Youth groups offer many advantages to young people.

These include Guides and Scouts, Brownies and Cubs, who need to work towards activities and experiences that show they are becoming better human beings. These activities are shown through the displaying and working towards the award of a badge.

We have experience delivering a number of badges, including the Science and the Photography badges.

Guides in Mossley

We will help you plan and undertake experiments or research to show you understand the science behind the activity.

Identification for Brownies Science Investigator

  • Find out what makes me, me. – DNA and the chemical you
  • Make a pinhole camera and use it to look at another Brownie
  • Compare your fingerprints with the rest of your unit or a group of friends – can you find your own? Develop fingerprints on multiple surfaces and compare against your own
  • How clean am I?  Find out about how bacteria are spread. Understand the importance of washing your hands through the transfer of evidence in forensic science

We combine this with our scientist, or forensic professional who will visit and  talk to you about their work.

Science Badge for Girl Guides

Complete all of the sections.

  • Plan and undertake experiments or research in two of the following areas. Show you understand the science behind what you have done.
    1. Crime Scene Investigation – find out what happens when a crime is being investigated. Take part in the investigation
    2. We combine this with our scientist, or forensic professional who will visit and  talk to you about their work.
  • Find out more about two famous scientists which is combined into our discussions and hands on activities about fingerprints and DNA


Carry out six activities. Cubs should choose at least one from each of these sections.

For each one, explain or show to a leader what you did and what you found out.

Section 1: reactions

  • Show how vinegar reacts with different items and explain what happens. The different items could be steel wool, sodium bicarbonate or old dirty coins.
  • Find out what happens when you add salt to water.
  • Compare the density of water to the density of other liquids. Show how these liquids react to each other.
  • Make a pH indicator solution. Use it to test the acidity or alkalinity of other liquids.
  • Grow crystals.

Section 2: interacting with energy

  • Create a basic electrical circuit which includes a switch. Show how it could be used to control a lightbulb powered by a battery.
  • Make an air powered balloon rocket or a water rocket. Investigate ways of improving how far it can travel.
  • Make a simple compass. Show the effects of metallic and magnetic materials upon it.
  • Use marshmallows  and spaghetti to build the strongest tower you can. Explain how you have improved your design.
  • Find a way to show that hot air rises.

Section 3: living things

  • Set up a wormery or ant colony. Record what happens over three or four weeks
  • Investigate what happens to your pulse rate before, during and after
  • Grow cress, beans, peas or a similar plant. Investigate what happens when the plant has no access to light. What happens when it has light,
    but no water?
  • Find a way to show that plants take water up through their stems.
  • Make some yoghurt and find out how living organisms are involved in
    the process.
  • Discover what a fingerprint is, where it comes from and how it can be used to identify you.

It’s fine if you’d like to do a different experiment which fits under one of the categories. Just get agreement from your leader.


Discover how to investigate a crime scene.

  • Pick an item of evidence and research it to discuss or present to your leaders.
    • Fibres
    • Light
    • Fingerprints
    • DNA
    • Bite Marks
    • Hair
    • Tire marks/shoe marks
    • Handwriting/ink
  • Take part in the processing of a crime scene as part of a team and solve the crime
  • We combine this with our scientist, or forensic professional who will visit and talk to you about their work.

Complete Forensics has the capacity and scope to deliver all the above activities. This is because Forensic means in the public forum, so forensic science is using science in public, which we do to the courts delivering facts scientifically proven.

The cost of this activity is per troop, not per person. Number limits do apply so please contact us first.
