Authentic Ecological Inquiries Using BearCam ArchivesLearning ObjectivesStudents will be able to:
- conduct an authentic ecological inquiry including
- generate a testable hypothesis based on observations,
- design investigation with appropriate sampling selection and variables,
- collect and analyze data following the design, and
- interpret results and draw conclusions based on the evidence.
- write a research report with appropriate structure and style.
- evaluate the quality of inquiry reports using a rubric.
- conduct peer review to evaluate and provide feedback to others' work.
- revise the inquiry report based on peer feedback and self-assessment.
- conduct an authentic ecological inquiry including
Teaching Genetic Linkage and Recombination through Mapping with Molecular MarkersLearning ObjectivesStudents will be able to:
- Explain how recombination can lead to new combinations of linked alleles.
- Explain how molecular markers (such as microsatellites) can be used to map the location of genes/loci, including what crosses would be informative and why.
- Explain how banding patterns on an electrophoresis gel represent the segregation of alleles during meiosis.
- Predict how recombination frequency between two linked loci affects the genotype frequencies of the products of meiosis compared to loci that are unlinked (or very tightly linked).
- Analyze data from a cross (phenotypes and/or genotypes) to determine if the cross involves linked genes.
- Calculate the map distance between linked genes using data from genetic crosses, such as gel electrophoresis banding patterns.
- Justify conclusions about genetic linkage by describing the information in the data that allows you to determine genes are linked.
Knowing your own: A classroom case study using the scientific method to investigate how birds learn to recognize their...Learning Objectives
- Students will be able to identify and describe the steps of the scientific method.
- Students will be able to develop hypotheses and predictions.
- Students will be able to construct and interpret bar graphs based on data and predictions.
- Students will be able to draw conclusions from data presented in graphical form.
What do Bone and Silly Putty® have in Common?: A Lesson on Bone ViscoelasticityLearning Objectives
- Students will be able to explain how the anatomical structure of long bones relates to their function.
- Students will be able to define viscoelasticity, hysteresis, anisotropy, stiffness, strength, ductility, and toughness.
- Students will be able to identify the elastic and plastic regions of a stress-strain curve. They will be able to correlate each phase of the stress-strain curve with physical changes to bone.
- Students will be able to predict how a bone would respond to changes in the magnitude of an applied force, and to variations in the speed or angle at which a force is applied.
- Students will be able to determine the reason(s) why bone injuries occur more frequently during athletic events than during normal everyday use.

- Identify the effect of nutrients on the growth of photosynthetic organisms.
- Describe global cycles in atmospheric carbon dioxide levels and how they relate to photosynthetic organisms.
An active-learning lesson that targets student understanding of population growth in ecologyLearning ObjectivesStudents will be able to:
- Calculate and compare population density and abundance.
- Identify whether a growth curve describes exponential, linear, and/or logistic growth.
- Describe and calculate a population's growth rate using linear, exponential, and logistic models.
- Explain the influence of carrying capacity and population density on growth rate.
