Neuroscience

Over the course of the year in Neuroscience, we explore the following essential questions: How do scientists go about solving problems related to the brain? How do we process data to extract meaning? How does the brain store and retrieve memories? How does the brain detect and respond to changes in the environment? How do attention, emotion, memory, and the senses impact one another?

Research: 

Students explore the nature of science through primary literature, using a variety of tools to guide themselves through their analysis of journal articles. Students are expected to access and interpret background information, decipher figures and interpret findings in order to gain deeper understanding of a topic in neuroscience or psychology shaped by their own interests. After conducting in-depth research using academic databases and reading extensive material related to their topic, students design controlled experiments to test it. During this process, students write an Introduction and References that emulates professional manuscripts. In this writing, students are expected to describe the prior knowledge that led to their investigation and hypothesis and provide background information to highlight the importance of their study. While completing their investigation, students write the Methods, Results and Discussion components of their paper.

Microbiology

Students may think of microbes -- sometimes called germs -- as something they want to wash off carefully or just avoid completely. But some microbes feed us, recycle our trash, or even keep us healthy! In this class students grow microbes on purpose, and conduct experiments about our tiniest living neighbors. Required background research and lab reports are important parts of this course.

Interim Assessments: 

Presentations are the most important interim assessment. Both the presenter and the respondents are expected to participate at high levels of cognitive engagement. This gives a very clear diagnostic of student thinking about microbes, texts, and experimental research.

Other assessments include early drafts of lab report sections, the first entire lab report, and other written assignments including the class notebook. Students are expected to take notes on what they do and learn in every class period. This is largely a laboratory notebook, but also records their thinking on broader issues.

Significant Assignments:

Sample PBATs: 
How does ultraviolet light affect the survival of pigmented bacteria collected from the classroom environment??
How does the type of hot sauce affect the diameter of the zone of inhibition in Staphylococcus epidermidis
How does calcium propionate affect the colony diameter of Penicillium roqueforti grown on a bread-agar medium?

Mix it Up!

Is whipped cream a solid, a liquid, or a gas? What about jam or jello? Oil and water don't mix, right, so how is it possible that mayonnaise is mostly oil and water? How come sugar sinks to the bottom of your iced tea but seems to disappear if the tea is hot? In this hands-on science class, students investigate the chemistry of kitchen mixtures like these. They develop their own experimental questions, conduct experiments, do background reading, and write up their findings.

Research: 

Starting with the question: What is the best way to make exactly one cup of simple syrup, if you have to use one part sugar to one part water?, the students begin their study of dissolution and the properties of different kitchen solutes, solvents, and solutions, including colligative properties. Next we examine crystalline versus amorphous structure in solids, usually through an experiment involving rock candy. Finally we examine colloids, beginning with vinaigrette and then mayonnaise. Final projects vary but always involve student-developed experiments on the chemistry of kitchen mixtures.

Interim Assessments: 

The first lab report functions as the first interim assessment. Depending on the semester, the topic may be solutions or crystalline and amorphous structure in solids. This may be done class-wide, in small groups, or individually.

The final lab report functions as Interim Assessment 4. Each student develops an individual experiment based on background research about a topic related to kitchen colloids. Students present their work to the class and lead a short discussion.

Significant Assignments: 

Research culminating in a literature-inspired experimental question, an introduction presenting relevant background information, and a hypothesis that addresses the literature. (This is assigned at least two different times each semester).

Individual or small-group presentations. These take place at different stages of the process of developing and conducting an experiment. Students are expected to share what they know, identify areas that need more work, and then respond to feedback and suggestions from the class.

Experimental designs. Students must develop procedures for testing specific hypotheses.

Analysis. Students must analyze the results of their experiments. They also critique the experimental design, and suggest possible follow-up investigations.

Physics is the study of forces and motion. In this course we will use equations to describe the motion of objects, from the sudden stop of an express A-train to the arc of a home run. We will begin by describing (mathematically and graphically) the motion of objects moving in only one dimension, and then discuss the fundamental concepts of force, energy, and torque.

Readings: 
Conceptual Physics - Paul Hewitt
Research: 

PBAT Design & Research Guide
For your PBAT experiment, you will make a series of modifications to your race car and measure the effect these modifications have on your race car’s performance. This guide will help you design your experiment and begin to write the first key sections of your PBAT.

Modifications:
In your experiment, you can either measure the effect of one modification, or compare the effect of two different modifications. The following are some examples of possible modifications:
Increase / decrease mass
Change length of lever arm
Increase / decrease wheel size
Increase traction on wheels
Move location of mousetrap
Change wheel design
Change wheel mass
Change wheel to axle ratio

You can choose from any the modifications listed above, or another modification you propose. Your modification must be incremental (you can gradually increase the modification) and reversible (you can undo the modification). For example, if you modify the length of the lever arm, you must perform tests using a series of different lengths, and you must be able to go back to your original length. All modifications must be approved by Paul.

