The shape of the helicopter rotor blades make it spin when dropped from a height. Gravity pulls the helicopter down. The air resists the movement and pushes up each rotor separately, causing the helicopter to spin.
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 are taking part in Science Week this week. We have been learning all about the work of 5 scientists on http://imascientist.ie/ .
There are four zones and we are taking part in the ‘Light Zone’.
We will be voting once this week for our favourite scientist, and every day next week. Today we voted to keep Dervil Cody in the competition. She took part in a ‘Live Chat’ with us today and we really enjoyed it. She works creating holograms that can tell if air is polluted.
The winning scientist will win €500.
We were all able to log-in and ask Dervil questions about her work. She answered all our questions and we learned at lot.
We received our growing packs yesterday from Innocent Smoothies. The packs contained seeds, cups, compost and growing instructions.
There were 3 seed packs, Cress, Spinach and Peas.
We had great fun today planting our seeds! We each got a pot and we planted Cress, Spinach and Peas. The Cress was the most popular, then the Peas and finally Spinach.
We also got a copy of our growth chart and we look forward to measuring the seedlings when they germinate.
We worked with chocolate because we could easily have it as a solid (block) a liquid (melted) and a gas ( we could smell the vapor/gas)
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.
