The three objectives of this project are to have students prepare a wet mount slide, use a microscope to locate organisms in the pond water and identify the organisms in different regions of the pond water. The first material is pond water, which you can obtain from your local pond or you can purchase through a science supply company.
The other materials are microscopes, slides, cover slips, droppers and paper towels to clean up afterward. The procedure is as follows:. Teachers can ask these discussion questions:. Students should clean up work stations.
All lab material should be cleaned and dried and returned for storage. To grade this project, teachers can evaluate the effort put into the sketches, answers to discussion questions and how well the students participated in the project.
To branch off of the aforementioned project, students can compare their own sketches to this organisms in pond water chart. Students will use this chart to help identify and name the different types of organisms. Teachers can assign an Internet project in which students can find information about the organisms and see where they fit in a food chain or food web. Students can identify these organisms as producers or consumers. Students should print out above chart and cut out the pictures.
They can use these pictures to help build a food web. The two objectives of this second project are to identify the role of the organisms in a pond water community and to correctly place organisms in trophic feeding levels on a food web. To grade this project, teachers can evaluate if the students are correct in their identification of the organisms, if the organisms are correctly placed in the food web and the effort of neatness put into the project. Thank you to high school biology teacher, James Murphy.

Project One: Pond Organisms The three objectives of this project are to have students prepare a wet mount slide, use a microscope to locate organisms in the pond water and identify the organisms in different regions of the pond water.Peer into an underwater world.
In this cool science fair project, discover how tiny ocean life feeds some of the largest animals on the planet. Whales are one of the most recognizable marine mammals, and people love to visit the Pacific Northwest to go whale-watching. One of the most famous whales in the Pacific Northwest is the killer whale, or orca.
Some of these black and white whales eat fish, but others, known as the transient orcas, eat other marine mammals such as seals. Transient orcas move from place to place, while resident whales stay in the same general part of the ocean.
These marine mammals like to munch on fish as well—usually fish like herring or salmon. What do little herring fish eat? They survive on plankton —the tiny, drifting animals and plants in the ocean. There are two broad types of plankton: phytoplankton is a plant, while zooplankton is an animal. They forage on other plankton, algae, dead plant materials, and bacteria. You may have heard the terms food chain, food web, and food pyramid.
What do they mean, and how are they different? A food chain is a simple chain that illustrates which organisms eat which. In a food chain, you begin with one plant. In the ocean, this might be one of the very abundant phytoplankton. A grazing copepod might eat the phytoplankton, and a herring would come along and eat the copepod for lunch.
After that, a seal looking for its supper would find a few delicious herring and munch on them. If you wanted to go further, you could add your orca whale into the food chain, which likes to eat the seal.
Of course, the menu in the ocean is a lot larger than what your food chain shows!
Individual animals can eat many other types of plants and animals, not just one. For example, a seal likes to eat other fish like salmonand seals in turn can be eaten by larger animals such as orca whales. A food pyramid is different from a food chain or web. How is it different? Think about your herring. How many copepods does it eat in a week? Probably thousands!
How many herring does it take to feed your seal? Certainly fewer.
As you move up the food chain, each level, or trophic level, can support fewer animals. Each trophic level represents the position an organism occupies in a food chain. A single seal ultimate consumer can eat many herring secondary consumerand a single herring can eat many copepods primary consumer. Each copepod eats hundreds of individual bits of phytoplankton, called producers because these small plants get energy from the sun.
This means that thousands and thousands of plankton end up indirectly feeding that seal at the top of the chain. A food pyramid shows the different numbers of organisms that are necessary at each level of the food chain.Luisa cabeza lleida
At the bottom of your food chain you might draw many different bits of phytoplankton, but there will be only one seal in the small triangle at the top. Bookmark this to easily find it later.Brine shrimp populations survive in some of the harshest environments.
Subject brine shrimp cysts to extreme conditions then try to hatch them to see just how tough they are! Students will design and conduct an experiment to test the effect of acid rain on the germination of seeds.
They will utilize the data from their experiment to explain their conclusions, and also read a passage on acid rain. In this investigation students will study the types of bacteria that grow during the formation of sauerkraut, identify some characteristics of each, as well as research the type of respiratory pathway used by the organisms to break down the cabbage to get their energy.
Students can see how the contamination levels increase as the trophic level increases. The objective of this lab is to put together a suitable habitat ecosystem that will allow one or two guppies to survive to the end of the school year and beyond. Students will make observations of their ecosystems for the three weeks. This series of four different lab activities all relate to flower reproduction.
They have been designed to relate to each other and to stand alone. Name that Pollinator focuses on adaptations for successful pollination. Both pollen and pollen vectors are examined. What can a skull tell you?
A lot! This activity uses soda, ice cream, sprinkles, colored sugars, and food coloring to represent the layers of Earth and aquifers under the surface. In this activity, students investigate food chains by assuming the roles of animals that are part of a food chain.
This investigation examines natural selection and coevolution using goldenrod Solidago canadensisits stem gall insect Eurosta solidaginisand associated parasites, parasitoids, and predators that feed upon the stem gall insect i. Students will learn to recognize moss and lichens, identify various trees, record observations using a mapping technique, use a compass, and think about the conditions mosses and lichens need to grow.
This lab presents a popular method often used to estimate the population size of a single species of highly mobile animals, such as insects or vertebrates. Students use other students in the school as their population and the Lincoln-Peterson method to determine population size.
Students assume the role of an ethnobotanist for a start-up pharmaceutical company, who is about to journey to the rainforest, coral reef, or another natural source of medicine in the world. Their mission is to catalog 1 plant or animal species that may be useful to medical research. In this lab, students will be introduced to the concept of a dichotomous key through the use of preliminary activities modeled by the teacher. Search: Search Filters: This Site.

