(13) Scientific Methods Notes - We took Cornell Notes about how scientists think and use evidence to support any explanation they create. Focus Question: How do scientists know an explanation is a good one?
(12) Chromatography Lab -
- Research question: Are markers made of only one color dye/ chemical?
- Hypothesis: [What do you think is the answer to the research question and why?]
- Materials:
- Filter Paper Strips
- Markers
- Cup
- Water
- Procedure:
- Draw a dot on the strip of filter paper 1 cm above the bottom
- let the bottom of the filter paper touch the water
- Allow the water to soak up the paper through capillary action until it is close to the top
- Observe the ink move up and separate
- Results: [create a data table and illustration of your results]
- Conclusion [Did the results support/ not support your hypothesis?]
Through this lab we found many markers are made with a mix of different dyes and colors.
