1 hour (or 30 minutes on two different days) adhered to by 5 minutes daily for 2 weeks
Students will compare and also contrast corn and soybean plants, the growth and development, and also how every are provided for various purposes and also make different commodities that every one of us usage daily. Students will additionally learn and also identify the components of a monocot and dicot and measure growth.
You are watching: Is corn a monocot or dicot

Vocabulary (with definitions)Germination- procedure of a plant emerging from a seed and also beginning to grow Embryo- part of a seed that establishes into a plant Cotyledon- component of the embryo within a seed that offers nutrients for the germinating plant Monocot- flower plant v an embryo that has one cotyledon Dicot- flowering plant with an embryo that has actually two cotyledons Ethanol- renewable fuel make from various plant products Biodiesel- renewable fuel made from oils and fats of herbal origin Renewable resource-any natural resource that deserve to replenish itself normally over time Non-renewable resource- any natural resource that cannot be replenishes naturally; once it is gone it is unable to do forever
Interest strategy or Motivator:
Split students right into two groups. Give one team a bucket the soybeans and also one group a bucket of corn, half-full. Offer the groups 5 minute to recognize what they know about the commodity in their bucket. Then, have the soybean group teach the corn group what they think castle know, and also the corn group share what they know. Then, have students talk about the crops and include additional info they know.
Background – farming Connections (what would a teacher must know prior to teaching this lesson):
Corn and soybeans room Iowa’s #1 and also #2 crops, and Iowa leader the nation in corn production and usually soybean production as well. Corn and also soybeans the are raised in Iowa are provided for a selection of different products, including ethanol to strength cards, corn syrup that’s discovered in candy, fruit snacks, and also some fruit juices, corn starch that is a typical thickener, fed to livestock and also used for food commodities like corn chips and also taco shells.
Soybeans are used for biodiesel to strength trucks and also busses. Soybean oil is the main ingredient in vegetable oil, and also can be processed into soy milk, tofu, and soy protein. Soybeans are also used to feeding livestock.
Corn and soybeans develop really different. Corn is a type of grass, and also soybeans room a legume. Corn is a monocot, and also soybeans are dicots, meaning that corn only has one cotyledon and soybeans have actually two. Cotyledons become the an initial true pipeline of the plant. Soybeans build nodules on your roots that assist fix nitrogen indigenous the atmosphere for the plant to use. Corn go not have actually that ability, and also must count on the floor for the nitrogen that needs.
Procedures (main points, action by action activities, and the complete content to be presented to students)
Activity One:Create a KWL chart for both corn and soybeans listing what college student share.Hand students usage magnifying glasses and their own corn and soybean seed come examine. Re-superstructure observations about what castle see and also make a perform on the plank for the corn and also soybean seed.Open currently softened (pre-soaked) seeds and look and also label the components of a corn and also soybean seed. Label the parts on the empty diagram worksheet.Discuss the distinctions in the seeds v the students. What various other crops can have seeds similar to corn? Soybeans? Hand each college student a jewelry size bag, 9 Jelly BeadZ, 2 corn kernels and also two soybean seeds, and a piece of yarn.Students will certainly plant the seed in their bags and also wear around their neck as a necklace every day. In ~ the finish of the day, collect and also place beside a warmth area in the room.
Activity 2Together review each publication by Raymond Bial. Comment on as the books are read assets we obtain from corn and also soybeans. Students might stay more engaged if only particular pages space read fairly than the entirety book. Discuss what provides corn and soybeans a renewable source and exactly how we can use them because that fuel.Complete a big Venn diagram comparing and also contrasting corn and also soybeans as a whole class. The Venn Diagram can compare and contrast uses, growth, and also seed parts. Students will certainly then individually create 3 truth they learned around corn and 3 facts they learned around soybeans on sticky notes and also place them on the “L” part of the KWL chart.Spend 5-10 minute every work or every various other day observing the particle germination necklaces v students. Students can record observations individually or together a class, and include anything they observe to the class Venn diagram.
Essential papers (maps, charts, pictures, or documents)
Extension activities (how can students extend learning external of the classroom? This can include assignments castle do exterior of class.)Students will measure the elevation of your corn and also soybean plant each day because that 2 weeks and also make a twin line graph showing readjust over time. Existing students with a variety of assets containing soybeans, corn, or both. Have actually students work-related in groups to sort the assets into categories the contain corn, soybeans, or both.
