Zinātniskā Metode Soļi
Autors: Olivers Smits
Zinātniskā metode ir pastāvīgs process: viens atklājums var radīt daudz vairāk jautājumu, kurus pētot, var iegūt vairāk atbilžu. Papildus zinātniskās metodes galveno soļu kopsavilkumam ir ieteiktas aktivitātes, lai jūsu skolēni iesaistītos domāšanā par zinātni reālajā pasaulē.

Montāžas Teksta
- 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.
