Name: Period: 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!
