Dynamic Daphnia: An inquiry-based research experience in ecology that teaches the scientific process to first-year...Learning ObjectivesStudents will be able to:
- Construct written predictions about 1 factor experiments.
- Interpret simple (2 variables) figures.
- Construct simple (2 variables) figures from data.
- Design simple 1 factor experiments with appropriate controls.
- Demonstrate proper use of standard laboratory items, including a two-stop pipette, stereomicroscope, and laboratory notebook.
- Calculate means and standard deviations.
- Given some scaffolding (instructions), select the correct statistical test for a data set, be able to run a t-test, ANOVA, chi-squared test, and linear regression in Microsoft Excel, and be able to correctly interpret their results.
- Construct and present a scientific poster.
The Science Behind the ACTN3 PolymorphismLearning ObjectivesThis article accompanies the lesson "The ACTN3 Polymorphism: Applications in Genetics and Physiology Teaching Laboratories." Learning objectives for the lesson include:
- Test hypotheses related to the role of ACTN3 in skeletal muscle function.
- Explain how polymorphic variants of the ACTN3 gene affect protein structure and function.
- List and explain the differences between fast twitch and slow twitch muscle fibers.
- List and explain possible roles of the ACTN3 protein in skeletal muscle function.
- Find and analyze relevant scientific publications about the relationship between ACTN3 genotype and muscle function.
- Formulate hypotheses related to the relationship between ACTN3 genotype and skeletal muscle function.
- Design experiments to test hypotheses about the role of ACTN3 in skeletal muscle function.
- Statistically analyze experimental results using relevant software.
- Present experimental results in writing.
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.

- Geographically map organisms using smartphones and an online mapping program
- Calculate metrics of species diversity using spreadsheet software
- Use spreadsheet software to quantify and graph biodiversity at forest edges vs. interiors
- Write a formal lab report
- Extract, amplify, visualize and sequence DNA using standard molecular techniques (PCR, gel electrophoresis, Sanger sequencing)
