Carbon Footprint

Lets Learn Energy Carbon Footprint

Carbon Footprint - How You Can Help

1) Walking or cycling to school is one of the best ways to get a bit of exercise and reduce your carbon footprint.

2) If this is not possible then taking public transport or sharing a lift with someone is good too.

3) Small steps make for big journeys. Recycling of packaging, clothes, food waste all make an amazing amount of difference.  Oh, and switch off the lights, and anything else you aren’t using 🙂 

The World of Energy programme is a 1-day primary school STEM workshop for children in Years 5 or 6.

‘Carbon Footprint’ is the tenth and final activity in the day where the whole class discusses what they have learned about energy, how we need to change, and what steps each of us can take to reduce our carbon footprint.

Appliance of Science

Lets Learn Energy Appliance of Science

Appliance of Science - What Uses the Most Electricity in Your Home

1) For a typical family home of 4 people the appliance that uses the most electricity is the electric cooker. That’s assuming it is on for 50 minutes each day cooking tasty meals for the family 🙂 

2) A kettle can use almost as much electricity as a shower, assuming you boil it 10 times a day, and assuming 4 people each take a 6-minute shower. 

3) Electric tumble dryers use a lot of energy too. Can you think of other ways to dry clothes? 

The World of Energy programme is a 1-day primary school STEM workshop for children in Years 5 or 6.

‘Appliance of Science’ is the ninth activity in the day where children in teams of 5 to 6 sort out the Let’s Learn Energy Appliance of Science cards in order of energy usage, ranking from highest to lowest.

Fuel Sources

Lets Learn Energy Fuel Sources

Fuel Sources

1) The world’s first coal fired power station opened in 1882 in Holborn Viaduct, London and was called the Edison Electric Light Station. This was the start of electricity generated by fossil fuels.

2) 75 years later in 1957, Britain connected Calder Hall, the first full production nuclear power station, to the National Grid providing electricity to millions of people.

3) In 2020 Britain got 25% of it’s electricity from wind farms, and is leading the way in building wind farms at sea, known as ‘offshore’. Wind, solar and hydro are replacing fossil fuels across the UK.

The World of Energy programme is a 1-day primary school STEM workshop for children in Years 5 or 6.

‘Fuel Sources’ is the eighth activity in the day where the whole class watches a short video with a climate change theme, and comments in their teams and to the whole class, applying the knowledge and ideas they have learned during the World of Energy workshop.

Turbines and Generating Electricity

Lets Learn Energy Wind Turbine

Turbines and Generating Electricity

1) Nearly all electricity that comes into your home has been generated by turbines. These are huge machines that use masses of copper wire spinning inside giant magnets to generate electricity.

2) These turbines are powered by fossil fuels such as oil, gas or coal. Another fuel source is nuclear, but best of all for the environment is to use renewable energy such as wind, solar and  hydro (water).

3) Lord Armstrong built the world’s first hydro-electric turbine for his house in Cragside Northumberland, in 1878. Now owned by the National Trust, the turbine is working again!

The World of Energy programme is a 1-day primary school STEM workshop for children in Years 5 or 6.

‘Turbines and Generating Electricity’ is the seventh activity in the day where the children in teams of 5 to 6 build a turbine from a model and generate electricity in model wind farms and hand held dynamos.

Magnets

Lets Learn Energy Magnetic Forces

Magnets

1) The core of the Earth is over 5,000 degrees celsius and is made up of iron. The iron is magnetic so the world is really a giant magnet and that’s why we have a North and South Pole. 

2) Explorers use magnets in compasses to point to the North Pole. Once you get a fix on the North, then you know which way is South, East and West. 

3) Chinese sailors were the earliest people to use a compass, around 1,000 years ago. However pigeons have been using the Earth’s magnetic field to navigate for millions of years!

The World of Energy programme is a 1-day primary school STEM workshop for children in Years 5 or 6.

‘Magnets’ is the sixth activity in the day where the children in teams of 5 to 6 experiment with magnetic force fields with iron filings suspended in oil and explore how electric currents effect a compass.

Batteries and Circuits

Lets Learn Energy Electric Circuit with Electrons

The History of Batteries and Circuits

1) In March 1800 Alessandro Volta from Genoa, Italy, made the first ever battery and demonstrated it to the Royal Society in London. 

