11.30.11 Testing for Life

Hello and welcome back! Today’s objective was to conduct simple chemical tests to detect the presence of organic molecules in a variety of substances, some “once living” some “never living” some “mystery solutions”. We started the lesson with Alive Not Alive List before list where you checked off whether the liquid was once live, never alive, or not sure. Then we went over the background information for the Testing for Life Molecules Lab. Then we got into groups where you answered the pre-lab questions, chose your testing material and started testing your materials for starch and lipids using the Lab Station directions. Tomorrow we will test for protein and glucose. No homework tonight :).

11.23.11 Hydroponics System data and farewell

Good afternoon and happy early Thanksgiving! Today’s objective was to collect the 4th week of data from our hydroponics systems. We started the lesson with part 5 of the periodic practice. Then you turned in your element nutrient quiz. We then started collecting data using the lab report observation sheet. Dr Baizer (our NIH volunteer) suggested that we record all the data, average out the changes in height and graph the results to see if there is a trend. We will do that next week along with the analysis of this experiment. Sam and I took the fish out to the courtyard for their new pond. We’ll keep the control basil plants growing until they can be replanted and then taken home 🙂 Have a fantastic break and I’ll see you next Wednesday!

11.22.11 Nutrient and Periodic Quiz

Almost there! One more half day, we do it. So what did we do to pass the time today? Our objective was to compare the nutrients required for human health and how the periodic table is organized. We started the lesson with periodic practice, the top section on the second page. We then collected the missing information on our D SR Essential Nutrients Chrt graphic organizer as we observed the nutrient posters. We finished up with the “open” element nutrient quiz for periods 2 and 4 due tomorrow first thing in class. For period 6, your “open” element nutrient quiz acc is due at the end of the period tomorrow.

11.21.11 Nutrient Gallary Walk

I think knowing it is a short week makes the time go by that much slower, what do you think? Anyway, here’s what we did today:  we were to describe the role and sources of all the essential nutrients found in the food we eat by preparing and participating in a gallery walk. We started the lesson with the bottom of the periodic practice. Then we went over pages 2-3 of the Family Webquest. Then we got into groups to finish the rest of the poster from your expert group. Then you walked around the room to collect the rest of the information on your D SR Essential Nutrients Chrt by looking at the other posters. Nice job! Tomorrow we will have a review activity to use this nutrient information and the work we’ve done on the periodic table. 1 and a half days left!!!!

11.18.11 Nutrient Gallery

Happy Friday! Today’s objective was to describe the role and sources of all the essential nutrients found in the food we eat by completing a jigsaw activity to prepare for a gallery walk. We started the lesson with section 2 of the periodic practice. We then played four corners describing the 4 major nutrients, carbohydrates, fats, vitamins and minerals, and proteins. Then we got into groups to become an expert on your topic using theses resources: D SR Gallery_Walk_InformationWashington Post Nutrients and BioMolecules. You recorded your information on the D SR Essential Nutrients Chrt and then used that information to create your poster. On Monday we will collect the rest of your information from your classmates poster. No homework today. 🙂

11.17.11 Periodic Table Wrap up

Good afternoon! Is the Elements song stuck in your head? If not, give it another listen:  Can you do better than Daniel Radcliffe (Harry Potter)? Today’s objective was to describe how and why the periodic table is organized. We started the lesson with part one of the  periodic practice. Then we went over page one of Family Webquest. We then discussed the results of the Periodic Table Families Lab. We finished up by viewing the reactivity of alkali metals . Tonight’s homework is to finish pages 2-3 of the  Family Webquest using the Science Explorer PT text.