Battle-jar Galactica- Matt Downing CIBT Alumni Workshop Ecology High School Microbiology In this investigation students will study the types of bacteria that grow during the formation of sauerkraut, identify some characteristics of each, as well as research the type of respiratory pathway used by the organisms to break down the cabbage to get their energy. Hosted by CampusPress.I use this lesson model because it peaks the students' interest in the beginning during the "Engage" portion and allows for the students to actively participate in the investigations throughout the subsequent steps.
In this Unit students will learn about ecosystems and the transfer of energy through ecosystems. The lessons in the unit are primarily based on our local ecosystem- the Santa Monica Mountains. This area is known as a Mediterranean Ecosystem or Biome and we will learn about the plants, animals, climate, and human impacts on this area.Pcb manufacturer malaysia
In this lesson, students will create Food Webs based on the previous lesson's Food Chains that they created. They will also make a card representing an organism in a Food Web and we will create a model of a Food Web. Support an argument that plants get the materials they need for growth chiefly from air and water. Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants.
Organisms can survive only in environments in which their particular needs are met. A healthy ecosystem is one in which multiple species of different types are each able to meet their needs in a relatively stable web of life.Food Chains & Food Webs - Ecology & Environment - Biology - FuseSchool
Newly introduced species can damage the balance of an ecosystem. Organisms obtain gases, and water, from the environment, and release waste matter gas, liquid, or solid back into the environment. A system can be described in terms of its components and their interactions. Modeling in 3—5 builds on K—2 experiences and progresses to building and revising simple models and using models to represent events and design solutions. Use models to describe phenomena.
Engaging in argument from evidence in 3—5 builds on K— 2 experiences and progresses to critiquing the scientific explanations or solutions proposed by peers by citing relevant evidence about the natural and designed world s. Support an argument with evidence, data, or a model.
I start this lesson by asking the students what they think the difference is between a Food Web and a Food Chain. I list their responses on the board. Since we have already learned about the Food Chain, the students have more responses about this concept.Geek hacker
I remind the students that a food chain only shows one direction of energy flow based on one organism. For example, energy comes from the sun, to green plants, to animals that eat plants, and to animals that eat other animals.
When animals eat green plants and other animals eat those animals, the energy moves from one living thing to another along the food chain. Students will learn more about how the amount of energy passed along from each "trophic" level decreases in later grades but it is helpful to introduce this concept to the students. We also review the vocabulary Animals that eat plants are called herbivoresanimals that eat both plants and animals are called omnivoresand animals that eat only other animals are called carnivores.
All members of a food chain depend on the energy from the sun that green plants transform into food energy. I also remind the students that the green plants are producers and that the animals that eat the plants and other animals are the consumers. This is one of my favorite activities to explain the food web and a classic. I have the students prepare different cards that include plants and animals from our local Mediterranean Ecosystem since we will be doing more activities with these organisms in a later lesson.
I also make a card with a picture of the Sun. I have labeled each card and have handed each student a different one.To get the best possible experience using our website, we recommend that you upgrade to latest version of this browser or install another web browser.

Tropical Rainforest Food Web. Kids build a rainforest food web to explore trophic levels in this cool science fair project for 4th grade. Effect of Food On Mosquito Growth. This experiment researches if you gave different amounts of food to mosquito larvae would they grow faster or slower.In this activity, students research a plant or animal of their choice that is found in their local ecosystem.
To demonstrate their new knowledge about its link in the web of life, students will create a technology-based learning tool and an accompanying model. As a group, make sure students choose a variety of plants and animals, including mammals, insects, birds, reptiles, fish, fungi, trees, and other plants.
Remind them to avoid domestic animals such as cows, dogs, cats, chickens, etc. After selecting an organism, ask students to work in pairs and discuss their chosen plant or animal, its place within a food web, and relationships with other plants and animals. Refer to your PreK-8 Guide for some guiding questions. Essential Question: What happens when a plant or animal is removed from a food web? It is important for students to understand the difference between a food web and a food chain.
To explain these concepts, you might share these video clips from Bill Nye, explaining food webs and Brain Pop, explaining food chains or assign them for homework. You can also refer to your PreK-8 guide for an explanation. Next, ask students to use the Internet to search for images, videos, and other content to build their knowledge about their chosen organism. BioKIDS is a great place for students to start. Using this tool, students can drag and drop lines between organisms to show the interactions between species.Journal entries questions pdf
With knowledge about the structure and function of a food web, students can gather information from their individual research and create a video documentary about their organism and its interactions with other species. The video can be created and filmed individually or collectively.
Students should be responsible for sharing the role their chosen organism plays in the ecosystem. They could use props, printed pictures, or act out various roles, to accompany their narration. When complete, these learning tools can then be shared with the entire class. Guide students in the creation of a mobile, with each hanging piece representing each of their chosen species. After constructing the mobile, take a close look. Does it balance? Are the pieces arranged to tell the story of your food web?
Consider challenging students to design a solution to replace a key species, if it was ever eliminated from their food web. What are the advantages to protecting the organism versus constructing and implementing the engineered solutions? Food webs function best when there is an equal balance of all components. Students can apply their math skills to this ecosystem scenario below, which involves balancing appropriate levels of producers and consumers including grass, deer, rabbits, hawks, and bears.
Your email address will not be published. Decomposers live off dead material and recycle nutrients into the soil for reuse by plants.
