General Notes
Laboratory investigations that include the use of scientific inquiry, research, measurement, problem solving, laboratory apparatus and technologies, experimental procedures, and safety procedures are an integral part of this course. The National Science Teachers Association (NSTA) recommends that at the high school level, all students should be in the science lab or field, collecting data every week. School laboratory investigations (labs) are defined by the National Research Council (NRC) as an experience in the laboratory, classroom, or the field that provides students with opportunities to interact directly with natural phenomena or with data collected by others using tools, materials, data collection techniques, and models (NRC, 2006, p. 3). Laboratory investigations in the high school classroom should help all students develop a growing understanding of the complexity and ambiguity of empirical work, as well as the skills to calibrate and troubleshoot equipment used to make observations. Learners should understand measurement error; and have the skills to aggregate, interpret, and present the resulting data (National Research Council, 2006, p.77; NSTA, 2007). Bioscience I is a laboratory based course that focuses on introducing students to the basic lab techniques, equipment, critical thinking, work ethics, and communication skills currently used in the medical, agricultural, marine and industrial bioscience fields. Students will gain an understanding of basic DNA and molecular biology, epigenetics, genetically modified foods, bacterial plasmids, and forensics. Students will learn the principles, methodologies, and applications of equipment such as thermocyclers, horizontal gel electrophoresis apparatus, micropipettes, spectrophotometers, centrifuges, etc. Students will gain proficiency in calculating, preparing, and pH control of common lab reagents, solutions, buffers, and agarose gels. Students will learn the principles of qualitative and quantitative analysis using biomolecular indicators, spectrophotometry, and standard curves. Topics covered will include the genetics of cancer, epigenetics, emerging and re-emerging infectious diseases that affect plants and animals, ethics of bioscience, and careers in bioscience.
Laboratory activities should include but not be limited to:
- Sterilization, handling and safety requirements according to standard operating procedures;
- The preparation of buffer solutions and agarose gels for horizontal electrophoresis;
- The preparation of solutions for spectroscopy;
- Use a spectrophotometer to measure solution concentrations and graph standard curves;
- Bacterial transformation and ligation using the Green fluorescent protein gene;
- Extraction of DNA;
- Quantitative analysis of DNA molecular weights;
- Polymerase chain reactions using given primers;
- Simulate DNA fingerprinting techniques used in crime scene analysis using given gene sequences.
Honors and Advanced Level Course Note: Advanced courses require a greater demand on students through increased academic rigor. Academic rigor is obtained through the application, analysis, evaluation, and creation of complex ideas that are often abstract and multi-faceted. Students are challenged to think and collaborate critically on the content they are learning. Honors level rigor will be achieved by increasing text complexity through text selection, focus on high-level qualitative measures, and complexity of task. Instruction will be structured to give students a deeper understanding of conceptual themes and organization within and across disciplines. Academic rigor is more than simply assigning to students a greater quantity of work.

Lesson Plans
This BLOSSOMS lesson discusses Carbon Dioxide, and its impact on climate change. The main learning objective is for students to become more familiar with human production of Carbon Dioxide gas, as well as to gain an awareness of the potential for this gas to effect the temperature of Earth’s atmosphere. This lesson should take about an hour to complete. In order to complete the lesson, the teacher will need: printed copies of signs representing the different products and processes that take place in the carbon cycle (included), samples of matter that represent those products, handouts for the students to create a graphic of the carbon cycle (included) and graph paper or graphing software for students to create graphs. In the breaks of this BLOSSOMS lesson, students will be creating models of the carbon cycle as well as observing experiments and analyzing data from them. It is hoped that this lesson will familiarize students with ways in which carbon moves through our environment and provide them with some personal connection to the impact that an increased concentration of CO2 can have on air temperature. The goal is to spark their interest and hopefully to encourage them to ask and investigate more questions about the climate.

This is a lesson about phenotypical variation within populations and how these differences are essential for biological evolution. Students will use a model organism (in this case, kidney beans) to explore variation patterns and subsequently connect these differences to artificial & natural selection. The NGSS’ CrossCutting Concepts and Science & Engineering Practices are embedded throughout the lesson.
The main learning objectives are:
- Using a model (kidney beans) to explore the natural variations within a population.
- Measuring differences between individuals in a population (population of beans).
- Describing how genetic/phenotypic variation is a key part of biological evolution because it is a prerequisite for natural selection.
- Demonstrating in which ways genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

This tutorial explores the work of Gregor Mendel and his foundational genetics experiments with pea plants. It provides practice opportunities to check your understanding of inheritance patterns including single gene recessive traits and sex linked traits. The tutorial also covers more complex patterns of inheritance such those resulting from multiple alleles. Note: This resource is part of a larger collection of information regarding Genetics. Users may view information before and after the specific genetics components highlighted here.

