States of Matter Lab

We studied why thing of the same mass and density float or sink (Full pop cans). I think that the diet Coke floats because it was set in gently and didn’t break the surface tention but the Mt. Dew sank because it was just dropped in and had enough force to break the surface tention of the water then can’t float up.

 

Lesson 1: Matter, Matters

1.  What is Chemistry?

The study of matter and how it changes.

2. What is Matter?

Anything that has mass and volume

solubility – how well something dissolves in water

Lesson 2: Density

3.   States of Matter:

State

Energy

In a container…

What is the formula for Density?

Density = mass/volume

Density Lab Blog Post:

1. Explain what you did in the density lab and explain why the property of density determines whether an object will sink or float.  Also explain how can an two objects of the same size have different densities.

What are the building blocks of matter?

Atoms

Build a model of an atom including it’s parts and orbits.

 

Global Warming

in our science class we have been talking about global warming. here is a presentation about it. http://prezi.com/jmtjlfdijsga/a-challenge-to-the-city-of-zeeland/ (Copy paste the link to your search bar) so ways you can help are carpool or take the bus, don’t use as much heat for water or the air in your house, turn off water and lights when your done with them, don’t use an unexeptibale amount of anything that uses electricity, spread the word about it.
