Grade 8 Science February 17, 2011

Hi there... you need to blog the answer to the following questions...and then post a link to an interesting optical illusion as an intro to our next unit!

1. What is the density of an object with a mass of 15g and a volume of 5cm^3?
2. List and order 4 household liquids from highest to lowest viscosity.
3. What happens to the volume of a balloon when you take it outside into a -35 degree celsius environment?
4. Complete the following: As the temperature increases on a fluid the pressure _______________.
5. Find out which of the following metals has the highest density: Copper, Aluminum, or magnesium.
 6. Have a great day!


There will be an award someone with all correct responses!

    question1- 3cm^3

    Question2- high v= honey,syrup, oil and water.

    Question3- It deflates

    Queston4- The pressure goes up.

    Question5- magnesium

    1. The density of an object with a mass of 15g and a volume of 5cm^3 = 75g/cm^3
    2. From highest Viscosity = Oil, Orange juice with pulp, Apple juice, water !
    3. The balloon with inflate .
    4. The pressure changes also,
    5. copper

    1. 3cm^3
    2. honey,maple syrup ,oil,water

    has many optical illusions including a common one of a duck/bunny!

    1. What is the density of an object with a mass of 15g and a volume of 5cm^3? the density would be 3g/cm^3
    2. List and order 4 household liquids from highest to lowest viscosity.
    honey
    milk
    water
    vinegar
    3. What happens to the volume of a balloon when you take it outside into a -35 degree celsius environment? The volume decreases!
    4. Complete the following: As the temperature increases on a fluid the pressure _Increases also_.
    5. Find out which of the following metals has the highest density? Copper has the highest density.
    6. Have a great day.. I did that to so the list is complete

    Have a good day!
