Curated OER
Ecology - Ecosystem
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.
Curated OER
Sound and Hearing - Internet Research
Pupils 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.
Curated OER
Circuits and Conductors
Young scholars participate in an online instructional activity to explain the conductivity of different materials and the effect of changing the power source.
Curated OER
Gases Around Us
Students participate in an online lesson 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 differ from solids.
Curated OER
Changing State
Students participate in an online lesson to investigate the effects of cooling and heating on water.
Curated OER
Changing Sounds
Students identify how the pitch and the loudness of an instrument can be altered by examining the sounds made by three instruments.
Curated OER
Micro-organisms
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.
Curated OER
Forces in Action
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...
Curated OER
How We See Things
Students explain that mirrors reflect light. They examine how when a beam of light is reflected from a surface, its direction changes.
Curated OER
Changing Circuits
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.
Curated OER
Keeping Warm
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...
Curated OER
Moving and Growing
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. ...
Curated OER
Keeping Healthy
Students 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...
Curated OER
Grouping and Changing Materials
Students 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 could...
Curated OER
Using electricity
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...
Curated OER
Changing Sounds
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.
Curated OER
Gases Around Us
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...
Curated OER
Circuits And Conductors
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.
Curated OER
The Lepidoptera Project
Students are introduced to Scientific Inquiry and discover how to design an experiment that answers critical questions using butterflies as the topic. They design experiments that compare the number of species of butterflies in a vacant,...
Curated OER
Earth's Recyclers
Learners work together in groups to report on different topics related to decomposition. They answer questions and share their answers with the class. They discuss any topic that is unclear.
Curated OER
Can You Beat Jet Lag?
Learners examine the health condition of jet lag. Using mealworms, they test the effect of light on the development of them into adults. They answer discussion questions and examine the relationship of age and one's activity level.
Curated OER
Ecology Vocabulary
In this ecology worksheet, learners read the vocabulary words and then categorize a species found in a field, meadow, or fencerow in their state or region. Students complete 6 problems.
Curated OER
Water and the Earth
In this water and Earth learning exercise, students read a 2 page article on water and the Earth, name the clouds in 2 pictures and then list 4 sources of water in nature.
Curated OER
Bluebirds Ecology Vocabulary Exercise
In this bluebirds learning exercise, students categorize bluebird species found in their state and define vocabulary related to it. Students complete 6 vocabulary words.
