Nutrition: What are Nutrients?

Science ObjectDigital resources are stored online in your NSTA Library.

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach This Science Object, co-developed between FDA and NSTA, is the third of four Science Objects in the Nutrition SciPack. It explores nutrients and the specific physiological functions associated with each nutrient. Carbohydrates, fats, and proteins provide energy for body movement and physiological processes; proteins provide building material for body tissue as well as substances for important physiological processes; and vitamins and minerals regulate body processes. Water carries nutrients, provides an environment for many physiological functions and is part of the composition of the body itself. Getting too much or too little of these nutrients can cause undesired effects; good nutrition involves getting the right amounts {and in the right combinations}. Other substances in food, including phytonutrients, may also have important health benefits that are not yet well understood.

Anyone who has been involved in the Weight Watcher program will understand the science behind the food you NEED to eat and the food you need to avoid. This science object reviews everything related to reaching and maintaining a healthy diet.

I really enjoy Science Objects. In 1-3 hours, the Nutrition: What are Nutrients? Science Object will help me re-learn, refresh, or learn for the first time some critical science concepts I will have to know to obtain my Science Educator credentials. I appreciate that I can complete them at my own pace, and that, if used as park of a SciPack, I have access to a content expert to go to for help. The NSTA Learning Center Science Objects are very beneficial! Not only will they enrich my teaching, the knowledge will enrich my life.

I really enjoyed this resource as I will be using it to teach students about nutrition and it explains what nutrients are and what purpose they serve in the human body.

There are many types of nutrients that help our bodies function throughout the day. A food pyramid would be good to use and have up in my PE class to go over to see what type of nutrients are being put into their bodies. Having the students know this would be beneficial for the students to help them with learning in the class room with the understand that is energy needed on a daily basis. I would explain how the nutrients would be helping them in their school and learning. The students need to have a brief summary of the nutrients and what body part or benefit is to come. In my PE classes I have touch a little on eating habits the food pyramid, and importance of being active daily.

The content in this section is presented well and the interactive portion is fun to work with. My suggestion is to have a link to the beginning of the section on the last page (credits or glossary) so one can get back to the first part easily. As it is, you have to page back, which is a bit tedious.
