Science Lesson Plans

Explain why physical changes are reversible, and chemical changes are irreversible.

Identify from pictures and diagrams the parts of the circulatory system as heart, blood, and blood vessels, and describe how they work.

Describe the different ways that plants reproduce, such as pollination, seed production, and plant propagation.

Plan a simple scientific investigation that includes the features of a fair test, replication, and accurate measurement to determine which type of plant propagation, such as cutting, budding, layering, grafting, works best for garden plants.

Describe the differences between animals with a backbone (vertebrates) and animals without backbones (invertebrates) by using common local examples of each group.

Explain the role of heat energy in change of state processes.

Describe changes of state for solids, liquids, and gases as melting, evaporation, freezing, condensation using diagrams and flowcharts.

Explain the benefits of each mixture separation technique in preparing useful products.

Demonstrate various techniques in separating mixtures, such as decantation, winnowing, scooping, picking, evaporation, filtering, sieving, and using magnets.

Describe air as a mixture of oxygen, carbon dioxide, nitrogen, and water vapor.

Describe useful everyday examples of uniform and non-uniform mixtures, such as solutions and suspensions.

Apply the features of a fair test: a. change one factor, b. measure one factor, and c. keep all other factors the same.

Recognize the features of a fair test and that scientific investigations also involve a) doing at least three trials, or use replication, and b) observing, measuring, and recording accurately.
