Before the Lesson/Background Information

The Lesson
Part 1: Heartbeats
- Show students the video clip on the circulatory system.
- The students will learn how to take their heartbeats by taking their pulse on their wrist or neck. Teacher should determine which location is best for the particular class.
- While in their seats students will take their pulse and count it for 10 seconds. Teacher can work on increasing time to 30 seconds or 60 seconds, if desired.
- Teacher will display a timer on the overhead or let students know when to start counting and when to stop counting with classroom clock.
- After getting the results from the students, teacher can explain to students that the DR and nurse takes their pulse rate for 60 seconds. Teacher can multiply student results for 10 seconds by 6 to get the final heart rate.
- Teacher will record the students pulse rates on a chart and create a graph of the data.
- Alternately, teacher can pull data from the If This, Then That application. Teacher should still teach the students how to take their pulse, if counting is too difficult for children.
- Create the graph on poster board, whiteboard or Smartboard.
- Students should stand up and begin doing jumping jacks or jumping up and down for about 10-30 seconds, up to one minute.
- Students will take their pulse again and begin counting for ten seconds.
- Alternatively, teacher can partner up students to complete activity or have several students demonstrate the process with the teacher for the class.
- Teacher will graph the data after exercising.
- Teacher and students will discuss the differences in the graphs. Teacher will ask students why the graphs are different.
- Teacher will share some other exercises with the students as time permits.
Part 2: I Love My Heart!
- Students will use clay or Play-Doh to create a model of the heart.
- Teacher can choose to make any design from Google Images or Pinterest make their own Play-Doh in red. Ideas in Optional Multimedia Resources.
- Play-Doh or clay can be painted red if desired.
Part 3: Heart Healthy Snacks
Students will make two different heart healthy snacks: Frushi and Granola Yogurt Parfait. See recipe for Fruishi below.
- Granola Parfaits: Mix granola in mixing bowl using Oats, Cheerios, raisins, chocolate or carob chips.
- Students can use small cups to scoop granola on to yogurt. Enjoy!
- Fruishi: Cook rice and combine with other ingredients in advance and give each child a portion. Have students put a drop of honey or syrup onto rice to stick together. Give students choice of fruit to place on top of rice and enjoy Fruishi! Share recipe with parents.Additional yogurt can be served with Fruishi!
Coconut Frushi
Coconut Frushi Recipe
Becky Luigart-Stayner; Jan Gautro
Frushi, or fruit sushi, is one of Orange's most popular items and makes a beautiful and unusual breakfast addition. We've used oranges and raspberries for the topping, but any fresh fruit will work. If the fruit won't adhere to the coconut rice, apply it with a dab of honey.
Yield:
5 servings (serving size: 4 frushi pieces and about 2 1/2 tablespoons yogurt)

Preparation
Bring water and rice to a boil in a medium saucepan.

Remove from heat; let stand, covered, 15 minutes.
Place rice in a large bowl. Add sugar, coconut milk, and salt, stirring gently until well combined.
Cover and let stand 20 minutes.
Lightly coat hands with cooking spray. Divide rice mixture into 20 equal portions, shaping each into a ball (about 1 rounded tablespoon each).
Lightly press each rice ball into an oval between palms; place ovals on a baking sheet lined with wax paper. Top each of 10 ovals with 1 orange section, and press gently to adhere.
Top each of the remaining 10 ovals with 2 raspberries.
Cover and chill frushi until ready to serve. Serve with yogurt for dipping.
