Question: Could science get any more complicated?

Crossword help.

Fill in the blank for me please.

A(n) _________ experiment has two test groups-the control group and the experimental group.

second one:

Information, it’s a 4 word blank for that one.
No where it says information that’s not real information that’s the second blank and the only description is the word information. I need the blank for the first word. Sorry for the confusion.
And the only hint for the second word it’s a four word blank.

Answer: 1. A “controlled” experiment !!
(Do you have the number of letters as this seems too obvious and is therefore probably wrong?)
2. Data

Question: TEACH elementary school science?

in my chem class, we have to teach a classroom of 3rd graders something about chem or biology.

if you have any experiments or mini-labs i can teach them, that would be great!

i don’t want anything that every student has done. (i.e. making slime, invisible ink)

if you have any links, that would be helpful.

i’d also like it to be about 1.5-2 hours long, so i need it to be something interactive for the kids.

Answer: 1. 1.5 – 2 hours is an awfully long stretch.

2. If they have done it before, then adding a new twist will make the lesson interesting and more likely to be successful. Trying something new has endless potential for disaster. Unlike some adults, kids like repetition. That is the hardest thing for teachers like myself (who gets bored easily) had to learn.

3. I would try ooblek (cornstarch and water), which some kids will tell you is BOTH a solid and a liquid (but is actually a non-Newtonian fluid). That takes you right into before-and-after discussions of the definitions of solid and liquid.

Below is a video showing a metal expansion science experiment. There are many types of metal expansion Science Experiments, but the one shown in the video is a very easy experiment to measure how much metal expands when heated. You can do this Science Experiment At Home but be sure to have an adult supervise.

Metal Expansion Science Experiment

Thermal expansion has many uses. In this thermal metal expansion experiment, you need a wire of some sort such as an extended metal coat hanger, a candle, a light source and a needle.
