> first layer: gravel | |||
> second layer: soil | |||
> third layer: taller plants (place them et the back), smaller plants (placed at the front) | |||
> next step: place moss, nice looking stones and pieces of tree trunks | |||
> last step: place tiny insects that are good for the little eco-system: for example snails and spring tails | |||
- by using different types of soil and plants I can experiment with divers terrariums and observe how they will turn out | - by using different types of soil and plants I can experiment with divers terrariums and observe how they will turn out | ||

> first we made Agar Agar by mixing 1.78grams of Agar Agar with hot water in a glass container, through shaking it, it became more solid over time. | |||
> we pured the mixture into a plastic straw, let it cool off and then cut the straw into sections to get long solid agar agar pieces. | |||
> next we prepared the petri dish for the experiment: placing the solid agar agar in the middle. Using hot glue and pouring diagonal line over agar agar piece to create a wall | |||
> now the petri dish has two seperate sides with an agar agar bridge in the middle | |||
> we then glued a cable on each side that sticks out of the petri dish | |||
> then we placed assembled mudd on one side of petri dish over the glued cable and water on the other | |||
> we made sure it contracts the agar agar bridge in the middle | |||
> the microbial fuel cell is created | |||
> last step to confirm the electricity flow, we connected claw clips from a digital multimeter to the cables that stick out the petri dish and observed the electricity outcome | |||
> it ranged from 0.012 - 0.300 volt | |||
