For a science fair project we are comparing how plants grow in cold vs hot temps. I can keep the plants warm but how can I keep them cold without putting them in the refridgerator. I need a way so the get the same amount of sunlight as the warm plants

I suspect there are many serious errors in this book, but also much
that is important and true. She usually references sources which are, to say the least, not very authoritative. Your mission is to seperate the true from the false - give examples of errors.

This question is more for teachers or college profs. Through high school and college in just about all my labs: chem, physics, bio I remember blatently cheating experiments so that I could get some realistic info on my lab sheets. It got to the point to where I just got sick of doing labs because nothing ever worked out and I knew I would just fabricate data to make it look good. Do you think this happens often? And if so are our lab courses really teaching our generations of scientists to "fake it"? To this day I found all my undergrad labs were a waste of time.

"When solid sodium bicarbonate is heated in a test tube, an invisible gas, carbon dioxide is released into the surrounding air. Water condenses at the mouth of the test tube and a while solid residue, sodium carbonate, remains behind in the bottom of the test tube"
Is this one written as:
2NaHCO3--> Na2CO3 + CO2 + H2O?

What's the product of
Sodium hydroxide + Phenolphthalein + Hydrochloric acid?

Ethyl alcohol + water + [heat or the lighting of the alcohol with a butane safety lighter (would this be O2?)]??

:)

for electricity to flow, you need a voltage. so how does the neutral wire, which has no voltage, have an electricity flowing through it? thanks!

Log10 4 + log10 w = 2
The part I don't understand is the 2 at the end. How do I change that in order to solve the problem?

I'm having the same problem with this logarthim as well:
3 log5 (x^2+9) - 6 = 0
