Students identify the unique parts of the body of skates and their egg cases.

Students gain understanding of structure, characteristics, and basic needs of living things and their role in world, identify parts of skate, observe details of skate's body and skate egg case, and identify unique characteristics of skates.

Fourth graders complete activities to study the sources of energy and forms. In this energy lesson, 4th graders discuss the origin of energy and define it. Students participate in several experiments to further study energy including a...

Students use a website to name and compare external body parts of humans and other animals.

Young scholars use a website to help them recognize that sound is generated in a variety of ways and from different sources. They determine that sounds vary in tone and loudness, and learn there are different ways to describe sound.

Students know that humans and some other animals have bony skeletons inside their body. They know that other animals have skeletons on the outside of their bodies. They explain the role of both kinds of skeletons.

Students participate in an online lesson to reinforce the similarities and differences in plants and animals. They classify living things according to observable characteristics.

Students participate in an online instructional activity showing that gases are formed when liquids evaporate and that when a gas is cooled, it condenses to form a liquid, and gases move and flow more easily than liquids, and how gases...

Learners participate in an online lesson to investigate the effects of cooling and heating on water.

Pupils explain the effect of water, temperature and light on plant growth.

Pupils examine how micro-organisms are living organisms that are often too small to be seen. They explain that micro-organisms may be beneficial or harmful.

Students ask questions that can be investigated scientifically. They determine how to plan a fair test by changing one factor while keeping other factors the same, to use measurements to draw conclusions and use scientific knowledge to...

Students explain that mirrors reflect light. They examine how when a beam of light is reflected from a surface, its direction changes.

Students participate in an online lesson to explain how to make bulbs brighter or dimmer in a series circuit by changing the number or type of components.

Students explore data on some of the landforms in Nebraska to distinguish between porous and nonpremeable soils. The state's groundwater is investigated.

Students explore the Ogallala Aquifer in the state of Nebraska. The signs of pollution found are examined and the data classified.

Students examine data about the rivers, lakes, and reservoirs in the state of Nebraska. An understanding of the political implications of boundaries is developed.

Students examine and research the annual rainfall in Nebraska. They create a map of the annual rainfall in Nebraska and use the map to develop explanations of settlement.

Students analyze the parts of the water cycle through research and experimentation. Particular attention is paid to the processes of evaporation and condensation.

Young scholars construct a model of a well to identify how water is brought to the surface. Signs of pollution are investigated.

Students explore water bodies on the planet Earth and their various uses and qualities. They examine several ways that engineers are working to maintain and conserve water sources and think about their role in water conservation....

Students practice sorting living things into groups using their characteristics. Using pictures of leaves and animals, they sort them based on their color and shape and write the objects characteristics under the picture. They share...

Students place words describing a range from cold to hot on a scale. Using those words, they identify places on Earth which are cold, hot, freezing or boiling. They practice using and reading a thermometer with three different beakers...

Students work with a partner to brainstorm a list of as many human body parts as possible. Using that list, they circle any one of those that are bones. They are shown a model of the human skeleton and practice locating various bones. ...
