Announcements - 2/27 - 3/1

Important things for you to know:
1) Want some extra credit?   Please help Nick Piotrowski with his science fair project.   Why would I offer extra credit for this?   It is because he has developed a tool to help you concentrate better.   If it works well, we will use it all throughout Quest to help students do better.   
 

Hello,

I am conducting an experiment that aims to improve the concentration and attention span of the subject. So far, I have already seen success, but I need a second phase to confirm my results. 
If you were to join the team, this is what would be expected of you.

First day:

Take a simple memory test, report back the results.

Every day after the first day:

Find a room(preferably where you are alone), and sit in a comfortable position. The session will last 15 minutes and you shouldn't be moving at all in that time period so make sure you are able to stay still. You will begin concentrating on a singular thought, or, on absolutely nothing at all(this option is easier for some). As soon as any internal dialogue, images, thoughts, memories, or any kind of brain activity happens, you must stop the session, regroup, and then begin concentrating again. This should be repeated for the length of the 15 minutes.

Last day:

Take the memory test again, and report back your results.

I really need subjects, so if you could help I would be very appreciative.

Thanks,

Nick

If you choose to join the subject team, then please email me at nickpiotrowski@questforeducationandarts.com, or message my cell at (520) 262 9330

2) Study for an in class quiz scheduled next week.   I am going to expect you to know when to multiply and divide to calculate units and the number of things in a unit.   For example, an owl is 10 things.   7 owls is 70 things and 60 things would be 6 owls.  Not too hard.   You should be able to use a calculator and do that with moles as well.

Homework: 
1) Make cookies.   You can use the recipe on your tasty atomic masses sheet if you like or you can use your own.  Each cookie should have the number of items baked into it that reflect your unit of measure.   Come to class with 2 cookies that contain the number of chips that are the same as your measurement.    Put them in a plastic ziplock bag and staple a paper to the bag that says what your unit of measure was and how many are in it.

2)  Next make more cookies but this time you will use fractions of a unit or multiples of a unit.   Here is an example:
Unit Frog = 6

My cookies might have 1/2 a unit  so 3 chips in them.
My cookies might have 2 of a units so 12 chips in them.

Follow up from class 10/17
Announcements - 10/17- 10/19 
Dear Parents (students, have your parents read this).   Your students have made huge progress in understanding how to apply the scientific method to a real situation.  I was very impressed with ALL of them today. Thank you for sticking with this, even if the writing is hard sometimes.  It will be well worth it because we are doing, not just talking about science.  The doing will make the writing come in time.  You must be able to think about it before you do it and that is the part that has come a long way from the first day of class.
Today we covered:
     
1. The crying onion lab - one of the most important things in science is to do something once, learn how to make it better, and go back and correct it so you get good results.   We will do that next week.  See homework below.

2. Egg tempura lab -  We made paint with 4 different binders.   We now have the paints in a 135 F food dehydrator for a week to see if any of the binders are more heat tolerant that others.
Homework: 
1) ONION LAB - 
  Please write this out and turn it in:
A)    What should we do so that we can make this a better comparison of onion cutting methods?   You should come to class with at least 2 ideas of how to improve this lab so we really know which method works best.

B) You wrote out methods for experiment A and experiment B last week.   Look at what you wrote.   You need to rewrite it and change it to make it say exactly what we did.

Save the results, discussion and conclusion for next week in class after we redo the experiment.

2) Save the measurements part of the lab as a separate stapled paper in your notebook.   We are doing this in class next week so bring it back.

3) Egg tempura lab - Do this on your own and bring it to class to discuss.   You can ask your parents or brothers and sisters for help if something seems unclear.   You can also email Elim or me if you have a question.

      a) Fill in the background questions.   Reread the information at the beginning of the lab if you need to for help.
     b) Above hypothesis, write in a research question.   I am sorry I forgot to put that in for you but you can add it.
     c) Make a hypothesis about which binder will last longer in heat.   Use the internet for help if you need it.  Have a reason.
     d) Try the variables, but do not get frustrated.   If you don't know, save them for class.
     e) Write out all the materials we used.
     f) Write out all the methods in order that we used from day 1 and today.   Don't forget to include crushing the chalk with a mortar and pestle to make pigment and then how we made the different binders mix with the pigments......    Some of them used solvent and others did not.  Make sure you list that.

Write these things on a piece of paper and bring it to class.   DO NOT TURN IT IN YET.   You should not spend more than about 1 hour working on this over the week for most people.

a) Purpose:   What is the purpose of doing an experiment like this?   (One sentence)

b) Research Question:   This is almost like your purpose only stated as a question.   (One question)

c) Background:  Should be about a 4-5 sentence paragraph about onions and why they make you cry.   You should look up an article on the internet and print it off and bring it to class with you.  Use this article to help you write your 4-5 sentences  Next week we will talk about what a sentence at the end of a background should say.  Leave space on your paper to write extra at the end of the background.

d) Hypothesis:   This is an educated guess.   What you you think you will happen when you test different ways and cutting an onion and WHY?   Why is the most important part of this. (One sentence starting with I hypothesize .......)  You must make your hypothesis before testing.

e) Materials:   Think about making a list of things you would use to test this and write them down.

f) Methods: Label this experiment 1 and write down how you would text an onion from video 1.
