In this activity, students explore what makes a “good fit” for a protein. They start with an exploration of the differences between small molecules and macromolecules such as proteins. They use cartoon representations to build “protein complexes” in a model and test the effects of shape and temperature on the strength of the fit. Students […]
Explore the structure and function of two of the four major macromolecules: nucleic acids and proteins. It is recommended that you complete the “Introduction to Macromolecules” activity before doing this one.
Explore the structure and function of two of the four major macromolecules: proteins and nucleic acids. This version includes Introduction to Macromolecules.
Given the equation of a quadratic function in vertex form, students learn to identify the vertex of a parabola from the equation, and then graph the parabola. Two different quadratic equations are provided in this activity. Quadratic Functions in Vertex Form is the last of four activities for teaching and learning quadratic equations in algebra: […]
Students solve two problems involving the motion of projectile objects, modeled using quadratic equations. Students graph parabolas and use the graphs to answer questions about projectile objects. Students identify the maximum heights of the moving objects and discover how long each object is in the air before hitting the ground. Quadratic Word Problems Part 1 […]
Students solve two problems modeled by quadratic equations. One problem involves profits from a business and the other, water draining from a bathtub. Students graph quadratic equations and use their graphs to answer questions. Quadratic Word Problems Part 2 is the second of four activities for teaching and learning quadratic equations in algebra: Graphing Quadratic […]
Delve into a microscopic world working with models that show how electron waves can tunnel through certain types of barriers. Learn about the novel devices and apparatuses that have been invented using this concept. Discover how tunneling makes it possible for computers to run faster and for scientists to look more deeply into the microscopic […]
In this activity, you will use a computer model to explore what happens to the Sun’s energy when it strikes Earth.
Measure how fast you can react to three different cues: sight, sound, and touch.
In this activity, you will measure relative humidity in the air using just a temperature sensor, by comparing the wet bulb and dry bulb temperatures.
