High Impact Car Race Result

What did we do?

It was a fair test because all the group get to choose the angle we want for the slope and we all have the same car to have a fair test and we get to choose the stuff we put to our car and we have the same time to put modification to our car and we have the same track,our car's fastest time was 1.02 seconds

The first modification is this.I put clay on the front that shaped aerodynamically and i put spoiler at the back to make the forces balanced,I put shark fin near the spoiler so that it makes the car less air resistance to make the car fast.




                                                                                                                                                                 

The second modification is this.I put more clay at the back of the car to make it slower so it can stop on the green line and add more air resistance.

For the third modification we didn't change any thing and I think it will work.





The results of the race:
Our car is the 7th car on the list, our first try on our car passed the green line by the time 1.27,the second time is 1.2 seconds                                                                                                  
















Our first try on the second didn't get as close to the green line as possible because about .3 meters away from the slope but,the second one is more closer to the green line about .45 meters away from the slope.

We won the third race by 4.97 meters away from the slope.

The cars who won:

Kete

What we have learning about:

We have been learning about the different forces and we choose the force push and pull
I found out that there are different kinds of forces and one of them is push and pull

What I have learnt is how many forces do we have
How it show my learning it shows my learning because i have insert photos of it.

Vortex canon

Aim: to see how far our vortex canon can shoot.

Equipment:

• plastic bucket
• garbage bag
• sellotape
• cardboard
• plastic cups

Method:

1.Cut a hole at the bottom of the plastic bucket.
2.Put the garbage bag at the top of the the bucket.
3.Stick the cardboard to the bottom of the box.
4.Fit the cardboard in the bucket.

Results:
The vortex cannon we made was strong and it knocked the cups 3 meters away


Discussion:
A vortex cannon can shoot cups in 3 meters.

We think that our team could improve on making the garbage bag around the bucket even more tighter, this might help us knock out the cups from a further distance.

The Science of the wind

WIND BLOG:

What causes the wind?

Wind is cause by the pressure in the atmosphere.Its is the flow of gasses on the large scale,there are some long duration wind and they have various names like breeze,gale,storm and hurricane.Wind is motivated by human mythology,and it s used to make power source too.







What is the physics of the wind?

Wind is caused by weight in the air.As the cold air is heavier that warm air,The pressure of the cold air drops.



The list of good affects of the wind.

• It pollinates the plants.
• Wind change the weather.
• Wind makes the windmill go.

The list of bad affects of the wind.

• It causes tornadoes.
• It causes the movement of the allergens ( pollen,mold)
• It causes waves
