This lesson focuses on selenium deficiency in cattle and ways to treat or prevent the deficiency. This lesson is a component of the UCCI Chemistry and Agriscience course Unit 5.
This lesson highlights the types of tillage methods commonly employed in agriculture and draws a correlation between the type of method and the physical properties of the soil.
This lesson introduces the environmental impacts on irrigation. This is lesson 2 or 4 as a part of a larger project.
In the first lesson of this project, students identified tillage systems and their effects on soil. This second lesson in the sequence identifies the role of cation exchange in soil fertility and examine the relationship between soil structure and cation exchange capacity.
This final lesson in a sequence of lessons about tillage, agricultural practices and soil chemistry will combine all of the unit's content into a cohesive presentation that will prepare them for their summative course assessment. Course project soil data will serve as the foundation for the presentation.
This lesson introduces to students four types of irrigation methods used in agriculture. This is lesson 1 or 4 as a part of a larger project.
This lesson is the third in a sequence that focuses on the relationship between tillage, soil structure, nutrient retention and production systems.
This is lesson 4 of 4. Students will be presenting and evaluating their apps for cell phones that will provide farmers with the opportunity to learn how different irrigation methods work depending on soil type.
This lesson serves as the culminating lesson for this project. Students will be compiling their knowledge of aquifers to create a TED Talk about what type of aquifer is the most effective in filtering groundwater. Lesson 4 of 4.
Students will observe contaminated water and build a water molecule.
This is lesson 3 of 4. Students will be creating an app for cell phones that will provide farmers with the opportunity to learn how different irrigation methods work depending on soil type.
Students will do in depth testing of water samples collected from within their community.
Students will understand and demonstrate polarity. Polarity refers to the unequal sharing of electrons within a molecule.
Taking what students know about physical and chemical properties of soil students will devise a plan to increase the fertility of a soil sample.
This lesson allows students to put the aquifers they built in the second lesson of this project to the test. Students will preform a titration on the water collected from their aquifer. Lesson 3 of 4
