Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...

A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

Properties of water make it essential for the life of marine species. Learners complete an online game to answer questions about the role water fulfills for organisms in ocean habitats. The game emphasizes the properties of water and how...

There's nothing better than a cool breeze blowing in from the ocean. Scholars explore how water affects change in temperature using a hands-on experiment on climate. They use measurement tools to compare the continental and oceanic...

Students work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.

Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.

Why are the properties of the water important when exploring the ocean? Young scientists discover the tools and technology used in deep sea exploration in the fourth installment in a five-part series. Groups work together to...

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...

Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

One of the key objectives of Europe's Copernicus Earth program is to monitor the temperatures of the oceans and seas on Earth. Young scholars learn the effects of different heat capacities through two experiments. These experiments...

Water is vital for survival, but how does it help global cultures flourish? Elementary and middle schoolers learn about the different cultures around the world that celebrate water and incorporate it into their festivals or traditions.

Follow the path to the sea floor. Pupils play an online interactive board game to reach the bottom of the sea. Participants must match descriptions of creatures to a property of water dealing with oxygen, food, light, or density to move...

There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...

Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Play Jeopardy as you review what might possibly be an entire year's high school biology course! The vast variety of questions requires that you read through the slides to make sure that they all relate to your curriculum. You could make...

Eggshells and seashells have a lot in common. Learners use the similarities to conduct an experiment that models the effect of ocean acidification on marine animals. Using varying levels of acidic liquids, pupils make observations on the...

As an anticipatory set, young environmental technicians watch a video about how ocean temperatures seem to be changing along with the global climate. They perform a laboratory demonstration with the purpose of observing what happens to...

Students compare and contrast the properties of salt water in the oceans/seas and freshwater elsewhere on the planet. They also analyze mixing caused by currents in the ocean, including the effects of warm and cold water as well as with...

Students explore "matter." In this literacy and three states of matter instructional activity, students listen to Bartholomew and the Oobleck by Dr. Seuss, then work in groups to explore "oobleck" (cornstarch and water mixture) with...

An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

Students investigate the ocean environment. In this ocean lesson, students discover the physical properties of the ocean. Over two days, students work in small groups investigating ocean maps and creating water currents.
