In which John Green teaches you about disease, and the effects that disease has had in human history. Disease has been with man since the beginning, and it has shaped the way humans operate in a lot of ways. John will teach you about the Black Death, the Great Dying, and the modern medical revolution that has changed the world.
Students demonstrate the erythrocyte sedimentation rate test (ESR test) using a blood model composed of tomato juice, petroleum jelly and olive oil. They simulate different disease conditions, including rheumatoid arthritis, anemia, leukocytosis and sickle-cell anemia, by making appropriate variations in the particle as well as in the fluid matrix. Students measure the ESR for each sample blood model, correlate the ESR values with disease conditions and confirm that diseases alter blood composition and properties. During the activity, students learn that when non-coagulated blood is let to stand in a tube, the red blood cells separate and fall to the bottom of the tube, resulting in a sediment and a clear liquid called serum. The height in millimeters of the clear liquid on top of the sediment in a time period of one hour is taken as the sedimentation rate. If a disease is present, this ESR value deviates from the normal, disease-free value. Different diseases cause different ESR values because blood composition and properties, such as density and viscosity, are altered differently by different diseases. Thus, the ESR test serves as a real-world diagnostic screening test to identify indications of the presence of any diseases in people.
Il est important de pouvoir bien communiquer. L’élève aura l’occasion de prendre la parole de façon spontanée à tous les jours.
Ici il y a de la communication orale et le prise de parole informelle. On y retrouve des documents à télécharger.
Science Background:
• Liquids have characteristic properties based on the molecules they are made of.
• The properties of liquids depend on the attractions the molecules of the liquid have for each other and for other substances.
• Liquids can dissolve certain other liquids, depending on the attractions between the molecules of both liquids.
• Polar liquids, like water, dissolve other liquids which are polar or somewhat polar.
• Polar liquids, like water, do not dissolve nonpolar liquids like oil.
Materials: Water, Vegetable oil, Isopropyl rubbing alcohol, 70%, Corn syrup, 3 Clear plastic cups, 3 Small cups, 3 Popsicle sticks or stirrers
This task asks students to find a linear function that models something in the real world. After finding the equation of the linear relationship between the depth of the water and the distance across the channel, students have to verbalize the meaning of the slope and intercept of the line in the context of this situation.
This short video and interactive assessment activity is designed to teach fourth graders about distances between points on one route (metric units).
The purpose of this task is meant to reinforce students' understanding of rational numbers as points on the number line and to provide them with a visual way of understanding that the sum of a number and its additive inverse (usually called its "opposite") is zero.
This task asks students to find equivalent expressions by visualizing a familiar activity involving distance. The given solution shows some possible equivalent expressions, but there are many variations possible.
This is an activity about the Hubble Deep Field image, an observation of one small area of sky that contained no previously-detected objects. The long time exposure of this image allows us to detect some of the most distant objects seen in our Universe. Learners will view an image of the Hubble Deep Field and identify how many distant galaxies are visible as well as the types of galaxies they might be. Observations will be taken a step further to infer predominant age of a galaxy and determine if there are any trends in age (color) versus galaxy size or type and, ultimately, if the distant Universe appears relatively uniform. This activity is Astronomy Activity 4 in a larger resource, titled "Space Update."
Students pass around and distort messages written on index cards to learn how we use signals from GPS occultations to study the atmosphere. The cards represent information sent from GPS satellites being distorted as they pass through different locations in the Earth's atmosphere and reach other satellites. Analyzing GPS occultations enables better global weather forecasting, storm tracking and climate change monitoring.
