Background Agricultural Connections
Interest Approach – Engagement
- Play a game of Pictionary with your students to illustrate the steps of egg production from the farm to their home.
- Print 1 copy of the Egg Interest Approach Pictionary Cards and cut the 6 cards into separate pieces.
- Choose 6 students from your class and line them up at the board in chronological order from left to right.
- Give each student 1 card and instruct them to sketch their word until the class guesses it. Begin with student #1 and continue until all 6 students draw their word.
- After the class guesses each word, have the student read the additional facts on their card.
- When the game is complete, the Pictionary sketches will illustrate the path of egg production from the farm to our homes.
Activity 1: Egg-ceptional Eggs
Scientific Inquiry: Egg Facts
- Read Egg-ceptional Eggs and complete the Doodle Bugs.
- Demonstrate how to crack a raw egg: Hold the egg over a plate. Gently tap the side of the egg shell with a table knife to crack the shell. Use both hands to gently pull the two sides of the shell apart. Pour the egg onto the plate. Discard the egg shell and wash your hands.
- Demonstrate how to peel the shell off a boiled egg: Use the dull end of your knife to tap the wider end of the egg shell. Make several small cracks in the egg shell. Use your fingers to peel the shell off the egg white (this can also be done under cool water). Place shell pieces on a paper towel and throw away.
- Instruct your students to read the Scientific Inquiry: Egg Facts directions, study the egg diagram, gather supplies and begin the activity. Remind students to record their findings in the appropriate chart and to record units of measurement, when appropriate.
- Review the use of measuring tapes and scales. Students will place a plate or bowl on the scale, zero the scale and then add their egg, egg white or egg yolk. Zeroing the scale makes the weight of the plate/bowl disappear.
- A teacher or other adult should break one raw egg for each group to study. Be sure to dispose of the egg when the group is done with their observation.
- Review the parts of the egg and what the class learned about each part.
Activity 2: Fantastic Foams
Scientific Inquiry: Peaks, Peaks, Peaks
- Read Fantastic Foams and complete the Doodle Bugs.
- Follow Scientific Inquiry: Peaks, Peaks, Peaks directions to make meringue cookies.
- Demonstrate how to separate egg whites from yolks:
- Place the egg separator over the mixing bowl. (A helper may hold the egg separator.)
- Gently tap the side of the egg shell with a knife to crack the shell.
- Use both hands to gently pull the two sides of the shell apart.
- Pour the egg into the egg separator. The egg white will fall into the bowl and the yolk will stay in the egg separator and be discarded.
- Allow your students to take turns beating the egg whites, adding ingredients and dropping teaspoonfuls of meringue onto cookie sheets.
- While beating the egg whites, ask your students to make observations about visible changes (size, color, state of matter). Be sure to point out soft and stiff peaks.
- Instruct students to complete the Venn diagram.
- While the cookies are baking, complete While You Wait: Egg-citing Egg Foams.
- When the cookies are done, an adult should use oven mitts to remove the cookie sheets from the oven. Place cookie sheets on the hot pad holders.
- Let the cookies cool. Remove the cookies from the tray with a spatula and place on napkins.
- Serve one cookie to each student. Students will answer taste test questions.
While You Wait: Egg-citing Egg Foams
- Instruct your students to make a prediction before you begin beating the egg whites and yolks.
- Allow students to assist with beating the egg whites and yolks and measuring the volume of the foams.
- Instruct students to record times and volumes on their workbook pages.
- Discuss the difference between the egg foams. Remind students that egg whites are mainly protein and yolks contain both protein and fat. The protein makes the egg foams strong. Whereas, fat prevents foaming.
Concept Elaboration and Evaluation
After conducting these activities, review and summarize the following key concepts:
- The eggs we eat are typically produced by chickens on farms.
- It's important to thoroughly cook eggs to decrease the chance of becoming sick from a foodborne illness.
- Eggs are a good source of protein.
Egg Spectrum: Complete the attached math enrichment activity. Students will learn about various colors of egg shells, their nutrients, and perform various calculations using eggs.
Farmer's Market Tour: Arrange a tour of your community's farmers' market in the fall or spring to observe the variety of food items farmers have produced. Assign students to talk with the farmers to learn more about what they do. If a real tour is not possible, have students do a virtual tour online or invite one or more local farmers to talk about their role and the work they do in your community.
Visit the Interactive Map Project website and view the map representing Egg Production in the United States. Identify the state that produces the most eggs, then find where your state ranks for egg production.

Common Core Connections
Speaking and Listening: Anchor Standards
CCSS.ELA-LITERACY.CCRA.SL.1Prepare for and participate effectively in a range of conversations and collaborations with diverse partners, building on others’ ideas and expressing their own clearly and persuasively.
Language: Anchor Standards
CCSS.ELA-LITERACY.CCRA.L.4Determine or clarify the meaning of unknown and multiple-meaning words and phrases by using context clues, analyzing meaningful word parts, and consulting general and specialized reference materials, as appropriate.
CCSS.ELA-LITERACY.CCRA.L.6Acquire and use accurately a range of general academic and domain-specific words and phrases sufficient for reading, writing, speaking, and listening at the college and career readiness level; demonstrate independence in gathering vocabulary knowledge when encountering an unknown term important to comprehension or expression.
Mathematics: Practice Standards
CCSS.MATH.PRACTICE.MP1Make sense of problems and persevere in solving them. Students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Students check their answers to problems using a different method, and they continually ask themselves, “Does this make sense?” They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.
CCSS.MATH.PRACTICE.MP2Reason abstractly and quantitatively. Students make sense of quantities and their relationships in problem situations. They bring two complementary abilities to bear on problems involving quantitative relationships: the ability to decontextualize—to abstract a given situation and represent it symbolically and manipulate the representing symbols as if they have a life of their own, without necessarily attending to their referents—and the ability to contextualize, to pause as needed during the manipulation process in order to probe into the referents for the symbols involved. Quantitative reasoning entails habits of creating a coherent representation of the problem at hand; considering the units involved; attending to the meaning of quantities, not just how to compute them; and knowing and flexibly using different properties of operations and objects.
CCSS.MATH.PRACTICE.MP4Model with mathematics. Students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace. Students who can apply what they know are comfortable making assumptions and approximations to simplify a complicated situation, realizing that these may need revision later. They are able to identify important quantities in a practical situation and map their relationships using such tools as diagrams, two-way tables, graphs, flowcharts and formulas. They can analyze those relationships mathematically to draw conclusions.
CCSS.MATH.PRACTICE.MP5Use appropriate tools strategically. Students consider the available tools when solving a mathematical problem. These tools might include pencil and paper, concrete models, a ruler, a protractor, a calculator, a spreadsheet, a computer algebra system, a statistical package, or dynamic geometry software. Students at various grade levels are able to identify relevant external mathematical resources, such as digital content located on a website, and use them to pose or solve problems. They are able to use technological tools to explore and deepen their understandings of concepts.
