In this module is described how to experiment with old jeans. The module aims at about 14-year-old pupils. It has been written by pupils of the same age, after doing a project of three months 2 hour a week. The hat on the picture and this module is the result of that. Pupils in the third grade of my secondary school have classes in Physics, Chemistry and Biology. I was asked to give the more gifted children an extra 2 hours a week of "Science". For starters, I used a ready-made module from "new chemistry" [1] that involved a lot of experiments done on little pieces of jeans fabric. One of the differences I made was to cut the fabric in 8 relative large pieces that could be sewed into a hat after finishing all the experiments, thus involving technical skills as well. For chemistry, we whitened the jeans with bleach en made it "dirty" using KMnO4. Furthermore, we prepared some indigo. For physics we worked with pumice to get a stone washed effect. And for biology we used enzymes to get the fabric softer and whiter. After all this and having finished the hat, I had the pupils critically discuss the module, and let them pick the more interesting and fun experiments in it. They prepared a 45-minute lesson and gave this to others in the same class. After another critical review the entire class together prepared one lesson and gave this lesson to a different class in the same age group. They took remarks, did a last improvement and now proudly present the result on SOS!

This module consists of three parts. Students first make a short task on the computer about seeing depth and 3D pictures (perception). Second they use the camera to make some photographs. Third they convert the photographs they made into 3D pictures.

In this modules students investigate some properties of friction. They will find out more about the relations that Leonardo da Vinci recorded already centuries ago. In order to investigate friction at atomic level, the availability of an Atomic Force Microscope is recommendable.

In this module students are rowing on an indoor rower. During the rowing process they measure different conditions like the force by using only arms, only legs or both. The consumed calories are measured as well. In this module are elements of biology, physics and sports.

In this module students learn about the bungee-trampoline, a very spectacular machine. When you fall down after being launched, you discover free fall and zero gravity. In this module security aspects are investigated as well. How much G-force is working on you? What is the maximum height you can reach? What is the maximum speed you can reach? What’s the chance you fall on the ground? There is a test array for measuring the acceleration, force and height, and a computer model simulating the launch.

Every day you drink and eat. So everyday you consume a lot of foodstuffs. You need a lot of chemistry to prepare these foodstuffs. In this module you learn about fragrance and tasting agents, taste perception and digestion. In this way you get acquaintance with some elements of the foodstuffs technology. You will make your own soft drink and notice that familiar foodstuffs can taste completely different. Students also get informed about education and career prospects.
