In this chemical detectives worksheet, students perform six tests on various unknown solutions, including a test for chloride ions, sulphate ions, carbonate ions, iron (III) ions, iron (II) ions, and copper (II) ions. Students record...

Do animals breathe faster when given more oxygen or more carbon dioxide? Young scientists observe the respiration rates of locusts under a variety of gas concentrations to answer that very question. They collect data, analyze the...

In this qualitative analysis worksheet, students read about all the different tests that can be done in chemistry to give qualitative results. Tests include flame tests, forming precipitates with sodium hydroxide, using sodium hydroxide...

In this chemical reactions learning exercise, students write chemical equations and calculate the moles of each product. This learning exercise has 4 word problems.

In this proteins worksheet, students compare the coagulation of egg whites and milk proteins and then complete 5 short answer questions. A protein coagulation quiz is also included with 5 multiple choice questions.

In this redox reaction worksheet, high schoolers perform a redox titration to determine the number of iodide ions that react with each mole of iodate (V) ions in a solution. They calculate their answer using a given equation.

In this solutions learning exercise, students review the properties of solutions, the polarity of molecules, molarity, and solubility curves. This learning exercise has 8 short answer questions and 15 problems to solve.

In this transition metal ions and redox learning exercise, students read about the formation of metal ions through oxidation and reduction.

In this chemical reaction worksheet, students determine the rate of consumption or rate of production for given reactions. This worksheet has 14 problems to solve.

In this chemical equations worksheet, students are given the trends for the reactions between the alkaline earth metals with water, the solubility of the Group II hydroxides and the solubility of the Group II sulphates.

Learners identify the difference between some physical and chemical properties and compare some physical and chemical changes. They design an experiment to distinguish between a physical or a chemical property of their choice.

Young scholars conduct an experiment to test the reactivity of metals and non-metals. In this chemistry activity students test metals with different chemicals to observe the reaction. The results are used to categorize the metals.

Students test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH of the...

High schoolers examine the work of scientists and determine how they test their theories.
