Meteor hits London!

http://youtu.be/67JiLl1NM7U

OK – so this did not really happen. It”s a PR stunt to mark the start of science month on the TV channel, Eden. However, the video does talk about what could happen if a real meteor of this size hit London, and it would be a lot more devastating than one crushed taxi. More

Science in the News-letter #19

This week’s newsletter contains two stories that highlight man’s effects on other species on Earth. Lonesome George – the last Pinta giant tortoise died last week and computer models have been used to predict a major decline in the population of emperor penguins due to climate change.

 

The value of water

The story

As human population grows and pollution levels rise, our demand for clean water increases but its supply dwindles. How long will it be before our planet cannot provide its population with enough clean water to survive?
Some would say that this is already happening..

Japanese design company, Takram, was asked to design a water bottle that could be used to used to ensure that we could get enough daily water to survive if the worst case scenario become reality. But they went one step further and designed a set of cyborg organs, the Hydrolemic System, that could be used to reduce water loss from the body in order to keep intake down to a minimum.

The video shows how they would work.

Did you know: Everest is not the highest point on Earth? Find out why in this week’s newsletter along with lots of other interesting stories and facts.

I have changed the shortened URLs as it came to my attention that very often these are blocked when trying to access them from school. I hope the new-style ones work – please let me know if not!

 

LED: Light Emitting (whilst) Dancing

This video shows an amazing new type of light show at a recent Coldplay concert. Each audience member is given a wristband containing LEDs. These are controlled centrally so they light up in time to the music – a trully interactive experience.
Each wristband has a receiver, which allows data to be sent via radiowaves from a transmitter attached to a computer.
Showing the video would make an engaging start to a lesson on the uses of radiowaves.

Science in the News-letter #17

Lots of lovely space news this week with the discovery of another two Jovian moons plus the news that Voyager 1 has almost left the Solar System. Also, the building of the largest telescope in the world has been given the go ahead in the hope that we will be able to look deeper into space and time. Some exciting stories to inspire budding astronomers!

 

Science in the News-letters

A double post this week as both the latest Newsletter for KS4/5 and June’s Junior Newsletter are ready for download.

June Junior newsletter

Stories included look at food webs, infectious diseases and forces. As always there is a question suitable for KS2 and one to extend KS2 students or for KS3. Teacher notes are included.

 Science in the News-letter #16

This edition features questions based on the transit of Venus, prenatal genetic tests, GM apples that never go brown and a couple of chemistry stories on two new elements and an Olympic themed allotrope of carbon.

Edible diamonds

The story

I have been busy in the kitchen for the past few weeks trying to perfect the technique for growing edible sugar ‘diamonds’ and I think I’ve just about cracked it. This is so I can share an activity with you for your KS2 or KS3 science classes that is related to the Queen’s diamond jubilee – the things I do in the name of science!

This is a gem of an activity (sorry!) that you could do as a fun lesson on the last day before the half-term break or you could give it to your students to complete as a homework over the holidays. All the equipment needed for the experiment you can easily find at home. More

Super stunt science

This video from last week shows stuntman Gary Connery falling 2400 feet without a parachute and surviving to tell the tale. This would be a great story in a lesson on forces with any age student.

The students could:

  • Name the forces acting on him as he fell.
  • Calculate his average speed by using time from the video clip and using the speed equation (2400 feet = 731.52 m). As he fell for around 19 seconds this makes it an incredible 38.5 m/s (86 mph)!
  • Draw force diagrams for when he just left the aeroplane (unbalanced forces), when he was at terminal velocity (balanced forces) and when he had just hit the boxes (unbalanced).
  • Explain why his suit helped him survive the fall. More able students can link forces, particles and energy in this explanation.
  • Calculate his potential energy when he was in the plane (mgh). Gary is approximately 84 kg.
  • Sketch a velocity/time graph for the fall.

If you have any other ideas – please leave a comment and share!

La mini-roulette est une version très allégée du jeu de roulette classique et peut être un bon moyen pour commencer.co.uk/wp-content/uploads/2012/05/science-in-the-news.png”>It was an important week for the future of space flight as the first commercial space-craft sent to the ISS docked last Friday – is this the first step in manned commercial space flights? This, and four other interesting stories are highlighted in this week”s newsletter. Each story is linked to an area of the KS4/KS5 curriculum and can be used as a display poster, homework activity or just to give you some ideas on how you can use some topical stories in your lessons next week.
