Here at Trap Pond You will learn about:
• Science – Soils and how they support Ecosystems– pH in soils– Freshwater Ecosystems
• Geography/Social Studies– Mapping ecosystems– How people impact ecosystems

What is in the soil?• Soil is made up of both living and non living materials• Soil has decomposing material such as leaves, bacteria, and dead insects• Soil contains living material such as plants, animals, and fungi• Non living materials such as rocks, minerals, and metals• The mixture of all of theses components is what is in the soil.

What is in your soil?
• With an adult go outside and make some observations on the soil around your home or school.
• Draw or write three observation of your soil.

Soil Layers
A soil horizon is a layer of soil.Which layer of the soil do you think has the most nutrients?
![Page 7: 5 th Grade Field Trip to Trap Pond State Park](https://reader038.vdocuments.us/reader038/viewer/2022110403/56812b9b550346895d8fbe02/html5/thumbnails/7.jpg)
Layers of Soil
The soil layers tell a story of the past. The soil layers canprovide insight into the history of the soil.

Soil Types and Textures
Different soil types and textures support different plants and animals.The Shore Line, The Forest, The Beach, The Swamp, or a field all support a few of the same but mostly different plants and animals.

What is pH?
• Soil pH is a measure of the acidity or alkalinity in the soil.
The most common classes of soil pH are:• Extremely acid 3.5 – 4.4• Strongly acid 5.1 – 5.5• Moderately acid 5.6 – 6.0• Neutral 6.6 – 7.3• Slightly alkaline 7.4 – 7.8• Moderately alkaline 7.9 – 8.4• Strongly alkaline 8.5 – 9.0

Soil pHSoil pH influences the
mixtures of nutrients. It also
affects the activity of micro-
organisms that
Break down organic matter.
Soil pH affects what nutrients
a plant can take from the soil.
• A pH range of 6 to 7 is
generally best for plant
growth.
However, some plants have
soil pH requirements
above or below this range.

Plants need certain pH to grow properly

Freshwater Ecosystems
• All Communities thrive on and depend upon food
for their survival. The energy in food is what
fuels the processes of life. Energy and nutrients
are passed from one living thing to another in the
food chain. Energy only passes one way through
the food chain but are recycled over and over.
![Page 13: 5 th Grade Field Trip to Trap Pond State Park](https://reader038.vdocuments.us/reader038/viewer/2022110403/56812b9b550346895d8fbe02/html5/thumbnails/13.jpg)
Every food chain is interconnected, forming a complex arrangement called a food web. Every food chain begins with the sun. Green plants and algae, in the process called photosynthesis, “Captured” sunlight. Plants make their own food therefore are called producers.
![Page 14: 5 th Grade Field Trip to Trap Pond State Park](https://reader038.vdocuments.us/reader038/viewer/2022110403/56812b9b550346895d8fbe02/html5/thumbnails/14.jpg)
All other organisms must eat plants or animals in order to obtain the energy and nutrients they need to survive. These organisms are called consumers.
The organisms that eat dead and decaying organisms and then recycle the nutrients to be used by a new generation of plants are called decomposers including insects, worms, bacterial and fungi

Freshwater PondCan you identify a producer, consumer, and a decomposer?

Freshwater Ecosystem Food Web
How many different food chains can you
identify in this food web?
Hint: Sun
ProducerConsumer
Decomposer

Can you identify a food web within the Macro invertebrates of the pond?Hint: Some insects eat other insects.

An Example of a Salt Water Food Web
What are some ofthe different organism in a salt water food chain?What organisms arethe same?

Human Impact on the PondOrganism within the pond rely on the plants that grow in the pond. Plants provide food and shelter for insects and animals that live in or around the pond. When humans use the pond for recreation, for example, it can impact ecosystems.
![Page 21: 5 th Grade Field Trip to Trap Pond State Park](https://reader038.vdocuments.us/reader038/viewer/2022110403/56812b9b550346895d8fbe02/html5/thumbnails/21.jpg)
Humans and the EcosystemHumans can protect, respect, and conserve our local ecosystems.
We should understand the impact we have on the ecosystem and its balance.
Within the ecosystem, humans, plants and organisms are all connected.
