KS3 (11-14)

Flipping forces

Next Tuesday is Pancake Day and to celebrate the flipping fantastic feast that it is, here is an idea that can be used to reinforce knowledge of force diagrams with KS2 or KS3 students.

Using the downloadable resource, students create their own diagrams to show the forces involved when flipping a pancake. More

The story

Did you know:  The hamster species P.roborovskii have been said to run the equivalent of four human marathons per night?

This interesting but apparently useless fact came to my attention via Guardian blogger Grrl Scientist.  The blog post went on to explain the ways that all this kinetic energy could be harnessed to power electrical devices and I thought that it might be a fun way of teaching about energy transfer.

Today sees the start of London zoo’s annual stock-take where the numbers of each species are counted. This task maybe a quick job for the keepers of the big cats or large reptiles but spare a thought for the invertebrate keepers, counting every butterfly could keep them occupied for up to 4 weeks.

Mega-crabs

 

This spooky video shows the giant red crab which have invaded Antarctic waters due to increased water temperatures: an example of how changes in non-living factors can alter the distribution of organisms.  This invasive species has the potential to destroy the delicately balanced food webs in this ecosystem.

Baby scientists

The story

I received an interesting letter in the post last week inviting my two year old daughter to take part in an international research study.

Today is World Health Day and the theme this year is antimicrobial resistance.
The World Health Organisation (WHO) is introducing a six-point policy package to combat the spread of antimicrobial resistance in order to slow down not only its effect on the health of people today but to safeguard the effectiveness of antibiotics in the future. More

Teaching ideas

For an interesting spin on a lesson on chemical reactions you could try making a ‘naked egg’, that is an egg without its shell. More

(or Happy New Year!)

The story

Thursday (3rd February) will be the start of the Chinese New Year.

On this night will be a full moon (good night for moon-watching) and the celebrations will end 15 days later when the lunar cycle is halfway through and there will be a new moon (not such a good night for moon-watching). More
