Fireworks: The Localized Big Bang
ORC# 10144
Resource Information
Resource URL:
http://www.ohiorc.org/pm/math/richproblemmath.aspx?pmrid=16
Resource Type:
Content Supports -- Activities and rich problems
Discipline:
Mathematics
Grades:
Grades 9–12
Professional Commentary:
Commercial fireworks must be carefully timed to ignite as intended. The process involves projectile motion that can be modeled with the quadratic function (ignoring air resistance), as found in the study of dynamics in physics: h = –16t2 + v0t + h0....

Only Graphs, Please!
ORC# 10145
Resource Information
Resource URL:
http://www.ohiorc.org/pm/math/richproblemmath.aspx?pmrid=66
Resource Type:
Content Supports -- Activities and rich problems
Discipline:
Mathematics
Grades:
Grades 8–12
Professional Commentary:
Students begin by graphing data points presented in unusual formats. They then construct the graph that fits those points. Using a creative technique, they are able to find the function rule that relates the data points even when the function is not a simple linear relationship....

Discipline:
Mathematics
Grades:
Grades 9–12
Professional Commentary:
In this problem, students develop a mathematical model that enables them to determine the fraction of the population that is using performing-enhancing substances based upon the parameters of the testing, parameters of the population, and the fraction of the tests that have positive results. From this, they can help determine whether or not authorities should test...
