Twenty questions make up an assessment designed to test super scientists' knowledge of ecosystems. Scholars answer multiple-choice and short-answer questions about organisms, food chains, energy flow, and more.

Students complete food chains for organisms in three environments. They use copies of the Habitat worksheet. Students review the food chain terms with the teacher. They research related food chains, and interlink these to form a food...

In this food chain worksheet, students write in the steps that show how energy flows through a food chain, from producers to consumers. This worksheet is a graphic organizer.

Learners of many ages discuss how all organisms rely on other organisms for their survival. They construct a food web and energy pyramids, and write an informative essay about the food web that they have designed.

Young scholars perform an activity in which they discover what happens when food chains overlap in an ecosystem and discover the three components of a food web.

Pupils compose a visual representation of the food chain cycle using Inspiration educational software.

Students visit an interactive web page. In this food chain lesson, students visit an interactive web page displaying an example of the food chain in Antarctica. As students move their mouse over the images, captions appear describing the...

Young scholars use the EcoKids web site to explore food chains and the associated terminology. They answer the questions about food chains and their importance. Students use the Kidspiration program to add information to an Animal Fact Web.

Thirteen short-answer questions follow a brief food web activity in a formative assessment designed to test knowledge of ecosystems and the energy that flows through them.

It is a tangled web the ecosystem weaves. Learners begin an activity on ecosystem interactions by building a food chain and then a food web with yarn as a group. To finish, they research local environmental changes that may impact the...

In this food web crossword puzzle learning exercise, students use the 23 clues to identify the correct terms that will solve the crossword puzzle.

In this food web word puzzle worksheet, students examine the 24 words and names in the word bank and locate them in the word search puzzle.

Students make lists of producers and consumers and act as consumers that eat producers in a garden. In this producers and consumers lesson plan, students demonstrate a food chain by using a piece of yarn to connect all of them together.

For as small as they are, plankton sure play an enormous role in maintaining marine ecosystems. Dive into an investigation of these tiny organisms with a hands-on life science activity in which children cut out pictures of sea...

Students consider why we eat and where our food obtains its energy. They illustrate food chains that might be found on an open field, dissect owl pellets, identify the remains of animals in the pellets, watch videos and participate in...

Students identify the relationship between predator and prey in the food chain. In this food chain lesson, students work in groups and play a predator and prey game. Students discover what happens when a predator does not find prey. 

Students produce a newspaper covering topics related to food webs. They use print and electronic sources to gather information about specific animals. They share their information with the class.

Students investigate the dietary habits of living organisms by creating a model food chain.  In this food web lesson, students define several food chain vocabulary words such as omnivore, carnivore and herbivore.  Students...

Third graders examine the difference between a food web and food chain. They also examine the importance of the sun in a food web and food chain. Students understand what happens when you remove parts of the chain.

The class will make observations to determine how environment has shaped the way particular birds and fish eat. They will view a series of photographs, read two short articles, and then consider how food availability has determined how...

Students examine the different plants and animals in British Columbia.  In this forest ecology instructional activity students explore how ecosystems work, classify animals and investigate food webs and chains. 

Students recognize interdependence in a food web by using yarn and notecards to create a food web and discussing what would happen if one of the organisms from a certain trophic level is removed.

Students describe the importance of having a balance ecosystem. After a brief lecture, students give an explanation of the properties of an ecosystem. They create a web, using yarn which shows how the various members of the ecosystem are...

Young scholars explore animal and plant adaptation.  In this ecosystems science lesson, students view websites to gain information about plankton and its  interdependence within ecosystems. Young scholars identify ways in which...
