Students read about how acid/base balance affects a person's health. This activity includes animation.

Students identify the parts of a triple beam balance and practice measuring the mass of objects.

Learners examine the 10 steps of the accounting cycle. The cycle begins with the analysis of source documents and ends with the post-closing trial balance and interpreting the financial information.

Learners read about the purposes of balance sheets and income statements and then place accounts into these two financial statement categories in a drag-and-drop exercise.

Learners read about the most common forms of financial statements including balance sheets, cash flow statements, and profit and loss statements. A brief quiz completes the activity.

Learners listen to an explanation of balance sheet basics for farm operations. They then determine how purchases should be listed in a farm record book and complete sample income and expense sheets.

In this screencast, learners examine hearing and balance. Detailed drawings of the outer, middle, and inner ear structures are included.

Learners examine the main characteristics of the four financial statements required in accounting: the income statement, the owner's equity statement, the balance sheet, and the statement of cash flow.

In this interactive object, learners identify the symptoms of fluid volume excess and fluid volume deficit.

Equilibrium plays a vital role in our lives. We'll show you how the equilibrium formula works in real life using our friend the chicken.

In this animated object, learners examine the structure and function of intracellular and extracellular fluid. They also read about the most common electrolytes in the body and complete a matching exercise to test their knowledge.

In this animated activity, learners examine the terms "half-reaction," "oxidizing agent," and "reducing agent" and follow five interactive examples to balance equations for oxidation-reduction reactions. Three problems are provided as a self-check.

In this interactive object, learners identify charges on ions, write new formulas based on charge, and balance equations using coefficients.

In this interactive object, the learner matches various disorders to the acid-base disturbances they cause.

Learners examine a bank statement and a reconciliation form and study how to balance a checking account.

Learners read about the role of water, the basic physiology of water balance, and the effects of dehydration particularly on elderly clients. Tips for maintaining proper hydration are presented. In an interactive exercise, students calculate how much fluid a client needs based on his/her age, health, and weight.

Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.

Students read and test themselves on the conditions that cause specific acid/base imbalances.

Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.

In this accounting learning object, students follow the steps involved in the closing process. Temporary accounts contain ending balances for a specified period and must be closed.
