Goal: Provide teachers with classroom ready spreadsheet modeling activities, "Spreadsheet Labs," that unite Science and Math to model real world phenomena using Excel or Google spreadsheets. "The Spreadsheet Lab Manual" laboratory suite consists of 25 independent spreadsheet based simulations in high school Physics, Chemistry, Biology and Math.
STEM MAJORS NEED SPREADSHEETS all the time, the spreadsheet is the go-to program for any task involving data collection and analysis. On top of this the skills transfer across operating systems. Proficiency on a spreadsheet will help bridge the skill gap that separates students who are successful STEM majors and students changing out of STEM to a different major in college. The Spreadsheet Lab Manual simultaneously give students command of math and teaches them to reason quantitatively on a platform (the spreadsheet) that has become a standardized part of both higher education and industry.
Scroll Down to View Graphs and Activity Summaries: The following graphs are produced and manipulated by students completing the activities in The Spreadsheet Lab Manual*. The data is generated from mathematical models written and assembled by the students by following the procedures outlined in the activities.
Activity: "Comparing Trajectories" (Physics) click to view: Video Demonstration
Description: This graph compares the trajectories of projectiles with and without air resistance on a spreadsheet. Students can investigate this motion by adjusting cross sectional area, mass, initial velocity, launch angle or drag coefficient and immediately observing the effect of the change.
Content Areas: Kinematics, Forces and Newton's Laws
Objectives: Students will create a spreadsheet from scratch that quantitatively calculates the trajectory of a projectile and then answer questions that will allow them to model a wide variety of projectiles experiencing drag force.
Activity: Taken from "Acid Base Titration" (Chemistry) click to follow: Video Demonstration
Description: This graph is produced by students simulating titration of an acid with a base of known concentration using logical and problem solving functions on a spreadsheet.
Content Areas: Acid Base Chemistry, Analytical Methods
Objectives: The students will simulate titration, perform titration calculations by solving problems with spreadsheet functions (goal seek), and explain why students often over titrate in a lab due by quantitatively observing the small volume required for neutralization.
Activity: Taken from "Population Growth 2*" (Predator Prey Simulation) (Biology)
Description: This is a graph of the populations of predator and prey populations approaching equilibrium numbers as their linked populations cycle based on their interdependence. Content Area: Ecology, Population Dynamics
Objectives: The students will observe the dynamics of a predator and prey species and conditions that lead to extinction by constructing a mathematical model of their populations and graphing them verses time on spreadsheet. The students will alter variables such as initial populations, predator benefit, prey fatality probability, logistic competition factors, minimum viable populations.
* Serves as a follow-up to "Population Growth 1" which compares Ideal and Logistic Models.
Activity: "The Superposition Principle" (Physics) Video Demonstration
Description: Superimposing wave functions with equal amplitudes and nearly equal frequencies to produce beats on a spreadsheet.
Content Area: Wave Mechanics
Objectives: The students investigate how the superposition principle can cause wave amplitudes to combine for waves both in phase and out of phase. Beats are observed at multiple different frequency combinations to study the effect of varying frequency and amplitude to infer a model for the phenomena of beats.

The Spreadsheet Lab Manual is a collection of Science and Math activities each of which begins by opening a blank spreadsheet and following the instructions to construct a spreadsheet that performs a relevant task. The tasks range from simulations of physical behavior (such as the above examples) that can be modeled mathematically to solving a multiple step mathematical problem. Activity levels range from basic to advanced and serve to enrich the curriculum with 21st Century Skills such as spreadsheet manipulations, calculations, graphs and programming among others. They do this while boosting students' understanding of the course content with a level of interaction with the material that would not be possible without the calculating power and immediate feedback that a spreadsheet can provide. Through their own preparation and student observation during classroom use of the activities, teachers will garner and reinforce their own skills with spreadsheets while creating a dynamic of students and teachers sharing their skills.
