The Molar Enthalpy of a Neutralization Reaction
Determines the molar enthalpy of neutralization of sodium hydroxide using calorimetry. The experimental value is then compared to the actual value that was determined using Hess’s Law.
-
Succession and Climax Communities
Examines successional events and their causes in various communities and ecosystems. Analyses data on population and community change and examines the impact of human activity on various ecosystems. Presents some new ideas on the concept of succession.
-
Patterns of Population Growth and Management
Explores patterns of population growth and population management strategies. Illustrates the J-shaped growth curve of r-selected populations and the S-shaped growth curve for K-selected populations. Discusses biodiversity and sustainable development.
-
Population Changes, Density and Chaos
Demonstrates how mathematical formulas can be used to analyse population changes. Explains population growth cycles and outlines the factors that affect density. Introduces the chaos theory and how it is used to study population changes.

-
Thermochemical Changes – Resource Correlation Guide – Unit 1
Provides additional information, experiments and problems on concepts presented in the video programs.
-
Embryonic Development and Differentiation
Describes the events that occur once fertilization of the ovum has taken place. Explains the various stages of embryonic development and differentiation using slides and models. Presents theories on various mechanisms that trigger cell differentiation.
-
Fetal Development and Birth
Outlines development during each trimester of pregnancy and the hormones involved in regulating fetal development, birth and lactation. Illustrates the mechanism for exchanging nutrients and wastes between mother and fetus.
-
Cell Cycle, Mitosis and Cytoplasmic Division
Prepared slides, graphics and simulations examine the various stages of mitosis. Explores the changes in cell division during aging and compares a typical cell cycle to that of a cancer cell. Discusses the detection and various treatments for cancer.
