Day of action
Home up

 

 

 

 

On the 7th March it was all action in St. Brigid;s school with the energy fun day.  They were several stations and each one explored various aspects of energy.

Mechanical Energy

  There was an energy funday in the hall. I was in charge of table 1 and was showing people three K-Nex  models and some water energy. I started on an  elastic band powered car that you wound up  at the wheels and it drove off. The car used kinetic energy and had potential energy in the wheels. Next I showed everyone a crane. There was a handle on the side which when you turned it pulled up a cup this was mechanical. The last model I showed everyone was a water/windmill that when you turned the  mill cogs and wheels turned around inside and they made a stick on the end turn and it  was able to lift things off the ground this was kinetic energy. When I showed everyone these things I was trying to show them that you do not need batteries and electricity to make things work. After I had shown everyone the K-Nex models I moved on to water. There was a mini water wheel that when you poured water into the  funnel it made things spin and move.  I was trying to explain that we don’t need any electricity to make things move, spin, drive, and work. There was  only one thing that not everyone got to see but  every second group or so did. I got a bottle and made three holes in the side of it, covered the holes with tape, filled the bottle with water and hung from a tree when I took the tape of the water poured out from the sides and the bottle started to spin. Everyone thought that it was the wind making it spin but I told them that when the water came out it was like an energy that  turned the bottle, and everyone thought that it was a cool way to water plants. The energy funday was a huge success and everyone had fun.

 

Our Volcano

Chemical Energy

Mr. Dodd's 5th class were in charge of this station as we had done some experiments in our class before Energy Day.  The best fun was the volcano.  The group who made this were Naomi, Robyn, William, Patric and Jennifer and som of our friends helped too.

First we had to make the volcano.  We used plasticine to form a mountain around a bowl.  We got smaill stones and placed them around the base.  Mr. Dodd and some of us brought in the ingredients for our chemical volcanol.  These are the ingredients: two tsps of vineagar, two tsps of bread soda, two tsps of washing crystals, one lid of red dye and lots of lemon juice.

We had to tell each class who came to visit that these ingredients reacted against one another to cause the eruption.  The younger classes were fascinated.  Some people thought it was the best station!

We also showed them that Alka Seltzer reacts in water.  We had great fun on Energy Day
