Unit Summary
This unit on metabolic reactions in the human body starts out with students exploring a real case study of a middle-school girl named M’Kenna, who reported some alarming symptoms to her doctor. Her symptoms included an inability to concentrate, headaches, stomach issues when she eats, and a lack of energy for everyday activities and sports that she used to play regularly. She also reported noticeable weight loss over the past few months, in spite of consuming what appeared to be a healthy diet. Her case sparks questions and ideas for investigations around trying to figure out which pathways and processes in M’Kenna’s body might be functioning differently than a healthy system and why. 
Students investigate data specific to M’Kenna’s case in the form of doctor’s notes, endoscopy images and reports, growth charts, and micrographs. They also draw from their results from laboratory experiments on the chemical changes involving the processing of food and from digital interactives to explore how food is transported, transformed, stored, and used across different body systems in all people. Through this work of figuring out what is causing M’Kenna’s symptoms, the class discovers what happens to the food we eat after it enters our bodies and how M’Kenna’s different symptoms are connected.

Cellular Respiration and Population Growth

Rating
0.0 stars

Two lessons and their associated activities explore cellular respiration and population growth in yeasts. Yeast cells are readily obtained and behave predictably, so they are very appropriate to use in middle school classrooms. In the first lesson, students are introduced to yeast respiration through its role in the production of bread and alcoholic beverages. A discussion of the effects of alcohol on the human body is used both as an attention-getting device, and as a means to convey important information at an impressionable age. In the associated activity, students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Based on questions that arise from this activity, in the second lesson students work in small groups as they design and execute their own experiments to determine how environmental factors affect yeast population growth.

Phenomena: DDT was a commonly-used pesticide for insect control in the United States until it was cancelled in 1972 by the United State Environmental Protection Agency (EPA).  DDT was initially used by the military in WWII to control malaria, typhus, body lice, and bubonic plague. Populations of fish eating birds, fish, plant life in certain ecosystems were affected by the use of this chemical and other similar ones.Storyline: Students at a school nearby the Delaware Bay noticed a change in osprey population.  The students wanted to figure out why this was happening. The students decided as a class to research, collect data, and explain why the environmental changes were occurring.PE Alignment: MS-LS2-1 Analyze and interpret data to provide evidence for the effects of resources availability on organisms and populations of organisms in an ecosystemMS-LS2-4 Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.  MS-LS1-7 Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism

PEI SOLS MS Food Waste
Unrestricted Use

Rating
0.0 stars

Food waste is a major contributor to greenhouse gas. Wasted food and the resources to produce that food are responsible for approximately 8% of global greenhouse gas emissions. In this storyline, students learn about the resources required to produce food through following the carbon cycle and discover how food waste contributes to climate change. They will also learn the farm to table transport chain as well as how to conduct a food waste audit. Finally, the students will research solutions to the problem of food waste that can be applicable to their own lives, their school, and their community.

El desperdicio de comida es un contribuyente mayor a los gases de efecto invernadero. La comida desperdiciada y los recursos usados en su producción son responsables por aproximadamente 8% de las emisiones globales de gases de efecto invernadero. En este caso, los estudiantes aprenderán sobre los recursos requeridos para producir comida siguiendo el ciclo del carbón y descubrirán cómo el desperdicio de comida contribuye al cambio climático. También aprenderán sobre la cadena de transporte de la granja a la mesa y cómo conducir una auditoría de desperdicio de comida. Finalmente, investigarán soluciones al problema de desperdicio de comida que pueden aplicar a sus propias vidas, su escuela y su comunidad.

Yeast Cells Respire, Too (But Not Like Me and You)

Rating
0.0 stars

Students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Each student adds a small amount of baking yeast to a test tube filled with diluted molasses. A second, smaller test tube is then placed upside-down inside the solution. As the yeast cells respire, the carbon dioxide they produce is trapped inside the inverted test tube, producing a growing bubble of gas that is easily observed and measured. Students are presented with the procedure for designing an effective experiment; they learn to think critically about experimental results and indirect observations of experimental events.
