Guess the Legos

We are estimating populations in Science class. One good test is to see if you can guess how many objects are in a container. In my classroom there are Legos in a 1,000 mL beaker. How many do you think are in the beaker? Post your answer and you may be the lucky kid that wins the prize - getting to sit in Mr. Honer's desk chair for a class period!

Metric Measurement

Measuring is an important part of our lives. Most of the things that we buy are measured in some way or form. You may go to the hardware store and buy a certain length of rope, or go to the gas station and buy a certain volume of gas. In each case, something had to be measured. For most of the world, things are measured using the Metric System. The length of rope might be in meters and the gasoline would be in liters. The United States is one of the few countries that uses a different system (yards instead of meters and gallons instead of liters.) This leads to some tricky converting from one system to the other whenever different countries are working together. It often results in costly mistakes. For example, one gallon is not equal to one liter. Can you imagine the type of problems that can lead to?
Do you think that the United States should switch over to the metric system? Why or why not? Post your opinion today.
