Building Proteins: How Do Cells Read the Blueprint?

How is the information stored in DNA used to build proteins in our cells? Participants will use hands-on, minds-on manipulatives to verbalize their thought processes as they use a DNA template to create RNA, then “read” the codons on the mRNA to build a protein at the ribosome.

7:30-8:30 AM Omni Sundance 6

Dynamic DNA: Exploring DNA Structure and Function as an Information Storage Molecule 

DNA can be modeled either as a macromolecule or as a source of information. Participants will explore both features of DNA with an interactive DNA model and a paper bioinformatics exercise focusing on the beta subunit of hemoglobin. Participants will identify the point mutation that leads to sickle cell disease.

Diving into Water! Exploring Water Properties in Biology and Chemistry 

Polar water molecules are the driving force for many mechanisms in biology and chemistry. This hand-on session with interactive models explores the chemical underpinnings of the properties of water that will assist in introducing chemical principles in biology and enriching chemistry courses with biological applications.

1:30-2:30 PM Omni Sundance 3

Constructing and Crossing Cell Membranes

Why is the cell membrane structure a bilayer? A series of hands-on/minds-on thought experiments will lead students to a foundational understanding of the composition of the cell membrane. Find out how proteins play an important role in active and passive transport of materials across the membrane.

Science Olympiad: Tips for Success in the Protein Modeling Event

The theme for this year’s Science Olympiad Protein Modeling Event focuses genome editing using CRISPR-Cas9. This session will introduce a variety of resources available to explore the topic and provide insights for preparing a team for a successful competition. Materials are also suitable for classroom use in exploring this topic.

9:30-10:30 AM Omni Fort Worth 1-3 

Using Models to Uncover Student Misconceptions in Chemistry 

The molecular world of chemistry is difficult for many high school students to grasp.  Discover how students’ conceptual understanding of atoms, molecules, compounds, and elements can be uncovered using modeling.  Explore chemistry topics in polarity, density, solubility, bonding, and much more with hands-on, minds-on manipulatives!

Enzymes in Action 

Enzymes are specialized biomolecules that play an important role in biological processes. The sequence of amino acids along with the basic principles of chemistry influence an enzyme’s final three-dimensional shape and ultimately its function. Analysis of changes in enzyme structure reveal a significant impact on catabolic and anabolic reactions.
