Watershed Awareness
Students investigate the relationship between upstream influences in their watershed and the watershed's estuary. They apply the scientific process to test a hypothesis while examining the impact of upland activities on estuaries.
Curated OER
Biodegradable Plastics
Pupils prepare a type of biodegradable plastic. They design method(s) to compare its properties with some common plastics that are readily available in the market. They later advance to identifying variables in an experiment and fair test.
Curated OER
Seeds and Similarities
Students use the scientific inquiry method to identify the changes in a plant's life cycle. In groups, they plant different types of plants and use a chart to compare and contrast their growth rates. They share their conclusions with...
