Manufacture of Cheese
Students examine the steps and safety procedures in the cheese making process. They make and taste a variety of cheeses comparing their properties.
Curated OER
Alcoholic Fermentation in Yeast
Biology learners investigate the effect of sucrose concentration on yeast alcoholic fermentation. During the lesson,they compare and contrast the processes of cellular respiration and alcoholic fermentation. They design an experiment to...
Curated OER
Measuring the Effects of Gravistimulation on Plants
Students conduct an experiment to determine if a plant's response to gravity is affected by different angles of plant orientation.
Curated OER
Comparing Roots After Rotation of Ninety Degrees
Students conduct an experiment and use different measurements of a single root to illustrate the mechanism of plant movement.
Curated OER
Observing the Growth of a Maize Root
Students conduct an experiment in order to observe the typical downward growth of a maize root. They become familiar with the root's growth patterns to use as a control for comparison in other experiments.
Curated OER
Root Caps and the Effect on Gravity Sensing
Students conduct an experiment to determine how the absence of a root cap affects a plant's ability to sense gravity. They make comparisons between capped and decapped roots.
Curated OER
WATER QUALITY FOR FRESHWATER ORGANISMS
Students use determination of dissolved oxygen and water temperature changes to determine the environmental impact from thermal pollution.
