Ion (Derstand) Bonding through Energy Level Diagrams
Ninth graders investigate ionic bonding through energy level diagrams. In this ion bonding lesson plan, 9th graders observe demonstrations to show energy level diagrams using magnets to represent the subatomic particles. Students fill...
Curated OER
Chemistry in Soil-Plant Relationship
Learners apply the science of chemistry to soil and plant relationships. They define diffusion and indicate for which of these nutrient(s) would you expect diffusion to be the most important for movement to the plant root? Pupils...
Curated OER
Determination of Water Hardness
Students investigate water hardness. For this water hardness lesson plan, students determine the water hardness in 4 samples of water after buffering each. By using titration and an indicator, students can determine the amount of calcium...
Curated OER
Solubility
In this solubility worksheet, students calculate the final concentrations of the ions involved in a chemical mixture. Students calculate the solubility of different compounds. This worksheet has 13 problems to solve.
Curated OER
Diffusion through Membranes
Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...
Curated OER
Acid Rain Experiments
Students define the term acid rain, and the causes of acid rain. They locate regions where acid rain is most affected, and what can students deduce from maps of geology and soils in New York State. Students answer the questions why are...
Curated OER
Solubility of Ionic Substances
In this solubility worksheet, students identify substances as either ionic or molecular, define saturated solution and solubility, and calculate concentration of solutions. This worksheet has 7 short answer, 5 fill in the blank, and 27...
Curated OER
Osmosis and Dialysis
How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use a potato...

An Experiment in Alchemy: Copper to Silver to Gold
How exciting would it be for your chemistry class to produce their own "gold"? This experiment allows pupils to witness the chemical reaction of copper pennies as they react with zinc and sodium hydroxide to produce "gold" tokens. It is...
Chymist
An Experiment in Alchemy: Copper to Silver to Gold
Use chemistry to change pennies into gold coins! The experimental procedure leads learners through the process of changing copper pennies to silver and then to gold. They record the mass of each coin through every step of the experiment.
Curated OER
Formula Units
In this chemistry worksheet, students examine the concepts of mole and molarity in order to apply in the laboratory setting. The sheet includes in depth background information.
Curated OER
Sea Water Freeze
Middle schoolers observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water
NOAA
Ocean Acidification
If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...
Curated OER
Determination of the solubility product of silver(I) chloride
For this chemistry worksheet, students examine the concept of solubility of silver chloride. The sheet has in depth concept and laboratory instructions.
