The surface tension experiments:
For these experiments, we will need -
- A petri dish
- A pipette
- A measuring cup
- A peace cardboard
- Two coins ($2)
- Dishwashing liquid soup
- Hand soap
- Pepper (fine)
- Water
The first experiment was interesting. My dad told us to observe carefully, or we might miss the results.
I filled the measuring cup to the top. I had to be careful not to spill the water. My sister used the pipette to add water to the cup. She added one drop of water at a time. She stopped adding water, but my dad encouraged her to add more drops. So she added a lot more drops before my dad stopped her. What we saw next was amazing. The water was making a bubble over the top. It surprised me how many drops my sister added and it didn’t spill. I did the experiment too.
This is what we saw.

Very interesting Edmon. Did it take a lot of time to prepare?
ReplyDeleteno, it didn't and it was a lot of fun.
DeleteThank you for sharing your science experiments on your blog. What a great idea to take a video of your experiment. I am also surprised of the results. Fantastic learning Edmon and whanau!
