Passos do Método Científico
Por Oliver Smith
O método científico é um processo constante: uma descoberta pode levar a muitas outras perguntas que, quando investigadas, podem levar a mais respostas. Além de um resumo das principais etapas do método científico, há sugestões de atividades para que seus alunos se envolvam em pensar sobre ciência no mundo real.

Storyboard Descrição
scientific method comic: See the steps of the scientific method for the discovery of DNA's helical shape
Texto do Storyboard
- Part of the Scientific Method
-
- ?
- Example
- DNA has four bases.
- Question
- Avery, MacLeod and McCarty discovered that DNA was likely to carry the genetic information. They did not, however, know the shape of the DNA molecule.
-
- Hypothesis
-
- Crick and Watson hypothesized that DNA had a helical (spiral) shape.
-
- I think __________ will happen.
-
- Prediction
- ?

-
- If the form of DNA were helical, then its X-ray diffraction pattern would be X-shaped.
- I carried out an experiment using X-rays to look at the structure of DNA. Using this image I made, we can work out what the structure is.
-
- Experiment
-
- Rosalind Franklin was carrying out research at Kings College, London. She looked at the structure of DNA using X-ray diffraction.
-
-
-
- Analysis
-
- The images were shared with Watson and Crick who analyzed the images and discovered that the pattern matched their hypothesis and prediction.
