Lesson Plan
Tule Ponds at Tyson Lagoon

if you want to go over Tule Ponds with a booklet please download the following booklet.


1. Students explore  the changing landscape at Tule Ponds at Tyson Lagoon
2.  Students explore the life cycle of plant and animals that live at Tyson Lagoon.
3.  Students observe plants that reproduce through seed formation.
4.  Students observe birds and explore family units.
5.  Students see how soil is made for use with native plants.
6.  Students observe native and non-native plants.


              adapt - changes that take place in an organism that allow the organism to live and survive better in a certain environment
aphid small white insect that eat leaves
        chrysalis covering that a caterpillar uses to change into butterfly (note:  a cocoon is the term for moths)
larva in insect terminology, the wingless, early stage of an insect before it changes
        leaves - the principal lateral appendage of the stem of the plant, which functions in photosynthesis and transpiration
        metamorphosis in many animals they go through a change of shape within their life cycle
nymph an aquatic stage of  some insects that have incomplete metamorphosis
petal the part of a flower that is often brightly colored or ornamented and is used to attract insects for the purpose of cross pollination
        pupa - The non-feeding stage between the larva and adult in the metamorphosis of  insects
receptacle expanded tip of a flower stalk or axis that bears the floral organs or the group of flowers in a head.
        seed pod multiple seeds in a structure found on some plants
        stamen - the pollen-producing reproductive organ of a flower
       stem - the part of the vascular plant axis that bears the leaves, auxiliary buds, and flowers, all comprising the shoot
        taproot - main root of a plant growing straight downward from the stem
wetland - a low area where the land is saturated with water


The organisms at Tule Ponds at Tyson Lagoon continuously change throughout the year.  Organisms have their own unique life cycle over time.  Some birds can be found only during their nesting seasons, while others can be seen all year round.  Frog eggs will produce tadpoles, which are abundant during the spring   Ladybugs eggs are found in May and June that rapidly change into pupa and then ladybugs.  Dragonfly nymphs are abundant in the water, and change into dragonflies in a two-year cycle.

The climate plays an important factor for these organisms.  During the winter it is very wet, but during the summer some of the ponds may dry up.  Plants and animals must adapt to the changing conditions. 


1.  Discuss Tule Ponds as a wetland area that was constructed by engineers to clean stormwater.  It changes throughout the year.  The ponds become full during the rainy season because water comes in through storm drains.  The water level is high and brings many organisms to the area. Migratory birds are abundant at Tyson Lagoon.

2.  Tyson Lagoon is a natural wetland.  It is a sag pond caused by the Hayward Fault.  It does not dry out, and more stable environment.  Fish live there and aquatic plants are there all year.  Use the picture in the booklet to go over Pond A, B, and C and Tyson Lagoon.

3.   Go over the different life cycles that you can find at Tule Ponds and Tyson Lagoon.  The examples in the booklet are only a few examples of different types of changes from metamorphosis to incomplete changes. 

Ladybugs eggs are mainly found in late spring to early summer.  Frogs are found all year, but tadpoles are more abundant during late spring.  Dragonflies and damselflies are more abundant during the summer, but their nymphs can be found throughout the year.  Butterflies are found mainly in spring and summer, and we currently do not have any abundant other stages. 

4.  Instruct students to go outside and find the different parts of the poppy seeds (if available). They are most abundant during late winter- summer. 

5.  As students walk through the facility the different plants and animals that show change will be discussed.
