Conoce el maestro

My name is Pedro J. Miletti. I’m so thrilled to be the middle school’s Science teacher! It’s going to be a great year full of learning and meaningful experiences for all.I can't wait to get to know the new students and welcome back the others.

This year will be my 7th year teaching Science and the fourth one teaching in the US. The first three were in Puerto Rico. I completed a bachelor’s degree in Chemistry and a Master’s Degree in Math Teaching and Curriculum.I love to teach Science  because it gives the students the critical thinking skills they need in every subject. I believe in Learning by doing, teamwork and inquiry.

I hope you are as excited as I am to begin the school year. Nos vemos pronto!

Density and Buoyancy review

Density and Buoyancy Review


Vocabulary


Fluid - matter that can flow


Buoyancy - upward lifting force exerted by a fluid  


Mass - amount of matter


Volume - amount of space  


Weight - pulling force of gravity  


Density - relationship between mass and volume


Facts


Mass is always the same regardless of the gravity

Grams, milligrams and kilograms are SI units for mass


Weight on Earth is different than on the moon.

Oz and lb are units for weight


Buoyant force

Works against gravity

Some objects float in water because the objects weigh less than the weight of the water they displace.

The amount of water that is displaced when you submerge yourself in a swimming pool is equal to your body’s volume


Formulas


D= m/V m = VD V = m/D
