Summary:

This week in class I learned about some of potassium’s physical and chemical properties. A physical property is something you can observe without it changing. A chemical property is something that says how it will react with something else and how it changes.  One of the physical properties of potassium is that it melts at 63.38 degrees Celsius.  One of the chemical properties of potassium is its reaction with water.  When potassium reacts with water it explodes and goes all over the place.

SP4 Analyzing and Interpreting Data:

I analyzed data this week by searching on Google, where I found some web sites and also checked the Google smart boxes.  I interpreted the data by reading it and putting the important information onto a Google slide that was called my element baby book.

Mixtures, molecules, and compounds 2/14

Summary: This week in class we learned about mixtures molecules and compounds. A mixture is two atoms that are not chemically bonded like a pile of rocks. A compound is two or more different atoms that are chemically bonded like water. A molecule is two or more of the same atoms that are chemically bonded like oxygen. FUN FACT three of the ways to separate mixtures are: chromatography, destoration, and filtration.


SP4 Analyzing and Interpreting  data:
In class how we analyzed data was we used a link or we watched a video, sometimes there was an interactive. We interpreted the data by put them on online worksheets that was made on wizer.me.

Chemical Changes 2/7/16

Summary:This week in class we learned about chemical changes. A chemical change happens if something is done to make a new form of matter, some examples are: ( I know this one might sound a little weird but it is true.) farting, evaporation, and when a star collapses on itself and becomes a black hole. There is another type of change in matter and it is called a physical change. physical changes happen when the matter looks different but is the same matter as before some examples are: moving my arm up and down, ripping a piece of paper, and digging a hole in the ground. Fun Fact: There are actually 5 states of for chemical changes to happen to!

SP3: Planning and carrying out investigations

We planned an investigation by setting up these two plates with holes in the and we put things like baking powder and baking soda. we carried out an investigation by mixing them with liquids like vinegar and water. In the end we got results.
