How many years will be required for a radioactive material like Uranium to disappear after a reactor explodes like in the terrible nuclear accident occurred in Chernobyl and what are their long-term effects?
Like 1520 million years approximately, their effects are unhealthy borned child, deformations on living beings, and contamination in the environment.

Can a fly or temperature of a corpse help in finding the time of death ?
Yes, there are methods like Newton's law of cooling, in which the temperature of the body can determine an approximation in the time of death, plus also by counting the number of flies around the body, you can have an estimated time also.

Why a painting of the Dutch painter Vermeer de Delft, titled Christ at Emaus, was withdrawn from the Boymans of Rotterdam Museum in 1945 after a painter named Hans van Meegeren declared publicly that the painting was a forgery? How was it proved that it was really a forgery?
They used a technique in which they applied different pigments and methods, to calculate the years that it had, and they discovered it was fake, it wasn't that old.

Reflection time
What do you think is the most important thing you learned through this WebQuest?

Well, it was fun to learn how to mix technology, murders and math, to learn an actual calculus application via internet. It was different, but original.

Would you recommend the use of a WebQuest to learn Mathematics or some other Science subject?
It depends on the subject, but for this type of cases like murder we wrote, yes.

The Math Detectives

One murder, many problems, too many suspects, one guilty, math detectives did it again!

We got together, and we recorded our video in which we solved the mistery using Newton's way. We did a lot of teamwork, and we finally finished it.

We had a lot of fun doing it, we went to marion's house, to our school and to the hospital, we had a few problems but at the end everything got together and we succeded.

In this free week I went to Atotonilco, to "misiones", and it was awesome, we helped all its citizens, and made them get closer to God, and away from drugs and alcohol! I recommend this type of activity to everyone, because it helps you grow as a person in a huge way..
