Show the six-minute video, "Changing Planet: Fading Corals," and then demonstrate how calcium carbonate forms a precipitate in the presence of carbon dioxide. Separate your scientists into small groups to gather information about coral...

Students become familiar with oceanography terms by writing an oceanography horror story.

Yes, scientists say, there is other life in our solar system! And the best place to look is on Europa, a moon of Jupiter. Here, learners mimic the techniques scientists use to gather information about objects in our solar system, write...

Students are introduced to the idea of soil as a habitat for many different organisms. They are introduced to the links between the biological adaptations of an organism and the physical demands of its habitat. Pupils are introduced to...

Students test tap water for hardness and mineral content. In this environmental science instructional activity, students identify the different stages of the water cycle. They classify plant and animals according to the rules of taxonomy.

Seventh graders describe the main characteristics of warm-blooded vertebrate animals. They compare and contrast the two different groups of warm-blooded vertebrate animals by looking at external, reproductive, and growth characteristics.

With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

The incredibly shrinking meter—decimeters to centimeters, to millimeters, and now to nanometers! Learners may have a difficult time visualizing particles on a nanoscale. Help them see a little clearer using a well-designed lesson...

Space, the Final Frontier. The nine NASA-created challenges in this unit are designed to teach class members the engineering design process. Each challenge comes with teacher and student pages that can be used individually or as a...

Students identify animals in ecosystem depicted on 16th Century ceramic basin and classify them as herbivores, carnivores, or omnivores based on physical characteristics and prior knowledge, determine which life forms in ecosystem are...

Young scholars review the classification system for living organisms and apply it the classification of insects and flowers in the still life by Ambrosius Bosschaert. They create a chart classifying the animals and plants in the painting...

Students explore how oil pollutes the oceans. In this science lesson, students investigate various materials that could be used to clean up an oil spill. Students discuss which materials worked best and how humans can reduce oil spills.

Students are introduced to the concept of acids and bases and arouse curiosity about acids and bases in daily life. They are introduced to the measurement of soil pH. Pupils are introduced to the effect of soil pH on nutrient cycling...

Students explore simple and compound machines. In groups of four students, they design a compound machine using K'NEX that has a stated purpose and consists of at least two simple machines.

In this human body worksheet, students are given clues to find hidden words in boxes. Topics include the human body systems, the components of living things and the building blocks of life.

Students examine the factors the affect water quality, and allow for animals and plants to live. They look at how engineers apply water quality information when making stream modifications in order to ensure drinking water quality. They...

Learners are introduced to the water cycle and water movement in soil. For this water cycle lesson, students explore how water moves through the water cycle and discuss water sources, natural reservoirs, soil...

Students identify a diversity of issues related to aquatic organisms and habitats and develop their own opinions concerning some issues involving aquatic life and habitats. They investigate, write and produce a newspaper that features...

Lead your young scientists into an exciting world as they participate in a role play and experiment focused on proteins and DNA. After researching the Central Dogma of Biology, individuals or groups participate in a classroom...

Give pupils a magnifier, a mirror, and a flashlight so that they can examine their own pupils. As they shine a light on their eyes, the light is shone on how this structure dilates and contracts to control how much is allowed into the...

Pupils explore diagrammatic and taxonomic keys and their application in the marine sciences. They sort and classify objects and organisms based on visual attributes.

Students use a simple method to collect living microorganisms from natural and/or artificial environments and develop skills in microscopy, observation, drawing, speculation, hypothesizing, oral presentation, and raising questions.

Students make sets of nautical signal flags and use them to communicate in the classroom.

Learners design and execute a lab through which they study the distinctions between density, buoyancy, and volume.
