Explanation for Rusting of Iron Nail Project!

Ask an Expert Topic Forum: Grades 9-12: Physical Science

Explanation for Rusting of Iron Nail Project! Explanation for Rusting of Iron Nail Project! Hello! I am currently working on a project about rusting of iron nails and how the corrosion changes depending on the metal used to 'protect' (wrap) the iron nails with. The reactions in this experiment rely on normal iron being Iron(III) and rusted iron leeching a form of Iron(II). The experiment is fairly qualitative, and involves use of the reaction between potassium ferricyanide and Iron(II)… Read more

Idea on how to "cure" cancer Idea on how to "cure" cancer Hello, I was wondering if I could get some help on a few things. First my idea that I have is that if I could create a DNA sequence that would create a poison inside the cell only if the cells Cyclin B levels got to above what they should be at. I first need help trying to figure out the process you would use in order figure out cyclin levels in a normal cell and then in a cancerous cell. Next I would need help… Read more

Tornado Damage Science Fair Project

Tornado Damage Science Fair Project Tornado Damage Science Fair Project My student created her own experiment to test if building height factors into whether or not it will remain standing in a tornado. She built three buildings of varying heights (short, medium height and tall) and used a box fan as wind and observed and recorded damage. Each building was made with the same blocks and the fan was the same distance from each building during each trial. Also, the fan was on high for the same… Read more

Affect of Fertilizer on Photosynthesis Affect of Fertilizer on Photosynthesis Hi I'm working on my Science Fair project and I am wondering about doing the floating leaf assay experiment. I would like to try and make it an experiment though that relates to water quality. Would something like adding something sulphur or nitrogen based to the water that the disks are floating in make a difference to the rate of photosynthesis or would this have little impact? There is a lot of talk around at the… Read more
