V1 skittles lesson

Planning

- Doing research?

- Research question 1

• Taste
• Steps of doing research

- Research questions 2 & 3

• making graphs

Learning goals

1. you can apply the different steps of scientific research
   
2. you understand the basics of taste
3. you can draw a correct graph 

Doing Research

• same format

• Finding the truth

• Others have to find the same results

Strict is een woord dat de leerlingen niet zullen kennen, kan je het vervangen met een versimpeld woord? 

Research Question?

You would like to know the answer to the research question

examples: 

1. Is there a taste difference between the different colored skittles?
   
2. Do the bags have the same amount of skittles?
   
3. Are the different colored skittles evenly divided in the bags?
   

The question you want answered.

Dit is een moeilijke zinsopbouw. 

Misschien: You would like to know the answer to the research question

Distributed is lastig, divided is een woord dat ze wellicht wel kennen. 

Taste

Mouth:

Sweet, Sour, Bitter, Salty and Umami

Nose:

Complex smells lead to  complex tastes

You can taste everything everywhere

Hypothesis

• Possible answers on research question
  
• Based on theory
• What answer to your research question do you expect?

3e punt toegevoegd

Write down the hypothesis for this research question: Is there a taste difference between the different colored skittles?

Method

A detailed description of how you want to do your research.

- As detailed as possible

- The next person has to do exact the same thing

- Don't forget to think about how you want to store your results

Ik denk dat het voor leerlingen best moeilijk is om al een methode te schrijven. 

Misschien kan je het filmpje van de peanut butter and jelly sandwich nog laten zien, zodat het duidelijk is dat ze echt heel duidelijk moeten zijn in hun werkwijze. 

Duurt wel 7 minuten

Anders kan je misschien een volgorde slide maken. Dat is een CLIL opdracht waarbij je wel alle zinnen geeft, maar leerlingen moet hem zelf in de goede volgorde zetten:

Eat a colored skittle, one at a time. 

Rinse your mouth with water between eating the skittles.

Grab your materials.

Eat a colored skittle, which is another color. 

State if the skittle tastes different than the other skittle. 

(State is denk ik een te lastig woord, maar kan je eventueel toelichten)

etc.

Place the steps in the correct order for the research question: Is there a taste difference between the different colored skittles? 

1.

2.

3.

4.

5.

Eat one colored skittle

Rinse your mouth with water between eating the skittles.

Grab your materials.

Eat a different colored skittle

Say if the skittle tastes different than the first skittle. 

Write the methods for the research question: Is there a taste difference between the different colored skittles?

Material

A list of all the things you need for your research

- As detailed as possible

- Also say how much you need

For example:

2 bags of skittles

Which materials do you need for the question: Is there a taste difference between the different colored skittles?

volunteer?

Results

- A clear overview of the experiments with the use of graphs and tabels

- NO opinion on/interpetation of the results

Conclusion

Discussion

Answer research question

- True/False hypothesis

- understanding of the resulst

- Discuss your findings

- Name the improvements

Interpretation is een te moeilijk woord, hou het simpel

All skittles taste differently the same

1. True
2. False

Breaking news!

one more time!
