Overview:
|
|
Using ten science activities, students will be introduced to important nutrition concepts. These activities are used to teach abstract concepts in more concrete ways. Each activity includes a "What Happened" section that explains in scientific terms what happened or what caused the scientific reaction. Each learning activity also has a "How Does This Relate" section, showing to which nutritional area the activity relates. This lesson can be used to teach health, nutrition, or food - related topics. |
|
Approximate Duration: 1–5 class periods (50 minutes each) |
Content Standards:
- Science as Inquiry
The students will do science by engaging in partial and full inquiries that are within their developmental capabilities. - Physical Science
Students will develop an understanding of the characteristics and interrelationships of matter and energy in the physical world. - Life Science
The students will become aware of the characteristics and life cycles of organisms and understand their relationships to each other and to their environment.

Interdisciplinary Connections:
- Mathematics : Measurement
In problem-solving investigations, students demonstrate an understanding of the concepts, processes, and real-life applications of measurement. - Health Education : Standard 1
Students will comprehend concepts and strategies related to health
promotion and disease prevention.
- Health Education : Standard 3
Students will demonstrate the ability to practice positive health
behaviors and reduce health risks.
|
Educational Technology Standards:
- Demonstrate the operations of a computer (e.g., touch-keyboarding skills, save, organize and back-up files) and other peripheral devices (scanner, digital and video cameras, VCR, laser disc player) at an intermediate level.
( 6 )- Use information, media, and technology in a responsible manner which includes following the school's acceptable use policy, adhering to copyright laws, respecting the rights of others, and employing proper etiquette in all forms of communication.
( 4, 5 )- Use multimedia tools and desktop publishing to develop and present computer-generated projects for directed and independent learning activities.

Objectives:
The students will conduct scientific investigations; present the results of experiments; communicate observations and learning activities in oral formats; communicate scientific procedures, information, and explanation; identify elements and compounds found in common foods; measure properties of objects using appropriate materials and tools (Experiment 3); create mixtures and separate them based on differences in properties (Experiments 5 and 6); identify important chemical reactions that occur in living systems; observe changes in matter and cite evidence of chemical change; compare and contrast the pH of acids and bases using a variety of indicators (Experiment 4); investigate human body systems (including digestive and skeletal systems) and their functions; and recognize the food groups necessary to maintain a healthy body. |
Lesson Materials and Resources:
Materials for each learning activity are listed with that particular experiment.
|
Technology Tools and Materials:
Hardware:
computer with Internet access
Software:
KidPix, PowerPoint, or other presentation software
Other:
|
Background Information:
The students should have knowledge of conducting science experiments and writing lab reports, although these classroom projects are more correctly called learning activities or investigations. Students should also have a knowledge of searching the internet. |
Lesson Procedures:
- Before the lesson begins, the teacher will print copies of Activities 1-10 from the Reproducible Materials section and gather materials needed to conduct the experiments. The teacher will review with the class the proper steps for conducting experiments. Discuss with the class how the activities relate to foods and nutrition.
- The students may work individually or in groups. As students conduct their activities, instruct them to complete the following in their science notebooks: name of experiment, hypothesis, observations, analysis, and conclusion. Additionally, the students should highlight the relationship of the activity to foods and nutrition.
- The students will prepare and present their results to the class using KidPix or PowerPoint presentations. If software is not available, students may design posters to illustrate the results.
|
Assessment Procedures:
Students could be evaluated based upon
- completion of science journals/responses,
- content and group work of slide show presentation, and
- accuracy of oral responses given in discussions during each activity.
|
Accommodations/Modifications:
Consider different learning styles and abilities when planning this lesson.

Reflections:
Most of the background information necessary to teach this curricular area can be found at the Fresh Starts Web site, www.freshstarts.com.
The purpose of this series of
activities is to enable the students to see chemical reactions in foods. Vitamins and minerals are such abstract concepts that it is difficult for younger students to understand how these nutrients function in the body. These science investigations are meant to visually show students how foods can work inside the body to make it stronger. |
