Rice husk ash-derived zeolites as a marine habitat Rice husk ash-derived zeolites as a marine habitat Hello, I am a junior interested in conducting an experiment involving the synthesis of zeolites from rice husk ash. So far my research has indicated that I need to use a hydrothermal reaction to produce these zeolites, but I do not have access to an autoclave or a controlled heat source. My goal is to create a habitat for marine life that also adsorbs nitrate from water. This will require me… Read more

Unusual photosynthesis lab results

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

Unusual photosynthesis lab results Unusual photosynthesis lab results In executing a lab where the rate of photosynthesis was to be measured as per the impact of controllable variables, my group obtained inconclusive results that we can't seem to definitively justify. In theory, variables aside, the results produced by measuring O2 levels over time should have indicated an upward trend - however in our control group, where we were simply observing the rate at which photosynthesis naturally… Read more

Nanosized Holograms Nanosized Holograms I entered a science based competition to help get kids pumped about science and back into the swing of normalcy in the upcoming school year and wanted to go all out since I have the time on my hands and the project isn't due for about another 5-6 months. I was wondering if it was possible to make a mask made of holographic cells that are Nano sized or if it is possible to make a mask out of nanotech? I have a few months on my hands before the project is… Read more
