Discussion questions Review student demographic information for your school or school district. Does your ELL population reflect the trends described by Dr. Specifically, what percentage of students is ELL this school year as compared to five years ago? What is the primary language spoken by ELLs at home?
Place the three cups on the white paper. Write Cold, Room-temp, and Hot near its cup. Observe for about 1 minute. The color and sugar in the room-temperature water dissolve somewhere between the cold and hot water, but are more similar to the cold than the hot.
There are actually two processes happening in this activity.
The color and sugar are dissolving in the water but they are also diffusing in the water. The temperature of the water affects the amount of dissolving but it also affects the rate of diffusion.
Record and discuss student observations. How do you know? Based on their observations, students should conclude that the hotter water causes more dissolving.
Students may have noticed a greater difference in the amount of dissolving between the hot and the room-temperature water than between the room-temperature and the cold water.
If no one comments on this, suggest that there is a difference. Explain Discuss how differences in molecular motion caused more of the sugar coating to dissolve in hot than in cold water. What are the differences in the way water molecules move in cold, room-temperature, and hot water?
Students should remember that water molecules move faster in hot water than in cold.
Why do you think sugar dissolves better in hot water than in cold water? The reason why sugar dissolves at a faster rate in hot water has to do with increased molecular motion. The added energy in the hot water causes water molecules to move faster and sucrose molecules to vibrate faster.
This added movement tends to make the bonds between sucrose molecules easier to overcome. When faster-moving water molecules attach to sucrose molecules, a higher proportion of these sucrose-water interactions have enough energy to pull sucrose molecules away from other sucrose molecules, so the rate of dissolving increases.
Why do you think there is a greater difference in the amount of dissolving between the hot and room-temperature water than between the room-temperature and cold water? There is a greater difference in the rate of dissolving because there is a greater difference in temperature between hot and room-temperature water about 30 degrees than between room-temperature and cold water about 15 degrees.
Explore Either do a demonstration or show a video to investigate whether all substances dissolve much better in hot water than in cold water.JA Be Entrepreneurial challenges students, through interactive classroom activities, to start their own entrepreneurial venture while still in high school.
The program provides useful, practical content to assist teens in the transition from being students to productive, contributing members of society.
Here is an example of an Executive Summary that was written in my ELA class by a middle school student for a DARPA/NASA project. The assignment asked students to conceptualize and research how humans might colonize a planet within years.
Free lesson plans covering many subjects for middle school students. Write a summary based on class discussion that is no more than five sentences long. Independent Practice Students will create the two columns in their reading journal and use it to summarize their independent reading text.
Ereading Worksheets Free reading worksheets, activities, and lesson plans. Site Navigation. I was wrong in doing this. Now I always teach my students how to write summaries.
Writing a good summary is not as easy as it may appear. It actually requires quite a bit of finesse. I teach high school ELL and was looking for good nonfiction. Jun 26, · How to Write a High School President Speech.
