How Dense Are You?

Density is a concept that we will use this unit. It is a relationship between mass and volume of an object, where mass will be divided by the volume of the object. The density of water for example has a density of 1.0 g/ml. The density of aluminum is 2.7 g/ml. Anything that is said to have a density greater than 1.0g/ml will sink in water and those with a density less than 1.0g/ml will float in water.

Why then will a gigantic ship made mainly of steel (let's call that a density of 7.8 g/ml) float in water fairly easily with many passengers and potentially a massive cargo aboard? Discuss your answer in a logical, well organized fashion (1 paragraph or more if you are up to it). You may even have to do some research. Do not ask your parents! Type up your response, post it here by Friday, Sept. 17th. Good luck and have a great weekend!

Putting Your Best Foot Forward

The first week of school is over and we are well into the swing of things. Students are becoming more engaged in learning as the weary eyes of summer fade. I am enthusiastic about what I have seen and heard thus far from my students. Detailed responses to in class questions and a genuine effort to succeed is being displayed. That is all I can generally ask of my students. Always try your best in whatever you do. If you work only half as hard, you get only half the results. No matter what the difficulties that arise happen to be, attempt to be a leader in your own educational experience. If you always put your best foot forward, you will reap the benefits later in life. Sometimes taking a big step forward comes after some smaller steps backwards. That is all part of the journey in education and the beauty of it. Sometimes the best learning experiences come from our failures and that makes all the difference.
