Effects of Climate Change and Renewable Energy

In this video, Mr. N introduces a STEM project linked to the UNICEF Outright campaign, focusing on climate change and renewable energy. He demonstrates how to build a solar updraft tower, explaining its components and the science behind its operation. The video emphasizes the importance of renewable energy in combating climate change and encourages viewers to engage with STEM activities. Mr. N also provides contact information for further questions.
