Anita+Kreide

Also you said "add names" does that mean our names? If so where? Sam :)

Mrs. Kreide- Should Cailey, Hanna, and I (Does Detergent Brand Have an Effect on Cleaning?) bring in our cloths or do you think just our pictures will do? We have before and after. They have gotten a little moldy because they were not dry all the way in the dryer. Also I do not understand what u meant by a title for materials and procedures, do we just have Materials and Procedures as our title? Thank you so much for your input on our board it helps a lot!! 5/15/12 Thanks, Sam :) Yikes guys I am soooo sorry I did not get to this site in time to respond before the projects were due. Don't worry about the names it was not part of the judging rubric so you will not get marked down in anyway. No worries about not bringing the clothes the pics were enough. I meant that the title materials and procedures needed to be in the right location on the board with a list of materials below materials title and the step of the procedure below the procedure title.See you tomorrow night! Mrs. Kreide

Hello! This is Francesca Maramonte from Fruit Electricity. I was hoping to show you my Results and Conclusion and Discussion pages tomorrow so you could look over it? I made many changes hoping it works! I would really appreciate it, if not that's alright. Thank you, Francesca 5/14/12

Francesca either email it to me at kreidea@yahoo.com or send it to the office and they will get it to me. Email would be best because i could read and send back quickly as the boards are due on wed. As long as u answered the questions on the worksheet it should be great.

Mrs. Kreide, At the science fair, can we put the dishes containing the bacteria in front of the board? -Emily Woodward and Lauren Mitchell ("Are there more bacteria in a bedroom or a bathroom?") 5/13/12 Yikes sorry again for the late response I didn't see the post. Dishes would be great!

Mrs. Kreide, My group and I were wondering if we had to put our names and group number on the board ? -Gianna, Nikala, and Frankie

Yes, please put names on the board next to the title. Don't worry about the number, I will have number labels for every board.

Mrs. Kreide - Please change the title of the project for David Hugo, David Flores, Dean Pacheco and Marcus Change to "Ball Bouncing Dynamics". Thanks. David Hugo Got it...sound like a great title!

Mrs. Kriede, Do we have to type the purpose and hypotheses? I recall that we had to fill it out (paper and pencil) on a ditto you sent a couple months ago. From, Jianna and Anna

On the last worksheet is a diagram of the project board. Everyone's boards should have all of the same titles in all the same spots on the board. Whatever is easier for the judges to read is what you should put on the board. Typing or stencil or clear writing is totally up to you..I am sure your board will look great!

Mrs. Kriede, What should we wear for the night of the Science Fair? Do we just wear our uniforms? -Theresa and Joanna :)

No uniforms unless you want to wear them. I would say stick to free dress rules and wear something nice that makes you feel comfortable.

Mrs. Kreide, My group is Cailey Purkey, Hanna Yi, and myself Sam Tobias. Our project is "which detergent cleans better?" I was wondering for the conclusion is it what we concluded as a group or is it what are conclusions on the results were? If it were the latter would it just be weather we thought this detergent worked best over this detergent? *sorry its late :/* --Sam Tobias

Hi All, Great question! It is what did you conclude as a group based on the data that you collected from your experiment. So if detergent A worked the best state that and include why you think that is. Did detergent A have an ingredient that the other detergents did not have? Then answer the questions on worksheet 4 under conclusion (extra copies are under handouts on the wiki). Did you reject or accept your hypothesis? restate your experimental procedure. what would you have changed? did you control your variables? could you make changes next time to better control for variables? etc see the worksheet for the rest. Hope this helps. Please let me know if there is anything else? Mrs. Kreide

Mrs. Kreide, Josie and I have a question for you: We did are ladybug expirement; but didn't get to run the expirement again, for one of the groups there was 10 eggs an the other group 13 eggs. Because the numbers are so close, would we still say that are hypothesis was accepted or would we say rejected?

~Brenna Starkey and Josie DeBellis

Yes very close results! I would say that 10 to 13 is so similar that you could say the data might suggest that the type of food did not make a difference in the number of eggs laid. However, because the numbers are not exactly the same I would state in your paper that you preliminarily reject your hypothesis and would need to rerun the experiment before coming to any specific conclusion. The answer above is based on the fact that your hypothesis stated that a certain food would cause the ladybugs to lay more eggs. Is that correct? If I am wrong please tell me your hypothesis and ignore the above response.

Our hypothesis was just "Does different food effect the number of ladybugs?" So, we didn't specify which food.

Then the answer above is correct. However don't forget to put your hypothesis in an " if...then" format and identify your dependent and independent variables. So "If ladybugs are fed different food, then it will effect the number of eggs they lay"

TO ALL MY GROUPS:

Hope you are having a fun Easter break! I know many of you were running your experiments over the break. Please keep me posted. I can not wait to hear the results!!!

**//Here is the Science Fair Paperwork collected for your groups this week.... Brian and Jodi Burda//**

Hello Mrs. Kreide, Our group was wandering if we can cut the excess paper off of our graphs for the science fair board. -Emily,Patricia, and London

Abolutely...whatever makes it look the best!

Hello Mrs.Kreide,
Our group is Anna Quast, Emily de Souza, Jianna Agravante, and Sabina Di Padua. Just wanted to update you on our progress in our project. Once again, our goal is to calculate which orange juice contains more Vitamin C. So far, we have accomplished most of our research. We have received the kit and found everything you mentioned. We are looking forward to this exciting opportunity! :) Thanks for all your help!

