Science Week: Day 2: How do Batteries Produce Electrical Energy?

Our fun facts about using batteries to produce electrical energy:

When did scientists first begin to harness, store and generate electrical energy?

Efforts began in the 18^th century. Benjamin Franklin, Luigi Galvani, Alessandro Volta, Michael Faraday, Thomas Edison, Nikola Tesla and Albert Einstein helped us too understand how electricity worked.

How is the electrical energy produced in the battery?

A chemical reaction occurs between the two metals that are separated by paper soaked in vinegar. When this happens an electron is generated and is spit out into the wire. When this is connected in a loop current flows and electricity is produced.

What is the difference between a primary cell and secondary cell battery?

The major difference between a primary cell and the secondary cell is that primary cells are the ones that cannot be charged but secondary cells are the ones that are rechargeable.

What are the applications of batteries in everyday life?

Batteries are used to power things like remote controls, torch, wall clock, flashlight, hearing aids, weight scales, etc. Rechargeable batteries are also used in various devices like digital cameras, mobile phones, batteries of vehicles, video game devices, remote control cars, home maintenance tools, and many more.

What are the environmental aspects of the use of batteries?

As batteries corrode, their chemicals soak into soil and contaminate groundwater and surface water. Our ecosystems, which contain thousands of aquatic plants and animals, are compromised when filled with battery chemicals. This means that when we drink from tap water faucets, we could be ingesting dangerous metals.

Science Week

During Science Week in Fourth Class, the children engaged in exciting activities centered around the theme of Regeneration. They delved into the topic of Energy, exploring renewable energy sources and their role in protecting our ozone layer.

Christmas Wreaths

Fourth Class got into the festive spirit this week by creating beautiful Christmas wreaths to decorate their homes. Using oasis as a base, they carefully arranged holly, ivy, and greenery, finishing with a dusting of snow spray for a magical touch. The children showed fantastic creativity and focus, designing stunning centrepieces to brighten up their kitchen tables over the holidays. Well done to everyone for their hard work and festive flair!

Winter Birch Trees

We had great fun using paint, masking tape and glitter to create our masterpieces! We also learned some new facts about Birch Trees. Take a look! Ten Facts about Birch Trees Birch trees are found in the northern half of the world. They grow in areas with cool to cold weather. The trees called birches have long been known for their beautiful bark. N ative Americans used birch bark to make canoes, tepees, and moccasins. Today people use birch wood to make furniture, flooring, and plywood. The bark of all birches is characteristically marked with long, horizontal lenticels, and often separates into thin, papery plates, especially upon the paper birch. Birch trees have simple leaves with toothed edges called margins. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. It is an elegant deciduous tree, with arching branches that droop gracefully towards the ground. It usually grows to about 15-20 metres high. The catkin...
