  • Project Groundhog: The students will determine the groundhog prediction of either six more weeks of winter or an early spring and see if the prediction was accurate by recording daily weather data for six weeks. Over that six week period the students will be comparing their weekly data with schools around the USA and Canada using the Project Groundhog website.
  • Wonderful whales: Students will gain knowledge of whales: the kinds of whales, the characteristics of whales, and the habitats of whales. Math skills will be incorporated into the teaching facts about whales.
  • Plant power: Students will plant their own seeds in potting soil and measure plant growth. Before the students' plants are visible above the soil, students will explore the parts and functions of classroom plants and compare growth between the classroom plants. Using the weather channel website, students will predict whether the day's weather conditions are excellent, good, or poor for plant growth.

Learning outcomes

Students will:

  • observe the characteristics of the outside of a pumpkin.
  • learn the life cycle of a pumpkin.
  • measure a pumpkin using nonstandard measurements. They will then graph their results as a class.
  • observe the inside of the pumpkin with their five senses.
  • taste and describe pumpkin seeds.

Teacher planning

Time required for lesson

4.5 hours

Materials/resources

  • pumpkins of various sizes and shades
  • double pan balance scales
  • buttons
  • teddy bear counters
  • string
  • Unifix Cubes
  • chart paper
  • markers
  • paper
  • pencil
  • pumpkin carving kit with pumpkin saw
  • vegetable oil
  • electric skillet

Pre-activities

Students will:

  • make a KWL chart about pumpkins.
  • learn how to use a double pan balance scale and counters.
  • learn how to measure using string and Unifix Cubes.

Activities

  1. The students will observe the characteristics of the outside of a pumpkin. They will list the observable characteristics as a class on a circle map. They will then write in their own words a description of a pumpkin and draw a picture.
  2. They will share a book on how a pumpkin grows. They will then sequence the events from planting the seed to harvesting. They will then make a mini-book about pumpkins. (See examples one and two.)
  3. The students will predict which small pumpkin weighs the most. They will then measure the small pumpkins using a double pan balance scale and teddy bear counters. After they measure the pumpkins, the class will graph the number of bears each pumpkin weighs.
  4. The students will predict if the heaviest pumpkin is also the largest around. The teacher will record the students’ thoughts. They will then measure the pumpkin using string. They will mark the string with a marker. Next they will measure the string by joining together Unifix Cubes. The class will graph the results and discuss the findings.
  5. The students will predict what the inside of the pumpkin is like. Then the students will explore the inside of the pumpkin. The teacher will open the top of the pumpkin using a pumpkin saw. S/he will then scoop out some of the pumpkin seeds and then put the seeds in the bucket of water. The students will then take turns scooping out the pumpkin seeds and placing them in the bucket. After all the seeds have been removed from the pumpkin, students will wash and strain the seeds. The seeds will then be set aside to dry. The class will then describe how the inside of the pumpkin felt, smelled, sounded, and looked.
  6. The students will observe as the teacher roasts the pumpkin seeds. Place a light coating of oil in the electric skillet. Cook the seeds at three hundred degrees until they are golden brown. Let cool and lightly salt. Allow the students to taste the pumpkin seeds. Let them describe how the seeds tasted. Finally, have the students color a picture of how the seed looked before and after it was roasted.

Assessment

  • Teacher observation
  • Oral responses during class discussion
  • Sequencing activity
  • Picture of seed before and after roasting

Comments

I recommend visiting a pumpkin farm as a culminating activity to this unit.

I also recommend using the pumpkin for a classroom Jack-O-Lantern.
