Students participate in a virtual field trip to Lake Superior. In groups, they perform experiments in which test the level of toxins and bacteria in the water. They also watch video segments life in the lake and discuss their observations.

In this measuring worksheet, students determine the mass shown on the scale, review how to read measurements in a graduated cylinder, and determine which measuring method is more precise. This worksheet has 5 short answer questions and 5...

Fourth graders distinguish between acquatic and terrestrial organisms. They label animals as producers, consumers, and/or decomposers.

Fourth graders create an ecosystem as a class. They have already produced smaller ones. They use a pond or something similar on school grounds to meet the needs of certain plants and animals of their ecosystem. Specifically created will...

Students explore DNA structure using materials such as Twizzlers, small colored gumdrops and/or toothpicks.

Students closely observe the natural world, record data, and notice patterns as the seasons unfold, they build a deeper understanding of seasonal change! The definition of phonology is the focus of this lesson and how it changes...

Students watch videos and fill out worksheets about the turtles and their journey to the Costa Rican beach. In this turtles lesson plan, students learn and discuss survival, predator and prey, and stages of development.

Young scholars research various birds of prey on internet by following a worksheet with specific questions. Students answer questions on worksheet and write short response after completing research.

Learners conduct an experiment to demonstrate how fruit fly populations are controlled by spiders. They observe a variety of environments with fruit flies and spiders and consider how vital spiders are to controlling the insect population.

Students examine NASA's SeaWiFS Project Web site to explore how the SeaWiFS Project monitors environmental and climatic changes in the oceans and atmosphere. They answer questions and write a summary in support of continued funding for...

Students predict the effects of water, light, and soil on the development of a plant and then design an experiment to test their predictions.

Learners use the Internet and other resources to find insect common names that begin with each letter of the alphabet. They write a brief description of each insect, focusing on what the insect eats and where the insect lives.

Third graders complete activities to become familiar with the content and vocabulary related to biomes and ecosystems in order to mainstream into the classroom.

Fifth graders examine animal adaptations and how they meet their needs in a variety of environments. They discuss how they might adapt to their own environment before discussing how an animal could adapt. Next, they complete an...

Students use their personal knowledge and the Internet to discover where and how spiders live. In groups, they discuss their experiences with spiders and how their lives differ from other insects. They use new vocabulary to discuss their...

Pupils examine the white shark. They think critically about a set of shark facts and predict whether the statements are true or false. Students describe a year in the life of a white shark living in the Red Triangle. They create a...

Students identify and discuss the adaptive characteristics and behaviors of fish. They view slides of fish, and design and create a model of a fish of the future, listing the ways their fish adapt to survive.

The following is a tutorial of food chains, food webs and food pyramids.

This lesson, supported by the provided power point lecture (LESSON 1 and 2 Ecology Lecture Supplement ), introduces students to the concepts of food chains and food webs. Through its use, students learn the difference between producers...

Young scholars will build a food web diagram and illustrate the movement of matter through a series of food chains. Resources include detailed plans, examples of student work, videos of the instructional activity in action, and sample...

Explore the food web in a coral reef with these illustration. Identify the consumers, producers, and decomposers that are located within this ecosystem. Site includes illustration exploring the different food chains as well as questions...

For this lesson, students learn about marine food webs and pyramids, and how energy flows through a marine ecosystem. They then research a marine organism and its role in a marine food web. The class pools their information to create a...

Students construct possible food webs for six different ecosystems as they learn about the roles of producers, consumers, herbivores, carnivores and decomposers.
