Last October, a really spectacular space opened up on campus – we now have a dedicated Maker Space! Loads of equipment, including: vinyl cutter, embroidery machines, sublimation printer, oscilloscope, Arduino, soldering station, engraving machines, laser cutters, Carvey mill, and a virtual reality set up. Oh, and of course, we have 3D printers.

The penultimate day of the summer term! Compared to some of our other days, this one was pretty low key, but we did have a little unexpected adventure.
I’d intended to lecture on ecosystem services in the morning, and then watch one of my favorite “teaching” films, “Hurricane on the Bayou.” And this is mostly what happened, except for a little detour part way through. When I arrived on campus, I noticed some flyers posted in the science building – one of the biology grad students, Vanessa Dodge, was giving her thesis defense. Not only was I really interested in her research, as I’d been up to the field site in Point Reyes a couple of times, but I also thought this would be a good way for my students to learn a bit more about the process of science. So, I gave them the choice – do you want to listen to me lecture all morning? Or do you want to go hear someone else talk for a while? They voted in favor of variety, so about an hour into the day we headed upstairs to the thesis defense.

Hundreds of elementary and middle school children swarmed the cafeteria, dorms, quads and halls of Sonoma State University Thursday for what’s becoming an annual tradition.
It’s the second year the Rohnert Park campus has hosted “I Am the Future Day” for the Sacramento nonprofit Roberts Family Development Center, which provides academic and other services to hundreds of economically disadvantaged children and their families. The event is intended to give children a “taste of college” to encourage them to pursue higher education.

We covered a lot of ground today. We started out with a lab activity, since we hadn’t had time to explore biomes fully the previous day. I started them out with a super cool Google Earth file that I found here. One of the resources is an interactive Google Earth map with layers that show various aspects of climate – average winter temperatures, average summer temperatures, that sort of thing – along with a layer that shows the location and distribution of biomes, worldwide.
Not a whole lot to post about this day . . . once again (as usual on exam days), I didn’t take any photos. Our morning was taken up with the third exam, including an exam review session. No Pictionary this time, though . . . instead, I put together a game of Jeopardy, using this awesome Powerpoint template.
Another favorite day! And another rotation lab. Today’s lectures focused on the diversity of vertebrates. We started out with chordates, and then followed the major groups all the way through their transition to land. In the morning, we covered fish, amphibians, and (some) reptilian vertebrates. Then, we stopped for some lab activities that allowed them to explore further the transition to land.
First, an activity from the National Science Foundation’s National Center for Case Study Teaching in Science, “A Strange Fish, Indeed,” This interrupted case study describes the extraordinarily COOL discovery by Marjorie Courtenay-Latimer of a living Coelacanth – a sarcopterygian fish from an order believed extinct for 70 million years. This is one of my very, very favorite biology stories, and I did touch on it briefly in lecture, but working through this case study, which allowed the story to unfold gradually, was wonderful. On the whole, I’ve found that the case study activities put out by the NSF are excellent. I used this one as is, without any modifications.

Taking a quick break from Summer School posts to share something that happened on campus today: the school hosted about 450 elementary-aged students from the Roberts Family Development Center, a CDF Freedom School. Departments from all across campus set up hands-on activities, the Rohnert Park Fire Department and Police Department came out to say, “Hi,” and it seemed as though a good time was had by all!
Read moreI know I keep saying this, but THIS IS ANOTHER OF MY FAVORITE DAYS OF THE SEMESTER! Today was pretty much fun from start to finish. In the morning, lecture on the diversity of plants, including the various adaptations that allowed plants to make the transition from the ocean onto land. After the lecture, I’d arranged for us to have a tour of the Tropical Greenhouse on campus. The greenhouse is across campus from the science building, so along the way I gave them a little walking tour of some of my favorite plants on campus, including a few Ginkgo trees, a Cycad (my all time fave), several ferns, redwood trees, and the Butterfly Garden. Unfortunately, I didn’t get any pictures along the campus tour, but I have loads of pics from our greenhouse tour! We were welcomed to the greenhouse by Kandis, who provides instructional support for the Biology Department, and she is an exceptionally gracious hostess!
To be honest, for most of my time at SSU, I didn’t know we had a tropical greenhouse. It was only when I was teaching this class last summer that I found out about it, but now I want to bring as many students here as possible. It’s not all that big, but there are so many GORGEOUS plants!
Today, it was time to leave microevolution behind, and talk about how new species form. Now that they understand how adaptations and natural selection cause populations to change, it’s an easy step to understanding how this can lead to speciation. To drive that concept home, I put together a speciation activity based on this cool online natural selection simulation: http://sepuplhs.org/high/sgi/teachers/evolution_act11_sim.html.
The simulation tracks populations of birds on an island, to see how natural selection and mutations can cause phenotypic changes. You start with 3 populations of 300 birds each, and follow them through 1,000,000 years of evolution. Throughout this time, the simulation makes a notification any time a mutation takes place, along with the overall effect – was it positive or negative? Did it help to increase, or decrease the population?
Today we covered sort of a hodge-podge of things, but there was a common thread – ways in which we can see evidence of evolution, both on long time scales, as well as short ones.
First things first, though – Exam #2. Before the exam, we played a game of Pictionary, using the following prompts:
| Allele | Anaphase II | Character vs Trait | Directional Selection |
| Disruptive Selection | Function of tRNAs | Gene Flow | Genetic Drift |
| Haploid Cell | Homologous Chromosomes | Incomplete Dominance | Integumentary System |
| Metastatic Tumor | Nervous System | Phases of Mitosis | Prophase I |
| Recessive Pedigree | Replication | Transcription | Translation |
