The eating and exercise habits you develop at this age will influence how you look and feel when you’re older. Food and drinks are made of 3 main components – fat, carbohydrates and protein. You get some calories of energy from each component and each component is used in your body in different ways. Calories are the amount of energy that a food or drink will produce when it is digested by the body. To maintain a healthy weight, you need to balance the amount of calories you consume through food and drink with the amount of calories you burn (or use up) through physical activity. In this activity, you will choose items you will like to have for lunch. You will calculate the amount of calories contained in this food and how much exercise you need to do in order to burn those calories and maintain a healthy weight. Part 1: Eat!!! 1. In the table below, record the 5 items you chose. Fill in the rest of the table and write the total number of calories for each column. Food Total Calories Calories from Fat Calories from Carbohydrate Calories from protein Total What percent of the total number of calories in your lunch comes from fat? _____ From carbohydrate? _______ From protein? _________ 3. Nutritionists recommend that, at most, 30% of the total number of calories comes from fat, about 12% of the calories from protein, and at least 58% of the calories from carbohydrates. Does the lunch you chose meet these recommendations? _________ 4. Plan another lunch. This time, try to limit the percent of calories from fat to 30% or less, from protein to between 10% and 15%, and from carbohydrate to between 55% and 60%. Food Total Calories Calories from Fat Calories from Carbohydrate Calories from protein Total What percent of the total number of calories in your lunch comes from fat? _____ From carbohydrate? _______ From protein? _________ Part 2: Eat More and Exercise!!! Research says that, children between the ages of 9 and 13 need to consume an average of 2000 calories a day in order to carry out their regular functions. If you want to lose weight in a healthy way, you need to use more energy than you consume. 1) What percent of your daily 2000 calories come from your total lunch in Part A? 2) A) How many calories are left for breakfast and dinner? B) What food would you have for breakfast and dinner so that you meet your 2000-calories-per- day limit (you can go over 2000 calories if necessary but not too much over)? C) What percent are your breakfast and dinner calories of your 2000-calories-limit? 3) A) Go to http://www.caloriescount.com/getMoving.aspx B) Pick an activity. Choose the amount of time that you’ll do the activity for. Type in your weight in pounds (use google search to convert your weight from kilograms to pounds if you need to). C) Click on “Compute Calories” and find out how many calories you will burn by engaging in the physical activity that you choose. D) What percent is the calories that you burn by doing this exercise, of the 2000 calories that you consume per day? E) If people eat too much on a certain day, they might want to burn off those extra calories on the same day. How long would you have to do the activity that you chose in A to burn 100 calories? FPD – Compacting 4 Fractions, Percentages and Art Be Artistic with Fractions!!! Create a sample mural on the white paper that you are given.

Upload the pictures for your work into a folder called “FPD-Compacting5” on GoogleDocs when you’re done. It’s all in your genes!!! Mirror, mirror on the wall... why do I look like my parents at all? You've been selected to join a team of genetic researchers to find an answer to this very question. On this adventure, you'll learn how to use a Punnett square. Then you'll gather information about the genetic traits of your classmates. You'll also make genetic predictions based on an analysis of your findings. So grab your lab coat and your probability and statistics tool kits. This is one adventure you don't want to miss. The reason you look the way you do is because you have inherited genetic material (DNA) in your cells from your mom and dad that make you look the way you do. Half the DNA in your cells is from your mom and the other half is from your dad. If the blue circle below is a cell in your body, the red lines are DNA from your mom and the yellow lines are DNA from your dad. GENE 3 GENE 2 GENE 1 The DNA from your mom and dad are divided into pieces called GENES. Each gene codes for a certain trait. Some genes are DOMINANT, in that they take over and other genes are recessive, in that they remain hidden. More people express traits from dominant genes and fewer people express traits from recessive genes.

This is how the document will look: Geometry – Assignment 4 – Regular Track Angles and Area and Perimeter of Triangles and other Polygons Copy and paste this assignment into another word document and work on that document directly. Objective: In this assignment you will investigate how to use triangles to find the sum of all angles in any polygon. You will also learn how to use Sketchpad to calculate area and perimeter of triangles and other polygons. 1) Open up Geometer’s Sketchpad. 2) Select the polygon tool: 3) Make a triangle on your sketch page. 4) Measure all the angles of your triangle. Your sketch should look something like this now: These are the angle measurements. 5) Select all the angle measurements and click on the “Number” menu and click on “Calculate”. This calculator should appear on your screen. 6) Select the angle measurements one at a time and sum them up using the calculator. 7) Your sketch should look something like this now: 8) Connect the points of your triangle with lines to outline the perimeter of your triangle. Your sketch should look something like this. 9) Add a point somewhere on your sketch beside your triangle. 10)Connect the new point to 2 different points (points that are next to each other) on your triangle. Your sketch should look something like this now. Question 1: If the inside of the four points on your sketch made the area of a shape, it would have 4 sides. What kind of a shape have you made? Question 2: Predict what you think is the sum of all angles of this 4-sided shape. Support your prediction with reasoning. 11) Calculate the angle the new point makes inside your 4-sided shape. Question 3: Calculate the actual sum of all angles in your 4-sided shape using the calculator in Geo Sketchpad. Was your prediction correct? If your prediction was not correct, where do you think you went wrong? Why is the correct answer actually correct? 12)Now make a fifth point beside your 4-sided shape and connect it to 2 points on your 4-sided shape. Your sketch should look something like this now: Question 4: If the inside of the five points on your sketch made the area of a shape, it would have 5 sides. What kind of a shape have you made? Question 5: Predict what you think is the sum of all angles of this 5-sided shape. Support your prediction with reasoning. Question 6: Calculate the actual sum of all angles in your 5-sided shape using the calculator in Geometer’s Sketchpad. Was your prediction correct? If your prediction was not correct, where do you think you went wrong? Why is the correct answer actually correct? Question 7: Do you think all 5-sided shapes have the same sum of all angles? Why or why not? How would you test this prediction using Geometer’s Sketchpad? Question 8: What is a 6-sided shape called? Question 9: What do you predict is the sum of all angles in a 6-sided shape? Why? 13) Make a NEW 6-sided polygon using the polygon tool. Question 10: Calculate the actual sum of all angles in the 6-sided shape by measuring the angles and using the calculator in GeoSketchpad. Was your prediction correct? If your prediction was not correct, where do you think you went wrong? Why is the correct answer actually correct?
