As I mentioned in class today, we are going to have a short HW Check tomorrow. What is that? It is basically a short 6-8 question quiz over the work we have been doing this week- Kearny by Equation, Ox Expressions and Balancing Chemical Equations. You’ll have to write some algebraic expressions for some given statements and your have to write some statements for the given algebraic expressions. For example, MF is the total number of men in a family. Or what does the .4H in the Kearny equation mean.
You will also see some chem equations where you need to balance the number of atoms of an element on one side with the same number of atoms of that element on the other side. If you need some help on this, check out ck12.org the Basic Chemistry book and click on Chemical Reactions, and see 5.2 chemical equations. Remember, to count the number of atoms by multiplying the coefficient by the subscript for the element.
Other than getting prepared for that, you should be doing some research on your Mad Scientist Topic Research. Study the topics related to your experiment by researching the topics I outlined for you and your partner, and look on ck12.org for some background on the chemistry topic.
More research tomorrow!
We have been working on the POW #2: Around the Horn this week and hopefully, you are understanding and working through the complexities of solving it. You should be taking some careful notes to use in your writeup of this problem which is DUE this Friday.
Remember, that this is a project grade so it deserves your attention, thoughtful writing, and thoroughness. What I mean is that I expect you to put together a writeup that hits the following:
- Follow the Format with Bolding Subheadings: Problem Statement, Process, Solution, Extensions, and Evaluation.
- Make sure to address both scenarios for this problem. Scenario #1: no boats had sailed before you Scenario #2: boat have been sailing before you. You should have a different answer for each scenario.
- Write, Write, Write….a few sentences for each section will not be satisfactory. The Process and Solution section should be longer.
- Write it as if you were writing it to someone who has never seen the problem before.
- Be clear and explain your reasoning with facts to support your THINKING
- Make sure to explain the Why of your Thinking
- Reference or attach any diagrams, scratch work, tables or math you used to help you solve the problem.
- Make sure to list the Assumptions necessary to reaching your solution…for example, like the one that we said that all boats must sail at the same rate and on the same timetable.
- The extensions section is for you to provide other ways of solving or other possible answers that were presented in class.
- The Evaluation section is for you to write a short paragraph about what you learned about doing math from the problem, reflect on what was done in class that might have helped you with the problem, and things you did that supported your thinking.
The POW is all about you articulating (that means communicating) your THINKING and PROBLEM SOLVING SKILLS.
We are off on planning our Mad Science Expo….This week we are in Phase II- the Research & Design Phase of the project. Here is a link to the project: Mad Scientist Project. So, you and your partner should be researching, brainstorming and thinking about interesting questions our 2nd graders had about the world around them….You need to come up with 3 possible ideas for your Mad Science Expo. You’ll need these by Wednesday as we will decide who does what!
Tonight for homework, you need to have read through and sketched out a few ideas on how to solve the Around the World POW….it will be due on Friday and we will go over tomorrow. Lastly, the Periodic Table questions are due on Thursday….(many have already turned in). This is the last of the four foundation chemistry questions that we have been working on.
But, I want you to push your chemistry knowledge deeper so go on to ck12 and pick a chapter or two to read and answer questions for extra credit. Do more than what you think you can….
You know everyday counts! What we do each day in class, each assignment, and every problem you push yourself to solve and figure out contributes to your full understanding in the end. We have a test over the Overland Trail on Friday and time to earn your first Yellow Belt of this unit. As per my last post, the topics or assignments are clear but here are some other possible questions:
- Create a family based on some constraints that I give you and explain why it works
- Read a constraint and turn into a mathematical sentence (know your inequalities??)
- Evaluate a formula for a Family constraints and tell me the age of child, mother, grandmother.
- What could be the largest family you could create based on some constraints that I give you.
- Scenario problem….look at some data and put together an argument making a claim based on 3 pieces of evidence.
You will do some math calculation but more than anything, you’ll communicate (articulate) your thinking by writing!
Lastly, your Reaction Know How questions are due Friday so go to http://www.chem4kids.com
I also shared with you a google doc on chemical equations for you to read and answer questions on chemical equations….it is an optional assignment.
Also, due Friday is Balancing Chemical Equations!!
So much going on but it is the pace that you must become more accustomed to now that you are getting ever so close to high school!
Study Hard and hope you read this DP tomorrow….I just might post a question or two for the test on Friday???
Students or shall I say, Overland Trail Pioneers!
Your first adventure awaits you as you prepare to embark on the Westward expansion…no, you will not be traveling anywhere but this Friday…you will have your first Test (kinda like the pioneers had as they faced the ardurous journey West…bears, weather, etc). Therefore, it is important to get ready for Friday’s test which will cover the basics of what we have been working through in the Overland Trail. You will basically see the same type of problems that we have completed with different constraints, numbers…just to see how you are understanding so far. Of course, you’ll have to write to explain your thinking detailing in words and using visuals/diagrams or mathematical calculations to serve as evidence of your thinking. Here is what you should review and rework if necessary:
1) Family Design- looking at the constraints and come up with a family based on those constraints (they are inequalities)
2) Hats for Families- making the smallest and largest possible family within the constraint.
3) Family Constraints- reading the equation and understanding in terms of another. What does the variable represent and how is it used to express the age of other people ‘in terms’ of that variable.
4) Search for Dry Trails- make an argument given a set of data and make a claim and support it with at least 3 features of the data.
We will be moving on to the other tasks moving forward in this unit so it is up to you to start studying! My recommendation is to test yourself by reworking the problems itself! Need help or clarification…see me afterschool!
Lastly, for HW tonight……Complete the Planning for the Journey by calculating your total budget ($10/person * How many people in your family). Then make a list of all the things you will buy and track how much you will buy and how much you spend! Have it ready for class tomorrow!
Below are a few things I need you to do- all to benefit class and your learning! (all of this I sent to you in your email as well)….this is your Homework Tonight!
First: Take this Survey for me. It is anonymous. https://www.surveymonkey.com/s/D27G6CL
Second, Sign up on ck-12 Flexbooks. This will be an online learning resource we will be using this year. Instructions are below as well in your email.
Third, please complete Family Constraints….you did #1 for HW last night now, finish it off by completing all of #2. Know how to construct an equation of the ages as it relates (or in terms of) the child’s age.

Isn’t it horrible??? A virus that causes early balding….Yikes!! No, not really…you know what it was? We did the classic chemical reaction of Sodium Bicarbonate and Acetic Acid. Tomorrow, we’ll see if you can put your deductive thinking skills to test to narrow down and isolate the original carriers. Push you thinking and examine your lists about who could have traded with whom and been the original carrier.
Your HW for tonight:
1) Hats for Families Problem- write a paragraph clearly defining how you can create the MINIMUM number of people and the MAXIMUM number of people in your family. You have to carefully link your reasoning to the constraints listed in the Family constraints handout (its what you used to make your family out of). Make your case and prove your thinking to me!! We had some great discussions in class today.
2) Viral Reaction- look at your list of Positive & Negative carriers and make a 2-3 sentence hypothesis on who you think the original carrier is.
Tomorrow, more work on Viral Reaction and what makes reactions possible!
