Innovation Day 2021

Hi, everyone! Welcome to our blog about Solar energy. The sun has produced energy for billions of years! This means that people have been using solar energy to cook food, stay warm, and dry clothes for hundreds of years. Solar cells convert sunlight into electricity. Photovoltaic cells are another name for solar cells. The terms “picture” and “voltaic” are Latin for “light” and “electricity,” respectively. We chose to do solar energy for our project because it is eco-friendly and once you buy the solar panels the rest is all free! We are excited to show you our model for an eco-friendly park!

COVID-19 has made a huge impact on our lives. We can’t go to many places such as:

  • If your family member is in the hospital, you can’t go and visit them.
  • Social Areas
  • Restaurants
  • Amusement park
  • Work Areas

There is a good side to COVID though, for example:

  • Your parents have to work from home so you get to spend more time with them.
  • People use cars less so there’s not as much gas pollution in the world as there were before.
  • Not that many crimes are going on.
  • Not many trees are being cut down because the animals in forests can have the virus. 

Our idea was to build an energy-efficient playground with a zipline, a swing set, a play structure with a ladder and a slide. Solar panels will be found around the park in certain different areas, we are using solar panels to power lamp posts around the park and the swing set will move on its own so the parents will not have to push their children. Even though solar panels cost money, it is fine because sunlight is free! The park can still maintain the fun and entertaining aesthetic of a park. The zipline is also very fast which is very fun to go on.

Science Experiment

On January 20th, 2021 we had this scientist in the school experiment. Our job was to find out what this mystery powder was made of. First, we had to dip flour into water, and the water became foggy. Then we had to dip Epsom salt into water, the water was clear and the salt dissolved. Then we had to dip baking soda into water and it also turned out foggy. The next step was to dip a Q-tip into water then draw a line with that Q-tip on black construction paper. Then we did the same thing with flour and baking soda. The water line took a long time to dry but the Epsom salt dried really quickly and the baking soda also dried pretty quickly too. Our next step was to dip Epsom salt in water and see how many spoons it took to not dissolve. It took me four spoons until it did not dissolve. Then we had to dip cabbage and vitamin c and baking soda into the water and the water inflated with bubbles. In the end, we found out that the mystery powder was baking soda and flour.
