Images of Tule Ponds Field Trip

 By Mrs. Lew’s 2nd Grade Class (March, 2009) James Madison Elementary School, San Leandro

We enjoyed the Tule Ponds nature walk
And listening to your interesting talk.

So many plants we saw and touched
Like sycamore leaves, tule, and such.

We smelled freshly picked bay leaves
Lavender bush and California poppies.

Adventurous ones who were unafraid
Tasted sour grass by such a blade.

We didn’t know that the willow tree
Was the natural headache remedy

A milkweed seed pod went “pop” with ease
Seeds floated like a parachute on the breeze.

In the greenhouse like growing seeds
We felt the mist and warmth it needs

The animal life was so amazing to see
Painted lady butterflies and honey bees

When you lifted a log to see what breeds
We saw bloodworms, roly-poly and centipedes.

The skunk den, raccoon bones and crayfish claw
Were animal evidence that we saw.

We found milkweed beetles, mosquito fish,
Yellow-eyed bullfrogs that go splish

Walking quietly with sharp ears, we heard
Ducks, coots, blue jays and a red-winged blackbird.

You showed us new things, like an osprey,
Catkins, and a home made of tule.

The irrigation tunnels were cool to explore,
We’ve never yelled in one before!

We learned so much and enjoyed our stay
Tule Ponds field trips was awesome day!



At the facility (DISCONTINUED FOR 2020):  We have 112 free classes for schools in Alameda County.  Please state your name, school, district, grade, how many children, and preferred date and time (9:30-11:30; 12:30-2:30)(schedule is flexible if school is traveling).   Please register early for free classes, they fill up quickly.    Note no more than 5 classes per school or one grade level.

The field trip is an exciting experience for students and teachers alike.  Unlike most nature areas, students are able to touch and experience an urban wildlife.  The area is dissected by the Hayward Fault  and is one of the oldest natural lakes in the East Bay (over 4000 years old).  This 17 acre facility is only open to school groups with occasional public tours.  The wetland is only 100 feet east of the Fremont BART station.  The classroom has 4 lab areas, for a true hands-on science experience. 

 Please email for quick response.  Also  to see virtual days.  If it says Tule on a date, it is taken so please request another date.  Also we would need to confirm (we sometimes have other things going on with staff.)  Thank you.

These trips are paid for by Alameda County Flood Control and Water Conservation District.  Math Science Nucleus manages the facility for this agency. If you are out of Alameda County or we no longer have any free trips available, you can still schedule a trip for $200.00.
