    Best answer: Continuing on from billrussel's answer

    On his item 2) - His comment is correct, but you are also correct that batteries from different manufacturers may have different lifetime characteristics, so you should keep the battery manufacturer as a controlled variable.

    On his item 4) - This was my initial reaction to your post. Storage temperature is not going to affect any results that you can produce in a reasonable amount of time for this sort of project. However, the temperature at which the batteries are used may have a large difference. For example, my camera batteries last only a short time at frigid temperatures, but last much longer in the summer. I suggest that you make your experimental variable usage temperature, not storage temperature. Be sure to soak your batteries at the usage temperature for a few hours before testing them to be sure that they have fully reached the desired temperature.

    Another problem is that you have no idea how long, nor under what conditions, the batteries were stored prior to your purchase. You should probably discuss storage temperature in your conclusions and recommendations section, noting that the initial condition of the batteries was outside the scope of the study and may have some effect on the results.

    One other note. How are you going to determine when a battery is exhausted? A torch/flashlight is fine as a load because it is a simple resistive load, but at what point do you say the battery is gone? I suggest that you modify your torch so that you can attach a voltmeter across the bulb. If you have two 1.5 V cells in your torch, you might want to set a threshold of, say, 2.0 volts as a point where the battery is considered depleted. Using a voltmeter will also allow you to plot battery voltage vs time, which should make for some nice comparison graphs in your report.

    This is a pretty decent science project. I wish you well

  • Is science proof? Is there such thing as scientific proof?

    Best answer: No! Proof tends to sound absolute. If a scientist were to say I have proven that everything is composed of atoms he/she is making a claim that it is proven beyond all doubt. Science does not do proofs. Mathematics, which is dealing with abstract concepts anyway, does do proofs. Proofs can also be done in Logic. In... show more
    Best answer: No! Proof tends to sound absolute. If a scientist were to say I have proven that everything is composed of atoms he/she is making a claim that it is proven beyond all doubt. Science does not do proofs. Mathematics, which is dealing with abstract concepts anyway, does do proofs. Proofs can also be done in Logic.

    In science we deal with what we call evidence. Scientists follow the preponderance of the evidence. In other words they go where the evidence takes them even if it is in an unexpected direction. Scientists must remain sceptical. This means that they have to be prepared to accept that one day better evidence will be found and that it will be contrary to previous evidence. Therefore, in science we only accept something for as long as the evidence supports it.

    There are some things in science that have a lot of evidence and all the evidence continues to support a particular set of facts. Some of these have been known and supported by evidence for so long that scientists generally believe it is unlikely evidence contrary to what is known will be found. So, scientists generally say these things are proven. But it is like talking slang rather than properly. To say it is proven is convenient although this can never be the official position. Some things that science considers to be "proven" are atomic theory of matter, evolution, germ theory of disease, gravity, heliocentric model of the solar system, etc.

  • Where is the global warming sea level rise?

    Best answer: The 'science' of global climate change is far from precise. The various models don't agree with each other, and none of them accurately predict previous climate retroactively.

    Best answer: The 'science' of global climate change is far from precise. The various models don't agree with each other, and none of them accurately predict previous climate retroactively. Confidence in predictions into the future are poor. Funding is unbalance toward those who propose studies to prove AGW, a strong political bias. Data is cherry picked to provide the desired outcomes and contradicting data is hidden/disregarded.

    It's an area of study that certainly deserves additional examinations, but the 'science' is *far* from settled.

    I was having a conversation with my kid who is 13 recently and found out they don’t believe in many different scientific facts because it’s not in bible or would contradict the Bible. I was tempted to go a rant about how the Bible is most likely just a bunch of fairytale stories. But I choose to not ruin their faith in god. If my child decides to stop believing god, I want them to come to that conclusion on their own.

    Best answer: Al Gore was not silent on Global Warming. Here is proof.

    Quote by Will Happer, Princeton University physicist, former Director of Energy Research at the Department of Energy: “I had the privilege of being fired by Al Gore, since I refused to go along with his alarmism....I have spent a long research career studying physics that is closely related to the greenhouse effect....Fears about man-made global warming are unwarranted and are not based on good science. The earth's climate is changing now, as it always has. There is no evidence that the changes differ in any qualitative way from those of the past.”

    That was 25 years ago, 1993. He was also instrumental of Jimmy Hansen's speech on the floor of Congress in 1988. He was also an advocate of an Ice Age back in the seventies. Thereafter he morphed into a Global Warmer.

  • Why do so many jobs demand multi-tasking our attention, when we can only listen to one thing at a time?

    Like fast food: You have customers in your ear interrupting you with things while you're trying to listen to one customer, and then your boss/co-workers are blurting things out to you, and everyone wonders why such a simple job gets orders wrong all the time lol. We're not wired for multiple conversations... show more
    Like fast food: You have customers in your ear interrupting you with things while you're trying to listen to one customer, and then your boss/co-workers are blurting things out to you, and everyone wonders why such a simple job gets orders wrong all the time lol. We're not wired for multiple conversations and distractions! Yet this job demands attention on everyone and everything at once. Same with some office positions and whatnot. You're trying to do one thing, and people are coming at you, interrupting your concentration with all their needs and demands. We're not wired for this! I could go on with different job examples, but it's so strange that we're wired one way & expected to perform another. Why is this?
