Infinity Mirror Infinity Mirror Hey, so, I've recently decided to build a infinity mirror, inspired by the idea on this website. I have one major question, what's the minimum/maximum distance between my pexiglass and mirror for it to work? Or is there any or does the distace affect certain things? Re: Infinity Mirror Hi - there isn't a set minimum/maximum distance for the mirror to work. The mirror's appearance depends on a lot of variables, light the brightness of the LEDs, the… Read more

Bioengineering a kidney project question Bioengineering a kidney project question I wanted to choose this science project because I thought I would be making a false kidney but it’s not about that at all :( I was very disappointed. Is there any project that I am able to chemically engineer something or is there any project on forensics that actually uses true criminal justice and crime evidence or something like that so that I can get a chance to actually experience my dream of being someone… Read more

Smelly Science: A Sniff Test

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

Smelly Science: A Sniff Test Smelly Science: A Sniff Test What is the unit of measurement for the dilution factor or odor threshold in the Smelly Test experiment? How would you write this in a graph of information? Re: Smelly Science: A Sniff Test Dilution factors are not measured in units, as they are ratios of the volume of the new sample (mL) as compared to the volume of the stock sample (mL). When dividing, units "cancel out," so the mL unit is no longer used. You can construct a bar… Read more

Hitting the Target: The Importance of Making Sure a Drug's Aim Is True Hitting the Target: The Importance of Making Sure a Drug's Aim Is True What does it mean when it says “Where do the "Patched" proteins match your sequence? Researchers do not know where the drugs bind the NPC1 protein, but where could the drugs bind and probably not also bind the Patched proteins?” ? In the BLAST website there is nothing labeled “patched”,and how am I supposed to know where the drugs bind? The graphical… Read more
