Building Your Own Tool for Identifying DNA Building Your Own Tool for Identifying DNA How would you be able to construct a hypothesis regarding the food colouring dye samples? Like how would you be able to make a scientific guess on which food colouring dye would migrate the furthest? I have researched and I know that different colours mean that the molecules the samples are made up of are different, but I don't know the scientific evidence to back it up, like if a certain colour would have… Read more

COVID/Vaccines / Computational Biology Project

COVID/Vaccines / Computational Biology Project COVID/Vaccines / Computational Biology Project I did a program that would compile data about COVID vaccines & the effects on the reality of high school students vs. what the media claims to be true. What I want to do this year is expand on different age groups and possibly create software that would represent what different cells for different age groups look like when they get infected with COVID-19. This project is a three-year project.… Read more

Help! Ovotransferrin impacts bacteria growth

Ask an Expert Topic Forum: Grades 9-12: Life, Earth, and Social Sciences

Help! Ovotransferrin impacts bacteria growth Help! Ovotransferrin impacts bacteria growth Hi, I wanted to test the antimicrobial effects of ovotransferrin on bacteria. Ovotransferrin works by binding to Fe3+ which most bacteria need. However, some bacteria need Fe2+ and some need Fe3+. I'm unsure where I should swab to get bacteria that will respond to the lack of Fe3+. Additionally, since I don't have the proper equipment to extract ovotransferrin from egg white, I plan on doing a rescue… Read more

Drug Solubility

Drug Solubility Drug Solubility How would I measure and test the solubility of drugs like pain-relievers? I researched a little on how to do it, but everything requires expensive lab equipment that neither I, or my school have. Is there some other way to test drug solubility that isn't as expensive? Also, how would I measure the solubility? Read more

Grade 9 Physics

Grade 9 Physics Grade 9 Physics We say that when a stationary train suddenly starts we tend to get a jerk back wards. As they say, it's due to inertia of rest (as the body needs to be brought in motion from rest) Now my question is, I don't get the fact that, how can we say that when the train is in motion, The body too is in motion. I mean, even after a jerk we continue to be in one place until we move by ourselves. I don't see any difference before and after the jerk as the body is still at… Read more

Gravity talk

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

Gravity talk Gravity talk Hey hope im not in a incorrect forum for this as im not a student just a curious mind. I hoped to have a real answer to my questions and this was the most working looking site for this. So to my questions. I was thinking about gravity, and had these thoughts. Is there anything behind them? 1. Is it correct in any kind to think einsteins theory(with my simple understanding) in a opposite view, as the space time trapping mass into these certain points of matter. 2. Is… Read more
