The Science Project is a year long project in Physical Science. It begins with a Background Paper, where the students research a topic of their own choice. Students then write an Investigation Plan. The Investigation Plan is based on an experiment the students design based on their Question (or Problem) and their Hypothesis.
Following the actual experiment, with clearly defined variables and an experimental group, students complete an Investigation Follow-up Report. In this report, they analyze their data, document trends, discuss their hypothesis, and tie what they learned back to their Background Paper. The last piece is to create a display to show off their work. This year, the senior Bible class served as judges.
In Mrs. Ivans’ chemistry class, students had some hands on experience with titration of acids and bases, take a look at some action shots below!
AP Biology students successfully inserted a jellyfish gene (green fluorescent protein) into E. coli bacteria, which caused the colonies to glow in the dark. Students below gather around the dark bacteria plates glowing in the dark!
AP Biology students were asked to research how proteins travel in and around a cell and creatively show their understanding. Period 3 students decided on a cell rap battle. Check out their impressive results (and lyrical rhymes) below!
This week freshmen Physical Science students measured static friction (the friction of the object resting on the surface) and the kinetic friction (when the object is moving over the surface) with different masses of objects over varying surface textures. Then students measured the force necessary to lift a block vertically and how that force is reduced when the object is lifted on an incline plane at three different angles. Before doing these activities, students learned all the various ways friction is part of our lives: gravel on icy roads, our fingerprints, the friction between our shoes and the ground…
Science in action!
AP Biology students had the opportunity to visit the Oregon National Primate Research Center recently. Students toured the Rhesus macaque outdoor enclosures and heard from Dr. Larry Sherman about his current research on demyelinating diseases (ex. Multiple Sclerosis). Dr. Sherman also joined students in the classroom to introduce a tissue staining project they will begin in class soon. Students will be analyzing mouse brain tissue with the goal of seeing how chemotherapy affects the brain’s ability to learn and perform neurogenesis (create new neurons).
Our Chemistry and Physical Science classes had a real treat today when Tom Wilson, who has a Ph.D in Fiber and Polymer Science, spoke from his extensive industry experience. In his work career Dr. Tom has been a part of NASA sponsored research, spent 11 years in medical applications of polymers, and 18 years at Nike. He also holds 13 US Patents. Most of the shoes the students were wearing contain polymers Dr. Tom designed!
The students learned how advertising can influence our ideas about chemicals and chemistry by studied a list of complex and scary sounding chemicals. Dr. Wilson was actually showing them the list of chemicals contained in the superfood Kiwi! He talked about how polymers are used in shoes, adhesives, and in many aspects of modern life.
When the students had the opportunity to ask questions, one asked what he liked most about working for Nike. He answered that he was allowed to be creative. Earlier in his talk, he mentioned that faith is an example of something that is not made of chemicals. Dr. Wilson gave the students an great example of how we can bless others through creativity and intellect.
AP Biology students are running an animal behavior experiment with terrestrial isopods. Students will perform a Chi-Squared analysis to determine whether their isopods have a food preference or whether their “choices” are random.
What do you think the little guys will like best?
The Anatomy & Physiology students are using Maniken Skeletal Models to learn body region names this week. Hands on learning is integral to conceptual understanding, especially in any science course. The class will be building different body systems with clay later this year!
