Throwing away all the political and financial pressure that dilutes and warps science, if one wants to engage in scientific inquiry and be productive and contribute in some small way to humanity's scientific understanding of the cosmos, how does one go about things? Can we boil things down to simple generalized steps -- brief enough to put on a wall plaque -- starting with the evaluation of an experimental idea (is it a "good" experiment?) all the way through to publishing one's reproducible results?

We can't figure out a good title for my daughter's Science Fair Project. The school wants the 4th grade children to basically do the whole project at home with guidance from the parents.
My daughter's experiment is on why apples turn brown and she is learning about why the lemon juice worked (learning about acids and bases, etc.)
The poster board we will use will have a title on it. The teacher wants us to think of a good title, and it does not necessarily have to be the question, "Why do apples turn brown". It can be a clever, or interesting title that goes with the experiment. At first we thought about, "An apple a day keeps the doctor away." But then we thought it was too long, and it also might be presumed that her project is about apples and how they are healthy. [more inside]

My daughter is in first grade, and her class is studying solids, liquids, and gases. I want to come in and do some related fun science demo to engage and amuse them. Bonus points if I can somehow tie it into a short children's book, so I can read the book first and then conduct a themed experiment based on the story. They have likely seen some of the basic common science demonstrations, but I am open to anything if it works with a story. It also needs to be educational, safe and relatively inexpensive (Under $50 or so, so dry ice is fine, gallium spoons not so much). I work at a research university, but on the social science side, but can probably hit up medical researchers for equipment, if it would help. Any ideas are appreciated, especially with suggestions for books as well!

I remember a site where you load it up and it says something simple, like "I like tea". And then you click tea and it expands so it says "I like really good tea." And then you can click other words, over and over, until there's finally a whole paragraph.
Love the site. Can't remember where it is. Can anyone remember?

I have a project where I need to see inside a sealed cup to see water flow pattern. The water is hot. I was thinking of a fiber optic camera, but need some help. The idea would be to make this repeatable. So the top and bottom are punctured to push water through at brew time.
Any thoughts on device? Setup?

I was recently in an Emotional Intelligence course where the facilitator discussed the "Three Chair Experiment," where three people sat beside each other without saying a word for 10 minutes. The result was the experiment was that all three people would eventually take on the emotions of the "emotionally strongest" individual - ie if someone was really happy, the other two would end up being happy too, even without talking. Or if someone was really angry, the other two would end up also being angry after the 10 minutes. I thought it was really interesting so I googled it, but couldn't find any more information. Has anyone else heard about this experiment? Are there any sites or papers out there that provide more information about this?

I'm trying to find information about taxes and volunteer paid experimental (non-clinical) studies. I work in a lab, and one of our participants told us a week ago that if a study pays (the volunteer) over a certain amount, it gets taxed. Can anyone tell me if this is true and give me an official link? We're in Philadelphia, PA, USA. I can provide any other relevant information you need. Thanks!

[StatisticsFilter] I’m trying to understand the extent that the statics of a particular experiment can be evaluated and trying to relate that to a 95% confidence interval. The experiment is considered “a standard”, but I want to keep the discussion as “high level” as I can so that we focus on only the relevant details. Any help or pointers in the right direction are greatly appreciated. [more inside]

My dog Duffy is very smart and even though he's pretty old he learns new things fast, so I am doing an experiment with him and I am finding his failure to pick up the trigger puzzling. He discerns the most subtle cues from others when he's trying to decide what to do next, so I wonder how this isn't working. [more inside]

Several years ago a psychology experiment found that in emergency situations, the body seems to engage in fight/flight before the cortex determines that, say, a lion is running at us. Can anyone help me find that study? And, for extra points, any subsequent studies showing action coming before thought in other sorts of scenarios?

When I was in college, probably in 1995 or 96, I was shown two short videos as part of an experiment that a graduate student in linguistics was conducting and then asked to describe the events in each.
I was later told that the first video was from a well-known psychology experiment and was shown to subjects as a control. The experiment was about my reaction to the second video.
Ever since then I've been wondering about that first video. [more inside]

I remember doing a discussion activity/thought experiment in high school where we had to choose 6-8 people from a list (e.g. pregnant teen, scientist, priest, stay-at-home mom, doctor) to save in a nuclear apocalypse and justify our decision. There was a paper handout associated with the activity, and I'm pretty sure my teacher didn't write it himself, because I've talked to friends who've done the same thing in a different context (church groups, retreats, etc. ).
I'm looking for a link to a copy of this activity, or a place where I'd be able to find it.

Computer Coding: I'm trying to write an experiment in E-Prime
that uses a Visual Analog Scale to allow subjects to bid on items. Basically, this means they move a slider with their mouse over a bar, and the position on the bar represents how much they are willing to bid. The thing is, they need to know what value
the slider currently represents before they can actually bid, and I'm having problems getting the text to update with the cursor position. Now, if any of you out there are E-Prime gurus I could really use your help for this bit. I need to figure out how to update a textbox in a 'slide' object in the middle of a loop. [more inside]

Okay, here is my dilemma. I'm trying to get an experiment running in which I present a series of BMPs to my participants. After months of pain and suffering, I have finally tweaked a set of stimuli which work for me, so I'm swimming in around 3500 BMPs.
But, since I can only torture my participants for an hour, I can only ask them to go through about 1200 of these BMPs, so I need some way to quickly and easily generate a selection of random BMPs from my bigger collection. [more inside]

Any suggestions? [more inside]
