Chemistry Day
Germs Germs Go Away and Fizzing Eye Balls Experiment!!!
For Healthy living and Chemistry Day we have been discussing what germs are, where they are found, how germs spread and how we can get rid of them. We also made our very own vanilla soap bars!!!
The children collected germs samples from around the school eg from the toilet , door handle, floor and from their own washed hands and dirty hands. They carefully placed their samples in agar-filled Petri dishes. The children made predictions as to which sample will have the most bacteria/germs. We will keep the Petri dishes under observation for a few days and see if our predictions match our final results!!!
To show how germs spread, the children rubbed hand lotion together with the glitter ( pretend germs) on their hands. In this way, they could visually see how germs spread. We used paper to wipe off the germs but it didn't work so well. The children then washed their hands with soap and water and all the ‘germs’ was washed away.
To show that germs don't like soap and water, we sprinkled some pepper(germs) into the water. The children dipped their soap-covered finger into the middle of the peppered water. They were amazed to see the soap repelled away the pepper( germs).
Finally we made our very own vanilla fragranced soap bars with cornstarch ,oil,liquid soap, vanilla essence and food coloring!!!
They also loved the fizzing eyeball experiment with vinegar and baking soda!!!
Purpose:
To learn about Germs and understand importance of maintaining their own health and well being.
To build their curiosity and be able to investigate, observe, make predictions and compare results
To be able to measure dry and liquid quantities
Connection to Lpfö:
Develop their understanding of science, relationships to nature, and also simple Chemical processes.
Develop their ability to distinguish , explore, document, put questions about and talk about science.
