11.30.12 Hydroponics Data, Paper Chromatography, Infectious Disease

Happy Friday!
For periods 1 and 3, your objective was to collect data on the hydroponics project and  conduct and analyze the results of a chromatography experiment in order to find the salad processing plant that processed the contaminated food. We started the lesson off with the first page of  Methods of sep mix warm up1. Then you got in your groups to record and report out your data on the growth of you plants. They are doing great: hydro 3.3hydro 3.1hydro 3.2 There is even some growth for our controls: control 3 And we are still monitoring our nutrient solution: hydro 3.4 After recording the class results for our project you got into different groups to complete the lab portion of the Paper Chromatography 2012 using 4 ink samples from the 4 salad packaging factories in Sligo town to match to the sample found at the restaurant serving the contaminated salad:chrom samples Here are a sample of your results: chrom 5chrom 4 and the final products: chrom 1chrom 3chrom 2 Can you match the unknown sample to a factory? How accurate do you think your results are? We will finish this and analyze the results on Monday.

For periods 5 and 6 you worked on infectious disease using the Prentice Hall textbook: Science Explorer: Human Biology and Health chapter 5, section 1.

All classes: There is no homework 🙂

11.29.12 Urinalysis, introduction to paper chromotography and contagious town meeting

Good afternoon 🙂 Please make sure to turn in all missing and corrected work including sub work as soon as possible. The deadline is December 10th.

For periods 1, 3, and 5 your objectives were to  use the knowledge about glucose, protein, pH and body systems to guide them through this technique to solve a pet mystery and analyze evidence to support that substances can be separated into their original substance from which they were made using paper chromatography. We started the lesson off with unscramble 1 warm up. Then we moved back into your groups to finish the Urine Analysis lab testing. Then you used your results to identify the canine culprit for Mrs. Piddle. After debriefing the lab we started discussing ways we could use these comparison skills to help find the source of the salmonella contamination in Sligo Town. We learned that samples of salad packaging have been found at the restaurant in Sligo Town where the 3 patients ate prior to getting sick. Our next step is to match the contaminated salad packaging to the 4 salad processing factories to find out if the food was contaminated there. You do not have any homework.

For 6th period, your objective was to describe how contagious viruses such as the flu are transmitted and prevented. We started the lesson off with the broken window warm up.After finishing up our discussion from part A of the think pair share intro to town meeting we watched a clip from Understanding Viruses Part 5, The Influenza Pandemic of 1918 (schneiderdf, Student) Then you found another partner to discuss what you know about vaccines using part B of the think pair share intro to town meeting. Then we came back together to discuss your responses. I received an article today Snails in the Waters, Diseases in the Villages from the National Science Foundation that fits perfectly with our discussion of contaminated water!. Then we watched a second clip, Understanding Viruses Part 6, Vaccines and the Treatment of Viruses (schneiderdf, Student). You guys had some great insight and personal experiences to share on these topics.Then we moved right into the G SR Contagious Town Meeting which we will finish tomorrow. You do not have any homework tonight!

11.28.30 Urinalysis and Identifying the contagion and food source in Sligo Town

Good afternoon! For periods 1, 3, and 5 your objective was to use your knowledge about glucose, protein, pH and body systems to guide them through this technique to solve a pet mystery. We started the lesson off with the last mystery: accident warm up. Then we watched Tim and Moby: The Urinary System (sligoms, brainpop) as a recap of the work you did yesterday on the Excretory System. Then you got into groups to complete the Urine Analysis lab where you tested for  color and odor: , protein: , glucose:  ,and pH using the SPARKS unit and pH paper: . We will finish testing and analyzing the results to find the culprit tomorrow. You do not have any homework tonight.

For period 6 your objectives were to  identify the bacteria and contaminated food item causing the illness in Sligo Town, and describe the similarities and differences in which disease is transmitted by simulating the spread of a simple imaginary disease. We started the lesson off with the Trash toss warm up. Then you went back to trying to figure out which food items all three patients in Sligo Town ate prior to getting sick using Contagion case study . We narrowed down the food items to green salad eaten on Day 1. Then we needed to compare the types of symptoms felt by the patients to the common symptoms displayed with food poisoning from the 7 bacteria we researched yesterday. We were able to confirm that the salad had been contaminated with Salmonella! Then you found a partner to start talking about how contagious illnesses are spread using think pair share intro to town meeting. We will finish this up tomorrow. You do not have any homework.

11.20.12 Contagious Town Meeting and Identifying the Source of Food Poisoning

If you are 13 years or older, please do not forget to vote for the Sligo STEM grant at https://powerabrightfuture.clorox.com/gallery/search-gal/ we are currently ranked 410!

For periods 1, 3, and 5, your objective was to describe the similarities and differences in which disease is transmitted by simulating the spread of a simple imaginary disease. We started off the lesson with masterpiece warm up. Then we moved right into the G SR Contagious Town Meeting using the G SR Contagious Town Meeting Graphic Organizer to record who you exchanged “germs” with. We had a great discussion about how to find the sources of the infections. You then worked on the analysis questions. If you did not turn them in it is homework. I will be out for the holiday until next Tuesday but the work done in class in my absence will be collected each day and graded when I get back. I hope you have a fantastic holiday!

For period 6, your objective was to identify the bacteria and contaminated food item causing the illness in Sligo Town. We started the lesson off with snack shack warm up. Then we went over part 1 and the first half of part 2 of the Contagion case study using the Food Poisoning Overview  and developed some hypotheses for why your body responds to infection. You had some great insight and examples for this section. Then you got into groups and  rotated around the room to collect information about seven different bacteria: Salmonella foodpoisoning article, vibrio poisoning, campylobacteriosis poisoning , listeriosis poisoning, E. coli poisoning, botulism poisoning, staph poisoning using the Contagion case study . Then you started to compare the foods eaten by the first 3 patients who showed symptoms of food poisoning in part 4 with the goal of matching the foods eaten and the symptoms of the illness to the 7 different bacteria we researched to identify the contagion.  You do not have any homework. I will be out for the holiday until next Tuesday but the work done in class in my absence will be collected each day and graded when I get back. I hope you have a fantastic holiday!

We will finish this tomorrow. You do not have any homework.

For period 6 your objectives were to  give feedback on the course so far and collect data on the hydroponics system. You had an opportunity to give me feedback on how the course is going so far with the science survey updated. I will shar the responses with you tomorrow. Then you picked up the hydroponics data sheet only with media changes. We will use this to collect data on our plants in the raft system over the next 4 weeks and write-up a final report using this information. You do not have any homework.
