Title:THE 2 FANCY SCIENTIST!

BY:RICKI AND KHAILEY

QUESTION:

WHAT WOULD HAPPEN IF WE LAYERED THE SOIL INSTEAD OF MIX?

HYPOTHESIS:

I THINK THAT THE SOIL WILL WASH AWAY QUICKER THAN THE MIX.

MATERIALS:

SOIL,WATER,STREAM TABLE,CLAY,AND SAND.

SET UP

LAYER SOIL

WE ADDED SOIL,SAND,CLAY,THEN WATER.THEN WE ADDED A 1 LITER CUP WITH 1 BIG HOLE.

AFTER LAYERED SOIL.

once we added water to the layered soil we saw a big difference.

Conclusion:

When we compared our stream tables we noticed that the mixed soil had more erosion but more of the layered soil eroded faster.

Evidence:

WE NOTICED THAT THE MIXED SOIL HAD MORE EROSION BUT THE LAYERED SOIL ERODED FASTER THAN THE MIXED. HOW WE FOUND OUT THAT THE LAYERED SOIL ERODED FASTER IS BECAUSE  RIGHT WHEN THE WATER HIT THE CUP MOST OF IT WENT DOWN IN 2 SEC. AND THAT'S HOW FAST IT WENT!

WE NOTICED THAT THJE MIXED
