This lesson is designed as a team teaching experience; Physical Education/Health, Math, and Science. Students will learn to identify wildflowers and their specific characteristics. They will also learn how to use a pedometer, calculate calories expended, and determine steps taken to gauge the distance traveled.
1. Identify wildflowers and their specific characteristics
2. Determine the distance traveled during the field trip activity.
3. Calculate the calories expended during the field trip activity.
4. Demonstrate the proper use of a pedometer.
5. Calculate the average stride length to determine steps necessary to walk a certain distance.
Science: Teacher needs to be familiar with the different species of wildflowers that are native to their area.
Physical Education/Health: Teacher needs to understand how to operate a pedometer and to calculate average stride length to determine steps necessary to walk a certain distance. 2,000 steps = 1 mile
You will also need a guide to common wildflowers at Grant-Kohrs Ranch or your area and a pedometer for each student or pair of students so they can determine the distance they walk and the amount of calories burned during the field trip. Example: If you are going 2 mph, weight 140 lbs; you will burn 80 calories per mile.
Day 1: In classroom, students will learn the parts of a flower. Each student will be given a handout of a flower and instructed to label the parts as they are discussed in class. They will also be required to write the definition of each part.
Day 2: Discussing 10-15 wildflowers native to your area. Teacher would dissect each wildflower visually on the "screen".
Day 3: Teacher would have 10-15 wildflowers available for student to have a hands-on experience with those wildflowers. Each student will identify each part of the wildflower for at least 7 different species.
Day 4: For the first half of this period, each student will identify each part of the wildflower that they did not identify on Day 3. For the second half of the period, each student will receive a pedometer and learn the proper usage of the instrument and teacher will explain the number of steps taken to equal a mile along with calories expended during the activity. The activity will be a field trip to identify wildflowers native to your area along with physical activity.
Day 5: Field Trip.
Students will be given a written test to identify parts of a flower and definitions of those parts.
They will also dissect 5 native wildflowers and determine the proper parts and visually identify 10 specific wildflowers.
The physical activity will be graded with a Pass/Fail format.
Grant-Kohrs Ranch has 341 know species of plants. Students will be able to compare and contrast similarities and differences of wildflowers in different areas of Montana or the country.
Dichotomous Key: A 'key' in Biology is a modeling method used for categorizing species using logical choices Angiosperm: A plant whose ovules are enclosed in an ovary; a flowering plant Gymnosperm: A plant, such as a cycad or conifer, whose seeds are not enclosed within an ovary. Sepal: Each of the parts of the calyx of a flower, enclosing the petals and typically green and leaf like Petal: Each of the segments of the corolla of a flower, which are modified leaves and are typically colored. Ovary: In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. Style: The slender part of a flower pistil, extending from the ovary to the stigma. Stigma: The stigma is part of the female reproductive system of some plants. It collects pollen for the plant or flower. The stigma is located in the pistil section of the flower or plant. Filament: The part of a stamen that supports the anther of a flower; the stalk of a stamen. Anther: the pollen-bearing part of the stamen. Stamen: The pollen-producing reproductive organ of a flower, usually consisting of a filament and an anther Receptacle: a container, device, etc., that receives or holds ... of the stem or axis that bears the organs of a single flower or the florets of a flower head Pistil: The pistil is the female reproductive part of a flower. It is composed of the stigma, style, and ovary. Pedometer: An instrument that gauges the approximate distance traveled on foot by registering the number of steps taken. Calories: the energy it takes to raise the temperature of 1 gram of water 1 degree Celsius.
