Answer question for lab




You can use the density to define material by using water displacement method to calculate density by finding mass then divide by the volume of the water

I think the density and the color are both useful because we can identify the mineral by seeing the color and looking for the same of it and the density can be used to know the mineral that heavy or light then you can compare it.

Impact of environment on society

    The Environment pollution increase of temperature that can cause the global warming and effect such as melting ice and snow early, the habitat of the polar bear will be destroyed, heavy rain to increase flooding. 
      It may lead to having an acid rain that harms the forest such as can't grow a tree, the river be acid, etc... 
     The oil spills kill marine like whales dolphins and sea animal and cause damage their food supply and it can cause to have more disease and it will spread out in society

Type of cloud 

I think this cloud is cirrus because it thin like a feather 


 This is the cumulonimbus cloud because it is dark and it fat and fluffy 
This is the cumulus the sunny fat fluffy cloud that mean it good weather



This is the stratus because it is like a sheet of low gray cloud that will be bring the light rain and snow 








My plan

My highlights of this year are I join in World scholar and I can debate or write the essay longer and have more information.In World scholar we learn history, art, science, etc... I have fun about the new topic. I have my grade piano test so I have to work harder and practice more I get a high score. In this year most of sports I love to play tennis and table tennis it very fun and next year I will try to play other. My plan to do next year is to have a test next level of the piano and I will try to play drum and other instruments. I think if I have time I will go and practice football or other sports so I will get stronger and healthier.

ball bearing lab


1.         Describe how the ball rolls off the ramp at each height—discuss the effect of bouncing             or other factors.
           
            The more heigh that we roll the higher you get bouncing but less farther you get.

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

            The fastest speed is 1.6 cm./sec. I think the factors that will improve this is  the heigh of ruler and the ball type that it small or big or soft or heavy

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

             The ball not go straight line I think because of force that we roll in 4 side is not equal so the ball move not in the same direction and I think the wind effect to the ball so it get in different direction too.
