Low tides, high tides, spring tides, neap tides, diurnal tides, semidiurnal tides, mixed tides ... just how many types of tides are there? The 10th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO)...

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Caterpillars have an amazing, yet tough job to perform in their short lives — eat much, avoid predators, and try not to let all those comments about being the unattractive stage of the life cycle get to them. How do they handle it all?...

How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in...

Discuss how diseases have impacted human history. Divide your class into groups and assign each group one of the following: tuberculosis, malaria, plague, cholera, smallpox, and AIDS. They read up on, complete a concept map, and present...

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Now that you know the ocean has layers, let's name them. The seventh installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program covers terminology associated with ocean layers, such as thermocline and...

With a couple of neat diagrams on student handouts, your life science or health class will examine the contents and serving sizes of healthy foods. They dissect a slice of pizza and scrutinize the nutritional value of its components in...

You will find a viewer-friendly PowerPoint on the growth rings and other features found in a cross-section of a tree trunk, affectionately known as a "tree cookie." A few worksheets are provided for practice counting tree rings and a...

The first of three pages in this handout provides a brief history of our understanding of the cell. It also differentiates between prokaryotic and eukaryotic cells. The second is a collection of true and false, multiple choice, and short...

Sorting is a very important skill that can be used in math and even science. Learners get familiar with some environmentally friendly vocabulary terms as they practice separating objects that can be recycled from those that can't. They...

How do Earth's changes affect humans? Pupils learn about physical and chemical changes on Earth and how they lead to erosion, earthquakes, and volcanoes. Using the text, they also explore the concepts of electricity and magnetism by...

How do we interact with Earth? Scholars learn about the sun, Earth, moon, forces, gravity, and heat sources by reading a text and performing hands-on demonstrations. They also differentiate between living and non-living things using...

Make life more organized using mathematics. Scholars get a good look at budgeting and personal finance by using linear equations. They research salary information and costs to develop mathematical models, including equations and graphs.

There is a strong correlation between the carbon dioxide concentration in the air temperature. Scholars offer explanations for the correlation in one of four AP® free-response assessment questions. Their analyses in the other questions...

In this life cycle workbook, 3rd graders complete several different activities in which they analyze different invertebrates, identify arthropods, examine human biology and plants, and study natural environments. 20 different activities...

Students explore the topics of ocean water salinity, ocean life zones, marine life classification, and ocean food chains. They observe demonstrations, conduct experiments, complete quizzes and handouts, and analyze key vocabulary.

Students research sea life using laptop computers. In this sea life lesson, students participate in a field trip to the beach and enter observations into their laptop computers. Students classify shells and sea life.

Students identify life processes and create their own creature. In this creative science lesson, students identify an organism's life processes and categorize them into groups. They then create their own creature and write about how it...

Students list salmon life cycle stages in order, list three threats that salmon face throughout their lives, and examine important role native fish play in aquatic food chains throughout their life cycles.

Students participate in a discussion of recent environmental issues affecting their own community or ones nearby. In groups, they research the role of food additives and the purpose of adding them to foods. They also determine their...

Students create their own insect, build a model of it and explain its life cycle.

Tenth graders discuss marine mammal diving reflex, and measure pulse rate while holding their breath under three conditions: control, warm water, and ice water to determine if humans exhibit marine mammal diving reflex.

Students simulate the life cycle of Hawaii's Honu. For this Science lesson, students act out the life cycle of the Hawaiian sea turtle. Students determine and play the roles of prey and predator.
