UNIT 1



 In the first day we did a marshmallow competition the objective was to do a macaroni tower and put the marshmallow on top. The biggest tower was going to win.








After we did a Hypothesy of the bean investigation. The bean invastigation was 2 beans one was growing in the dark the other one was growing in the light. This is a copy of my Hypothesis.                                      Hypothesis

If we put the bean seed in the dark it won’t get the energy from the sunlight that he needs to grow if we put it in the light it will get the energy that it needs from the sun.Beans use the sun energy too grow their own food, this process is called photosynthesis. The bean gets the energy from the sunlight. If we put it in the sunlight the soil will get the energy from the sun, the energy that the soil needs and that will make the soil strong.

After the hypothsis we did a Wanted poster of a famous scientist .
This is a copy of my wanted poster.


            WANTED !!!         WANTED  !!!                                                                                              
 Rosalind Franklin
 WANTED: For new discoverys about DNA’s
  Rosalind Franklin was born in July 25, 1920 in London. by the age of 15 Rosalind wanted to be a scientist. She studiyed in Newnham College. In 1938 she started to study chemestry. In 1946 she went to a Laboratoire Central in Paris, that she worked with Jacques Mering . She did a X-ray diffrection and she used it to create images of a crystalized solid. In 1951 Rosalind started working in King’s College London, Rosalind had a student her name was Raymond Gosling. When Rosalind and Raymond Gosling where studying DNA structure with the X-ray diffrection, they made a big discovery. They discovered that there were two forms of it, a dry "A" form and a wet "B" form, one of their X-ray diffrection pictures of the "B" form of DNA, known as Photograph 51, became famous. The DNA was called deoxyribonucleic acid. When she finished her DNA project she went back to London. She started studying in  Birkbeck College, where she was working on tabaco virus. While working on this project, she discovered that she was with ovarian cancer. So she died in April 16, 1958 with 37 years old.

                                                                      UNIT 3

We just started unit 3 and the first thing we did was write a hypothesis. Because we are going to do a experiment that works like this:
We are going to have different cars. One car weiths 50g and the other one weiths 10g. So which one is going to go down the ramp in a faster speed. So we needed to write a hypothesis about that.
I thought what was challenging was the cells test.
I liked the experiance of the car with maore mass will go down the ramp in a faster speed.
