Where: Francke Foundations, Franckeplatz 1
When: 29 April 14:00-17:00
GYA members meet school children (3-4 grade)
Expedition Mundus, an inquiry-based science education game, was created to allow young kids to experience how it is to be a scientist. The children will think like scientists by formulating their own hypotheses, and act like scientists by testing their hypotheses and looking at previous observations. To play this game, kids will be grouped into twos or threes and will be provided with question cards. Kids work collaboratively by exploring various posters to find answers to their questions. These posters contain information gathered by scientists who previously visited the Planet Mundian. The team then heads back to the game facilitator to check if their answers are correct. The kids with the most number of correct answers win the game.
The Science of Light
We need energy to keep us warm in winter, to turn on the lights in the dark, or to boil water. Currently, most of the energy comes from coal, oil or gas, which we burn. However, large amounts of CO2, which we all know from sparkling water, are produced. Unfortunately, CO2 is a problem because it enhances the greenhouse effect, which causes the planner to heat up a bit more each year. On the other hand, the sun contains almost inexhaustible amounts of energy. A solar cell can tap these amounts of energy by directly converting sunlight into electricity, producing whole without CO2. Unfortunately, currently only little energy is gained from sunlight. This is also because it is technically not easy to produce well-functioning solar cells.
This activity will demonstrate interactively with children the so-called dye solar cell, which consists of common household materials. It uses dyes, such as those found in berries. Light arrives at the dye and can then be converted into electricity. The quickly produced electricity can then subsequently operate a device. However, a lot of craftsmanship is required because the solar cell consists of many different layers that perform many different tasks. It’s like a puzzle or building something with Legos. For it to work, all the parts must mesh and fit.
In this activity, children will be able to produce a (hopefully) working solar cell that uses berry juice and then generates electricity directly from light.
