No Effect 😱

Something that I think should be affected by another thing is a glue stick. We use glue to stick things together... But!! Why doesn't the glue stick into the inside of the bottle? It doesn't  stick inside the bottle because the inside of the bottle has a speacial material that doesn't get sticky with the glue. 😌🤓👏🏼🙌🏼

Standing Waves 🌊

Today we did a lab called " Standing Wave Lab". In this lab we stretched out a spring and looked for the frequency, the wavelength, and it's speed. After this lab I learned that waves with different shapes have different speeds. But also tht the waves amplitude doesn't affect the waves speed. 

Electricity Generator

I'm really interested in the Hydro Electric Power generator. I chose this generator because I find it I interesting how water makes a turbine turn to make us electricity. This generator works by a dam blocking a body of water until the fills up then it releases the water which makes a turbine turn.  Its one of the better forms of electricity generation because the air is goin to be clean. One thing that is bad bout this form of electricity is finding a location to install a dam. This is a pro elm because you can't put a dam where there is a river near a city. Cuz when the dam fills the city can get flooded. But really, anywhere that there is a big body of water you can install a dam not next to a city. 😊🌊
