Learners use examples of Joseph Raffael's art of nature to create an all-school mosaic of a tree in spring using clay.

Learners, using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, observe and record the role of light in photosynthesis. They consider plant production of carbon dioxide and the use of live materials in biological...

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

Students 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.

Learners participate in an online lesson to explain the conductivity of different materials and the effect of changing the power source.

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...

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

Students identify how the pitch and the loudness of an instrument can be altered by examining the sounds made by three instruments.

Students 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...

Young scholars 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.

Third graders research ecosystems, the work of ecologists, John Muir's contribution to the environment and an endangered species of their choice. They read books, participate in discussions, and write reports.

Learners 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...

Pupils 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. ...

Learners review what the heart does and why the muscles in the body need oxygen. As a class, they measure their pulse rate while they are resting and after they have jogged for three minutes. They are helped by their teacher to convert...

Young scholars feel and observe different types of materials. Using the internet, they sort objects based on the materials they are made from and justify their reasons for putting it in a certain category. They identify objects that...

Students explore how a switch can be used to break a circut. Students construct a simple series circuit and use it for a purpose. Students read the "The Lighthouse Keeper's Lunch,or one of the "Katie Morag" stories which clearly shows...

Students identify how the pitch of an instrument can be altered. They complete a worksheet by labeling several images in order of pitch and then fill a bottle with water to create a sound that matches a pitch on a drawn card.

Students participate in a whole class discussion about solids, liquids, and gases. Students get involved in a teacher-directed experiment related to solids, liquids, and gases. Students complete worksheet, writing the names of the parts...

Students predict the common classroom items, such as paper clips, chalk, keys, or erasers, that will be good conductors in a circuit. They build circuits using a variety of circuit diagrams to test their predictions.

Students explore animal diets and teeth. In this animal science instructional activity, students view photos of animals and their teeth. Students identify the type of diet the animal has based on the teeth. Students are introduced to the...
