1 hour (or 30 minute on two separate days) adhered to by 5 minutes everyday for 2 weeks


Students will compare and also contrast corn and also soybean plants, the growth and development, and also how every are offered for different purposes and make different products that all of us usage daily. Student will also learn and also identify the components of a monocot and dicot and measure growth.

You are watching: Corn is a monocot or dicot

Interest approach or Motivator:

Split students right into two groups. Offer one group a bucket the soybeans and one team a bucket that corn, half-full. Provide the groups 5 minutes to identify what they know about the commodity in your bucket. Then, have actually the soybean team teach the corn team what castle think they know, and the corn team share what castle know. Then, have students talk about the crops and add additional information they know.

Background – agricultural Connections (what would certainly a teacher have to know prior to teaching this lesson):

Corn and soybeans room Iowa’s #1 and #2 crops, and Iowa leads the nation in corn production and also usually soybean production as well. Corn and also soybeans the are raised in Iowa are offered for a variety of various products, including ethanol to power cards, corn syrup that’s discovered in candy, fruit snacks, and also some fruit juices, corn starch that is a common thickener, fed to livestock and used for food assets like corn chips and taco shells.

Soybeans are supplied for biodiesel to strength trucks and busses. Soybean oil is the main ingredient in vegetable oil, and also can it is in processed right into soy milk, tofu, and soy protein. Soybeans are additionally used to feeding livestock.

Corn and also soybeans develop very different. Corn is a kind of grass, and soybeans space a legume. Corn is a monocot, and also soybeans are dicots, definition that corn only has actually one cotyledon and also soybeans have two. Cotyledons become the very first true leaves of the plant. Soybeans construct nodules on their roots that aid fix nitrogen indigenous the atmosphere for the tree to use. Corn walk not have actually that ability, and also must depend on the floor for the nitrogen that needs.

Procedures (main points, step by step activities, and also the complete content come be presented to students)

Activity One:

Create a KWL chart because that both corn and soybeans listing what students share.Hand students usage magnifying glasses and their own corn and also soybean seed come examine. Re-superstructure observations around what lock see and make a list on the board for the corn and also soybean seed.Open currently softened (pre-soaked) seeds and also look and label the parts of a corn and also soybean seed. Brand the components on the empty diagram worksheet.Discuss the differences in the seeds v the students. What various other crops might have seeds comparable to corn? Soybeans? Hand each college student a jewelry size bag, 9 Jelly BeadZ, two corn kernels and also two soybean seeds, and a item of yarn.Students will plant the seeds in your bags and also wear about their neck together a necklace all day. In ~ the end of the day, collect and also place beside a heat area in the room.

Activity 2

Together read each publication by Raymond Bial. Talk about as the publications are read products we gain from corn and also soybeans. Students may stay an ext engaged if only specific pages are read rather than the totality book. Talk about what provides corn and also soybeans a renewable source and just how we deserve to use them because that fuel.Complete a huge Venn diagram comparing and contrasting corn and also soybeans as a totality class. The Venn Diagram might compare and contrast uses, growth, and also seed parts. Students will then individually compose 3 facts they learned around corn and 3 facts they learned about soybeans on sticky notes and place lock on the “L” portion of the KWL chart.Spend 5-10 minute every work or every other day observing the seed germination necklaces with students. Students have the right to record observations individually or together a class, and include anything they observe to the class Venn diagram.

Essential files (maps, charts, pictures, or documents)

Extension activities (how can students prolong learning exterior of the classroom? This could include assignments castle do outside of class.)

Students will measure the height of your corn and also soybean plant each day because that 2 weeks and also make a dual line graph showing readjust over time. Existing students with a variety of commodities containing soybeans, corn, or both. Have students job-related in teams to kind the assets into categories that contain corn, soybeans, or both.
