We caught up with the Scrub up on Science Challenge judges to find out their top tips to help you create a winning entry for this fantastic competition.

About the challenge

The Scrub up on Science Challenge is a STEM competition for 11 to 16 year olds developed by the Society of Cosmetic Scientists. Students can learn about real-world cosmetic science, and mix creativity and a knowledge of chemistry to create a quality bath bomb or bubble bath – aiming for the biggest bubbles, the longest-lasting fizz or the most striking scent.

Top tips from the judges

Dr Barbara Brockway, one of the competition judges and scientist with a wealth of industry experience, shared with us her 5 top tips to impress the judging panel and be in with a chance to win:

  1. Understand the chemistry behind your product. We want you to show us your chemical knowledge, and the scientific explanation for how your bath bomb or bubble  bath works.
  2. Make a hypothesis. The competition is all about scientific experiment – so make sure you create a hypothesis, then prove or disprove it.
  3. Inspire and engage with your video or Powerpoint. We want you to persuade us as to what makes your product stand out. Put work into your video or Powerpoint submission – presentation is key!
  4. Tailor your product to the customer. Decide on the intended audience for your product, and then explain how your product will appeal to them.
  5. Show your enthusiasm. Our competition is all about developing an interest in STEM and the Science behind cosmetics – so let your passion for Science shine through!
