8th Grade gets a Valentine’s Gift!
Today we were fortunate to have Dr. Mike Howe arrive, by chance, in our classroom. He was touring the school as a perspective parent looking at Pathfinder for his son. The best part was he just happened to be a cardiologist and we just happened to be dissecting a pig’s heart and lungs! Dr. Howe gleefully jumped right in and explained the workings of the heart to the 8th grade. He discussed and dissected the valves, explored the 4 chambers and talked about heart disease and it’s causes. He asked great, challenging questions of the students and they asked many of their own. It was truly awesome and such a great gift to have a passionate professional stop by at the perfect time!

His favorite valve is the aortic valve 🙂
6th grade Explores Changes of State
The 6th graders are studying matter and how adding (endothermic) energy or taking away (exothermic) energy changes the state of matter. In the name of science we had to make No Bake cookies and a smoke bomb. By visualizing how the molecules move, the concepts of solid to liquid, boiling, melting, condensing, and sublimation were all better understood by these delicious and fun activities.

7th Grade Probiotic Science
The 7th grade made yogurt while studying bacteria. They invited their 5th grade buddies to help. Each group came up with a way to prove the bacteria in the yogurt uses the lactose in milk to form lactic acid and thus yogurt. With the milk yogurt as the control the different groups tried soymilk, almond milk, and heavy cream. Another group chose to add lemon juice because they felt it would stop the bacteria from reproducing. All creations were tried and some considered downright gross! Be sure to read about this experiment more on the individual 7th grade blogs.

3D Printer First Project
Mr. Matt is planning on taking the 3rd and 4th graders ice fishing with poles they are making. He needed a reel and was going to try to put together something with ball jar lids and thread bobbins. Instead we had the 6th graders come up with a design on TinkerCad a 3D soft ware program. It worked! Check out the pictures.
Now all they need is for the weather to warm up from 10 degrees F!
