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...

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

This particular lesson was written by the National Earth Science Teachers Association, but density is a concept that you can teach at the beginning of the school year in your life, physical, or earth science classes. It would be fun to...

Using your senses, apprehend the effects of contaminants in water. With a global focus, young scientists conduct a safe experiment by tasting sugar and salt water with different dilutions. After reviewing threshold limits, learners write...

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

There are five types of frost: ground frost, air frost, hoar frost, glaze, and rime. Scholars mix ice and salt in a metal container to observe frost forming on the outside of the can. Animations and videos enhance the learning. 

Students explore water and determine whether or not it is safe to drink. In this water exploration lesson, students are split into groups, to acts as the polluter, taster, and recorder. Students explore by placing different amounts of...

Learners follow this recipe for fun clay creations. In this early childhood art and science instructional activity, students develop creative-thinking skills, fine-motor skills, and sensory awareness while they make, mold, and decorate...

Explore the range of pH using an assortment of household liquids. Scholars create their own pH indicators from cabbage and determine the pH of several liquids. To further their exploration, individuals use the same liquids to create...

Students create a model of a salt marsh to discover the impact of pollution and human activities on water-based habitats including bays and the ocean. They recognize the relationship between natural and developed areas. Students impact...

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 discuss the definitions of physical and chemical properties and changes. They vaporize a solution of salt and water, observing the sodium chloride that is left behind.

Students build a salt dough volcano. They the salt dough using the following ingredients: flour, salt, and water. Students mix flour and salt in a container and add water and mix until the dough is smooth. They then make the volcano....

Van Gogh's Starry Night and Thomas Cole's The Oxbow are featured in a watercolor lesson that encourages young artists to explore various techniques before creating their own landscape.

Students predict, experiment, and draw conclusions about the safety of drinking water. In this ecology lesson, students participate in an experiment to determine if they can taste or see contamination in drinking water. Data is collected...

Students examine the effects of salt on ice. In this salt lesson, students observe what happens to the temperature of ice when salt is added, then make ice cream to see how this knowledge can be used.

Students investigate the need for filtered water. In this filtered water instructional activity, students explore the health hazards posed from consuming unfiltered water. Students construct a water filtration device.

Students see if they can tell if our water is safe to drink by looking at it and tasting it. They perform an experiment using salt and vinegar to see when they can tell water has been contaminated.

Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

Students solve word problems and determine quotients of fractions and mixed numbers. They practice multiplying fractions by increasing a recipe found on a food website. In addition, they increase the numbers to feed the whole class a...

Students explore matter by conducting an in class demonstration. In this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't dissolve...

Students grow salt crystals by making a saturated solution of table salt and let the solution sit around and evaporate.

Students study the habitat of the terrapin. In this terrapin lesson, students create a diorama of the habitat of the terrapin. Students also simulate how it would look if people moved into the area and how predators can threaten terrapin...

Middle schoolers investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.
