Click the above picture for information on how astronomers detect exoplanets.
Exoplanets are planets orbiting a star outside our solar system.

Click the picture to work out the speed of sound in water and glass.

How do the speeds compare to the speed of sound in air?

If you are investigating sound frequency while studying waves and have access to a BBC Microbit then have some fun coding to hear the octave of a frequency.
An octave means that the frequency is doubled. Pressing one button creates a sound of frequency 256 Hz and pressing the other double the frequency to 512 Hz.
Have some computing physics fun with the microbit.

The above code can be typed into the microbit python editor.

During the last few days before the Christmas holidays my students set about thinking about what a scientist would love to receive as a Christmas present.

There were some fantastic ideas.

The winner was Beth Gribben with her smashing science tie idea.
Congratulations Beth!

Runner ups were Kyle and Lewis.

What would a scientist like to find in his or her Christmas stocking on Christmas morning.
Well there were some excellent ideas.

I particularly liked Alana Jane`s time travel ring. Very Doctor Who.

The winning entry was from Brendan Tochel and Terri Letham`s cake maker machine.

Congratulations! Happy Christmas 2012 from Mr Mallon.
