Transcript to See Claire`s Soccer Field Runoff PowerPoint

CE2-B, Lycée Français la Pérouse
Comparing Water Runoff from
Synthetic Turf vs. Grass
Soccer Fields
1
The question I want to answer:
 Can
we test different stages of the water
cycle runoff from grass & turf fields to see:


is one more toxic than the other?
could the water hurt plants, people, animals or
ocean life?

Why do I care?
 I’ve
been playing soccer since I was 3
 I like turf, but I see a difference in water
from grass fields – I want to make sure it’s
safe

Literature Review – What do we know?
Ask the Experts – What do they know?
Ask the City – What do they know?
Collect most water samples ever studied on
this topic

Description
Let’s use science to understand what’s in the
water runoff from turf and grass fields
 Let’s understand what this means for kids and
the environment
 Let’s look at what’s good and bad about turf and
grass fields

Grass Fields

Good




Soft, natural, many different uses
Make our parks green, filter storm water
Provide homes for insects and rodents
Bad




Lots of water, pesticides, fertilizer, mowing, seeding
Expensive maintenance, gardening vehicle pollution
No game or practice if it’s wet at all
Injuries

Synthetic Turf Fields

Good

Ok in wet weather: 2-3 times more games than grass
• especially in wet cities like SF




Requires little water, no pesticides, little maintenance
Fewer injuries
Costs less (total)
Bad:




Costs more at first, compared to grass
Gets really hot in hot weather
Crumb rubber gets into everything
Toxic chemicals (older fields), bacteria?

My Study of Turf and Grass Runoff
 We’re

looking at 100 water samples
Taken from 5 grass fields and 5 turf in SF
 We’re
looking at chemicals, bacteria and
other issues

What do these mean for living things?
 Plant

and Animal Study
See what happens to them in that water

Procedures

Suck water out with syringe


If too hard to get water, add sterile water
Put into sterile vials and label each

Keep a journal and notebook
 Look at the water with my microscope


Take pictures & movies
Next:

Go UC Santa Cruz lab and figure out different ways to
look at the water and what’s in it
