Rubber tube car descreption

I made two cars for rubber tube car competition. The first one didn't work. I thought it would work, but it didn't beause the wheel of the car were unstable because it was bottle caps and it was not big enough and there was not enough force to make it go 2 meters. I liked that it was very light in weight and i made a wall so that the rubber tube can hit it but the force was too small. The second car was also very small Hotwheels car and i just taped the tube in the car, so i was disqualified and i didn't actually did any hard work on that one and it went 20 meters flying. If i were asked to make a new car i would change the whole car and make better wheels with rubber traction and pull the rubber tube hard enough so that it can go 10 meters and fixing the tube in the correct place is also important. 

Car V/S Ballon and Velocity V/S Time

Today we did a activity regarding Velocity of a car and the time taken by the balloon. The activity was fun and we had to release a balloon from 4.32 meters it should hit the car moving down at a Velocity of 1.92 m/s. First we found out the time it takes the balloon to hit the ground by doing certain calculations and it was found out to be 0.94 s and then we found how far the car should be in order to get hit by the balloon, it was 1.8 m. If i had to mark our performance from 1-10 then i would give it a 7 as we were unable to hit the balloon on the car because it was hard to make the car to go in a straight line and release the balloon at the same time, that's why i will give it 7/10. 

,"Measuring without accuracy or precision, is like trying to light a candle in a Hurricane"

Today we had a class in which we learnt the importance of  precision and accuracy by making a house with paper.  The importance of precision and accuracy can be seen in this qoute,"measuring without accuracy or precision, is like trying to light a candle in a Hurricane". without precise measurements we  will never be able

 to arrive at a correct answer and will always be one step away from perfection. the idea is specifically conveyed by a candle which will never lighten up unless the right conditions are provided. just like trying to light up a candle during a hurricane will be as in vain as trying to arrive at a solution using incorrect/inaccurate data.

 

How do Stacking of cups relates to the amount of team work needed in Science

Stacking of cups relates to the amount of team work needed in science as it showed how a team should work. It would have very difficult if we were asked to do it alone. Even the great World researchers needed a group to make something.

Making a elegant shape with pieces of paper

Pieces of paper cut into Random shapes seems to make no sense at first but if we we join the pieces we can find it like a puzzle and we can get a perfect shape from it and it can be a rectangle or square. We did this activity in our class, we were given a few pieces and after some struggle we were able to make a perfect square from it.

making pyramid with paper glasses

Making Pyramids with paper glasses is very interesting activity. We make it by a rubberband with 4 threads tied to it and there are 2 partners holding 2 threads with both hands and then lifting it by stretching the rubberband and putting it over the other cups and making a pyramid.