Research & Hypothesis:
The research section of your paper will serve two functions. First, you will describe how your unmodified racecar (your Control) works, including any relevant physics. You will then describe the physics concepts behind your modification(s). The concepts will depend on your chosen modification(s), but will likely include: Newton’s Laws, rotational motion, torque, friction, etc. Once you have chosen your modifications, you should read the relevant chapters in the textbook. Your research section should be ~2 pages in length.
After you have presented your research, you will present your hypothesis. Your hypothesis will be a specific prediction about the outcome of your experiment that is grounded in your research. Your prediction must be specific as possible so that you can determine the accuracy of your data. Your research should give you some idea of how great the effect of your modification will be --you may not simply say that your car will go faster or farther, your prediction must be quantitative. Example: Because of the relationship between wheel diameter and velocity, we predict that, by doubling the radius of the drive wheels, the final velocity of the car will double.

Procedure:
Your procedure should be a detailed description of how you will perform the experiment. You must identify the controls and variables and describe the significance of each. You must also include a complete step-by-step set of instructions for performing your experiment, describing how you collect data for each trial. What quantities will you measure? How many data points will you take? How many trials will you run? You must also identify potential sources of error and describe how your procedure will minimize the effect of these errors.
Rule of thumb: Someone outside of your group should be able to repeat your experiment using your procedure and get similar results. This means that your procedure should contain all the relevant instructions and details needed to successfully perform your experiment.
Your procedure should be ~2 pages in length.

Data Collection:
For this proposal you should include the data table you plan on using for your experiment. Although you will not need to include a blank data table in your final PBAT, this will help you as you write your procedure.

Media Used:

Significant Assignments: 

Students must submit a proposal for the experiment they wish to perform using their race-car.

Sample PBATs: 
How does the length of the mousetrap lever-arm affect the acceleration of the race car?
How does the traction of the wheels affect the speed of the race car?
How does the size of the axle affect the speed of the race car?
What is the relationship between the mass of the drive wheels and the final speed of the race car?

Interim Assessments: 

Using authentic, 150-million year old dinosaur fossils, students are required to determine the kind of environment the bone was deposited and then compare that environment to the environment where the bone was quarried. This task is accomplished through the systematic observation and testing of the size and characteristic properties of the matrix rock surrounding the fossil. Students make inferences about the paleoenvironment of the fossil deposition and compare this with the environment of the fossil quarry. In addition to their research on the fossils, students clean, repair and restore the fossils as a service to the organization that has allowed us to use the materials.

An honors extension of this class is participation in a non-fiction literature circle that uses the book "Under a Green Sky" to focus on the "Big Five" mass extinctions in Earth's history and understanding the leading hypotheses about the causes of each.

Significant Assignments: 

All classwork and labs are included in the three class journals. These labs include a rock identification lab, river flow model lab, fossil identification lab, a series of labs concerning foraminifera, and finally a lab creating a to-scale model of geologic time.

Sample PBATs: 
In what environment was this dinosaur bone deposited and how does this environment compare to the environment where the dinosaur bone was quarried?
Are the Morrison Formation's sediments biogenic or abiogenic?
How can fossils be used to determine how environments have changed over time?

Science of DaVinci

Leonardo Da Vinci exemplified the Renaissance Man. He was an "anatomist, botanist, geometer, physicist, architect, mechanical engineer, hydraulic engineer, civil engineer and even aeronautical engineer. Oh, and he also painted a little. Much of his success was due to his incredible skills of observation and his devotion to collecting and analyzing data. In a time when many scientists tried to "see" what they had been told was true, he found truth in what he actually saw.

Research: 

The students study force and drag created by air resistance in order to make predictions about the fall of the parachutes. We go on to look at floating and buoyancy. For the final project, the topics covered vary. Students have looked at people's responses to rectangles drawn using the golden ratio, how blue shading affects the perception of depth, the effect of shape on acoustics, mirror-writing and mirror-reading, as well as more motion-based topics involving trebuchets and crossbows.

Interim Assessments: 

The first lab report fills the requirements of the first interim assessment. Students make predictions about how the size and shape of a parachute would affect the speed of its fall. The whole class has to then agree on a method of dropping the parachutes and collecting data. Each student has to analyze the class data and write his/her own report.

The third lab report fulfills the requirements for Interim Assessment 4. Each student develops an individual experiment based on background research about a topic suggested by Leonardo's work. Students are required to perform a descriptive statistical analysis of their data using a standard deviation. Each student has to present his or her work to the class and lead a short discussion of the work.

Significant Assignments: 

Three laboratory reports. The experiments all come from a subject suggested by Leonardo's work. The first on a full-class parachute project. The second on a small-group assignment on the development of, science behind, and testing of water shoes. The third laboratory report based on an individual project of the student's choosing.

Sample PBATs: 
How does the ratio between the sides of a parachute with a rectangular profile affect the time and drift of its fall?
How does the level of blue in an image affect the perception of depth?
How does the type of scoop affect a trebuchet?
How does the stopping point of the arm affect a trebuchet?