2) Then in September 1820 Andre-Marie Ampere in Paris, France, showed a magnetic compass needle being moved by an electric current in a wire. His work in maths and science proved that electricity is a flow of ‘electrons’.

3) In honour of these 2 famous scientists we now measure the force of electricity in a circuit in ‘Volts’, and the amount of electrons flowing through that circuit as ‘Amps’. 

The World of Energy programme is a 1-day primary school STEM workshop for children in Years 5 or 6.

‘Batteries and Circuits’ is the fifth activity in the day where the children in teams of 5 to 6 create their own batteries and circuits from potatoes to voltaic piles made from zinc and copper. The concepts of Amps, Volts and Watts are introduced.

Calorie Gallery

Lets Learn Energy Calorie Gallery

Calorie Gallery - 3 Food Facts for Children

1) The NHS says that a child of 10-years old needs around 2,000 calories (kcal) a day to meet their energy needs. 

2) Our bodies burn energy from two different food types. The first is carbohydrates which is food made up of atoms of carbon and hydrogen. The second source is fat.

3) Sugars are processed in our gut for fast release energy. Fats are processed in our livers and provide longer term sources of energy. It’s important to have a balance.

The World of Energy programme is a 1-day primary school STEM workshop for children in Years 5 or 6.

‘Calorie Gallery’ is the fourth activity in the day where the children in teams of 5 to 6 explore the energy stored in different types of food, how much energy our bodies need each day, and other benefits such as vitamins, minerals and fibre for a balanced diet.

Atoms, Molecules and the Atmosphere

Lets Learn Energy Mount Everest Climate Change

Atoms, Molecules and the Atmosphere

1) Animals breathe oxygen in the atmosphere to live. The higher we go, the less oxygen there is, and the highest that people can live is 6,000 metres above sea level. Mount Everest is nearly 9,000 metres! 

2) Carbon Dioxide is a greenhouse gas that happens naturally when we breathe in Oxygen and breathe out Carbon Dioxide. We also make a lot of it by burning fossil fuels such as oil, gas and coal. 

3) Carbon Dioxide is also known as CO2. The ‘C’ stands for 1 atom of Carbon and the ‘O2‘ stands for 2 atoms of Oxygen. Humans are releasing too much CO2 into the atmosphere and causing climate change.

The World of Energy programme is a 1-day primary school STEM workshop for children in Years 5 or 6.

‘Atoms, Molecules and the Atmosphere’ is the third activity in the day where the children in teams of 5 to 6 experiment with building models of Hydrogen, Carbon and Oxygen atoms, and then putting these together to build molecules of CO2, H2O  and CH4 (Methane). They explore first hand the building blocks of life and the chemistry of climate change.

Particles and Waves

Particles and Waves - Light is Both!

1) Light is the fastest thing in the Universe. If you could run and swim at the speed of light, you could go around the Earth 7 1/2 times in a second! 

2) Light is energy and we cannot live without it. It makes plants grow, keeps us warm and lets us see things. Just think, oil and coal come from animals and plants that lived many millions of years ago.

3) White light is actually made up of lots of different colours. Blue light is a high energy short wavelength, good for solar panels. Red light is a lower energy long wavelength, which makes us feel warm.

The World of Energy programme is a 1-day primary school STEM workshop for children in Years 5 or 6.

‘Particles & Waves’ is the second activity in the day where children in teams of 5 to 6 carry out experiments into the nature of light and magnetic fields with prisms, torches, magnets and iron filings suspended in oil.

Sun and Earth Fun Facts

Lets Learn Energy Sun and Earth

Three Amazing Sun & Earth Facts

1) Temperatures inside the Sun can reach 15 million degrees Celsius. Now that’s HOT!

2) The light from the Sun takes over 8 minutes to reach us here on Earth. It travels 150 million kilometres!

3) The Sun is huge. It has over 99% of all the mass in our solar system. All the planets including Earth are less than 1 %!

The World of Energy programme is a 1-day primary school STEM workshop for children in Years 5 or 6.

‘Sun and Earth’ is the first activity in the day where the whole class takes part in a ‘parachute game’ to show how global warming works.
