optimal conditions for silicon oxidation

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

optimal conditions for silicon oxidation optimal conditions for silicon oxidation In the past, I investigated the optimal conditions for silicon oxidation and thought about how these conditions could affect semiconductor manufacturing. While doing this research, I became curious about how semiconductor companies in other countries deal with similar problems, and have you ever had a similar question? I found an interesting example in IBM's research on strained germanium. IBM developed a new… Read more

Need help coding with Python (edited) Need help coding with Python (edited) Hello, I am working on a science fair project on how long it takes for a computer program/code to decipher a password from one of the project ideas here. The first step is to download Python, however, when I do that, I can see the file, but not the other file to where I can actually build my code. How can I do this? -Emery (Edit: Turns out I cannot run Python on my school computer, so I am using W3Schools instead...… Read more

Alka-seltzer experiment w/ scientific design process

Alka-seltzer experiment w/ scientific design process Alka-seltzer experiment w/ scientific design process I am doing a school science project with Alka-seltzer at different temperatures of different liquids. I am using Coca-cola (cold), wine (cold), orange juice (cold), milk (cold), ice cold water (ice cold), and hot water (hot). I am trying to find out which will dissolve Alka-seltzer the fastest. I know it will be the hot water since the higher the temperature, the lower the dissolution… Read more

Need advice on an independent plant physiology project. Need advice on an independent plant physiology project. Hello Experts! I am an independent high school student (Grade 12 age 16) planning to conduct a controlled plant physiology experiment. I live in an area with no local laboratory for people my age or English fluent science teachers, so I ended up designing this home experiment that I think would be considered rigorous. I am investigating the interactions between thigmomorphogenesis… Read more

Growing Plants on Mars - Weather Implications

Growing Plants on Mars - Weather Implications Growing Plants on Mars - Weather Implications Hi, I am considering trying this experiment for my school's science fair which takes place in January of next year. This means I would most likely have to conduct the experiment during the winter. So I was thinking and now I'm concerned that the cold weather might affect the effectiveness of the experiment, and I do not have the space or materials to grow them inside my house. What would you… Read more

Question about Build a Balloon Car activity Question about Build a Balloon Car activity Type your question below and then press Submit! We are 9th graders, doing an experiment for physics, and we have to find the theory behind it. Could you give us like a summary on what's the theory and explain it to us? Also, is it the digging deeper part? If so, you just need to tell us if its in the digging deeper, because it said like the physics behind it, but does that mean the "physics" means the… Read more

Could I Use Local Weather Data for a Science Fair Project?

Could I Use Local Weather Data for a Science Fair Project? Could I Use Local Weather Data for a Science Fair Project? Could I Use Local Weather Data for a Science Fair Project? Hi everyone, I am considering a science fair project about how accurately local weather conditions can be predicted over a short period. I am particularly interested in comparing forecast information with the weather that actually occurs, rather than simply describing how weather works. My initial idea is to record… Read more

Struggling to Keep My Plant Growth Experiment Consistent

Struggling to Keep My Plant Growth Experiment Consistent Struggling to Keep My Plant Growth Experiment Consistent Hi everyone, I'm a college student taking an introductory biology lab, and my current project is looking at how different LED light colors affect basil seedling growth over four weeks. I thought this would be pretty straightforward, but I'm running into a problem. Even though I'm using the same pots, soil, watering schedule, and light duration, a few of the seedlings grew much… Read more
