In this salinity activity, learners simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.

In this solubility worksheet, students conduct an experiment to see how temperature effects the solubility of salt in water. Students record their data in a chart and then graph the results. Then students complete 2 short answer questions.

Young scholars will make a lava lamp. In this density lesson, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

Sixth graders experiment to understand the ocean's currents.  In this ocean current lesson, 6th graders complete an experiment with two bottles of water and an index card to discover information about the ocean current. ...

Students build a hydrometer to measure the densities of fresh and salt water samples. They record the water temperature and density and use the temperature, density, and salinity conversion graph to locate the salinity. Finally,...

In this chemical reactions worksheet, students review the solubility rules for common salts. Students determine the molecular equation, ionic equation, and net ionic equation for specific reactions. Students calculate moles and volume...

Students investigate the concept of elements and atoms. They conduct research using a variety of resources and use the information in order to create a class presentation. The instructional activity includes specific dialogue and steps...

Eighth graders examine what materials cause water hardness and the relative measure of water hardness in a two part lab activity. In part one, 8th graders add an assigned soap test solution to eleven different test tube solutions in...

A classic investigation on the density of liquids is explained for you in this lesson plan. Te begin, you prepare water samples of different salinities and then add different food coloring to keep them separated and easily identified....

Third and fourth graders engage with a worksheet designed to help them differentiate between melting and dissolving. After reading an informative paragraph about the two actions, they consider four scenarios, and choose whether they...

In this reading comprehension learning exercise, students read an article on "The Chesapeake Bay". Students read 5 sentences and fill in each blank in each sentence with a word from the article. Students answer 3 short answer...

Students aim to explain the need for standardization of units of measurement. They pose their own standards for the value of a kilogram and compare them with the currently used standard.

Students make salt dough and then fashion it into the shape of a lady bug, shich they later paint after it has been baked.

In this ocean water worksheet, students complete a simulation involving salt, water, string, and more to simulate what happens to salt when the salt water evaporates. Students also answer 4 questions.

Students make something that will last forever. In this art lesson, students make a handprint out of clay.

How can you turn an ice cream activity into a scientific investigation? It's easy if you know ionic compounds, heat transfer, and the exothermic and endothermic process. Learners will explore the science behind freezing, insulation, and...

What's all the buzz about electricity? Scholars take part in a scientific activity to test the conductivity of liquids and solutions. They first see if water, salad oil, alcohol, and vinegar cause a buzzer to buzz when electrodes are...

Students conduct an experiment to show how water gets contaminated through neighborhood runoffs.

Turn your class loose to experiment with the different fat content in skim milk, whole milk, half and half, and heavy cream. This is a visually vibrant experiment, as learners drip food coloring on the surface of the products and measure...

Students conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...

Fifth graders use the computer lab to search for answers to questions on their workshet. They discuss the creation of igneouss rocks and listen as the teacher lectures about lava. Students follow directions to mix a batch of salt dough...

Students explore human anatomy by conducting a human senses experiment. In this taste instructional activity, students identify the main purpose of a tongue and how it enhances our eating habits. Students utilize baking coca, lemon...

Students make ice cream while experimenting with the freezing point of water. They experiment with different amounts of salt.

Middle schoolers examine acceptable levels of toxins in swimming areas. Working in groups of four, students dilute a salt or sugar solution to 1 part per 1,000,000 (ppm) solution. Middle schoolers taste test their diluted liquids and...
