STRAW WAVES ENGLISH 31MB.wmv
This is the most amazing science model. you just need a bunch of straws and some sticky tape to make these wave models. cut 3m of sticky tape and keep it on the floor with the sticky side up. mark the mid points of straws and place them on the middle of the sticky tape, uniformly, every straw 2cm from the previous straw. leave about 5cm of tape from both the ends to act as handles and stick about 80 90 straws in this manner. now double the tape up. you can see that now the sticky side is below. this way straws will be sandwiched.
Between the two layers of the sticky tape and they will be adhered very strongly to the tape. cut the doubled up tape and the straw model is almost ready. remove the tape from the floor and you can this girl lifting the straw waves. ask a friend to hold the other end and you give a tap from one end, you will see a reflected wave coming from the other. your friend can try it too. if you hold the straws loosely then the speed of the wave becomes slower.
STATIC STRAWS ENGLISH Great fun on a cold, dry day!
This is a beautiful experiment which demonstrates static electricity. you will need plastic straws, some woolen cloth and thread. first take the straw and punch a hole at one end of the straw. make the hole in all 10 straws that you have. you can use colored straws also. then a 20cm long thread and tie it at the end of the straw. do this in all the 10 straws you have. bring all these threads together, bring them together and tie a knot in all the ten threads together. tie the knot in the middle of gathered threads. now rub all.
These straws with a woolen cloth. when you lift thee you will see magic. all the straws have been charged with same polarity and hence they repel. this is beautiful demonstration of static electricity. if you give them a slight twist, they start rotating lie a chandelier. if you bring you hand near them, they get attracted to your hand. now hold the straws together and rub it with your hand and you can see that they have been discharged. now they are not repelling. to repeat the same repulsion, rub the straws with the woolen.
Model of lung
Sound of bubbles popping Ever felt out of breath Ever wanted to go that extra mile Well now you can, with a little help from us. Hi, my name's Steve and I'm from the Questacon Science Squad and today I'm going to show you how to make a model of a lung. What you'll need is a pair of scissors, two balloons about 30 centimeters in diameter, a straw, a rubber band, a piece of plasticine about two centimetres across, a pencil and a plastic bottle about 600ml large. First what you'll need to do is get your balloon and cut off the neck, like that.
This is now going to act as our diaphragm. Next you want to get the plastic bottle and cut the base off, like I have done here. Now get your diaphragm and stretch it very, very tightly over the end of your bottle. Now, this can be a little bit fiddly, so I've prepared one earlier. Now get your other balloon and put the straw in through the neck and tie it off tightly using your rubber band. The balloon is going to act as our lung and the straw is going to act as our wind pipe.
Great. Now what we're going to do is we are going to get the pencil and put it through the centre of our ball of plasticine. Then we get our straw and we put it through the hole we've just made and pinch it off at the ends so that no air can escape. Now you want to get the balloon, squeeze out all the air and feed it into the top of your bottle. Push it all the way down and then once you've done that, squeeze off the sides of the.
