Planting trees

Our new ELI today is 'Let's plant some trees; investigating the importance of trees to our planet'.

In this activity afforestation and reforestation are considered and all the ways that trees are important to our planet are discussed.

Other activities related to reaching the 'net zero' emissions target can be found on our website.
 

Party time for volcanoes!

This is a good time of year to try 'Party time for volcanoes! How much force does it take to set off a party popper “volcano"?'

This activity measures the force required to burst a party popper; it provides a quantifiable way of measuring a gradually increasing stress, akin to the build up of pressure beneath a volcano, or the increases in stress as rock masses begin to move relative to each other. The variable results obtained relate to the prediction of volcanic eruptions or earthquakes - and it's great fun!

Many more Earthlearningideas about volcanic eruptions and earthquakes can be found on our website.

Potential source of energy from flooded, old coal mines

Our new ELI today and another in our 'net zero' emissions series is, 'A new use for old coal mines; a potential source of energy from beneath our feet'.

This activity investigates how geothermal heat in flooded coal mines might be used to heat our homes and workplaces.

Volcanic eruptions - which classroom eruption is best?

Following the eruption of Mt Semeru on Java in Indonesia, the ELI today is 'Best classroom eruption? Which type of classroom eruption best shows how volcanoes erupt?

 

 

This Earthlearningidea evaluates different types of classroom eruptions to gauge which best shows how eruptions are triggered.

Many activities about volcanic eruptions can be found by using the search engine or alphabetical index on our website.

Small-scale hydroelectric power schemes

 The new ELI today and the next in our 'net zero' series is 'Small-scale hydroelectric power schemes; investigating opportunities for micro-hydro'.

 

This activity is an introduction to electricity generation by micro-hydro schemes and explores the benefits of cheap, small-scale hydroelectric installations.

Many more activities about renewable energy supplies can be found on our website.

Earthlearningidea videos

Did you know that, as well as all the teaching videos, ELI also has many general videos from various sources; four are in Catalan, three have a Portuguese introduction and one is narrated in Norwegian.

Landfill gas

The new ELI today is the next is our 'net zero' emissions series, 'Energy from buried waste: Landfill gas'.

It is vital that modern technologies are developed not only to manage waste but also to ensure that minimal harmful by-products are allowed to pollute the air or the ground. We must re-cycle as much as possible and mitigate the effects of non recyclable material. This ELI is a case study of good practice by an industrial firm to try to reduce its use of fossil fuels and to assist the local community in reducing its carbon footprint
