This week was Science Fair week and the projects were great, I saw lots of focus on following the procedures and analyzing their data. One thing that could have had more time spent on was noticing and paying attention to the variables. Please take time to discuss this concept with your students at home. Here are a few of the projects that were entered.

Today we went over our review for our Science Milestone that we will be taking tomorrow. It will review all concepts from the Physical Science unit. Tomorrow, we will take our Milestone, and then on Thursday we will begin our Earth Science unit. We introduced 11 new vocabulary words that will be part of this week and next weeks' discussions.

Our words added are:

Sediments

Sedimentary Rocks

Weathering

Erosion

Deposition

Mechanical Weathering

Chemical Weathering

This week in Science we began talking about Forces and some of the different types of forces, such as gravity, magnetism, pushes, pulls, buoyancy etc. A force is a push or pull on an object, so gravity is the forces that PULLS objects to the Earth, Magnetism is a forces that PULLS magnetic objects together, etc. We discussed friction, and how it is the rubbing of two objects together that causes heat, we demonstrated this by furiously rubbing our hands together and feeling the warmth in our hands, we discussed how this is created on our tires when we drive, and one of the students made an astute connection with bowling, and the lanes being slicked to create LESS FRICTION!!! WOW, GREAT JOB GUYS!!!

We added these words to our vocabulary rings this week:

melting point 102

boiling point 103

freezing point 104

force 105

friction 106

air resistance 107

motion 108
