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

Ask an Expert Topic Forum: Grades K-5: Life, Earth, and Social Sciences

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

Radios and Calculators Radios and Calculators I'm doing a soldering project to build an AM/FM radio and in my research the topic of making a metal detector using a radio and calculator came up. I understand the radio's purpose in the metal detector, but what properties of the calculator help make a metal detector work? Re: Radios and Calculators Hi - this forum is for K-12 students doing a science fair project. However, there are other forums online where you can get help with electronics… Read more

Determining Control for Experiment

Ask an Expert Topic Forum: Grades 6-8: Life, Earth, and Social Sciences

Determining Control for Experiment Determining Control for Experiment Hi! I was thinking about doing the Science Buddies project about whether or not young children can determine between if something is candy or medicine (4-6 year olds.) The science fair judges last year weighed scores heavily on making sure that students had a control in their experiment. In an experiment like this, how would you determine what the control is when it involves human behavior? Thank you! Re: Determining… Read more

Enzyme-Catalyzed Reaction

Ask an Expert Topic Forum: Grades 6-8: Life, Earth, and Social Sciences

Enzyme-Catalyzed Reaction Enzyme-Catalyzed Reaction Why does the enzyme catalyst bring the coffee filter square down? It goes up because the catalyst broke down the hydrogen peroxide into water and oxygen and the oxygen is less dense than hydrogen peroxide right? Re: Enzyme-Catalyzed Reaction Hi, Is this a question for a science project? The Ask an Expert forums are for questions about science projects or experiments.
