2018 Lesson #2 Chemistry, measuring & density

chemistry-740453_1920

This lesson we will be learning about PS1A- Structure and properties of matter, PS!B- Chemical reactions. I want to familiarize students with different ways of measuring things in a lab.

We will use the triple beam balance and weights, different scales and volumes and learn different ways of how to measure things.  

We will learn about density and what makes some liquids more dense than others and test out our theories.

Density is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density.”

Volume refers to the amount of space the object takes up. In other words, volume is a measure of the size of an object, just like height and width are ways to describe size. If the object is hollow (in other words, empty), volume is the amount of water it can hold.”

We will also build molecules with molecule kits

A molecule is the smallest unit of a substance that has all the properties of that substance. For instance, a water molecule is the smallest unit that is still water. A water molecule can be divided into tiny parts called atoms. This produces two hydrogen atoms and one oxygen atom.”
