2. N EW C URRICULUM Focus on 4 Big Ideas in Biology 1. The process of evolution drives the diversity and unity of life 2. Biological Systems utilize free energy and molecular building blocks to grow, to reproduce, and to maintain dynamic homeostasis 3. Living systems store, retrieve, transmit and respond to information essential to life processes 4. Biological systems interact, and these systems and their interactions possess complex properties

3. N EW C URRICULUM Focus on 7 science practices 1. The student can use representations and models to communicate scientific phenomena and solve scientific problems 2. The student can use mathematics appropriately 3. The student can engage in scientific questioning to extend thinking or to guide investigations within the context of the AP course 4. The student can plan and implement data collection strategies appropriate to a particular scientific question

4. N EW C URRICULUM Science practices continued…. 5. The student can perform data analysis and evaluation of evidence 6. The student can work with scientific explanations and theories 7. The student is able to connect and relate knowledge across various scales, concepts, and representations in and across domains

5. N EW C URRICULUM Focus on Inquiry Laboratory Experiences 25% of the class is required to be spent in lab Many labs have multiple components, one of which will be inquiry Required to do a minimum of two AP bio labs per Big Idea

6. L ABORATORY E XPERIENCE Work in small groups of 2 to 4 people Each person is required to have a Lab Log book (can be purchased at Staples for $1 or use the one I provide) Information reported via log book, lab report, and/or mini poster

11. N EW M ULTIPLE C HOICE S TYLE Section 1 Example : By discharging electric sparks into a laboratory chamber atmosphere that consisted of water vapor, hydrogen gas, methane, and ammonia, Stanley Miller obtained data that showed that a number of organic molecules, including many amino acids, could be synthesized. Miller was attempting to model early Earth conditions as understood in the 1950s. The results of Miller’s experiments best support which of the following hypotheses? (A) The molecules essential to life today did not exist at the time Earth was first formed. (B) The molecules essential to life today could not have been carried to the primordial Earth by a comet or meteorite. (C) The molecules essential to life today could have formed under early Earth conditions. (D) The molecules essential to life today were initially self- replicating proteins that were synthesized approximately four billion years ago

12. N EW M ATH Q UESTIONS Section 2 Example : In a certain species of flowering plant, the purple allele P is dominant to the yellow allele p. A student performed a cross between a purple-flowered plant and a yellow-flowered plant. When planted, the 146 seeds that were produced from the cross matured into 87 plants with purple flowers and 59 plants with yellow flowers. Calculate the chi-squared value for the null hypothesis that the purple-flowered parent was heterozygous for the flower-color gene. Give your answer to the nearest tenth.

13. 10 POINT F REE R ESPONSE Plants lose water from their aboveground surfaces in the process of transpiration. Most of this water is lost from stomata, microscopic openings in the leaves. Excess water loss can have a negative effect on the growth, development, and reproduction of a plant. Severe water loss can be fatal. Environmental factors have a major impact on the rate of plant transpiration. TRANSPIRATION RATE VERSUS TEMPERATURE Temperature (°C) 20 23 27 28 Transpiration rate (mmol/m2 sec)1.5 3 5 4.5 (a) Using the data above and the axes provided, draw a graph showing the effect of temperature change on the rate of transpiration. Explain the shape of the curve from 23 degrees to 28 degrees. (b) Humidity is an environmental factor that affects transpiration rate. Using the axes provided, draw a curve that illustrates what you predict would be the rate of transpiration with increasing humidity and constant temperature. Justify the shape of the curve based on your prediction. (c) The curve below illustrates the rate of transpiration related to the percent of open stomata on the leaf of a particular plant. Explain why the curve levels off with increasing percentage of open stomata per area of the leaf. (Graph would be present on actual test) (d) The data below show the density of stomata on the leaf surfaces of three different species of plants. Describe the environments in which each plant most likely evolved. Justify your Descriptions. Stomata Density (# of stomata/mm2) PlantIn Upper EpidermisIn Lower Epidermis Anacharis 0 0 Water lily 420 0 Black walnut 0 465

14. 3 TO 4 POINT F REE R ESPONSE Populations of a plant species have been found growing in the mountains at altitudes above 2,500 meters. Populations of a plant that appears similar, with slight differences, have been found in the same mountains at altitudes below 2,300 meters. (a) Describe TWO kinds of data that could be collected to provide a direct answer to the question, do the populations growing above 2,500 meters and the populations growing below 2,300 meters represent a single species? (b) Explain how the data you suggested in part (a) would provide a direct answer to the question.
