Sci & Tech Reflection

This flight unit was very fun and educational. My class learned a lot from this flight unit, like how to build a tissue paper hot air balloon. To make a hot air balloon we needed six sheets of tissue paper, scissors, and glue, and at the end some tape and wire.

We needed to stick two sheets of tissue together then another two sheets and another two sheets, like a sequence and let them dry. Then we stuck them all together, and then we cut the extra tissue paper off to shape it and it round. We glued all the pieces together and put at the top of a round sheet of paper on the inside of the balloon. Then we put some tape on some wire and put it in the bottom of the balloon where the air goes in and folded a little bit over the round wire put some glue and let in dry.

Then we tested our tissue paper balloons out with some warm air to check if there were any holes to patch up, if there were any holes we would patch them up or cover them with a decoration. The reason there were not supposed to be any holes is that the balloon would not work very well and have very little take off time and poor lift off. The balloon my partner and I worked on was very well designed. The scientists who came to guide us demonstrated some of the properties of air (which we already knew a bit about because we did a couple of class experiments) and how these affect flying devices. The properties of air are that hot air rises and cold air drops. The principles to make a plane take off are lift, drag, weight and thrust which help a plane move / take flight or land. You can check out our balloons in the blog: http://www.gr6flightballoon.blogspot.com/ Actually that part of our science unit was cool. We had the chance to show all of activities in our class blog. We even had the chance to make comments and give suggestions on what we were learning.

We also visited the Air and Space Museum which was a great experience to look at some airplanes and learn about the history of the hangar. We also got to go in groups of four to build kites with Ms.Rambaran’s class. I was fortunate to work in a team that was dedicated and had a great sense of humour. We built a diamond kite and we are convinced that if the string was stronger it would have taken off much more successfully.
