Our science teacher said that if you finished in your experiment, you need to do another experiment it is the Skittles experiment. I and khush and khyle done so cool we take photos on it it was so cool the skittles turning to a rainbow. It was so good, our teacher said that if we are finished we need to post it on the blog and show it to the teacher before you published.
Aim: To separate colours from skittles by using chromatography.
Definition: Chromatography is a method of separating out materials from a mixture.
Eg. blood, ink, drugs,
Materials:
- Petrie Dish
- Water
- Skittles
- Green skittle
- Two blue skittles
- Orange skittle
- Yellow skittle
- Red skittle
Steps:
Step 2: Put All six skittle in the Petrie dish.
Step 3: Spread the skittles out evenly in the edge of the dish.
Step 4: Put some water to the top of the Petrie dish.
Step 5: Step away and watch it make colour
Step 6: at the end of the experiment you can eat the skittles that were in the Petrie Dish.
Step 3: Spread the skittles out evenly in the edge of the dish.
Step 4: Put some water to the top of the Petrie dish.
Step 5: Step away and watch it make colour
Step 6: at the end of the experiment you can eat the skittles that were in the Petrie Dish.
Conclusion :
I've learned about what kind of material we need to make this rainbow skittle colour in the water. When we start to put the water on Petrie Dish, the water slowly changing to a rainbow colour. Then the skittles slowly no more colour on the bottom only at the top. Then after it is done the water is so colourful and the same as a rainbow colour.
Hi JV, your procedural writing skills are increasing JV, you have included all the main headings and the information you have included in the "steps" is clear and easy to follow. I am amazed at how the colours of each skittle stayed within a triangular shaped area in the petrie dish. I wonder why that happens? How could we find that out? Keep up the great work JV.

Hi JV, Well done. Your writing and the way you have set it up looks great. Keep asking lots of inquiring questions. Science is all about finding the answers to question. Keep up the great work.
