We learned about different kinds of materials and their properties. We carried out an experiment to test some materials. We tested a tennis ball, a sponge ball, a ball made from plasticine and a ball made from rubber to see which one would bounce the highest. We wrote out the experiment and carried it out three times to make sure that it was a fair test. We discovered that the tennis ball was the bounciest ball.
We did some more experiments today. Click on the link to watch the video.
Stand with your back and heels against a wall. Drop a coin on the floor in front of you. Can you pick it up without falling over?
Stand with your feet apart, one foot, shoulder and head all touching the wall, and raise your other leg. Dead easy- or is it?
We’ve been enjoying science week this week. We’ve done lots of experiments.
We put an egg into vinegar and we’ve been watching what happens. The vinegar erodes the egg shell.
We put ‘Mentos’ sweets into Coke to see what happens – it exploded!
We put raisins into Seven Up to see what would happen. The gas in the Seven Up makes the raisins rise and fall.
We put warm water on ‘Skittles’ sweets to create a rainbow.
We recorded all our experiments in our copies.
We loved doing our experiments because we could eat and drink most of them when we were finished! Click here to see our video.
We learnt about a nest in school yesterday. There was a cracked egg inside.We learned about the life cycle of birds.Ms Ferguson showed us pictures of birds and when they grow up. There was blackstuff in the nest that looked like shells. We reckoned it was a blackbird by the eggs. The bird was very clever by using mud to stick it together and used leaves as bedcover.Their eggs are a light aqua colour.The sticks were tucked in very well . It shows that blackbirds are very clever . But sometimes they are very cruel to their speicies .The male bird doesn’t help build the nest at all ,the female does all the work.Sometimes the dad kicks the baby birds out of their nest . It can also take ages to crack open the egg. We watched a video where a egg hatched at x30 the speed. They also have a tooth to crack open the egg.It was great fun !!!! and NEVER go near or disturb a nest!!!!!!!Thank you BY Lucy Andrews
Using books and A4 paper the class had to design a bridge that toy cars could drive over. If you used a single piece of flat paper the bridge collapsed under the weight of the car. You were not allowed to use anything other than paper to strengthen the bridge.
Working in pairs the children came up with lots of successful designs. These included:
- Using several pieces of flat paper.
- Folding a sheet of paper 2 or 3 times.
- Folding up the sides of the paper.
- Making an arch (using two pieces of paper).
Our class is full of scientists and engineers.
