Batty the Bat

I met some interesting people and bats at the FLC. Do you know what's so special about bats? If a bat gets a hole in its wing, it will heal because there are so many blood vessels. If you think bats are gross, it might be the other way around. Bats eat mosquitoes and other biting insects. I think this bat is cute.
I built a bat house. Bats like it warm, so we're painting it dark brown.
People from the Fish & Game department taught us about bats with a great slide show. I got to advance the slides!
I also met someone from Animals in Distress. They do good work helping sick and injured wild animals. On some days this spring and summer, I am going to sell my delicious homemade dog biscuits and some other items to raise money to help Animals in Distress. I already have permission to sell them outside a store.

I'm all heart!

Dissecting the pig hearts was stinky! My group and I found the atriums (atria?) and ventricles of the heart. You can remember which is which by making an A a V with your fingers. The atrium is at the top and the ventricle is at the bottom. They go: squeeze, squeeze, coast. In the first picture you can see I was working in a team with some 5th and 6th graders at the school where my Mom works. We also found the valves, and the chordae tendineae, which look like parachutes with cords. The chordae tendineae shut the valves. They're the white things in the second picture.

We also stuck our fingers through the veins and arteries. They are tougher than you think. Before we got to start dissecting, we met a man who has had a heart transplant.
I am blogging this late, sorry! The heart dissection actually happened on Valentine's Day. Ha!
