Dollar on Fire• Fuel + Oxygen yields heat• Why did the dollar not burn? • What does density have to do with
this?
TO DOAbout Me Letter to Mr. Narez
Engineering a Vehicle • You have 40 minutes to construct a
vehicle that can travel 6 feet without touching it.
• You only get 10 seconds once your trial begins
• You can only use the materials given to you
• You don’t have to use all the materials• Engineering – making something both
efficiently and cost-effective.

Why Study Chem? It’s everywhere!
Chemicals are everywhere from fluoride to peroxides to baking soda in toothpaste
To detergents and soaps that break oils and grease To fuels found in lighters and mousse Ozone found in the atmosphere To vitamins and minerals (iron) you consume To the lead in gasoline that helps form a combustion
reaction To pressure caused by molecules moving at high speeds To acids that cause heartburn to bases that relieve
heart burn

2 Density Lab Notes: Density by Displacement

Top Jobs in America
7 Layer Demo – Youtube or Demo
Why did the mixtures separate?
Density of a regular shaped object
Density is the mass per unit of volume
Density = Mass
Volume
Very large mass in a very small space, then we say that it is very dense.
Very small mass in a very large space, then we say that it is not very dense.
Manipulating Variables
Example: Find the density of this cube if the mass is 45 grams.
Density = m/ v
D = m / (l x w x h)
D = 45 grams / 90 m3
D = 0.5 g/m3
Draw box with measurements
Is this very dense or not very dense?
Is this very dense or not very dense?
.
Calculating Volume by Displacement
Many objects have odd shapes and don’t have an easy way to calculate its volume.
Volume by displacement is an easy way to calculate volume.
1. Measure initial volume (4.8mL)
2. put object you want to measure inside. Find the final volume (5.6mL)
3. Volume of dinosaur is difference:
5.6-4.8 = 0.8mL
Formulating a Hypothesis
A hypothesis is an educated guess or a proposed explanation to why you think something is happening.
Usually given as an “If _______, then ______” statement.
Example: If I put salt in water, then it will dissolve.
NOTE – A hypothesis must be testable
Write a Hypothesis for this Lab
To Do: Find the density of the group of pennies, match with given values, that’s what is inside the copper pennies.
