nynyny Posted February 3, 2012 Share Posted February 3, 2012 Where is the best place through the mail to purchase an inexpensive equilateral prism for the refraction lab as well as the various electrical supplies for the circuit lab? Up to now all the labs used household supplies. TIA Quote Link to comment Share on other sites More sharing options...
Sunshine State Sue Posted February 3, 2012 Share Posted February 3, 2012 I was able to purchase all the electrical supplies locally at Radio Shack. I brought the supply list with me, acted dumb, and they helped me. ;) Once I got home, I found each item online and linked them in an email to Derek. He then confirmed that I got the right thing or explained what I needed to get differently. Keep the receipt. I had to make 3 trips. The prism was the only thing I had to buy online. I'm not sure where I got it, but it might have been this one at Delta Education. HTH! Quote Link to comment Share on other sites More sharing options...
Handmaiden Posted February 3, 2012 Share Posted February 3, 2012 I bought the equilateral glass prism from our local teachers' supply store. I think it was cheaper than Amazon, but you can't beat Amazon's convenience, especially if you have Prime. Sue, thanks for sharing your tip about emailing Derek with links to electrical supplies. We're almost at that lab, and I can totally see myself buying the wrong parts! Quote Link to comment Share on other sites More sharing options...
Laura in CA Posted February 4, 2012 Share Posted February 4, 2012 Ooh, I'm glad I saw this thread -- y'all are a few weeks farther ahead than us (and here I thought my son was trucking through the material! :001_smile:). Thanks for the info -- it's just been stuff around the house until, I see, the last few labs. ~Laura Quote Link to comment Share on other sites More sharing options...
nynyny Posted February 4, 2012 Author Share Posted February 4, 2012 Thanks so much for your comments, Sue and everyone! I really appreciate your help!:) Quote Link to comment Share on other sites More sharing options...
Vida Winter Posted February 4, 2012 Share Posted February 4, 2012 Thanks for this thread. We haven't had to buy anything yet and I didn't know what was coming up. Quote Link to comment Share on other sites More sharing options...
MyThreeSons Posted February 4, 2012 Share Posted February 4, 2012 Hobby Lobby has a nice little science supply section. I don't know exactly what Mr. Owens requires, but I've seen prisms and basic electrical circuits components there, as well as other cool stuff. Lowe's also has some stuff in their specialty hardware section, although I haven't seen prisms there. Harbor Freight Tools has lots of cool stuff at cheap prices. They have a digital multimeter for about $6 that works great for measuring current, voltage and resistance in circuits. Radio Shack's DMM is nicer, but if you're only going to use it for a few Physics labs, I wouldn't spend the extra bucks. Quote Link to comment Share on other sites More sharing options...
Laura in CA Posted March 18, 2012 Share Posted March 18, 2012 I just got an email from Derek Owens (too late! we just got the prism and the electronics stuff at Radio Shack, haha), which everyone else taking physics right now must have gotten also, but I'm posting in case it helps folks later ... he's offering equipment kits for the last two labs to rent or buy. Here are the details. ~Laura ETA: perhaps this is in response to people pestering Derek about where to get the equipment? I hadn't wanted to bother him and we managed fine, but this would have been a nice alternative! Perhaps it's new ... Quote Link to comment Share on other sites More sharing options...
