Detective science day

Do you want to plan a whole-school science day? We have a mystery for the whole school to solve! The children will practise their observational skills and learn about the job of a forensic scientist.

Before the pupils come in, set up a crime scene. The crime is that someone has eaten the last cookie from the staffroom. You will need to decide which member of staff is the culprit and plant the evidence accordingly. There will be lots of clues; a handwritten note, some footprints, a glass with clear fingerprints on. The crime scene will need to be in an area that the whole school can visit and access during the day. You could set it up in the hall and have a whole-school assembly to explain the crime. The evidence could then be put on a crime scene board and each year group given one piece of the evidence to investigate, just like forensic scientists.

Check out our detective science issue!

F2

Part of crime detection is looking carefully for clues. Pupils could play lots of games in which they must spot the odd one out; for example, fill two trays with objects so they look identical, but with something missing from one tray – can they spot it?!

Year 1  

They will investigate footprints. Pupils will first compare their shoeprints to find out if they are the same. They could then ask all the members of staff for their shoeprints. Can they match any of them to the ones at the crime scene?

Years 2 and 3 

They will be taking fingerprints. Are all of our fingerprints the same? Discuss how they are unique. Follow these instructions to take fingerprints.

Year 3 pupils could take the fingerprints of all the staff members and see if they can match any of them to the ones at the crime scene.

Years 4 and 5

Can they match a pen to the note from the crime scene? Give pupils a selection of pens, each one belonging to a different member of staff. (You will need to use water-soluble pens for the test to work.) In the crime scene, make sure there are some pieces of kitchen roll with ink spots on them, which match the note left by the cookie-stealing culprit.

Pupils will try out chromatography. You will demonstrate how to do it and then they will test the staff members’ pens, making sure they work methodically to ensure it is a fair test. Do any of the pens match the clue in the crime scene?

Year 6

They should already know that humans are all different and that we carry characteristics from our parents. Explain that we all have DNA – in fact, all living things have DNA – and that it can be used to help to solve crimes. Scientists can extract DNA from all sorts of evidence, including hairs, fibres, etc. Explain that it would require specialist equipment to do this, but we can extract a DNA strand from a strawberry.

Download our lesson pack here for the full instructions:

At the end of the day, bring the whole school back together. Ask each class if they think they know who took the last cookie. Work through the crime scene board and see if they all came up with the same member of staff. Did they manage to solve the crime?

As part of the day, pupils might like to read about some real-life detectives or some animal thieves. Check out these reading comprehensions available to download from our website:

Fly High Friday – FREE ideas for Science Week!

Science Week Day, March 2021

British Science Week (5th-14th March 2021) was always first in my calendar as a Primary Science Co-ordinator and I usually started with very grand ideas! Whilst a whole week of science is brilliant, this year it might be more realistic to consider just planning one day – it will be just as exciting, but manageable both in school and for any pupils isolating at home. Here are some FREE ideas and resources for creating a super exciting Fly High Friday!

Did you know that Whizz Pop Bang magazine also creates curriculum-linked science resources for primary schools? Scroll to the bottom to find a brilliant offer that’s running throughout March 2021!

Here’s everything you need to make planning your science day as simple as possible:

  • A whole-school challenge with suggestions for each year group
  • Science lesson plan with curriculum links
  • Downloadable, printable resources
  • FREE PowerPoint presentations to help teachers run the day

Theme – Flight, linking with the curriculum topic of Forces with a comparative/fair testing enquiry and for EYFS the characteristics of learning.

Challenge the whole school to work together on a flight investigation!
The mission: who can make paper fly the farthest?
Keep reading to find activities and resources for each year group…

We all love to make a paper aeroplane but is that the only way to make paper fly? Here are some different ways:

Make a paper air-powered rocket

Printable stunt planes that fly in a circle!

Make flying paper straws

How to make these suit all year groups:

For all these ideas you will only need paper, straws, sticky tape, glue and sticky tack – and some space, preferably outdoors! Each year group could have a go at making these different paper flying machines.

EYFS – Allow the children the time to explore how they can make paper fly. The teacher could demonstrate the air-powered rocket, then the children could make either the stunt planes or the straw planes. The children will choose the one they think will fly the farthest, try it and then the class teacher should record the result.

KS1 – Again allow the children the time to explore how they can make paper fly. Then the children should make each of the flying devices and choose the one they think flies the best, then test it. The teacher can collate all the results as a class.  

Years 3 and 4 – children can choose their favourite design and then make adaptions to see if they can make it fly farther and record their results.

Years 5 and 6 – children can test each design and then make their own flying machines. They should throw their final design five times and calculate the mean result. This will be their final result.

We also have a reading comprehension about historical scientists the Wright Brothers, the team behind the world’s first powered flight.

The Wright brother Reading comprehension

At the end of the day all classes should share their results. This might be by email or you could hold a virtual assembly! Don’t forget to ask for photographs so you can make a display or share them on your school’s social media platforms. We would love to see what you’ve been doing so please tag us @whizzpopbangmag

“Using Whizz Pop Bang school resources has enabled investigations to be an integral part of my science planning. I now have investigations and experiments throughout my planning rather than just at the end. The lessons are easy to resource and the pack has everything I need to teach the lesson so it saves me time as well!”
Louise Hampson, Year 3 teacher
