Wind Racer

Science 

Aim: To make a wind racer that moves.

Method:

Collect your equipment.
Cut a plastic bag into a big triangle. (Taping one side so only one edge is open).
Tape the large triangles end onto the bottom of the stick.
use popsicle sticks to make a small stand.
tape that on the other side of your trolly.
use string (Adding some slack) and tie the open side of the bag to the stand.
Make sure everything is stable and go win!

Discussion

When your using wind racers there are four forces that help contribute for them to work. This four fourses are Thrust, Friction, Gravity, and Lift. These forces help us do anything including moving. Gravity helped out wind racer because without it our wind racers float. Lift made sure our boat didn't go underground, thrust helped our wind racer to move and slide, Well Friction stopped the moving.

Conclusion

In conclusion, our wind racer moved only an inch before falling over. I think this happened because the sail wasn't wide enough if it were winder it could have caused more Thrust and Thrust could of made it go farther.

can experirnce

AIM: Today in science we did a can experience. here is what to do


Items you need

Bucket of Cold Water

 Warm Water in a Can

Element 

Hypnosis: there would be a lot of steam

Scissors tons

What you need to do is take a Can fill it up with warm water then place it on an element. Put cold water in a 

bucket or a lunchbox container. When steam comes out of and it is boiling take use Scissors tongs open them out wide and pace a tight grip on the can. Take the Can over to the cold water and dunk it in upside down. Then you can see what happened to you can

Conclusion: Once the can it the water it turned cold and tighter to make the can look crushed. 

This happens because when the top of the soda can comes in contact with the cold water it colds down and

changes to hot to cold making the can tighten.

science

Today we done science and we had to categorize foods on what they look like their chemistry name and weather they where a solid liquid or gas first I decided to do the original names of the foods and next i choose to do the chemistry name next. too my surprise they were all weird but unique names 
I don't really get why there is a science name for all of these food and liquids I cant you call them by there original it would be so much easier for scientist I mean way easier.

I think this is a little bit weird but also genius because it gives more information about it and it helps me understand the unique  calculates and simulates in the liquid and fruit.

science

Aim: To see which chemical 
mix creates the most gas.

Hypothesis: (What do I think will happen)

1.

Materials: yeast experiment
  1. balloon
  2.  sugar
  3.  yeast
  4.  warm water
  5.  fan ole
  6. bottle
My hypothesis I don not think it would rise because I is a bad combination of yeast and water

grab a empty bottle take off the lid pour 2 tea spoons of yeast into the bottle and one tea spoon on sugar into the balloon using a fhanule next ad a little bit of warm water and then attach the balloon to the top and now wait 




2

Materials: backing soda and vinegar


  1.  backing soda
  2.  balloon
  3.  empty bottle
  4.  fanoule
  5.  vinegar


 Steps: 
grab an empty bottle take off the lid use the funnel  put  backing soda into the bottle then put half a cup of vinegar into a balloon using the funnel then attach the balloon to the top and wait

Hypothesis
I think it would work because of the combination of the vinegar and the backing soda would make heaps of gas the  gas would rise to the top to make it blow up


3

Materials: soda water and salt

  1.   soda water
  2.  balloon
  3. funnel
  4. bottle
  5. salt
 Steps:

gap an empty bottle take off the lid and ad soda water to the bottle using a funnel then grab a balloon using a funnel pot the salt into a balloon then attach the balloon to the bottle and then wait

Hypothesis

We new it could work because it would release carbine dioxide.





My images:






Findings:
the first experiment had lots of bubbles and a medium amount of air in the balloon 
the 2nd experiment had a small amount of bubbles but it was the biggest balloon with the most air and the 3rd balloon  had a medium amount of bubbles and a tiny amount of air inside of the balloon My new hypothesis is that the bottle with the less bubbles inside has the most air inside of the balloon




Balloon 3
( 3 tsp baking soda, ½ cup vinegar)
Balloon 2
( 3 tsp salt, ½ cup soda)
Balloon 1
( 2 tsp yeast, 1 tsp sugar )
Balloon Size (cm)
15 cm19 cm8 cm
Bubbles
medium amount of bubblessmall amountlots of bubbles

conclusion 

I liked all the experiments because I showed how you can have the same gas but with different ingredients it can show different results to your answer and I help us with team building
