Students investigate what happens when cubes of different sizes are constructed from unit cubes, the surface areas are painted, and the large cubes are taken apart. How many of the 1x1x1 unit cubes are painted on 3 faces, 2 faces, 1 face, no faces?
Finding Elevation (Limberg)
Finding the height of a hill has long been a task of surveyors. The method of leveling used in this activity is essentially what has been used for hundreds of years - the only major difference is that the level is supported by a tripod and the straw is replaced by a small telescope. (Modern methods use a portable laser in place of the telescope but the method is essentially the same.) This activity is well suited to a camp situation.
Measuring Distances - Triangulation (Michal)
Students learn to determine the distance to an object by sighting a distant object from 2 different locations and knowing the distance between them (parallax). Optional: use trigonometry to determine an unknown distance.
Water to the Max (Wood)
Students find the optimum angle of a hose to achieve the greatest distance a stream of water will travel. Activity involves measuring and recording distances

### Measuring the Earth

Eratosthenes Finds Diameter of Earth! (Donovan)
Students learn to estimate the diameter and circumference of the Earth by repeating Eratosthenes' experiment; exchange measured data and results; and use the Internet to research the mathematical and scientific contributions of Eratosthenes.
Measuring the Earth (Rich)
In this activity students will use their knowledge of geometry and trig. to determine the measure of an angle; use significant digits in their reports; calculate percent error; use their research skills to determine accepted values.
The Noon Observation Project - March 1996 or
The Noon Observation Project - March 1997 (Levin, Rogers, Waugh & Smith)

### Units of Measurement

Do You Measure Up? (Energy Conservation Enhancement - Louisiana)
Students solve problems concerning energy waste in the home by calculating needed amounts of weatherstripping, carpeting, insulation, and more.
No. 1: Adding Feet and Inches (NASA)
From a 9th grade math proficiency test. If Sally places a rocket 3' 6" tall atop a launchpad 1' 8" tall, how tall will the entire unit, rocket and launchpad, be when she is done?
No. 2: Measuring Boards (NASA)
From a 9th grade math proficiency test. Lewis needs 1,500 boards to build a small rocket. Each board must be 3' long.If boards are sold in 12' lengths, how many boards must Lewis buy and cut into 3' pieces to get the 1,500 boards he needs?
No. 9: Road Map - Scale (NASA)
From a 9th grade math proficiency test. If the scale on a road map is 1 inch = 250 miles, how many inches would represent 1250 miles?
No. 17: Measuring Things (NASA)
From a 9th grade math proficiency test. Which object is matched with its appropriate unit of measure?

### Sites where you can find more lessons and materials

Lessons by Susan Boone
Lessons developed by Susan Boone, a participant in GirlTECH '95, a program funded by CRPC Rice University and the RUSMP. A Functional Housing Market asks students to search the Internet for housing prices and compare them to the area of a house, thus deriving a linear equation. The Internet Pizza Server lets students order pizzas, calculating their area and determine the better buy. With Pop Clock, students look at the census site, study data and make predictions on future populations. Find the mean and median speeds for racers in the INDY 500. Study rates and speeds by using the Real-Time Traffic Report.

Metric System and Unit Conversion (Logan)
Advantages of the metric system: it was based on a decimal system (i.e.: powers of ten) and therefore simplifies calculations; it is used by most other nations of the world, and therefore has commercial and trade advantages.