Evolution is the process by which modern organisms have descended from ancient ancestors. There are five processes that can lead to evolution within a population. These are Genetic drift, Gene flow, Mutation, Natural selection and Sexual selection. This tutorial will help the learners understand and visualize the way by which these processes affect evolution.

The split brain experiments revealed that the right and the left hemisphere in the brain are good at different things. For instance, the right hemisphere is good at space perception tasks and music while the left is good at verbal and analytic tasks. This game guides students through some examples of the split-brain phenomenon and how the differences are understood.

DNA is the genetic material of all known living organisms and some viruses. DNA contains two stands wrapped around each other in a helix, and these stands are held in place by four chemicals called bases: adenine (A), guanine (G), cytosine (C), and thymine (T). The bases pair up with each other in a specific manner to form units called base pairs - adenine always pairs with thymine, and cytosine always pairs with guanine.
In this game your job is to first make exact copies of a double-stranded DNA molecule by correctly matching base pairs to each strand, and to then determine which organism the DNA belongs to.

This virtual manipulative will help the students to understand that osmosis is the movement of water molecules from an area of high concentration across a semipermeable membrane to an area of low concentration. This illustration of the diffusion process will help the students to understand the concept of osmotic pressure which is created by the movement of the water based on their concentration gradient and thus resulting in the difference of the solute concentration.

In this activity students will recognize that DNA polymerase is responsible for the process of DNA replication, during which a double-stranded DNA molecule is copied into two identical DNA molecules. DNA ploymerase catalyze the polymerization of deoxyribonucleotides alongside a DNA strand, which they read and use as a template. The newly-polymerized molecule is complementary to the template strand.

The genes in DNA encode protein molecules. Expressing a gene means manufacturing its corresponding protein.Translation is the key process of making a protein from the genetic code expresses in the DNA. In translation, messenger RNA is read according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins. This virtual manipulative will allow the students to understand the process of translation. Students will also get a chance to observe, what happens when a new random mutation generates stop codons.

How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution.
Some of the topics to investigate:
- Given acids or bases at the same concentration, demonstrate understanding of acid and base strength by 1. Relating the strength of an acid or base to the extent to which it dissociates in water. 2. Identifying all the molecules and ions that are present in a given acid or base solution. 3. Comparing the relative concentrations of molecules and ions in weak versus strong acid (or base) solutions. 4. Describing the similarities and differences between strong acids and weak acids or strong bases and weak bases.
- Demonstrate understanding of solution concentrated by: 1. Describing the similarities and differences between concentrated and dilute solutions. 2. Comparing the concentrations of all molecules and ions in concentrated versus dilute solutions of a particular acid or base.
- Describe how common tools (pH meter, conductivity, pH paper) help identify whether a solution is an acid or base and strong or weak and concentrated or dilute.

The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Students will explore the effects of mutation within the lac operon by adding or removing genes from the DNA.
- Predicts the effects on lactose metabolism when the various genes and DNA control elements are mutated (added or removed).
- Predicts the effects on lactose metabolism when the concentration of lactose is changed.
- Explain the roles of Lacl, LacZ, and LacY in lactose regulation.

Students can test the pH of several substances and visualize hydronium, hydroxide, and water molecules in solution by concentration or the number of molecules. Students can add water to a given substance to see the effects it will have on the pH of that substance; or they can create their own custom substance.

This is a simplified, interactive demonstration of genetic principles. Using a fictional species named the Norn, students can predict the outcome of genetic crosses (mono and di-hybrid, sex-linked, and multiple-allele). This could be used to strengthen the students understanding of genetics, practice Punnet squares, or practice calculation of genotypic/phenotypic ratios. However, it is unlikely to be useful as an independent assignment (if used as designed).

This interactive cell membrane simulation allows students to see how different types of channels allow particles to move through the membrane.
Sample learning goals:
- Predict when particles will move through the membrane and when they will not.
- Identify which particle type will diffuse depending on which type of channels are present.
- Predict the rate of diffusion based on the number and type of channels present.
