Halloween is over, and you have a carved jack o'lantern sitting outside ready for the trash or compost heap. Don't throw that gourd away just yet! Or maybe you have a pumpkin or butternut squash that you're using to make some desserts and you can spare a few pieces for science!

In this class, students will learn that all living things have DNA,...
I am a certified chemistry teacher (grades 7-12) with 6.5 years of experience in the classroom. I have also taught freshman college chemistry. From these experiences, I have worked with a lot of different types of learners at various stages of interest and motivation- from high school students simply taking the class as a requirement to college freshmen chemistry majors passionate about the course with never ending questions. I can tailor my teaching style to fit the learner, and I do what I can to make it approachable by anyone.

If they have a test tube or graduated cylinder, that would be great too, but not a requirement! I'd also recommend having a piece of banana or strawberry on hand (frozen is fine) since sometimes, students have trouble getting a large yield of DNA from pumpkin- bananas and strawberries consistently produce great results.
