Background Agricultural Connections
Interest Approach – Engagement
- Hold up a potato for students to see. Ask if they can tell you what it is and what people use it for. (It’s a potato that’s used for food.)
- Make a list on the board of all the different ways students can think of to eat potatoes. Ask how many recipes they think there are for cooking potatoes.
- Do a live Google search for potato recipe and show students how many results there are (millions!).
- Ask students if they can tell you where potatoes come from. Prompt them to discuss that potatoes grow from plants that are cultivated by farmers and gardeners. Explain that they will be learning more about potatoes and where they come from in the following lesson.
Activity 1: Potato Life Science
- Provide each student with 10 copies of the Potato Pattern, and ask them to cut out each one. Explain that they will be using these cutouts to make a journal, and they should color the front and back covers. Ask them to write their names and the title “Potato Journal” on their front covers. Then staple the cutouts together on the top or left side.
- Place one of the large baking potatoes on a paper plate in a location where students can easily make observations.
- Ask students to examine the potato and describe it on the first page of their journals. They should make sure to note the date on which observations are made.
- Ask students if they think the potato is living or nonliving. Discuss the characteristics of living and nonliving things.
- Using the information provided in the Background Agricultural Connections, discuss how potatoes grow with students.
- Explain to students that they will observe the potato to find the number of days that pass before the eyes begin to sprout. The potato contains enough nutrients, energy, and water for the plant to begin to grow without any soil.
- Tell students that they will also observe a potato planted in soil and compare its growth to that of the potato with no soil. Show students the bag of potting soil and ask them if it is living or nonliving. Point out that the soil contains nonliving nutrients that the potato will use as it grows.
- Plant and care for the potato as follows:
- Fill the pot approximately one-quarter full of potting soil. Place the potato on top of the soil and cover with three to four inches of soil or until the pot is about half full.
- Position light to shine on pot.
- Water lightly. Do not over water or the potato may rot. After green sprouts appear, pay attention to the soil moisture and water when dry.
- As shoots appear and get tall, cover them with more soil, and tie them to a stake.
- When flowers start to appear, stop watering to prevent the potatoes from rotting.
- As the potato grows, it may push up the dirt around the stem or even crack the container in which it’s planted.
- After six to eight weeks, when the potato plant has finished flowering or the top starts to die, harvest the potatoes by gently pulling the plant out of the pot.
- Lay the plant on newspaper.
- Have students sift through the dirt to find any potatoes left behind in the pot.
- Instruct students to document their observations of the potatoes in their journals at regular intervals (e.g., once a week).
- As the potatoes grow, or after harvesting the first new potatoes from the potted plant, discuss the differences that students observe between growing a potato with and without soil. Discuss the importance of soil to plants as an example of the interaction between living and nonliving things. Ask students if they can think of any other nonliving things that affect plants (e.g., light, water, temperature).
Activity 2: Potato Geography
- Discuss with students the Background Agricultural Connections information regarding the origin and history of potatoes.
- As you are discussing the origin and history of potatoes, provide each student with a World Map and instruct them to:
- Locate and label Bolivia, Peru, and the Andes Mountains in South America. This is where the potato was first domesticated. A great variety of potatoes is still grown in this region.
- Draw a line connecting South America to Europe. Early explorers brought potatoes to Europe, but it took some time for Europeans to develop a taste for potatoes.
- Draw a line connecting Europe to the United States. After Europeans began growing and eating potatoes, the crop then began to catch on with settlers in North America.
- Locate and label Ireland. From 1845 to 1852 there was mass starvation, disease, and emigration from Ireland due to the failure of potato crops.
- Locate and label China, India, Russia, and the Ukraine. China is now the world’s top potato producer, followed by India, Russia, and Ukraine. The United States is the fifth largest producer of potatoes in the world.
- In the United States, label the approximate location of the states Idaho and Washington. This is the greatest potato-producing region in the United States.
- Potatoes grow best in cool climates with fertile soils. Have students compare the geography of different potato-growing regions of the world.
- Using a relief map, look at the terrain of Bolivia, Peru, and Idaho to see what they have in common. Look at the terrain of China, India, Russia, and Ukraine.
