We used a hairdryer to make the propeller turn, which lit up the LED light when it was connected by crocodile wires. The kinetic energy of moving air (wind) turned into electrical energy.]]> 2022-03-13 14:08:23 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2092352077 larisalawson https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2092369502 We worked in groups to build a paper tower turbine design. Through research, we discovered that engineers have to take many different factors into account in order to improve the efficiency of wind turbines.
* Choosing the right materials to build with
* Designing the shape of the blades
* Choosing the most suitable location
* Making the blades longer
* Making the turbines taller
We decided that a wind turbine would suitably feature in our model school. We will place it in an open area.]]> 2022-03-13 14:30:35 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2092369502 larisalawson https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2092377827 We measured the wind speed in different locations around our school grounds, and at different times of the day, using an anemometer.

The wind speed in Hamilton today is 4.4 metres per second (MPS). Our wind speed results reached 3.8MPS on a mild day. We think our school would be a suitable location for a wind turbine.]]> 2022-03-13 14:41:31 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2092377827 larisalawson https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086089 We made a floating turbine, experimenting with different materials to use as weights for our floats. We moved the float up and down the wooden dowel until we had a tall and stable turbine.]]> 2022-05-30 21:45:44 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086089 larisalawson https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086246 We did an experiment to show how we can make power from light. When we held the solar panel to natural light, the LED lit up clearly, when connected by crocodile wires.]]> 2022-05-30 21:45:59 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086246 larisalawson https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086358 Visit from Gillian Reilly
Primary Science and Sustainability Development Officer
South Lanarkshire Council

Today we explored Micro:Bits and Gillian told us about the final project challenge which is to build a more sustainable model of our school (in the future), showing our learning.]]> 2022-05-30 21:46:11 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086358 larisalawson https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086444 2022-05-30 21:46:23 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086444 larisalawson https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086566 We ordered statements, with a variety of benefits of trees, from most to least important. We learned that there was no right answer and that trees have a lot of benefits. ]]> 2022-05-30 21:46:37 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086566 larisalawson https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086639 We made a battery using a mixture of vinegar and salt which acted as the electrolyte. We soaked 6 card discs in the mixture then made a tower of 2p coin, washer, card disc (x4) This tower acted as a battery and lit our LED light, when connected. We tested the battery voltage and it reached 2.7V.]]> 2022-05-30 21:46:46 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086639 larisalawson https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086763 We began building our model school of the future. ]]> 2022-05-30 21:46:59 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086763 larisalawson https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086865 We completed our model of OLSA as a sustainable school of the future and will present our project to our friends at assembly. ]]> 2022-05-30 21:47:12 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2205086865 https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2219418469 2022-06-13 11:21:40 UTC https://padlet.com/larisalawson/7171zloxanwzg2ur/wish/2219418469
