“How do you convert pounds to kilograms?”
People often email me this type question. There are all sorts of charts and calculators and formulas, but the easiest way is…
1. Go to Google.com.
2. Type in “convert X pounds to kg”.
3. Read the answer. It will convert it for you.
(Of course, you could just multiply number of pounds times 0.4535923744953. But who wants to do all that work?!)

When The Science Project Data Doesn’t ‘Look Right’
A student doing the “A Slice of Ice” experiment emailed me last week with some concerns about his results. According to his calculations, his results did NOT prove what he expected. He had hypothesized that pieces of ice with the greatest surface area would melt first. His data did not back that up, and he was concerned that something was wrong.
I was also concerned, because his hypothesis was correct. If the amount of water frozen remains the same, then ice with the most surface area melts the fastest. So I asked to see his numbers.
And once again, this young man was correct. He had made an error entering his data, and had calculated the surface area incorrectly. When he put the numbers in the correct places in his spreadsheet, his data proved his hypothesis to be true.
This young man learned two valuable lessons: if something doesn’t look right, check it! Follow your instincts. And always double check your data.

How do you convert ounces to ml?
“How do you convert ounces to milliliters?”
I get conversion questions like this all the time. There are charts, calculators and formulas all over the internet, but the easier way is…
1. Go to Google.com.
2. Type in “convert X ounces to ml”.
3. Read the answer. It will convert it for you.
(Of course, the real answer I should give you is to multiply the ounces times 29.57. But who wants to do all that work?!)

Finding the Average for a Science Project? We’ll do it for you!
Fourth grade science project question: “I’m a mother of a 4th grader who is currently working on his science project. We did the project and it was interesting what the results were. The only thing I can’t figure out how can we figure the average numbers at the end of the trials? How do you find the average?”
Finding the Average
This was an easy question for me to answer. Since this mom was one of our customers, I just referred her to the spreadsheet included with her project. All she had to do was put in the numbers, and the chart (like the one in the picture) was generated automatically. We have formulas in the spreadsheet that do all the calculations.
That’s what 24 Hour Science Projects is all about!