Sincerely, Anna, Emily, Jianna, and Sabina :D

Sounds great so good to hear it is going well! The next item due is the individual research papers. How is that going? If you need any resources please let me know! See you at the mentor lunch, Mrs. Kreide

Did you get my message? Jordan Bell

No Jordan I am sorry I did not. What was your message? Mrs. Kreide Reece Gonzalez and I are changing our project. Our now project is based on stomata. The question we are going to answer is : How do gases go in and out of plants? To test our expeirment we are going to rub Vaseline on the top and bottom of leaves on a plant. The one that dies first has the stomata on that side. I'm sorry for the late notice and any inconveinence it brings. Sincerely, Jordan Bell 6th grade

Jordan, That sounds fine but I do have a few questions. What does your research tell you about the location of stomata? Do all plant types and leaves have the stomata in the same location? Are you putting vasoline on both sides of the leaf? Hope you had a great weekend, Mrs. Kreide

Mrs. Kreide, These are the anwers to your questions: The research told us only that the stomata is on the leaves. No, not all plants have the same stomata. We are trying two different kinds of plants. Some leaves have Vaseline on the top, bottom, 1/2 on top and bottom, or none. I also have a few questions. Should we take pictures and notes on the leaves every day or maybe every other day? I am worried that all the info won't fit on the poster board. Also, do we type new research and hypothesis papers on the computer to put on the poster board or do we use the handouts you gave us? Thank you for answering my questions. Jordan Bell 4/4/12

Dear Mrs. Kreide, My plant is not dying at all and it has been over a week since we started. Reece says his plant is dying. I do not know if we should use my plant. What do you think? Jordan Bell 10/5/12

Hi Jordan and Reece, Let me start by answering the questions above first. Take pics twice a week always on the same days like say Tuesday and Saturday so the days are spaced out in the week. Take notes on the plant every other day. Leave a notebook next to the plant with a pencil and write the date and any observations that have changed from the last time you saw the plant. So indicate no change or write any changes. Also note when you water the plant and how much water it receives. Keep it consistent so try to water the same amount the same times each week control your variables. It's always better to have more data and pics because the data can be put into tables and graphs for the board. The pics you can choose which ones best show the results and add them to the board where there is space. You can also display the pics on the table in front of the board if you need more room. Never worry about to much data, it's always better to have more then less. Yes, you will need a new hypothesis and research question for your new topic on the board. Please let me know what you decide so I can review it with you before it goes on the board.

In terms of one plant dying but not the other.... Are they the same type of plant? Is the Vaseline on the same sides of the leaves in both plants? Did both plants have the Vaseline added to the leaves on the same day and time?

Please answer these questions first so we can figure this out together. How exciting to have a science mystery on your hands ...this is what makes science so fun! You get to be the detectives and figure out what happened using your knowledge from the research you wrote.

Great job on the project and hope you are having a fun Easter break ! Mrs. Kreide

I have more answers for your questions. They are not the same kind of plant. We already recorded some info about each one. The Vaseline is on the same sides of the leaves in both plants and it was added at the same day.

Also, I am finally seeing results!! On my plant the leaves with Vaseline are drooping and the untouched ones are not. The only problem is they are not really dying or changing yet. During the break I went on vacation with Reece for 5 days and neither of us checked up on our plants. Is that going to be a problem?

Answer: Glad to hear you are seeing results. To explain why one plant took longer then the other, I would make a table showing the differences between the plants. Also find some research that shows for each type of plant which side their stomata are on. Its ok for the vacation time,but make sure you recorded the results immediately upon return. Pictures would be good as well.

Dear Mrs. Kreide, Thank you for all your help for the individual research paper. I double checked whether the sentence in my essay "The orange juice that needs the //__**least**__// amount of iodine to become oxidized is the orange juice with the __**//most//**__ amount of ascorbic acid" is valid. During my research, I was provided with very useful information, but the way they worded it for this part confused me. I infered that the faster the ascorbic acid's reaction determines whether it had the most Vit. C, but after your very thorough and helpful explanation, I now understand that the one that needs the most iodine to oxidize is the one with most Vit. C. My sentence is now "The orange juice that needs the most amount of iodine to become oxidized is the orange juice with the most amount of ascorbic acid." I will make sure to inform the others. Thank you, Jianna Agravante 6th grade

Sounds great Jianna! Let me know when you guys want to run the lab. Mrs.Kreide

Dear Mrs. Kreide, <span style="font-family: Verdana,Geneva,sans-serif; font-size: 95%;">May we do the experiment on Thursday? Everyone seems to be available. If there is any last minute requirements. We'll let you know. <span style="font-family: Verdana,Geneva,sans-serif; font-size: 95%;">Also we need help figuring out our control and expiremental group. <span style="font-family: Verdana,Geneva,sans-serif; font-size: 95%;">Thank you, <span style="font-family: Verdana,Geneva,sans-serif; font-size: 95%;">Jianna 6th grade

<span style="font-family: Verdana,Geneva,sans-serif; font-size: 95%;">Hi Jianna, <span style="font-family: Verdana,Geneva,sans-serif; font-size: 95%;">Sorry just now saw this question, but I think we addressed it when we spoke at the check in before the break. Just to review the control group should be the frozen concentrate as the other 2 are fresh not frozen. Can't wait to hear the results! What a great topic..the titration will be a super experience as students do not normally perform one until high school chemistry in grades 9 or 10! Go girls!

<span style="font-family: Verdana,Geneva,sans-serif; font-size: 95%;">Dear Mrs. Kreide, <span style="font-family: Verdana,Geneva,sans-serif; font-size: 95%;">I am wondering if we have to bring the models on Wednesday or if we can bring them on Thursday <span style="font-family: Verdana,Geneva,sans-serif; font-size: 95%;">Reece Gonzalez 6th grade
