Science Extra Credit
There are 3 options for extra credit that you can
do over winter break! For each project I need to see a video, or
pictures of you doing the project for you to get credit!
DUE: 1/7/15
Option A: Density
Just like putting the soda cans in the container, your job is to test the
density of 5 different materials in your house. Take pictures or a video
of you dropping the objects in water and seeing if they float or sink! DO
NOT drop in materials that will get damaged by the water!
Option B: Mixtures
Make a mixture of 3 materials from objects around your house. You can
try salt, sugar, kool-aid, ice, water, whatever! After making the mixture
try to separate the mixture using the physical properties we discussed
in class. (Think sifters, water, freezing, boiling) DO NOT make a mess or
use things that you are not allowed!
Option C: Density Simulation
If the two other options are too messy for you, here is an online
simulation! Go to https://phet.colorado.edu/en/simulation/density
There are different blocks of materials, try to get each one to float and
sink by adjusting the mass and volume! Take a picture of each block
floating or sinking!
