What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Host an exciting lab in which learners burn fruit rinds to better understand hydrocarbons. A reading passage and analysis questions wrap up the lesson. 

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

In this experiment, you will study the reaction between your cobalt complex and the nitrite ion. The nitrite ion can exchange with a water ligand and the mechanism of this ligand exchange will be investigated. Requires Java plug-in.

In this experiment, you will complete the study of the mechanism of ligand exchange. The reaction will be followed colorimetrically and the rates of exchange and ligand isomerization will be measured. Requires Java plug-in.

In this experiment, you will examine the acidity of your coordination complex's water ligand. You will determine the acid dissociation constant of the complex by titrating it with a base. There are eight weeks of experiments in this series.

In this experiment, you will concentrate on understanding the chemistry of ion exchange and estimate the capacity of an ion exchange column from your observations.

In this activity, students' will use a pH sensor to record pH versus time data as an antacid tablet neutralizes acid in lemon juice. They will model the pH data with a modified exponential function.

To get to the top of the mountain before winter arrives, students must derive an equation that relates the necessary amount of hemoglobin to the partial pressure of oxygen at the current and next camp.

In this experiment, you will explore the behavior of the monoprotic acid (acetic acid) and the polyprotic acid (phosphoric acid). By titrating, you will examine the acid and conjugate base species present across the pH scale and the...

In this experiment, you will determine the rate law and confirm the mechanism of the reaction between cyclohexanone and iodine. Requires Java and QuickTime plug-ins to access some features.

This lab further analyzes the results of the experiments carried out in Chemical Kinetics 1. In addition, you will carry out experiments to determine the temperature dependence of the reaction rate constant. Requires Java plug-in.

In the first part of this lab, you will measure the absorption spectra of two conjugated dyes and compare the results to the theoretical predictions of a particle-in-a-box model. In the second part of the experiment, you will identify...

The objective of this science fair project is to determine the correct ratio of baking soda to vinegar that will result in the highest launch of a plastic film canister. The Science Buddies project ideas are set up consistently beginning...

Hold onto your hats. In this science fair project, you will make a device that sends a film canister across the room with a small chemical explosion. The energy for the explosion is derived from the combustion of ethanol. You will...

Students examine actual radioactive decay data collected in an honors chemistry class to find an equation which best fits the data and allows a person to predict the count after certain periods of time have elapsed. Students review all...
