Wall adapter Wall adapter For How Loud Can Paper Speakers Get?, we were told to buy Jameco Part no.: 380156, 12 V, 2 A DC wall adapter, but it is not available. We cannot tell which of the Jameco “substitutes" is a viable alternative. Can anyone help? Thanks. Paul Re: Wall adapter Hi - did you also buy the mini audio amplifier from Amazon linked in the materials list? If so, any other 12V, 2A wall adapter should work as long as the barrel plug dimensions are the same - 2.1mm x 5.5mm.… Read more

Effect of Probiotics on Antibiotic Resistance

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

Effect of Probiotics on Antibiotic Resistance Effect of Probiotics on Antibiotic Resistance I had this idea for a science fair, I was thinking I could grow E. Coli in the presence of different probiotic foods on an agar plate, and then expose those to another agar plate with antibiotics to test the effects. My question is about the experimental design for this experiment. I was planning on putting the probiotic foods into the LB agar broth itself, and then plating the E. Coli on top of that.… Read more

What reflects IR light but not UVA/UVB?

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

What reflects IR light but not UVA/UVB? What reflects IR light but not UVA/UVB? Trying to find a material that is highly reflective of most/all IR/NIR light, whilst being minimally reflective, or ideally not reflective at all of UVA/UVB light. So far it seems like gold is a top contender. Two questions. 1) Is gold/gold-plated metal the best option? 2) Is it gold's composition or its color that exhibits these properties? Given the cost, could a gold-colored metal, or even gold aluminum foil,… Read more
