The Impact of society on environment

😈The impact of society on environment😈

I see that the environment here is very polluted, you may ask, why? The obvious answer is that people are using gasoline to power their cars which make acid rain - which is going on to another topic. As we use cars which are in use of this - carbon monoxide is being polluted into the sky - then, acid rain is being created and the impact of acid rain are; Damages buildings, polluted rivers and corrupted trees.

Image result for Nuclear powerWe all know what nuclear power is: it is the use of nuclear reactions that releases nuclear energy to generate heat. We see that heat may create global warming and the greenhouse effect. What global warming impact our daily lives (or animals' daily lives?) The thing here to talk about is that polar bears, penguins, and the arctic animals will suffer because of icebergs melting. BUT there is a theory that the cold parts of the land - ice wouldn't melt - it would be hard to melt and would stick together. Therefore - ice wouldn't be too easy to melt in the arctic parts. But as for humans - about 37 degrees celsius is about our "heat limit" so if there were to be a heatwave includes of global warming - we wouldn't be able to stand the heat of it.

Types of Clouds

☁ Types of clouds ☁

Cumulus clouds

Cumulus clouds are white puffy and fluffy clouds which usually means good weather. They look like pieces of floating cotton. Unlike Cirrus and Stratus which doesn't mean change in weather is coming or rainfall. They are 1000 meters high in the sky. 












Cirrus clouds


Cirrus clouds are thin, flat and featherlike clouds of ice crystals in the atmosphere which usually means a change in weather is coming. Unlike any other clouds, they are thin and flat, not fluffy like cumulus clouds. In addition, they are very wispy and they are 6000 meters high.

Stratus Clouds
Cirrus clouds are sheets of low, grey clouds that bring light snow, hail or rain. They look like a huge gray blanket that hangs low in the sky. Sometimes stratus clouds are on the ground or very near the ground, and then we call them fog.

My Highlights this year 

This year my highlights are that Physics about speed, time and velocity. These I am looking forward to getting better at it. Next year I am looking forward to many things, but I have no idea what it is now.

The effect of gravity on speed

Add Science Analysis
Procedure:
1. Put the ramp against the seat of a chair. Place the ramp and chair so that the ramp points towards the hallway. Have your teammate on the other end of the hallway.
2. Place the ball bearing at the top of the ramp.
3. Lift the ramp 20 cm and release the ball bearing.
4. Time how long it takes to travel in 5 meters.
5. See how far it will go.
6. Repeat the experiment three times for each height then do 40 cm, 60 cm and 80 cm.

Analysis (questions):
1. Describe how the balls roll off the ramp at each height - discuss the effect of bouncing other factors.

= The ball bearing rolled diagonally off the ramp and went very far (20 cm). The ball bearing rolled, also diagonally and not the furthest (40 cm). The ball bearing rolled, 3 times, almost vertically (60 cm).

2. Discuss what is the fastest speed reached and any factors that could improve this.

= The fastest speed reached 4.50 seconds and the way we can improve this, is having a smoother ramp which will make the ball roll faster in a rate, because there is less friction. But if we have a rough ramp the ball bearing will have more friction and will roll slower than the smoother ramp.

3.  Does the ball travel in a straight line, why or why not?

= The ball doesn't travel in a straight line which there are 2 factors, the first reason is that we placed it in where the ball rolls diagonally, the second reason is that there is wind which pushes the ball to the right or left.
