Could you plz suggest an easy example of investigatory project in science.?

An easy science fair type project that you can put together would be liquid chromatogrophy.

This involves separating the different colors from a dye or liquid color with a solvent.

The easiest thing to do is to take different brands of washable markers. Say…Crayola, Sharpee…etc.

Put a horizontal line on a strip of paper and BARELY put the bottom of the strip into water.

After some hours, the water will have soaked up to the top of the strip of paper and taken the dye from the markers with it.

The black markers will have separated into all of the different colors which make up black.

Try it with all the different colors. See how red, yellow and blue (primary colors) differ from orange, green, and purple (secondary colors).

How do different brands differ from each other? What happens if you use a non-water soluable marker?

by making use of making use of the right practise of any digital pupil you may layout the device observed as sea shore eagle. this would have 2 forms of sensors. The circuit for water point indicator could be utilized. One sensor would be continuously immersed in sea.( it is in water) the different one would be in the shore that isn’t touch the water. the present forms of sea roughness can’t be even warned by making use of Buoys. This device whilst it is asserted with siren can furnish the warning in 2 situations. If the sea water reseeds and if it comes out of the shore from its commonly used decrease. So the folk can circulate to a safer place nicely in develop formerly important incidents take place. i’m the single that issued the warning to community T.V 2 hours formerly Tsunami struck our coast. yet they have surpassed over my warning.We lost the life of countless 1000’s.
