I am almost finished reading over and making comments on your Science Fair Proposals.
Some students still need to hand these in and some only handed in a portion of the proposal.
If my comments ask you to complete a missing part of your proposal, please do so and turn it in before Friday 2/8/13
Most of the proposals are well written, some will be quite interesting and I'm excited to see your final results.
8th graders, you may want to start letting your family members know that you are looking for recycled materials for your inventions. I do have some paper towel tubes and other items available in the classroom that you may use when you are ready to build.
Things such as jar lids, Snapple or ice tea lids, old music CDs and lids from yogurt containers make great wheels that can be used for your pulleys.
Many of your designs did not show how you will support your machines, once you start building you will have to think about the support structures that are needed and why.
Remember, you don't want the ball to roll off of your machine, so you may want to think about how you will prevent this from happening.
