Abstract
SLIME is popular amongst kids and adults because of its texture and the possibilities to manipulate it in a playful way providing a unique sensory experience. There are plenty of recipes for making homemade slime but not all them are equally good, since some contain borax that can cause skin, eye or respiratory irritation and other health problems.
This activity challenges students to investigate the possible ingredients and the best procedure to make a safe slime. They will have to meet the challenge in groups, discussing alternative strategies, describing observations and searching for explanations
