In an electrolytic cell, electrical energy is converted into chemical energy, the exact opposite of a battery! Lesson 15 in a series of 36 explores electrochemistry. Participants begin by reading and discussing oxidation/reduction...

What did one titration say to the other titration? We should meet at the end point! Young chemists perform four experiments: dilute solution, neutralization, titration, and figuring pH/pOH. 

In this electrolytes instructional activity, students calculate percent composition, determine the electrical conduction of electrolytes, and explain the Tyndall effect. This instructional activity has 7 problems to solve.

Introduce emerging engineers to the process of metal plating. This resource provides background reading on chemical engineering, plating, and corrosion. It concludes with a copper plating activity. The standards alignment list includes...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

In this conductivity worksheet, learners answer post lab questions about substances that transferred electrons resulting in electricity flowing through the conductivity leads use to test each substance.

Students observe an electrolytic titration using a conductivity tester. In this titration lesson, students observe a solution of acid conducting electricity using the conductivity apparatus. They observe the acid solution being titrated...

Students build conductivity testers and investigate which solids and solutions conduct electricity. Working in groups, they predict which items will conduct electricity and record their answers on worksheets.

There are only six short answer questions on this assignment. Chemists explain electrical conduction properties of salt, salt water, and gold. They compare ionic and covalent bonds. The explain bond strengths. Perhaps you could use this...

Here is a different approach to solutions: a worksheet that has chemistry learners use words to describe them! This is an outstanding exercise that will stretch learners to show what they know. They answer questions comparing solutions,...

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

Buoys around our coastlines are equipped with sensory devices which monitor temperature, salinity, and water pressure. Emerging earth scientists examine some of this data and relate salinity to the electrical conductivity of the surface...

In this acids and bases worksheet, students conduct an experiment to determine if solutions are electrolytic or nonelectrolytic. After completing the experiment, students answer 1 short answer question.

In the last portion of the six-part unit, teams perform an experiment with gold nanoparticles to determine which sport drink has the most electrolytes. The nanoparticles are used as chemical sensors and fluoresce in different wavelengths...

Students encounter the complexity of identifying the cause of unusual variations in WOW conductivity data. They propose theories on why there was a sudden increase in conductivity in Ice Lake, Minnesota during July of 1998.

What a clever idea! Chemistry learners imagine themselves deserted on an island with a radio, but no batteries. They also have a few odds and ends in their pockets and storage chest. They are challenged to create a battery that will...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

Young scholars build their own two-cell battery and determine which electrolyte solution is best suited for making a battery. They discuss background information for their experiment, construct and test their battery, and using the...

Why do metals rust differently? Scholars experiment with metal combinations in a hands-on activity. They create unique environments with different metals and compare the rate and amount of rust for each.

Unleash the power of ... blackberries! Science superstars create solar cells using the juice of berries or leaves of a citrus tree in an engaging lab. In addition to offering a plethora of resources, the teacher's guide gives background...

Compare the drift speed of conduction electrons in a current-carrying wire to the signal speed of changes in current. They also distinguish between DC and AC and describe how AC is converted to DC.

In this chemical equilibrium worksheet, students review hydration, dissociation, and colligative properties. Students also review Le Chatelier's principle. This worksheet has 15 short answer questions and 12 problems to solve.

Fifth graders construct a voltaic battery. They change chemical energy into electrical energy by inserting copper wire into a lemon. They discover the tingle of the wire on their tongue is due to the movement of electrons.
