Nutritional Analysis

Unit I Assessment

Introduction

In Chapters 3 and 4 of the textbook, you learned that the body needs various macro and micronutrients in order to function properly. You also learned about cellular metabolism and what the human body uses as a fuel source. This all seems simple at first glance; however, it can be difficult to determine whether or not we are getting what our body needs. Even when we know what our body needs, it becomes even more difficult to make sure we are supplying our body with those needs. The car you drive most probably requires gasoline in order to function properly. When you need to go somewhere, you make sure you have enough gasoline in the tank to reach your destination. If you do not, you probably stop at a gas station and fill your car’s tank with gas. You do not pour cola in the tank or jelly donuts; you put gas because that is what it needs. Why do we put cola and jelly donuts in our bodies when we do not need them? Often time, it is difficult to determine what is in the foods that we eat. Sometimes it is hard to determine if the food contains the correct nutrients or processed foods that our body does not need. This lab exercise will help you learn how to read nutritional labels and determine what your body needs to function properly.

Objectives

1. Analyze nutritional information based on what the body needs to function properly.

2. Calculate BMR, BMI, and caloric burn.

Materials

You will not need any extra materials other than your textbook and your computer (with internet access) to complete this lab.

Plant Transpiration

Unit VIII Assessment

Introduction

If you have not already, you or someone you know will try to grow avariety of plants either inside your house or outside in a garden. What type of soil do you need? How often should you water the plants? Should you plant them in full sun? Why do some plants need less water and some more? These are questions that many people haveabout plants. In this activity, you will have a chance to manipulate different variables tosee how much water some plants use and how much some lose through transpiration.

Objectives

1. Conduct virtual experiments to determine factors that affect transpiration.

2. Compare and contrast sustainable and unsustainable farming practices.
