This week Sixth Class had to put their engineering caps on and complete the EGG DROP CHALLENGE!!
The objective was to design a landing craft that would protect an egg from cracking or breaking from a high fall.Each student had to design, build and test their landing craft for homework.They made them using a variety of materials, such as, show boxes, pillows, plastic bags and popcorn. Many students also made parachutes and wings to help their landing craft.
We had great fun testing them and checking to see whether our eggs ‘survived’ the drop. In the end, we only broke three eggs!
Have a look at some of our EGG-CELLENT landing crafts!
During Engineers Week 2020 , first class were set the challenge of designing an escape route for Rapunzel. They used the engineering design process to firstly think about and then draw a plan of their ideas. After that they used some of the classroom equipment to build their ideas in groups. Take a look at some of our ideas and inventions!
We constructed a Geodesic Dome in class. First, we made 3D structures using toothpicks and Plasticine to see which structure would be the strongest to use. We found that triangular structures worked best. We made lots of triangles using rolled newspaper and taped them together. We had to make sure that each one was the same length. We attached an oxygen supply to our Dome. We found out lots of fun facts about life on the moon!
Sixth class were busy this week designing and making their own electric quiz. They had learned about circuits last week and put that knowledge into practice to make their own quiz. Fourth class had the opportunity to have a go at the quiz!
Make hole in lid and put straw through and secure.
Cut other balloon in half and tape to the bottom of bottle.
Result- When we pulled the balloon at the bottom of the bottle it did not work. We replaced it with a rubber glove. When we pulled the glove down the balloons expanded.
Conclusion- When we breathe (inhale) the diaphragm pulls down making the chest expand. This causes air to be sucked into the lungs. When the diaphragm relaxes the air is pushed out of the lungs (exhale).
