Curated OER
Time Zones
Students solve time zone problems and chart travel around the world. In this time zone lesson, students learn about the history of time zones and view a time zone map. Students use the time zone map to solve time zone problems. ...
Curated OER
Time Around the World
Seventh graders investigate the characteristics of a time zone map. They read and interpret time zone maps. Students compare the time in various time zones. Students solve time zone problems.
Curated OER
Time Zones
Students are able to read and also use a variety of timetables and charts. They perform calculations with time, including 24-hour clock times and time zones. These are very important concepts that Students probably have to bear in mind...
Curated OER
Time Zones in the United States
Eighth graders explore how to use the time zones in the United States and internationally. They use elapsed time to solve problems. Students calculate the time in various places in the United States. They discuss the 6 time zones in the...

What Time Is It? (Latitude and Longitude)
Students practice latitude and longitude by identifying locations by degrees, use meanings of a.m. and p.m. appropriately, become familiar with 24-hour (universal) clock, and calculate time at different degrees longitude.
Curated OER
Understanding Latitude, Longitude, and Time Zones
Students take an imaginary world tour by locating cities with latitude and longitude. They plan an itinerary and calculate the time zones from which they would call home. Then they construct word problems involving travel across time zones.

Minnesota-China Connections:What Time Is It?
Students calculate the time difference between Beijing, China and their local community. They discuss how time difference affects intercultural communication.
Curated OER
Hang Time
Young scholars use the equation to calculate the vertical distance an object fall during 1 second in 1/10 second increments. (The acceleration due to gravity on the Earth=a= 9.8 m/s2) Using a graphing calculator, students plot the path...
Curated OER
Terminal Velocity
Students calculate acceleration due to gravity with the measurements of the period of a pendulum or measurements of the time for an object to fall from different heights. They observe and measure the effect of air resistance on the...
Curated OER
Tracking Speed
Students calculate the speed of an object, by measuring the amount of time it takes to cover a given distance, and then divide: speed=distance/time. However, the object may not have been moving at a constant rate over the given distance....
Space Awareness
The Climate in Numbers and Graphs
Weather versus climate: weather relates to short time periods while climate averages the weather of a period of many years. Scholars learn about average temperature and precipitation in various climate zones and then apply statistics...
Curated OER
Not Your Average Average
Students discover that if a distance is traveled in two or more segments at different average speeds, you cannot average the average speeds. Instead the total distance traveled must be divided by the total elapsed time. Students practice...
Curated OER
Big Air Rules
Students discuss projectile motion using a basketball player taking off for a slam dunk, a fly ball launched off a hitter's bat, and a snowboarder flying off a pipe as examples. The lesson is expanded by introducing the mathematical...
Curated OER
Hang Time
Students discuss how all objects fall at the same rate and vertical motion is independent of the horizontal motion. Students apply this information to center of mass activities before solving equations.
Curated OER
Tracking Speed
Students collect data for a runner by measuring the time it takes for the runner to run equal distances. After collecting data, students average speeds and accelerations for the runner. Assignment is completed by graphing the data.
Curated OER
In-Line Inertia
Students practice calculating the moment of inertia when discussing a skater and the position in which it is best to spin. After class discussion, students practice calculating inertia on their own.
Curated OER
Math Under Pressure
Students are told that an air tank contains a fixed volume of air under pressure. As air is used, the pressure decreases at a rate that depends on the depth. Students discuss how SCUBA divers calculate the amount of time they can spend...
Curated OER
Relaxing with Impulse
Students discuss Newton's second law of motion in terms of momentum and impulse using examples of landing on concrete versus dirt if you were to jump off an elevated platform or football players wearing protective padding. Mathematical...
Curated OER
The Math Reaction
Young scholars use the reaction time to figure out problems. They use the following example to get them started with reaction time: the edge of a ruler is placed near a person's thumb and index finger and, without warning, the ruler is...

Circles in the Landscape: Irrigating Oklahoma Crops
How do you grow crops in a area with insufficient rainfall? Why you irrigate, of course. Class members investigate irrigation systems by designing a system of their own. After examining irrigation related concepts, vocabulary terms, and...
