Most people have heard Earth referred to as "the water planet." With that name comes the rightful image of a world with plentiful water. In photographs taken from space, we can see that our planet has more water than land. However, of all the water on Earth, more than 99 percent of Earth's water is unusable by humans and many other living things - only about 0.3 percent of our freshwater is found in the surface water of lakes, rivers, and swamps. The teacher guide describes our current understanding of water cycling and freshwater issues that affect natural and human communities.

The cells of plants include several parts, such as the cell body, cytoplasm, mitochondria, nucleus, vacuole, cell membrane, cell wall, and chloroplasts. Only plant cells have plant walls and chloroplasts.

The classroom resource provides a slide show that will describe the structures of a plant cell. In addition, there is a sing-along video that students can perform karaoke-style that will help them remember the different structures. After utilizing these two resources, the students can complete the short test to assess their understanding.

In this audio clip, students ask the question: Does air have weight? This is a great clip to engage students in a discussion on mass and density. 

In this lesson, students will observe several phenomena related to the polarity of water molecules. They will observe a demonstration of a paper clip being placed on the surface of the water. Students will place drops of water in an already-filled test tube and on the surface of a penny. They will compare the way water behaves with the less polar liquid isopropyl alcohol and will see how detergent affects water’s surface tension. Students will relate these observations to an explanation of surface tension at the molecular level.

Students will be able to explain, on the molecular level, the effects of polarity on water’s surface tension.

India is home to endangered wildlife like the Asian elephant, tiger, and leopard and approximately 1.3 billion people. Use this set of ideas to engage your classroom in learning about biodiversity and conservation challenges and efforts in India.

Animal cells have many functions that support the life of the animal. Animal cells also have lots of different parts, including the cell body, cytoplasm, mitochondria, nucleus, vacuole, and cell membrane.

The classroom resource provides a slide show that will describe the structures of an animal cell. After utilizing this resource, the students can complete the short test to assess their understanding.

In this interactive lesson, students enjoy zaps, flashes, and bad hair days as they read together with a Gray Crowned Crane about static electricity. Learn to use images when reading to help clarify meaning and improve understanding of an informational text.

In this lesson, the teacher models and describes the kinds of information students will be looking for in their research project on a synthetic product. This is done by using an example of a synthetic product that students make in the classroom: a gel worm (not for eating.) Students make it by combining a sodium alginate solution with a calcium chloride solution. The teacher uses this product to model answers to the three questions students need to answer in their research:

1. What natural resources are used to make the synthetic product?
2. What chemical processes are used to make the synthetic product?
3. What are the negative and positive impacts to society of making and using the synthetic product, compared to making and using a more natural product with a similar function?

Students choose or are assigned a synthetic product to research. They investigate the product to answer the three questions. Students apply their learning to make an advertisement, poster, short video, or article about their synthetic product.

Students will be able to find and analyze information to describe that chemical processes are used to convert natural resources into synthetic materials and products. They will also be able to give examples of how the production of synthetic products has impacts, both positive and negative, on society.

In this activity, students make a meerkat model while identifying unique body characteristics. Students learn how adaptations are crucial to a meerkat's survival.

Humans and animals share some common features. We use our eyes to see, our nose to smell, and our ears to hear. Animals use those same features to help them survive by finding food and sense danger. A Tail Like This will help children learn more about the features of a few common animals they may see every day.

In this Martha Speaks interactive story students discover how plants and animals depend on each other in an ecosystem. Fallen leaves decay; earthworms eat the leaves and fertilize the dirt. Then trees use the fertilized soil to grow. When used as a part of Martha’s True Stories Buddies Program, buddy pairs engage with the interactive story and then talk and write as they draw a habitat they have seen that includes an ecosystem. To familiarize yourself with the program, begin by reading the Martha's True Stories Buddies Program: Overview.
