Biodiesel

  • Key Stage 3
  • GCSE
  • Popular Activity
  • Topical

Type: Activity
Learning Strategy: Information retrieval
Topic: Fuels

UK fuel prices have reached all time highs. The EU and US hope biofuels will prevent fuel shortages and reduce greenhouse gas emissions. But others point out the downside of biofuels – including losing valuable food production land and biodiversity. In this activity, students learn about biodiesel production and make a game to show the pros and cons this newly-popular fuel.

Learning objectives

Students will learn:
• that biodiesel is a renewable fuel made from crops such as oilseed rape and palm oil
• about the benefits and drawbacks of producing and using biodiesel.

Running the activity

Display page 1, which introduces the dilemma. Mention that world biodiesel output quadrupled between 2000 – 2005. The EU says that, by 2010, 5.75% of transport fuels used should be renewable. This would need about 25% of Europe's arable land.

Then display page 2. Point out that there are many different biofuels, including fuels made from waste cooking oil. The diagram shows how just one biofuel – biodiesel – is made from palm oil (hot climates) or oilseed rape oil (cooler climates). Glycerol – the main by-product – has many uses, but is currently almost worthless owing to over-supply.

Ask small groups of students to follow the instructions on page 3 to make a snakes and ladders game of the pros and cons of biodiesel for younger students. They can use the pros and cons listed on page 4, or research further points (see websites below). You may wish to emphasise that there are no easy answers. Many western governments vigorously promote biofuels. But biofuel production is at the expense of

Really useful resource and easily differentiable. Got my Y9 class to justify to each other why they had assigned the cards to the "pro" or "con" pile if they disagreed. Makes a dry topic a bit more lively!

A fantastic resource which helps students use difficult langage in a fun setting using games and colour to entice them. It is certain to build confidence and improve student marks. Brilliant stuff!

I have 4 year 11 groups (lower ability). £ of the groups loved doing the activity and making the game, and 1 set hated it. Horses for courses? I thought it was easy to present and understand and on the whole a success. You can't please all the people all the time!

For my year 10 class - average but with some special needs (i.e. dyslexia) - this was an ideal lesson. It took about an hour with a good discussion on the pros and cons. I summarised these on the board for them. The snakes and ladders game was fun. I made it A3 and they made it in pairs, drawing on their own snakes and ladders. They just had time to play one game.

Used the snakes and ladders game with my 6th form class. Got them to research the pros and cons of using biodiesel instead of giving them the pre-printed cards. They then made the game and really enjoyed playing it!

Ran this with 3 of my year 10 classes at the end of the oils topic. Both lower sets enjoyed making the games and testing them but the higher ability found the game making beneath them. The information was suberb, really got them thinking and they wrote some fantastic essays on the what they thought - most finally deciding it wasn't worth the cost yet, and we should just use less fuel!

worked really well with my year 7 classes. i enlarged the snakes and ladders to A3 size. it was interesting listening to the students trying to decide what was a pro or con - some quite heated debates!

Used it with my Y10. Excellent introductory activity. It raises important issues that I'm not sure even all teachers have considered. i.e. plenty of biodeisel - where is the food grown? Not sure about the snakes and ladders.

This looks good to use (different bits for different years) for year 7 when they study energy from biomass; Year 10 when they study triglycerides and biofuels and even my 6th form Chemistry class might have a quick peek!

This should be really good and accessible for 11 year olds doing KS3 7I Energy Resources...BUT... I think your page layout designers missed a trick here, why aren't the consequences both good and bad available in the right size frames to cut and stick onto the snakes and ladders master grid? If there was a ready sized version of the different consequences it would be much easier for students to place their snakes and ladders with the appropriate comments. I know I can probably do the size changing myself - but when everything has been thought out carefully it seemed an obvious thing to do. We'll still be doing this next week and having fun.

Very creative and current, will be able to use when I start my lessons on energy. The linking of the pros and cons to snake and ladder game will definetely generate interest.
