Eighth graders explore chemical reactions and their products. They define a chemical reaction and describe the characteristics of a chemical reaction. Students classify chemical reactions.

Learners study the difference between chemical and physical weathering. They explore the effects of climate on the weathering process.

Students compare the weathering of materials. in this weathering lesson, students experiment with the chemical and physical weathering of different materials. Students use salt and water as an example of how weathering occurs.

Eighth graders study the conservation of matter.  In this chemical reaction lesson students examine what happens during a chemical reaction and complete a lab activity. 

Students identify patterns and relationships from data that is collected and solve variables.  In this investigative lesson students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.

Students compare the weathering of different-sized materials. Comparisons are made and data analyzed to reach conclusions about the process of weathering. Applications can be made for the higher grades.

In this chemistry worksheet, high schoolers find the words that are related to atoms and molecules. The answers are found by clicking the link at the bottom of the page.

Students observe what occurs as baking soda is heated. They explain why a chemical rather than a physical change occurred during the procedure. Pupils identify the tpe of reaction (decomposition). Students conduct a glowing splint...

Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...

Students work with a partner to determine the identity of an unknown element based on given descriptions. Groups use classroom textbooks, encyclopedias, and science internet sites to identify their unknown element then write a report as...

Tenth graders evaluate the physical mechanisms that cause a change in NOx emissions. In this combustion lesson, 10th graders participate in a research project. Students create a presentation of their findings. 

Students complete a unit on the chemical and technological processes of food preparation. They observe various experiments, describe changes in materials through cooking, identify safety and hygiene issues, and cook various recipes.

Students investigate chemical energy. In this physical science lesson, students blow on saltine crackers to demonstrate how chemical energy in food can be converted to motion. Students compare the saltine cracker experiment to how...

Learners work in pairs to complete a worksheet that asks them to balance several chemical equations. They partner with other students to correct the equations and then follow online instructions to create a table in Word.

Young scholars study the flow of water in the environment.  In this water cycle instructional activity students evaluate the consequences of changes in the water cycle using data. 

In this earth science worksheet, 7th graders classify rock samples according to chart provided and physical properties of the rocks. They answer 2 analysis questions and formulate a conclusion.

Learners consider the adaptation of life forms through natural selection to fill various niches and accommodate changing environmental conditions. They select an ecosystem and conduct research to provide as much detailed information as...

Looking at evolution in detail, this thorough worksheet has complex questions requiring details and explanations of natural selection and diversity. Various examples of biological characteristics are available, and students choose the...

Students identify he phases of matter (solid, liquid, gas), and why they take place. They comprehend what a physical change is and what a chemical change is. Students know the difference between a Mixture and a Solution.

High schoolers discover how temperature effects the solubility of solutes by experimenting with a range of temperatures. They develop skills for observing, inferring, measuring, comparing and contrasting.

In this balancing chemical reactions learning exercise, students balance equations, identify electrons gained or lost in atoms and identify the number of atoms of each element for the reactants and products in equations. They also answer...

Young scholars examine the definitions of biomas gasification and generate their own biomass gas.  In this renewable energy lesson students collect gases and roast a marshmallow. 

Students explore motions, forces and magnetism. They investigate magnetism as a force and examine the construction of a magnet. Students examine the force that magnetism produces.

Students identify the effect of light on objects. In this scientific inquiry lesson plan, students use a chart to write a hypothesis about what will happen when colored construction paper is left in sunlight. Students observe and discuss...
