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!
We have been learning all about the signs of Spring and the changes that happen at this time of year. We loved going on a ‘Spring Hunt’ around the school grounds in search of signs of Spring. We found lots of new things growing, such as seedlings, buds, blossoms and flowers. We saw new leaves growing on the trees. We saw lots of birds flying around but did not come across any nests, so we will keep an eye out for that and more signs of Spring over the next couple of months!
5th Class Room 7 have been extremely busy researching information about the human eye. We learned all about the human eye, it’s parts and their functions. After that, we split into groups and researched topics relating to the human eye that are of interest to us; Optical Illusions and Braille. We also completed 3 surveys on the topics of eye colour, glasses and contact lenses and what you could see in one particular optical illusion.
We have been experimenting and testing the force of water on objects by investigating things that float and sink.
To begin we collected a variety of items from around the classroom to investigate. As a class we predicted which items would sink and float in water. Next, in our groups, we took turns to test the items to see if they would sink or float. Lastly we sorted the items into two groups; sink or float and we recorded our results.
The second activity we completed was ‘Design a Boat’. Firstly we experimented with a ball of plasticine to see if it would sink or float and if changing its shape would make a difference. Then in our groups we tried to use the plasticine to design a boat that would float. If we were successful we tested our boat to see how many ‘passengers’ (dried peas) it could carry. After a few attempts some groups were successful! 🙂
The last activity we completed was an experiment called ‘Dancing Raisins’. We predicted what would happen to the raisins in water and in soda water and then observed the differences between the two types of water. We were amazed to watch the raisins begin to ‘dance’ in the soda water! Why do you think this happened?! 🙂
This week we worked together to plant all of our seeds from Incredible Edibles! We now have such a variety of lovely fruits and vegetables growing in our garden. We sowed strawberries, potatoes, chives, lettuce, spinach and turnips. We will be busy caring for them over the coming weeks and can’t wait to watch them grow!
Using blocks, paper, books and crayons to test we designed bridges to see which ones were stronger and could hold the most amount of crayons. We manipulated our structures to increase their strength by folding the paper used, using double layers of paper, creating arches and structures for extra support.
The material from which a structure is made is important but you can strengthen a material by changing is shape. Bridge designers often use different shapes for example: arches and triangles. The curve of the arch spreads the load on the bridge and makes it stronger.
