homework 1

1. The switch, is an everyday tool that we use. And, the simple machine that is used is the lever. The fulcrum is in the middle of the switch while the effort is on the side of the switch while the load is...to turn the switch on!

The lever helps us by reducing the amount of effort needed for the job or or it can move the load a longer distance depending on where the fulcrum is.

2. The door stopper is a very effective simple machine that is used to prevent the doors from moving. It is actually an inclined plane that is wedged right between the floor and the door which in turn, will prevent the door from moving!

3. The can opener is a ingenious device that allows you to open up your cans with ease. It has gears inside which turns the blade inside when you turn the handle.

4. there is a type of ceiling fans that need you need to pull some string to change the speed which, uses pulleys!!When you pull the string, you also pull something inside the fan to change the speed!

3 days at school

When I woke up on the first day of this go-back-to-school-on-the-holidays programme, I was full with dread as did'nt know what to expect. So when I entered the classroom, I was very suprised to find the tables and chair arranged into a arena! Well, to cut it short, we played a short game called charades (I had to act out the phrase farting fear pie) I felt little embarrassed!

The next day, we did maths. Mrs Chien also introduced more on visualisation problems which we did throughout the day. At first I had a little bit of problem trying to visualising the problems, but I managed through.

The last day we did science. Mrs Chien prepared 2 experiments for us. The experiment that I did was based on the topic light. But no matter how we placed the torchlight, the datalogger still did not pick up any signs of light. But then the aroma of the pizzas wafted into my nose as it was brought in. We probably could have been in the guinness book world records for the fastest class party which lasted only for 12 minutes!Imanaged to eat 3 slices of pizza and gulped down lots of pepsi,coke,fanta,and juice. (I got a stomachache after that) What I do conclude that, those three days were the best!!!!
