everyone this is 1st period this is opptional but you still have to read it u could do the expiriment for extra credit but then tell me what happened when you were doing the expirement

our lesson is weather watching
you need : food dye,a glass bottle,a bowl,water,narrow drinking straw, playdough,a cardboard strip 12x5cm

directions:1. fill the glassbottle with cold water.add some drops of food dyeto the top of the water,then top up the bottlewater untill it overflows.

2.roll some playdough around the straw about 10cm(4in)fromthe top.becareful not to crush the straw when you do this.

3. put the straw in the bottle.push the playdough around the top of the bottle,so the bottle is airtight.the water should rise up the straw
4.stand the bottle in the bowl filled wth cold wter fr a while. the wter in the straw should fall.now take the bottle outside somwhere safe




what happends: when the bottle is warm the tempurature forces the water up the straw.and when its cold it the water goes back into the straw leading to the bottle

wow!! that was some nice science! another thing you learned on the experiment is the capillary action that pushes the water up the straw.

another point learned in the whole experiment is how hot and cold temperature affect our daily life. one example is that when weather is hot our house expand and when weathers are cold it retracts. hope this might add up for some science application! ^^
