Tenth graders distinguish between acids and bases. In this pH lesson, 10th graders view a PowerPoint and discuss the characteristics of an acid and a base. They investigate natural substances to determine the pH level of each.

First graders investigate the various forms of water. They discuss the properties of water. They discover examples of water's various states and locate other solids, liquids, and gases in their homes.

First graders investigate water properties by participating in a hands on experiment. In this ice formation lesson, 1st graders examine real ice cubes in a bowl and identify the reasons why certain cubes melt faster than others. Students...

In this elements worksheet, students complete a graphic organizer comparing lithium, sodium, and potassium observations. Then, they determine how these elements react with water. Students complete three fill-in-the-blank questions.

Students demonstrate how water quality and environmental health issues can be analyzed together, how hydrologic information can be built up, and how decisions can be made using GIS.

Students explore forms that water can take. In this science lesson, students participate in hands-on activities that require them to change water to a solid and back to a liquid again.

Students complete activities to study the properties of solids and liquids. In this states of matter lesson, students investigate the melting and freezing of a range of materials in a virtual experiment. Students melt the substances and...

In this physical world worksheet, students review concepts relating to the chemical and physical properties of matter, density of matter, and if matter is a solid, liquid, or gas. This worksheet has 9 terms in a word puzzle, 4 true or...

In this states of matter worksheet, students read a 2 page article on the 5 states of matter, answer statements with multiple choice answers, fill in 4 fill in the blank statements and 3 true or false statements about the 5 states of...

Young scholars investigate the two key concepts covered in this instructional activity: first, how pollution can affect plants, and, second, how polluted plants affect the rest of the food cycle. In sum, this instructional activity...

Students explore the three states of matter. In this matter lesson, students are shown a variety of examples and decide whether it is a liquid, solid or gas. Students brainstorm what characteristics the objects in each group share.

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

Students experiment with balloons, soda water and raisins to find out about the states of matter.  In this solids, liquids and gases activity, students complete a group activity with balloons to recognize the state of matter in it....

First graders discuss how water changes from liquid to a gas and back to a liquid as part of a continuous cycle. They conduct an experiment demonstrating that things happen to water to change its properties.

Students become aware of the differences between ocean water and lake water by smelling, tasting and seeing. They distinguish between land and bodies of water on a globe and gain increased awareness of oceans and life.

For this chemistry worksheet, students complete a crossword puzzle by rearranging 13 anagrams about elements. They create their own anagrams from 3 given words.

In this solutions worksheet, learners determine colligative properties, calculate specific heat, and review the kinetic theory as it applies to gases. This worksheet has 8 multiple choice and 9 problems to solve.

Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...

In this moles worksheet, students review solubility, moles of solute, molar mass, and colligative properties. This worksheet has 10multiple choice questions and 11 problems to solve.

Third graders learn the effects of temperature on the states of water. Then students create paper snowflakes. Finally students complete a computer project with software which teaches the different states of water.

Students recognize that air has the properties of mass and volume. They predict, observe, and evaluate the effect of the air on various objects, using bubbles and bubble wands.

Looking for a terrific chemistry lesson for your 5th graders? This one could be for you! After a teacher-led demonstration, learners are broken up into groups and perform an experiment using cabbage juice, water, window cleaner, and...
