Eighth graders distinguish between physical and chemical change. In this chemistry lesson plan, 8th graders observe a series of demonstrations showing physical and chemical changes. They identify the signs that a chemical reaction took...

Learners calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.

Students conduct a series of activity that demonstrates Charles' and Boyle's Law. For this chemistry lesson, students determine the relationship among pressure, volume and temperature. They solve problems using mathematical equation.

Students determine the average mass of a new element using masses from three isotopes. In this chemistry instructional activity, students explain what an isotope is. They discuss their importance and uses.

Students simulate how scientists studied things they can't see like atoms. In this chemistry lesson, students predict what is inside the numbered obsertainers. They design a way to investigate what's inside without opening it.

Students study the process for diffusion of molecules. In this chemistry lesson, students understand molecular movement, develop skills for a chemistry investigation, develop skills in making hypotheses, develop observational skills, and...

Students explain how to make solutions with specific concentration. For this chemistry lesson, students differentiate acids and bases. They calculate molarity of solutions.

Students define what a redox reaction is. In this chemistry lesson plan, students electroplate some wires in the lab. They research the application of electroplating in the real world.

Students write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.

In this chemistry worksheet, students engage in a series of chemical problems that are associated with comparing mass to mass. The answers are included.

Learners explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.

Students predict the product of chemical reaction using the solubility rules. In this chemistry lesson, students balance ionic equation. They perform a lab to check if their predicted products are correct.

Eighth graders identify the three main types of chemical bonds. In this chemistry instructional activity, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.

Students identify the different states of matter. In this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.

Students compare and contrast the properties of substances and mixtures. For this chemistry lesson, students simulate spontaneous mixing by performing a short class activity. They differentiate heterogeneous and homogeneous mixtures.

Students conduct a series of experiments to observe factors that impact molecular movement. In this molecular chemistry lesson, students drop food coloring in water with different properties (hot, with ice, with alcohol) and observe how...

In this atom worksheet, students read about the history of the discovery of the atom. Students write a story, poem, song or other creative project in which they shrink to an incredibly small size and are trapped in a carbon atom.

In this alkanes and conformation worksheet, students name 10 different alkanes, they write the structural formulas for 4 alkanes, and they write Newman projections for 2-methylbutane. They also write structure of stable conformations for...

Students create three-dimensional cell models. They may choose to make either a plant or animal cell but must use a Ziploc bag as the cell membrane, slime for the cytoplasm, and strawberry baskets for the cell wall if making a plant...

In this chemistry worksheet, students use the combined gas law to complete 9 short answer questions in which they calculate new volumes, .original pressures, and change in temperatures.

In this chemistry worksheet, students identify 12 compounds based on their chemical formulas and write chemical formulas for 12 additional compounds.

Learners test the pH of everyday substances. In this chemistry lesson, students test the pH of household substances using litmus paper to classify substances as acids or bases, then use pH to test the validity of the claim that dock...
