01. EASTER QUIZ


Easter Quiz


Have you checked out the Parent’s Pack?

Because if you have, you'll already know our new Easter Quiz is a
walk in the park. This is because ALL the questions and answers come from the Parents Pack and all are related to the chocolate smeared, traffic jammed, fluffy chicked, bank holidayed time of year we all know and love.

The prizes are (
perhaps a little predictably) gorgeous posh chocs, so go on....treat yourself! Click here to test your wits against our quizmasters.

02. PLANET SCIENCE WHODUNIT?


Whodunit


It’s getting so close you can almost taste it. It’s VERY exciting and registrations are increasing ever faster so you better get in there quick! For all you teachers out there, trust us when we say that if you miss out and your class hears about it there’ll be no end of grief!

So, to re-cap, the Whodunit is a nationwide forensics investigation open to all schools teaching KS2 or KS3. Teachers need to register their class to receive an evidence kit. The clues in the evidence kit (once solved!) will tell your super-sleuth pupils which of our huge celebs (
James Beattie, Miss Dynamite, Zach Shaw, S Club, Busted and Blazin’ Squad) committed the dastardly deed. Results can then be sent to us and winners are picked for phenomenal prizes.

Phew! Got all that? Well then get registering

03. EXPLORE-AT-BRISTOL


At Bristol


This ever-evolving science centre is once again in tune with the nation’s curiosity and is putting on a fantastic Whodunit exhibition. Running from April to November, this exhibition features a hands-on investigation and participants are invited to visit the scene of the crime and use the clues to solve the crime.

And so to the crime - as is so often the case, it’s the innocents who suffer. In this case a baby rhino has gone missing and a security guard killed in the process. Who could do such a thing? Could it be an inside job? Do you have the observation skills and patience to find out?

Go to http://www.at-bristol.org.uk/explore/whodunit for more info and some great downloadable resources like activities to try at home and a forensics fact file.

05. I THINK THIS INK IS YOURS


Activity


This week’s activity of the week ties in nicely with the forensics theme because ink chromatography is a recognised investigative tool in solving crimes. Chromatography describes a range of physical methods used to separate and/or analyse complex mixtures. In the world of crime investigation this is most likely to apply to ink, either from pens or printers. This activity shows you how it’s possible to match an ink to its source.

YOU WILL NEED

Small plastic cups or glass jars

Blotting paper cut into 2.5cm x 10cm strips

Ruler

Pencil

Selection of felt-tip pens (water soluble if possible)

Water


INVESTIGATE.......... NOW!

1. Pour water into each of the cups so that it’s 1cm deep.

2. Measure 2cm from the end of the paper strips and mark with a faint pencil line.

3. Along this line mark three dots of different colour with the felt-tips (including a black or brown dot)

4. Put each strip of paper in a jar so that the coloured dots are at least 1cm above the water level.

5. Wait for 5 minutes and then remove the paper. The ink should have spread up the paper and separated into different colours.


BUT HOW DOES THIS SOLVE CRIME?

Each type of pen (or different colour in this case) has a slightly different make up. This is due to ink molecules of different shapes and sizes. The water going up the paper carries these molecules but then, at some point, drops them again. The varied size and weight of the molecules causes them to be dropped at different times up the paper. This creates a unique pattern for that particular ink which can then be compared against a sample, taken from a suspect’s house for example.
Ha! You’re impressed now – admit it!

06. RECOMMENDED WEBSITES OF THE WEEK

In at no.1 we have...

Kids Love A Mystery.com
http://www.kidsloveamystery.com


http://www.kidsloveamystery.com


One for the rugrat in your life. This site is aimed at kids but does also have a section for adults. The site is bright and colourful and gives kids a chance to use their grey matter to solve various mystery stories themselves. There’s a section of mysteries written by kids and also a ‘chiller’ section, which is pretty darn spooky! So go to http://www.kidsloveamystery.com and get sleuthing.

Cyber Forensics
http://www.cyber-forensics.ltd.uk


http://www.cyber-forensics.ltd.uk


No. 2 is a tad more serious and should really be reserved for those adults who find themselves absolutely fascinated by it all! Cyber Forensics is a site dedicated to a team who use computers in many different ways to catch out a criminal. So, if you want to know what happens when the papers say that someone’s hard drive has been seized, then look no further. The site is simple but effective and although the accounts are detailed, they are also easy to read and not too technical. Remember that every time you surf, they can find you......

07. SCIENCE BEHIND THE NEWS


Chocs


This week it’s less ‘Science Behind the News’ and more ‘Wait Till I Get my Hands on Whoever Dared Steal my Chocolate’. Oh yes, this is the way to go; the time has come for some serious investigation into what is obviously a very serious crime. If you have a chocolate thief in your house then now’s your chance to find out who it is and expose them to the household. Now for the punishment – how about making the culprit buy you a chocolate based treat every day for the next month!

Click here for a place that’s choc full of ideas to catch a cocoa obsessed pilferer!
