Proving microscopic structures exist is a difficult task. Learn how scientists did just that in the mid-1800s as they set out to identify the cellular structures related to genetics. The online lesson explains the collection of work that...

Students view a video clip about animals and their habitats. They work together to discuss how different animals adapt to their environments. They create a new habitat for a specific animal and draw new adaptations for them.

Three activities introduce upper elementary ecologists to photosynthesis and food webs. In the first, an experiment is set up to determine how plants respond to different types of light. In the second, they connect organism cards with...

Students enter personal information into a database. The information is used to reinforce the ideas of inheritance that is found in 1st Grade Science. Access to technology is essential for this lesson. Adding the use of a mirror for...

Alphabet insects! Who has ever heard of such a thing? Get ready because your class is going to research insects that start with a specific letter of the alphabet. In small groups, they'll use the Internet and reference texts to locate...

What is biogas and how is it made? After examining background information about the sources of biogas and biogas generators, class members follow the provided information and build a biogas generator that can be used in the...

Learners observe organisms found in pond water with a microscope. In groups, they discuss how single-celled organisms satisfy their needs for food, water and air. They compare and contrast the needs of macroscopic and microscopic...

Students observe aquatic plants and animals and identify their systems. In this plants and animals lesson plan, students compare systems of organisms and orally express how plants and animals rely on each other.

Students identify the various ways water move throughout the earth as part of the water cycle. For this science lesson, students gain a knowledge of basic science concepts related to everyday life through patterns and how they repeat as...

Students study organisms and the roles they play in nature. In this ecology lesson, students photograph several examples of organisms during a nature walk. Students print out their photos and classify the organisms as plants or animals.

Fourth graders show the needs of plants met by soil. In this Science lesson, 4th graders detail the components of soil and determine which are living or once living and non-living. Students determine the needs of plant growth that are...

This presentation begins with the many problems multicellular organisms which rely on diffusion encounter. There are many diagrams of mammalian organ structures, and they are labelled with their relevant functions. This an excellent...

Students conduct an experiment to determine whether plants need air in order to survive and grow. They discuss natural resources, analyze slides, and observe and record data from the experiment.

Young scientists use the Internet to evaluate how organisms are classified. They research the phylogeny of organisms and how they are linked in a certain way. Pupils hone research technology skills with their final presentations.

First graders learn the basic needs of plants, label the major parts of a plant and name their uses. They also use a KWL chart.

Young scholars observe organisms found in the water. In this instructional activity on organisms, students collect water from local streams and tributaries in order to study the organisms found in the water. As a culminating activity,...

Middle schoolers are introduced to classification and some of the difficulties surrounding classification and how classification systems need to be able to adapt and how they may need to be changed when new information is discovered. ...

Students explore the parts of plants and discover that plants need to grow. In this plant lesson, students discuss the parts of the plant and plant petunias. Students can share their plants with friends or families.

Explore the concept of evolution and cell biology; your class can work in groups to use the internet to view websites on evolution, take a quiz, and complete a lab activity.

Young scholars investigate the similarities and differences of living things. Specifically, students will be able to identify the life processes of photosynthesis and describe the basic needs of plants.

Second graders observe images of prairie ecosystems and discuss the needs of living things. They create a prairie habitat in a closed jar to observe the water cycle and plant growth.

Young scholars use video, Internet research, graphs and tables, worksheets and hands-on experiments to investigate the properties of water in a lake environment. They work under direction or through an inquiry process.

First graders examine the lifestyle of classroom and family pets in their natural habitat. They determine the needs of plants and animals, and how those needs are met. They listen to read alouds, sing songs, and draw using computer based...

First graders describe what help seeds need to grow, including light, water, good soil, and warmth, observe and discuss what happens when seeds do not have help, and state similarities and differences among seed growth.
