Brad Loewen, a competitor in the Science Olympiad event titled Metric Estimation, used the phrase "Challenge your students to a scavenger hunt with metric conversion problems!I hide 60 game cards with metric conversion problems in my room.To convert from meters to millimeters, it would take 3 jumps to the right which would mean the decimal would need to move 3 jumps to the right.

- For the mass lab, students first estimate the mass of various objects, then find the actual mass using triple-beam balances or other scales.

To prepare for the activity you will need to organize various items (coins, paper clips, marbles, rocks, large washers/s-hooks, etc.) and triple-beam balances or scales for each group.

They may group items together to reach a targeted mass, such as three pennies for 5 grams, or just use a single item.

This lab is always a hit and the students get much needed estimation practice. High, East Peoria, IL) involves using film canisters, a triple-beam balance, and a variety of materials to create a set of masses.

Since I have more than one science class each day, I allow the kids to "hide" the game cards for the next class.

- Print the "Metric Mania" (front of cards) on colored paper or cover stock, then print the problems on the back.If the students can get the canister to suspend with less than half of the lid above the surface, they should get numbers that result in a density close to 1.0 g/ml.Once the students have their canisters approved, they find the mass and volume of the canisters and calculate each density.Teams can only work on one card a time and must have the answer correct before they can start looking for another card.The team with the most cards at the end of the game wins a special reward - extra credit points or a piece of candy!My metric unit includes labs on length, mass, volume, density, and temperature as well as conversions (metric to metric and metric to English).Students have many opportunities to use rulers, triple-beam balances, and other science equipment to learn how to use the metric system of measurements.The "jumps" determine the number of times the decimal is moved and in which direction.I remind students to count the number of jumps it would take to move from one unit to another, such as moving from meters to millimeters, rather than counting the number of boxes.My students have difficulty relating the English system of measurement (feet, pounds, and gallons) to the metric units (meter, kilograms, and liters).The first lesson consists of making conversions from one system to the other.
