This was used to lower the freezing point of the ice in making Ice Cream.
What is Salt.

There are 3 major ways an oil spill can injure wildlife. Name one.
The oil gets on the fur and feathers and destroys the insulation value. Birds and mammals then die of hypothermia (they get too cold).
Animals eat the oil, either while trying to clean the oil off their fur and feathers or while scavenging on dead animals. The oil is a poison that causes death.
The oil impacts animals in ways that do not lead to a quick death, such as damaging the liver or causing blindness. An impaired animal cannot compete for food and avoid predators. Oil also affects animals in nonlethal ways such as impairing reproduction.
You can substitute sugar for salt to lower the freezing point of the ice. True or False
False.
In let's make ice cream you learned about a type of engineer. What was that engineer called?
What is Chemical Engineering.
What is considered the earliest adhesive?
Bitumen
How much were the pair of tweezers to clean up the oil spill?
1,000,000
If you made strawberry or chocolate ice cream, what did you have to do with the amount of sugar?
Use half the amount.
1/8 cup vs. 1/4 a cup
The April 20, 2010 explosion of an offshore oil rig in the ___________________ caused a catastrophic oil spill that has affected local economies, wildlife, and the coastal ecosystem.
Gulf of Mexico
Explain the difference between adhesion and cohesion
Adhesion – glue sticking to the substrate material
Cohesion – glue sticking to itself
Three things need to happen in order to have an oil spill considered "cleaned up"
First the oil must be contained. The oil then needs to be removed or dissolved and the environment needs to be restored so that it is once again safe for wildlife.
What was the "popsicle" orgingally called?
The Epsicle.
The initial temperature of the ice was 32*F. What temperature did it drop to when you added the salt?
0*F
