10.28.11 Unit Test

Happy Friday! Congratulations, we’ve made it through the first marking period. Time flies when we’re having fun. Today our objective was to complete the unit exam. When we come in on Tuesday we’ll be collecting data on the hydroponics system. Enjoy your weekend, and have a happy Halloween!

10.27.11 pH

Good evening. I hope you had a good day. Remember that all work is due tomorrow and your unit test is tomorrow. Today, your objective was to describe the characteristics of acids and bases by acids and bases worksheet.

10.26.11 Study Guide and pH

Good afternoon. Remember your test is FRIDAY and all work is due FRIDAY!!!

For all classes: we had 2 objectives today:first we were to review the concepts for part 2 of the hydroponics unit. We did that by going over the Hydro part 2 study guide 2011 answer key. Next we were to investigate the characteristics of pH and the tools used to measure pH. We did that by going over the results of Who Dun It pH Chemical Analysis . Your homework is to STUDY!!!!!! That means quizzing yourself, explaining the concepts to a parent or sibling, drawing pictures to explain concepts, not just reading over your notes! If you have any questions, ask here as a comment and I will respond. Other students may respond too by leaving other comments. Have a great night!

10.25.11 pH: Who Dun it?

Good afternoon! We are getting down to wire here for the first quarter. All missing corrected work needs to be turned in by Friday in order to receive credit. We will be going over the in class tomorrow for the Summative unit test Friday.

All classes: Our objective today was to investigate the characteristics of pH and the tools used to measure pH to solve a crime. We started the lesson with a pre-assessment and then took some brief notes on pH, acids and bases on Acids and Bases Notes . Then we completed the lab to find out who the candy caper was in Who Dun It pH Chemical Analysis .

10.24.11 Mixtures and Cellular Respiration

For 2nd and 4th periods: Our objective was to investigate the solubility of a variety of substances in order to develop an understanding of the system by which plants absorb nutrients. We started the lesson going overt the requirements of yeast to perform cellular respiration: warm water, oxygen, and glucose. We then went onto Mixtures and Solutions Notes while following the flipchart then we investigated the solubility of hot chocolate powder versus chocolate chips (remember solubility is impacted by temperature, surface area and stirring). Tonight’s homework is to work on the Hydro part 2 study guide due Wednesday.

For 6th period: Our objective was to analyze how organisms use sugar to create energy and to identify carbon dioxide as a product of respiration. We started by observing our lab results from the Cellular Respiration Lab and completed the analysis questions. We then SR Exchanging Gases Concept Map. Your homework is to work on the Hydro part 2 study guide  due Wednesday.

 

10.20.11 Cellular Respiration

Good Thursday! Remember no school Friday, I know that makes you very sad 🙂 But you have your study guide to work on so you can still enjoy science! I need to make a correction to the study guide. I copied a question wrong. #1 should not have table. The question should read:

Students are investigating the physical properties of three solid mixtures by placing each solid mixture in liquid water. What physical property are the students testing?

a. solubility
b. conductivity
c. boiling point
d. melting point
Sorry of the confusion.
For 2nd and 4th periods: Our objective was to use Bromothymol blue to determine if carbon dioxide is produced by yeast in cell respiration. We started the lesson going over your grade reports. Remember all missing corrected work needs to be in by October 28th for it to count. Then we reviewed what cellular respiration is, process by which cells break down simple sugars to release energy. We then took a look at our lab results from Cellular Respiration Lab to see if the yeast produced carbon dioxide during cellular respiration. Can you explain why test tube 2 is yellow and test tube 1 and 3 are blue?    Tonight’s homework is to work on the Hydro part 2 study guide  due next Wednesday. Enjoy your weekend!
For 6th period,our objective was to investigate how organisms use sugar to create energy and to identify carbon dioxide as a product of respiration. We started the lesson with Conservation warm up. Remember that the mass before a reaction equals the mass after a reaction in a closed system. We then watched Tim and Moby introduce Cellular Respiration. We then set up the Cellular Respiration Lab. We will take a look at the results on Monday. Tonight’s homework is to work on the Hydro part 2 study guide . Enjoy your weekend!

10.19.11 Cellular Respiration and Conservation of Mass

Hello!

For 2nd and 4th periods: Our objective was to investigate how organisms use sugar to create energy and to identify carbon dioxide as a product of respiration. We started our lesson with Conservation Raffle. We then went over  What goes in must come out. Remember, gas does have mass! We were introduced to Cellular Respiration with Tim and Moby (username: sligoms, password: brainpop). Then we got into groups to set up the Cellular Respiration Lab. Here’s what our test tubes looked like today: , we’ll check the results tomorrow to see if the yeast produced carbon dioxide through cellular respiration. Tonight’s homework is to start the Hydro part 2 study guide , your test is next Friday.

For 6th period, our objective was to analyze how the raw materials are used to make simple sugar molecules and prove the law of the conservation of matter. We started the lesson going over the models we created yesterday with Assembling Raw Materials .  Remember, the number of atoms we start with must be the same as the number end with. It’s not magic, its science! We investigated the law of conservation of matter in a closed system with What goes in must come out. We answered the question, does this  equal this ?
