Mechanical Weathering by sparkleplenty1

Mechanical Weathering

170 / 365
I actually took this photo to show to my science classes. We've been studying mechanical and chemical weathering. After school, I took this photo to show how plants can cause mechanical weathering and break apart bricks, walkways and sidewalks. My students never seem to believe that something as simple as a plant can break apart brick and mortar.

It still amazes me to this day that plants are so tough. :-) Nice photo

You teach 5th grade? I think? We teach that in 5th grade in my state.

@5unflow3r Thanks Trina - Yes - plants are that tough!

@espyetta Yes, MaryBeth - We teach that in 5th grade - and the kids really seem to grasp the concept. Chemical weather is a little harder for hem to grasp!

@jgpittenger Thanks, Jane - I love when I can use a 365 photo to use in a science class!

@5unflow3r Trina - I know exactly what you mean - the hormones really start to kick in - mood swings, teariness, loss of best friends, etc, - it's hard for the kids at the end of the year. My kids are moving on to middle school, and while they're excited, they don't want to leave their elementary school where they been for so long! lot of emotional upheavals!

@5unflow3r They totally change! I used to teach "pull out" or resource room gifted ed....I had different grade levels come to me in small groups. My 4th graders would roll their eyes at how my 5th graders would act outside my "mobile unit" waiting for their class or how they acted if they came in...then, they'd turn into that same thing the next year when I had them! I would remind them "Hey! You used to be fine...it has to be you, not me...you saw how it went last year." haha They would just laugh

great shot of the wall being weathered, and year 5 is a tough one - we have that move up in year 6, so aged 11 and they find it tough here