- Compare and contrast these places to find what features they have that would make potatoes an important crop there (e.g., cool climate, mountains). You may wish to use the National Geographic Mapmaker which includes layers for climate and weather.
- Discuss cultural, economic, and social factors that might affect potato production in the different countries. For example, India does not have a cool climate, but there is demand for potatoes, which means farmers can make money by growing them. They grow potatoes in the winter months and plant varieties that are suited to their climate.
Activity 3: Potato Dress Up Contest
- Hold a Great Potato Dress Up Contest! Give each student a potato, access to arts materials, and the following directions:
- Choose a country/time period discussed in the previous activity, such as Ireland in the 1800s, ancient Peru, or modern India.
- Research how people traditionally dressed (or commonly dress) in your chosen area and time period.
- Dress up your potato (without cutting it) in the traditional or common dress of your chosen area and time period. You may dress it in a costume, paint it, add different things to it, etc.
- Think of a name for your potato
- After students have finished dressing up their potatoes, give each student an index card, and ask them to write the following things on it:
- Potato’s name
- Where and when is your potato from?
- Short description (1-3 sentences) of what your potato is wearing
- Place all of the potatoes in an area where students can see them and have students vote on their favorites.
Concept Elaboration and Evaluation
After conducting these activities, review and summarize the following key concepts:
- Potatoes are living things that depend on nonliving things, like sunlight and soil nutrients, to grow.
- Potatoes are an important food, grown and eaten by many different cultures around the world.
- Agriculture is one way that people use the physical environment.
- Geography affects what crops can be grown in an area; potatoes grow best in cool climates.
- Potatoes were first domesticated in South America, and they greatly affected European history years after being brought there by the first explorers.
Make potato stamps:
- Cut potatoes in half.
- Have students create simple designs to carve into the meat of the potato (e.g., star, heart, circle).
- Help students carve the designs in the potatoes using plastic knives.
- Mix water-based paints in aluminum pie pans or other shallow dishes.
- Instruct students to dip the potato surface into the paint, press to the surface of paper, and carefully lift the potato, leaving the print on the paper.
Use one or more of the following activities to integrate math with this potato lesson:
- Have students conduct a survey of students in their school to find the most popular way to eat potatoes—as French fries, potato chips, mashed potatoes, etc. —and graph their results.
- Review your school menu as a class to see how many times a week potatoes are served and the different ways they are cooked.
- Have students use tally marks to record findings.
- Then, have students use the data they have collected to make bar graphs comparing the different ways the potatoes are cooked with the total number of times they are served.
- Have students tear potato shapes from brown construction paper and then:
- Measure the length and width of the potato shapes in inches and centimeters, and find the perimeter of the shapes.
- Use non-standard units of measure (beans, seeds, etc.) to measure the area of the potato shapes by first estimating how many units it will take to fill the potato shapes and then filling in the shapes and recording the data.
- Have students weigh different sizes of potatoes using scales and compare the weights to various classroom materials: bottle of glue, linking cubes, etc. Then instruct students to write sentences to show their results (e.g., my potato is lighter than___, but it is heavier than ___).
Use one or more of the following activities to integrate English language arts with this potato lesson:
- Guide students to create a classroom story to explain why a potato needs so many eyes. Use multimedia to present the story.
- Read a book about potatoes. (See Suggested Companion Resources)
- Give each student two Potato Cutouts—one printed on brown paper and one on white paper.
- The brown potato will be the cover. Instruct students to write the title and author of the book you read on the cover.
- Next, have students divide the cover potato into three equal sections and cut it to make flaps that will lift to reveal the white potato beneath.
- On the white potato have students write “beginning,” “middle,” and “end” under the correct flap.
- Ask students to write one sentence to retell the main idea for each part of the story and draw a picture to illustrate each of the sentences.
- Following the potato dress up contest, ask students to select one of the following ideas to write about, and submit their writing with their potato:
- How-To: Write detailed directions to explain how you made your potato’s clothes. Use transition words.
- Persuasive: Write a detailed letter from your potato to the judge. Convince the judge to pick your potato as the winner.
- Narrative: Write a detailed story from your potato’s perspective describing a day in its life.
- Friendly Letter: Write a letter from your potato to another potato describing what your potato likes to do.
