This week in Science we were designing and making bridges! The bridges we made had to have the following features:
(1) It had to carry a span of 50cm. This means the bridge had to stretch across a gap of 50cm in one go.
(2) It had to be strong enough to carry a load of 1kg.
(3) It could only be made using newspapers and magazines.
We found it difficult in the beginning but we made some amazing bridges in the end! Take a look at some of our bridges below!
We are about to start the novel Holes. The main character is called Stanley Yelnats. Stanley Yelnats name is a palindrome! A palindrome is a word or phrase that reads the same backwards as forwards. We have had some fun with palindromes. Can you guess what they are?
We used cars and different materials to find out the effects of each material on the speed of the cars. The materials we used were tissue, tinfoil and a tea towel. We discovered that the car moved slowest on the tea towel.
Then we used the cars with ramps to see how the angle of the ramp impacted on the speed of the cars. We found that the car moved fastest on the steepest ramp.
Science is fun!
