My Blogs!
My first blog wasnt done very well to be honest,because it seemed as if though i rushed through it.Although my second one was a little too short I think it was good and I think my opinion was very understandable.My fifth blog was accurate and I believe I did very well on it.I had well expressed ideas and my answers were complete.So for that reason my favorite blog was the fifth one I wrote.In order to prevent having metioker responses I shouldnt rush through them and I should try to have lengthier responses.

Mixture
Jennifer didnt create much.She only created a physical mixture which is when it can be seperated.If you simply poor the water into a paper towel, it will act like a filter.The salt or anything else will not go through, but the water will.This proves it can be seperated.So therefor it is a physical mixture.

Design Squad
The Design squad was challenged to transform a tricycle and a wagon into a drag racing car.They had to make the wagon and tricycle move on its own by attaching power drills to them.They also had to make sure the weight of the driver was as light as possible so the dragracer would'nt slow down too much.The blue team used the strategy of using a spool connected to both set of wheels so the speed would accelerate up.The two teams worked well together because everyone listened to eachothers ideas.They also worked well together by keeping possitive attitudes majority of the time.
If I were in design squad I wouldve went with the blue teams idea.Although I would've used a telephone wire because of the tecture.The only reason they lost was because the rope was tangling.The drag racer was just about to speed up when the rope was tangled.The type of rope was the only hold up.I learned from this episode that different types of string and rope function in two different ways.

Noble Gases of Group18
The noble gases of group 18 dont form chemical bonds, because other than Helium, group 18 has 8 valences.Having 8 valences is very rare.Atoms that have 8 elctrons on the outer leveldont form chemical bonds.If that energy level has 8 valence electrons it is considered to be full.A atom that has less than 8 valences more likely to form bonds.All atoms form bonds by gaining,losing,and sharing elctrons.
