Our Jelly Bean Fair Testing Investigation

Hey, this is Jamie and Sanford on the blog this week, talking to you about this weeks science experiments using jelly beans :o

The experiment was to see if we, the class could dye a piece of white cloth using

JB's (jelly beans), clear vinegar, a jar or clear pot of luke-warm water and a white cloth.

It works by filling a jar with luke warm water, then you apply the 'six' jelly beans, either all of the same colour or all different colours. For instance, the picture above has all different coloured JBs. The next step was to add about a lids worth of white vinegar, then you guessed it, add the white cloth.

We did the normal experiment which is seen above, then the second time we

did it, we had to change one variable, like the colour of the jelly beans or the temperature of the water. Now if you were intelligent enough visually, you should have seen a difference but you're probably not, so that's why we did another test,not! We did another test because its a part of FAIR TESTING which is the key to all good science investigations. You could change one thing which you decide on. Now this was where most people saw a great colour burst in their cloths.

We had a work sheet to fill out during our jelly bean investigation to see what we all observed during our interesting but fun time.

Well I hope you enjoyed reading about Room 18's fun week
