Beaches

What is the fate of our beaches - a truly transitional habitat? How do
tides, waves and ocean currents influence that shape of our beaches?
Who has the right to change the shape of our beaches? Scientists?
Politicians? Landowners? How will these changes influence the life on
the beach and the seafood many people love to eat? This PBAT course
will investigate sand, surf, and sea life, while bringing to light the
debate about beach restoration.

The topics for the course are;
• UNIT 1: What is a beach, how is it formed, and what influences it?

Significant Assignments: 

Concept maps are used to interpret information from four different science texts. Concept maps are widely used in research science to effectively illustrate and communicate scientific processes, ideas, and scientific models. Students we learn how to develop a successful concept map based on one of the natural influences that shape shorelines. The concept map practice will aid students in understanding the significance of the topic and its application in designing a successful lab investigation.

The end product of the first unit is a wall-sized mural composed of the 9 different group concept maps, which are, in turn, designed by 3 different students. Linking text between topics will encourage analysis of the information from the concept maps of others. A major component of this unit is peer evaluation and critique, where we often refer back to each others work as we strive to design more effective means of communicating the topic.

The second unit will focus on the specific characteristics of geographically isolated beach communities. Students will take on the task of reporting on the types of sand, slopes, structures, and life that occupy that land boundary.

Research: 

Rock and mineral characteristics and composition are often used to characterize an abiotic environment. By examining types of minerals and the presence of those minerals in various types of rocks, we can better make predictions about the influence of that rock type on beach erosion. Rocks like sand stone and granite will result in different beach composition than rocks likes basalt and pumice.

In this first unit, it is important to evaluate skills of objective observation, such as measurement of length, volume, mass, and density, while also creating a forum for more subjective observations such as color, luster, and texture. Students will make predictions of the effect these characteristics will have on sand density, sand particle size, and ultimately sand displacement in water currents. Students will also predict the effect that specific beach structures will have on wave patterns and erosion by physically creating models of these structures on a beach and watching the effect of the waves on the shape of the structure.

The second unit will focus on the biotic characteristics of the beaches. Comparisons will be made between different beach structures, sand compositions and the links to the flora and fauna related to those habitats. Can we see distinct patterns between organisms and the geologic features at each habitat? Which of the geological characteristics have a more obvious influence on the life present?

Sample PBATs: 
How does particle size influence the erosion of beach sand?
Does sand density influence the erosion of beaches?
How does sand movement affect the interstitial beach community?
What are the alternatives to beach replenishment?
How is salinity influenced by rock composition?

Advanced Biology

In this yearlong Advanced Biology course, students will learn the foundations of biotechnology. The course begins with a review of cellular biology focusing on molecular genetics. Students will conduct experiments such as DNA extraction, DNA fingerprinting, bacterial transformation, DNA analysis using gene chip and mitochondrial DNA sequencing. Students will conduct background research for the labs by reading scientific articles and other primary and secondary sources.

Readings:

Significant Activities or Projects: 

• DNA Extractions – Students learn techniques for extracting DNA from cheek cells, wheat germ, strawberries, and other organic substances.

• Bacterial Transformation – Students will genetically engineer the E.coli bacteria to uptake genes for antibiotic resistance and bioluminescence.

• Forensic DNA Profiling – Students will examine the variable tandem repeat polymorphism. They will amplify the polymorphic locus and use a DNA chip to determine their genotype. Students will also use population genetics to calculate the frequency of their genotype.

• Mitochondrial DNA Sequencing – Students will isolate, amplify, and sequence a small region of their mitochondrial DNA. They will then compare their sequence to their classmates (who are all recent immigrants from around the world).

Sample PBATs: 
Mitochondrial DNA Project: Students will conduct background research on the origin of modern humans, exploring both the Multi-Regional and Out of Africa theories. Students will use this information to form a hypothesis about which students in the class will be most closely related. They will then analyze their mitochondrial DNA sequences to determine if the data supports their hypothesis. Students will submit a written lab report and defend their results orally to a panel of students, teachers and external evaluators.

Da Vinci Art and Science

This course has students look at Leonardo da Vinci from the perspective of art and science. Students will take two classes; each cycle will focus on a different aspect of da Vinci’s life and work.

In the Cooking Chemistry projects students will write their own recipe and point out various places in that recipe where Chemistry is involved. Students will explain the process of producing the heat needed to cook their meal as well as the changes that are going on to their food as it is heated and cooked. Students will also focus on current research in the area to identify possible health benefits or risks associated with eating components of that meal.

Students will also complete a Rube Goldberg project where they will plan a Rube Goldberg apparatus. To successfully complete this project students will have to bring in their knowledge of molecules, bonding, balancing chemical equations, stoichiometry, and basic electronics.

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.
