FINAL CONCLUSION: THE LAST DAY

We learn about recicling the differents products and reduce our ecologycal footprint. We like this subject because is very interesting and easy. We learn to do soap from the oil. We make experiments and we creat charts in the results and we write coclusions about this. We learn new vocabulary. We use new scientific instruments. We discovered the impact of polluting products and we spend a good time.

Recycling oil:

To recycle oil we dicided to make soap. We took 20 ml of oil and we filtered it. Then we put 4 g of hidroxium of sodium in a erlenmeyer with destilled water. Then we mixted the filtred oil with powder soap, hand soap and flour. This mixture we atted to the destilled water and hidroxium of sodium. Finally we waited for a week.
