks prior to our EOC exam. They have not let the snow days get in the way at all. We have condensed and split up tasks and plowed ahead. Everyone had to take the Unit 4 - Heart Disease test after our snow enforced long weekend and they did great! I can honestly say that these are some of the hardest working students I have ever had the pleasure to teach. After all is said and done, they averaged an 88% on this test with no one scored below a C. Way to go and keep it up! EOC is one week away from today.
Ugly Sweater Holiday HOSA Event
We had a nice turnout for our Holiday Party last night. All HOSA programs were represented (PLTW Biomedical Sciences, Fire Science / EMT, Health Services / CNA). We all enjoyed some tasty holiday food and an "Elf Yourself" or two. My biological kiddos got to come to the party too and had a great time. My daughter participated in the gift exchange and was ecstatic about receiving a large amount of chocolate. It was great to just get together!
Today students ran an EKG on themselves. We used this activity to introduce the electrical "wiring" of the heart. Students added this information to their heart boxes and learned the basics of an EKG. They used LoggerPro to analyze their own "waves" and went back to Anna's medical history to analyze her heart health.
Today students worked with blood pressure. They were introduced to the sphygmomanometer and stethoscope in order to practice taking blood pressure. The point was to expose the students to this skill, but not to necessarily master it. We moved on to using Blood Pressure probes with Logger Pro to utilize our technology to quickly and accurately find blood pressure. Students spent time reworking their previous experiments in order to test blood pressure. This time around we emphasized the experimental design process.
We took out our Lab Quest Minis, Logger Pro software and Hand Grip Heart Rate Monitors in order to play around with heart rate a bit. Students learned how to use the probes and then designed their own experiments to test how their variable of choice affects heart rate. This year my students were creative! Some of the more creative ideas included:
Students completed an experimental design for their question that required them to write their own procedure. To conclude the activity they wrote their first formal lab report of the program.
The long awaited heart dissection day finally arrived! My students have been looking forward to the day all semester. For many of them this is the first dissection they have ever done. Students labeled the external features of the heart prior to the internal dissection. Monday we will have a lab practical quiz over the structures of the heart.
Today we continued working on the path of blood through the heart. The class formed two big groups and brainstormed a way to represent the heart, valves, major vessels, blood cells and the lungs in a giant walk through heart. Each student in the group had to walk (and talk their way) through the heart. I enjoyed some of the creativity they exhibited given the fact they only had about 15 minutes to pull their walk through heart together. We spent the rest of the hour learning more about poor Anna and her additional health problems. We also looked at an artery and vein under the microscope. We are gearing up for our first dissection - it's finally here! Tomorrow is the big dissection day!
New unit! Today we started the "Heart" unit. The whole purpose of today was to introduce students to the path of blood through the heart. We made "Heart Boxes" to represent the path of blood throughout the heart and circulation. Although these boxes aren't anatomically correct, they do a great job at making the students think about how blood gets from one part of the heart to another. We will learn all about the actual anatomy of the heart in the days to come.
