This resource supports English language development for English language learners. In “Earth Day Celebrations” - a brief Listen and Read nonfiction story - students learn how children in New York City, Costa Rica, South Korea, and Russia celebrate Earth Day, a holiday that honors our natural environment. The reading activity includes text, images, and audio, so students can read along while listening to a narrator. At the end of the story, a Sound It Out section lets students listen to these vocabulary words a second time: "parade," "trees," "drums," and "recycling."
This resource supports English language development for English language learners. This online activity follows a young slave's escape from a Kentucky plantation. At each of the four "stops" on this journey, students can listen to audio support of the reading, read primary source quotes, listen to an audio slideshow of primary source images, and write about what they've learned. The teacher's guide provides background information, a Words to Know list, discussion questions, and extension activities.
In this video, students learn that, through adaptation, organisms develop certain features that aid their survival. They pass these on to future generations through the process of natural selection.
In this video, students learn that there are two main types of aquatic ecosystems: freshwater and saltwater. The main difference between these two ecosystems is saltiness. Oceans, rivers, swamps, bogs and streams are all aquatic ecosystems.
In this video, students learn that ecosystems are constantly going through gradual changes. Sometimes those changes are natural, and sometimes they are caused by humans.
In this video, students learn that earthquakes are caused by geologic movement in the earth's crust. They occur in faults, or cracks, located on the Earth's surface.
In this video, students learn each ecosystem is made up of living and non-living things that interact and depend on each other for life. Students learn about producers, consumers and decomposers.
In this video, students learn that the Earth is divided into major kinds of large ecosystems, or biomes. The major difference between biomes in the climate. Several common biomes are explored that include grasslands and forests.
In this video, students learn that a food chain is made up of three groups producers, consumers, and decomposers who interact with each other in an ecosystem to get the energy they need.
In this video, students learn that food webs show all the relationships between all of the plants and animals in a community. How different food chains interact with one another and overlap is also explored.
In this video, students learn that limiting factors control the growth of a population in a certain population. Those factors can be living like predators, or non-living, like sunlight and rain. If these factors change, it can have a big effect on plant and animal populations. Inferences can be made about the relationships between plants and animals.
In this slideshow, magnetism is explored. The resource illustrates the idea that magnetism is the property of attracting iron and a magnetic object's magnetic force is how strong that attraction is. Magnetic fields are the areas where the magnetic force will work. Magnets also have opposite poles, negative and positive and opposites do attract.
In this slideshow, students learn that millions of years of heat and pressure turned the fossils of dead plants and animals into deposits of fuel, such as oil, natural gas, and coal. Fossil fuels are a non-renewable resource, and they create pollution, so it is important to conserve them.
In this video, students learn that heat is a form of energy. Heat is thermal energy that exists in matter. The faster an object's particles move, the more heat it has. Heat can be added to an object by making its particles speed up.
