Sujay Jul 20, Sudheer Vagvala.To intertwine scientific knowledge and practices and to empower students to learn through exploration, it is essential for scientific inquiry to be embedded in science education. In this unit, students will first develop an understanding of the biotic and abiotic factors within ecosystems, the characteristics and classification of living organisms, and how plants and animals obtain and use energy to fulfill their needs.

Then, students will delve deeper into the NGSS standards by examining the interdependent relationships within an ecosystem by studying movement of matter between producers, consumers, and decomposers by creating models of food chains and food webs.

At the end of this unit, students will study ways that individual communities can use science ideas to protect the Earth's resources and environment. Today, I will open the lesson by posing the question, "What are ecosystems? Students will then explore the meaning of ecosystems by conducting research with their teams. At the end of the lesson, students will reflect and apply their new understanding of ecosystems by participating in a class discussion and constructing a class idea 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. In particular, students will be studying how an ecosystem is a system of biotic and abiotic parts working together. The energy released [from] food was once energy from the sun that was captured by plants in the chemical process that forms plant matter from air and water.

Food provides animals with the materials they need for body repair and growth and the energy they need to maintain body warmth and for motion. Plants acquire their material for growth chiefly from air and water.

The food of almost any kind of animal can be traced back to plants. 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. Newly introduced species can damage the balance of an ecosystem.

To add depth to student understanding, when I can, I'll often integrate ELA standards with science lessons. Today, students will work on meeting CCSS. With science, it is often difficult to find a balance between providing students with as many hands-on experiences as possible, having plenty of science materials, and offering students a collaborative setting to solve problems. Any time groups have four or more students, the opportunities for individual students to speak and take part in the exploration process decreases.

With groups of two, I often struggle to find enough science materials to go around. So this year, I chose to place students in teams of three!

Conservation Of Plants And Animals Class 8 Notes

Picking science teams is always easy as I already have students placed in desk groups based upon behavior, abilities, and communication skills. Each desk group has about six kids, so I simply divide this larger group in half.

To encourage a smooth running classroom, I ask students to decide who is a 1, 2, or 3 in their groups of three students without talking. In no time, each student has a number in the air. I'll then ask the "threes" to get certain supplies, "ones" to grab their computers, and "twos" to hand out papers or whatever is needed for the lesson. This management strategy has proven to be effective when cleaning up and returning supplies as well!

I want to inspire interest in today's lesson and capitalize on student curiosity, so I create a Powerpoint Presentation: What is an ecosystem? On the first slide, I pose an authentic question: What is a ecosystem?We love to hear your thoughts about this post!
