Radioactive Decay, Ryan Case, Jayson Pritchard Jun 2016

Radioactive Decay, Ryan Case, Jayson Pritchard

Lesson Plans

The purpose of this model is to simulate the decay of radioactive nuclei to the stable isotope Lead-206. First and foremost, the model is designed to illustrate the concept of a half-life, which is the amount of time it takes for half a given quality of nuclei to decay to the next nuclei. In addition it also demonstrates that different radioisotopes have different half-lives than one another, and that the mass is conserved in nuclear reactions but not necessarily the number of protons, neutrons, or nuclei.


Insolation And Ecosystem, Margaret Allocco, Chris Haller Jun 2016

Insolation And Ecosystem, Margaret Allocco, Chris Haller

Lesson Plans

The purpose of this model is to demonstrate the impact of angle of insolation and precipitation on the health of a specific climate zone’s ecosystem


Exploring Density, Jamye Babocsi, Agnieszka Wallace Jun 2016

Exploring Density, Jamye Babocsi, Agnieszka Wallace

Lesson Plans

This density model is designed to allow students to explore how mass, volume, and temperature directly affect the density of an object or liquid


Biomagnification And Bioaccumulation, Grace Linder, Lauren Thresh Jun 2016

Biomagnification And Bioaccumulation, Grace Linder, Lauren Thresh

Lesson Plans

This computational model is intended to demonstrate how micropollutants effect ecology via the living environment concepts of biomagnification and bioaccumulation. Specifically, this model shows how concentrations of a micropollutant change throughout an aquatic food chain.


Chemical Weathering, Elizabeth Kreppel, Kaitlin Ordiway Jun 2016

Chemical Weathering, Elizabeth Kreppel, Kaitlin Ordiway

Lesson Plans

This model shows the effects of acid rain on different rock types.


Carbon Emissions, Breanna Hummel, Samantha Slossar Jun 2016

Carbon Emissions, Breanna Hummel, Samantha Slossar

Lesson Plans

This model demonstrates how a population affects the carbon emissions in a region.


Osmosis And Plasmolysis, Andy Bumstead, Anthony Raymond Jun 2016

Osmosis And Plasmolysis, Andy Bumstead, Anthony Raymond

Lesson Plans

This model simulates the processes of diffusion and osmosis in a plant cell


Firework Show, Kaitlin A. Ordiway, Miranda Wharram, Steven Lauffer Jun 2015

Firework Show, Kaitlin A. Ordiway, Miranda Wharram, Steven Lauffer

Lesson Plans

Our model allows student to create a firework show in order to distract zombies long enough to get food and get back to their home base. Students will use their knowledge of emission, light and energy to determine the best firework show possible.


Molecular Collisions, Kaitlin A. Ordiway, Miranda Wharram, Steven Lauffer Jun 2015

Molecular Collisions, Kaitlin A. Ordiway, Miranda Wharram, Steven Lauffer

Lesson Plans

Our model is designed to simulate molecular collisions and prompt students to question the factors affecting collisions. It brings together chemistry, physics, and mathematics. Through the sliders and monitors on our interface page, students will be able to observe as well as manipulate the factors that affect inelastic collisions between two different molecules. Using the known kinetic energy equations and the velocity found from the frames per second, students will be able to calculate the distance traveled.


Particle Transport, Samantha Slossar, Jamye Babocsi, Chuck Ko Jun 2015

Particle Transport, Samantha Slossar, Jamye Babocsi, Chuck Ko

Lesson Plans

The particle transport simulation is designed to help students gain a deeper level of understanding of the relationship between velocity and particle size. Students will be able to manipulate the velocity and particle size to see if the particle will move. The mathematical component will require the students to construct a particle graph using the simulator and Earth Science Reference Table (ESRT).


Sickle Cell Anemia, Joshua Dubay, David Krebs, Lauren Thresh Jan 2015

Sickle Cell Anemia, Joshua Dubay, David Krebs, Lauren Thresh

Lesson Plans

What is Sickle Cell Anemia?

The purpose of this model is to deepen student understanding of the human body through investigating the structure and function of red blood cells in the human circulatory system. The students will compare and contrast structure and function between normal red blood cells and sickle blood cells and will learn how disruptions in one body system can disrupt homeostasis in other body systems (conditions of stability and determinants of change). Students will engage in mathematics to support their observations and inferences founded within the simulation. Data will be collected to construct linear graphs and build ...


Tooth Enamel, Joshua Dubay, Lauren Thresh, David Kreb Jan 2015

Tooth Enamel, Joshua Dubay, Lauren Thresh, David Kreb

Lesson Plans

The purpose of this model is to demonstrate the natural phenomena of acid molecules eroding the enamel of an individuals tooth. Through this lesson students will identify pH levels of common acidic foods and drinks. Student will also determine the significance of saliva to the maintenance of pH of the mouth. Students will discover that the longer acidic molecules are exposed to the enamel of a tooth the percentage of healthy enamel on a tooth decreases. When healthy enamel is eroded, dentin is exposed, which gives teeth a yellow appearance. Students will use the model to compare the relation of ...
