Best science classroom measurement kits according to redditors

Yes, you are correct that it still illegal to ship live ant queens through the mail, or at least it's a grey area.

I actually had the exact same problem when I started in the hobby. I learned that I would have to capture my own queen and quickly gave up on the idea. The next year I was swimming early in the morning and saw a bug land in the water, then another, then another. I then found the forum formiculture.com and asked for help with identification. Sure enough they were all queens that had just mated mid flight and flown down to find a suitable spot for a founding chamber.

Since then I have found more queens than I can handle and I realized it's way easier than I had previously thought. Most of the time I'm not even looking.

If you are anywhere in the northern hemisphere, right now is most likely a perfect time to find queens.

Ants Canada has a ton of videos that can help you get started like this one. As you can see, he just walks around his neighborhood in the summer and finds them fairly easily.

I recommend using plastic pill bottles to collect them.

With all that being said, you absolutely can buy queens, you just can't ship them. Check out http://www.antscanada.com/queen-ants-for-sale/ Also ant forums (I prefer formiculture.com) usually have plenty of people selling queens locally all the time, or even selling/donating full colonies.

If you (or anyone else) has any more questions about the hobby, feel free to ask.

FYI you can buy this stuff in little sheets that's a lot nicer to work with like this

Clever to print directly into it, I'm gonna have to give that a try

Buying uranium ore on Amazon: $39.95

Seeing top result from Amazon is a testicle self exam form: priceless

(I kid, but, guys, you really should be checking for testicular cancer especially if you keep your uranium ore in your pocket.)

Not comprehensive, but some of the bare-bones basics to me are:

• 1000mL beakers
  
• 200mL beakers
  
• 100mL graduated cylinders (glass!)
  
• eyedroppers (glass)
  
• big box of transfer pipettes (can be plastic)
  
• hot plates (in Celsius or Kelvin)
  
• glass thermometers
  
• glass stirring rods
  
• Ring stands
  
• alcohol lamps (you want open flame for some stuff like flame tests)
  
• plastic sample containers
  
• Burettes
  
  For chemical supplies, I would get the highest concentration you can safely store (depends if you have a hazardous chemical safe or not) but it's easy to take a strong concentration and dilute it, but if all you have is like 4% NaOH and you need 40% you're boned.
  
  
• Ethanol
  
• Sodium hydroxide
  
• Sodium carbonate
  
• hydrogen peroxide
  
• hydrogen fluoride
  
• Bromine
  
• Calcium Carbonate
  
• Iodine
  
• Nitric Acid
  
• Sulfuric Acid
  
• hydrochloric acid
  
• Phosphorous
  
• Phosphoric Acid
  
• Sulfur
  
• Glycerin
  
• Borax
  
• isopropyl alcohol
  
• universal indicator
  
  Most of that is pretty safe to store except some of the acids and the peroxide depending on the concentration.
  
  If it's in your budget, also you should really have a flammables cabinet, and a fume hood.
  
  Ohh, also I love the moly-mod kits. Those are great if you can get your admin to get them. Not technically lab equipment, but great for hands on exploring of molecules. If you're doing any organic chemistry I think they're really a necessity and by school standards they're really cheap.

This has been known in the scientific community for years. I am not sure why it has not gotten more attention. Even with all the ALS ice bucket challenge posts a couple years ago you think this would have been picked up by the media. I live on a lake and participate as a tester for the lake authority using a secchi disk. It helps determine how much cyanobacteria is in the lake and whether it is safe to swim. I mainly due this because I have/had a couple of close friends with ALS and I suspect it is from the lake.

Here is the link to what I got-

I found something for you: Testicle Exam Form

Hopefully these will let you find your balls. If you're dating someone and your arguments always go like that, you're doing it wrong.

Density blocks work pretty well if you already have some of those.

Much better reviews https://www.amazon.com/dp/B007G0MW2Q/ref=cm_sw_em_r_mt_dp_U_uD7CDb7S7RN7M

Depends on if its amazon or a 3rd party seller. You can always pay extra to get it faster shipping but that may be double or triple the cost of the model set.

Edit: Model Kit from Picture

Looks like March 5th - 8th if you do free shipping, but possible march 1st at fastest

I was going to say "testicle exam" until I found this. WTF?!

I always like testing nutritional claims of foodstuffs.

Here is a link to a newspaper article discussing the two 14 year old girls who discovered Glaxo-Smith Kleine was lying about the vitamin C in cranberry juice. It resulted in GSK getting a ~USD 2 million fine.

You can get a 50-pack of vitamin C test strips for ~$20.

Test a few brands of the same product, a few different products, discuss your results. Check out the superfood section of some stores and see which companies are making fraudulent claims.

Report on why is vitamin C important, how much should we eat per day, which are the best/worst sources?

In den USA ist es allerdings kein Problem solche Würfel in genau der Größe billig zu bekommen. https://www.amazon.com/United-Scientific-DCSET10-Density-Cubes/dp/B00ET6H38S

Well, this is pretty cool.

Op Google "Kubus dichtheid set" kom ik een aantal dingen tegen:

Of op Amazon Duitsland:

What about Amazon?

I'm more concerned by this, found under "Customers Who Viewed This Item Also Viewed"

We borrowed mass cubes from the science department, which happen to fit perfectly inside tetrix channels. Tapped the cubes in there, and then tape the weighted channel inside the robot's actobotics channel. Somthing like this:

https://www.amazon.com/United-Scientific-DCSET10-Density-Cubes/dp/B00ET6H38S

To balance it? We center the robot on the balance stone. Then pull the robot close to an edge with the wheels near the other edge. If one end of the board touches the ground and the other doesn't, you know which side is heavier. It's not perfect, but cheap!

I searched "uranium ore" on Amazon and this came up.

I think what you're looking for is a "plastic vial"?
Maybe something like this

I searched for uranium ore and I was given a "testecle self exam" Pratice sack

shipping weight is 8 pounds. odd.

I just starterd Org. Chem 1 and this $21 model kit has been super helpful to me. It can do single, double, and triple bonds well, the colors are super vibrant, and it all fits well in the little box it comes in. I don't know about cyclohexane, but I make benzyne rings all the time and this helps me understand degrees of saturation and unique carbons and hydrogens, too.

https://www.amazon.com/Organic-Chemistry-Model-Pieces-Instructional/dp/B01NCU854K/ref=sr_1_4?keywords=atom+model+kit&qid=1569186732&sr=8-4

This is pretty close to the one I had. I got one at my school's bookstore, but that one look pretty similar. They help a lot with the cyclohexane rings and chair structures, for me. Also, if the school you go to has a workshop section that goes with the class, that might help. My school had a section with a TA and several other students who would go through the practice problems together.

The best part is that they are sold out of these:

This is what I saw on Amazon when I clicked a top-of-reddit-page ad that said something like "I was looking for Uranium, how did Amazon know I wanted this?"

You mean like these http://www.amazon.com/3B-Scientific-W43014-Testicle-Self/dp/B005OSVZN4/ref=pd_sim_sbs_ol_4 or this
