*********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?

Well, The half-life of uranium-238 is about 4.47 billion years and that of uranium-235 is 704 million years. And it can damage lungs, liver, bones , fettos, make deformation in babies and cause several diseases like cancer.

************Can a fly or temperature of a corpse help in finding the time of death ?

Yes , because with the temperature you can determnie the exact time of death using the temperature of the environment and you can also determine the time of death because flies go to body whne it is decomposion and have several baceria on it.

*********Why a painting of the Dutch painter Vermeer de Delft, titled Christ at Emaus, was withdrawn from the Boymans of Rotterdam Museum in 1945 after a painter named Hans van Meegeren declared publicly that the painting was a forgery?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?

Well, well, he played with nazis, art experts, italinas, museums, other and at the end he make himself get discover. The painting was discover a forgery because he said it, and to prived that he really did the copy, they made him made aother copy of the peace of art and dicover that he actully did a real Vermeer. He was send to prision for a yeras because of his health condition and died in 1947 and the age of 58.

Reflection time.

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

The art story because I really like to read about those kind of topics and things, but I loved science als, and I loved to investigate about problems in the world so I really like the activity.

******Would you recommend the use of a WebQuest to learn Mathematics or some other Science subject?

yes, of course Linda, I realy like giving aswer to this kind of questions.

hacer el proyecto de lo de el caso fue algo muy divertido, ya que estubimos un buen rato tratando de grabar las escenas porque no sabiamos que lo podiamos haver en español, pero en fin espero que nos des puntos extras por el esfuerzo xD,

Hacer este projecto en mi opnion es algo informativo y que nso ayuda a por lo menos poder relacionar algo de lo vemos en clase en algo mas real.

vacations!!!

Estas vacaciones fue de total relax, porque toda la semana me la pase agusto en mi casa durmiendo y viendo tele, y mis amigas me decian vamos al mar, vamos al cine, hay que salir, y yo preferi quedarme agusto acostada toda la semana hasta que mi mama se arto de verme acostada y me queria poner hacer algo en la casa y mejor me fui con mis amigas a dal la vuelta, y a divertirme un rato. La verdad no hice mucho en esta semana pero era lo que necesitaba. xD

La verdad a mi me facina todo lo relacionaod con investigar y buscar y eatr detras de algo hasta encontrar la respuesta, aunque aveces no lo paresa. Para mi este proyecto es bueno , no lo voya negar ya que pone a pruba muchas cosas y los mas importante porque Lindo nos enseña todo eso de las devivadas y senos y consenos. ¬¬, peor en fin me gusta el poryecto aunque si em da flojera ponerme a grabar y hacer dialogos y todo eso, pero creo que es divertido.

bueno, esta semanas an sido muy pesadas en todos los sentidos porque hemos estado haciendo examnes de hasta lo que no, pero creo que esto nos a ayudado muchisimo a ya ponernos las pilas en todo, por que por ejemplo en mi caso el ceneval me va ayudar a hacer mejor mis examnes de admision en las universidades a la sque voy a aplicar.

TABLE TIME

xD

1. What is the Newton’s Law of Cooling?
It's a method used to determine the time of death of a murder's victim by using the body temperature and the environment temperature.

2. What variables in your problem correspond with the variables in the Newton’s Law of Cooling?
the temperature of the environment, the body and the time the temperature was taken.

3. According to this Law, at what time approximately the death happened?
Between 8:48 PM and 8:55 PM

4. How does the room temperature affect the time of death?
We have to be very precise when taking the temperature of both; the body and the environment, because with one small change in the environment an inocent person can be found guilty.

5. How does an illness (e.g. fever) affect the time of death?
Because it changes the body temperature.

6. How exact is the approximation of the Newton’s Law of Cooling for predicting the time of death?
It can be very accurate in most of the cases, but you need to have the correct information, because if the victim is sick or the environment is constantly changing this method won't be useful.
