Honors Honors Program in the School of Biological Sciences The Honors Program in the School of Biological Sciences provides an opportunity for outstanding majors in the School to pursue advanced work in independent research via participation in the Excellence in Biological Sciences Research Program and earn Honors in Biological Sciences upon graduation. Additionally, students must have a minimum overall 3. Graduation with Honors Of the graduating seniors, no more than 16 percent will receive Latin honors: The selection for these awards is based on spring quarter rank-ordered grade point averages.

Ideally, a teacher would have no more than twenty four students to coach through this activity. A student will have prior knowledge as to the equation describing the photosynthetic process as well as having a basic understanding of the scientific method.

The lab could be used in a unit on, the scientific method, a photosynthetic unit or in a unit on environmental problems global climate change and its affect on plants. Teacher and students will review the equation describing photosynthesis.

What types of organisms undergo photosynthesis?

Discussion will include the ideas that not all plants photosynthesize at the same rate. Brainstorming will bring out possible reasons and variables that would influence photosynthesis.

Leaf structures will be named and discussion will relate these structures to the processes of photosynthesis that occur in each. This would be the time to give examples of how some questions scientists raise are not testable. Students should be thinking about the question they will raise about the photosynthesis experiment and if an investigation can be designed to test their question.

The teacher can now review what a hypothesis is and how to write a specific, testable hypothesis. Basic Materials needed for lab group of students: The teacher will now demonstrate to students the basic technique that will be used to measure the rate of photosynthesis.

Designing an experiment to test the rate of photosynthesis

All students will be guided to use this technique. They can now practice this technique see experimental design and the following web site http: Pick a testable question to answer when doing the experiment.

Give students time to design experiment and do a trial run. Class discussion will connect the lab to world issues; food availability, global climate change. Teaching Notes and Tips 1 Use fresh spinach leaves, soak them in water overnight at about 4 degrees C. This increases turgor pressure and minimizes "limp" leaves.

Use only the firm, dark green areas of the leaf. Avoid major veins or damaged areas. Too little vacuum treatment causes the disks not to sink, too much vacuum treatment may kill the cells. Assessment Two rubrics will be used to assess student lab report sample of report included below and student participation.

A written exam will be used to determine if a student has met the goals of the activity. Where in a leaf does photosynthesis mainly occur?

How does carbon dioxide get into a leaf? How does water get into a leaf from the roots? Obtain a prepared slide of a leaf cross section x-section. Using x make a sketch of what you see.

Use the text book or internet to label the following tissues; Upper epidermis, lower epidermis, palisade mesophyll, spongy mesophyll, vein label both xylem and phloemguard cells, stoma 1 In which of the labeled structures, does most of the photosynthesis occur? Write out a balanced equation for photosynthesis:“When teaching about the immune response, I use the Immunology Virtual Lab to expose my students to a common laboratory assay, the ELISA (enzyme-linked immunosorbent assay), which detects the presence of a particular antibody in the blood of an individual.

Starting with some self study activities students begin to learn the names and features of the four plant phyla required for IB. Using micro-organisms in IB Bio labs. The FIFA World Cup was the 21st FIFA World Cup, an international football tournament contested by the men's national teams of the member associations of FIFA once every four years.

It took place in Russia from 14 June to 15 July It was the first World Cup to be held in Eastern Europe, and the 11th time that it had been held in Europe. At an estimated cost of over $ billion, it.
