In this activity, students will simulate a pipe leaking and collect data. Students will then use the TI-73 calculator to determine how many gallons would leak at that rate for a 30-day month.

Rainforests at the Crossroads: Use a TI-73 Explorer to become familiar with a graphical technique for measuring the amount of leaves Leaf Cutter Ants chew. Measure the mass of a chewed leaf and then find its area.

When two or more chemicals react, other substances such as gases may be produced. The rate at which the reaction takes place can be affected by a number of different factors including temperature. In this activity, you will see how...

In this activity, students will investigate the given function, and state and explain the limit at a particular value. They also state and explain the limit at a particular value from a graph.

Students will learn to write the half reactions that occur at each electrode during the electrolysis of water, performed in microscale using a 9V battery as a power source. In monitoring the pH at each electrode, studens will learn that...

A classic problem looking at maximizing the area of rectangles given fixed perimeters. Uses graphing calculators to analyze data collected and to model a parabolic equation. Compiling class data provides a preliminary glance at families...

Rainforest at the Crossroads: Simulate the motion of an animal using a rectangular object placed at different positions on the floor. Then measure and graph the animal's coordinates, and examine its path.

Disappearing Wetlands: Examine changes in sediment deposition at locations along the Mississippi River using data collected at two stations by the U.S. Geological Survey (USGS).

Disappearing Wetlands: Simulate sediment reintroduction channels using a ramp at two slopes. They will then find the kinetic energy of the ball at different times as it rolls down the ramp.

Freezing temperature, the temperature at which a substance turns from liquid to solid, and melting temperature, the temperature at which a substance turns from a solid to a liquid, are characteristic physical properties. In this...

In this activity, you will look at the relationship between the age at which you start drawing social security and the amount drawn. Both graphs and spreadsheets will be used.

Rainforests at the Crossroads: Use a set of XY coordinates to map the locations of an agouti and an ocelot at one-hour intervals. After determining the locations of the animals, use the information to solve the mystery behind the...

In this study of conics, students will examine the derivation of equations for circles. There are two general equations for circles. The first is a circle whose center is at the origin, while the second is a circle whose center is not at...

In this activity students will look at the potential impact of an improvement in the equipment used by world-class swimmers. They will also look at the improvement in the world records for men and women in the 100 Meter Freestyle race.

A classic problem looking at maximizing volume by varying the height of a box. Uses graphing calculators to analyze data collected and to model a cubic equation. Look for points that maximize volume while developing a preliminary notion...

In this activity, students' will explore how the tilt of the earth's axis results in different amounts of solar radiation at different times of the year, causing seasons. They will simulate the earth's warming using a light bulb that...

Students will measure the lengths of the sides of three different triangles and apply Heron's Formula to calculate the area in acres. The measurements for this activity may be done outside or, using a specified scale, completed inside....

Based off of the hit television show NUMB3RS, this lesson exposes students to graphs using logarithmic scales. Although the graphs are at first non-intuitive, students should quickly "get used" to the scale. The lesson leads to a good...

This activity is intended for an Introductory Meteorology class; an earth science elective intended for Juniors and Seniors. (It was orginally modifed from an Introductory Meteorology Laboratory Assigment taught to undergraduates at...

In this activity, you will construct special segments of a triangle named altitudes, medians, and angle bisectors, Using their definitions. You will look at how an altitude, a median, and an angle bisector divide the area of a triangle....

In this activity, students' will use a motion detector to determine what effect the speed at which a person moves has on the appearance of the distance versus time plot.

Based off of the hit television show NUMB3RS, this lesson shows students a real-world application to matrices and matrix operations. Framed in the context of a stolen painting which the thief may hide at different warehouses, students...

Based off of the hit television show NUMB3RS, this lesson shows students a real-world application to matrices and matrix operations. Framed in the context of a stolen painting which the thief may hide at different warehouses, students...

Based off of the hit television show NUMB3RS, this lesson has students take a greater look at tree diagrams, especially in relation to decision making. Game theory figures in on this lesson, as students try to determine which choices...
