EMP Research Hard deadline

When we return from break your research packet and works cited page will be due as a hard deadline (no late work will be accepted).

IMPORTANT!   Before you return to school from winter break send your emp research and internet research template to your own email account.  This will allow you to continue research or to electronically submit your work for the hard deadline.  Alternately if you have a flash drive you may save your work to the flash drive and bring the flash drive with your e- work to school in place of emailing the work.

Odd day classes: you will have ~80 minutes of time in the computer lab on 1/3/11 and your research/wcp hard deadline is 1/5/11.  You will most likely need to spend from 1-2 hours doing research over break.

Even classes: your hard deadline for research/wcp is on 1/4/11; you should finish your research over winter break.

Amnesty Day 12/9/2010

I am offering all students amnesty on ONE SCIENCE assignment from first semester.  I recommend identifying a single project/test assignment (sinker lab and NoS/metrics tests are best if either is not passing) for the biggest affect on your grade.  Test revisits earn .7 points for each point revised and the sinker lab can be completed for all 100 points as graded by the rubric.

Amnesty requirements:
1.  The assignment must be complete
2.  The answers must be correct
3.  Amnesty assignments should require nothing from the teacher, Amnesty only works if you saved the original work and hondouts
4.  Labs & projects graded by a rubric must include the original rubric or copy of the rubric when turned in.  Test revisits for amnesty require you turn in the original test with the amnesty revisions.
5.   In the top margin clearly make an @ symbol to identify you follow directions and want to earn amnesty.

Any amnesty assignment is due by 12:40 PM on December 9th.

Origins 2 HW & Stellar life cycle mini project

Read 821-825 and 805-812 book and conduct internet research for stellar life cycle mini project.


You will only have ~ half the period to illustrate your poster, come prepared with content for the stage diagrams and illustrations.


 
In table groups you will be assigned a possible stellar life cycle to explain through a colored diagram that illustrates and explains the star’s origin (birth) to end point (death) and all of the stages in between.
I will grade your poster (20 pt proj/test) using a SUBJECTIVE Rubric (=I will grade based on what I see and how much I like it!).  The components I will grade (5-0 points each) are as follows:
Content; does your poster explain both visually and through labels the life cycle of your star type?  Describe what is happening to the star in at least 5 stages
Illustration Quality; do the diagrams/drawings/lettering show attention to detail to produce a legible, colorful and neat poster?  I like student generated illustrations best photocopies or print outs won’t earn more than a 3 for this category.  You will not be able to print images from class.
Cooperative Group; did I observe all members working constructively to complete the poster in the very short time frame provided?

Portfoio Assignment Notes

The first week of term three I described the asignment note coversheet assignment for your senior year's graduation portfolio requirements.  The official assignment for credit this year is through your Humanities class due on December 3rd. 

I demonstrated how to find the electronic document for the assignment note coversheet in Ms. Sotomayor's outbox in the Teacher Desk.  I stressed the importance of completing an assignment note cover sheet for an assignment in each of your classes WAY BEFORE 12/3/2010.  The actual written assignment is fairly short and mostly based on your opinion; these will be notes you reference for the senior graduation portfolio.   The tricky part is getting each of your teachers and advisor to sign your assignment note coversheets. 

I am available to sign assignment note coversheets during my office hours, see office hours tab posted on this blog.

I have not given a regular homework assignment for two periods and the next homework assignment won't be until next week.

Odd Classes on Sinker lab and test

The NoS/metric/measurement test is on Monday
Final drafts of the sinker lab were in class on Thursday.  I will accept labs turned in at the start of the period on Monday 11/1/10; they will be considered late, but not for a point deduction.  Homework is to finish any parts of the FD you did not complete during class today.

HOME WORK pass for any complete labs that earn 70 points or more AND are turned in by Friday


I have pasted the analyiss and conclusion section reminders below:

Analysis:  include your calculations and math work for doing the oz to g conversions, relative and percent error.  Make a bar graph that compares each sinker’s posted mass to your measured mass using metric units; make the posted mass one color and the measured mass another color for a two colored bar graph.


Conclusion: (restate the hypothesis, explain how you answered the question or not and compare numeric results to prove or refute your hypothesis, discuss observations as possible sources of errors & impact of error on results and propose a next step and who outside of this science class might care about these lab results or this type of science?)

Dimensional Analysis

Students in the past have often struggled with this crucial science math content.  I have given examples in class and provided students with step by step notes outling how to do dimensional analysis.  If you still do not understand how to do the math; practice is key. 

The following webpage video will go over how to do dimensional analysis with a slightly different take then my notes.  You can also find sample problems by doing a web search for dimensional analysis problems; practice is the best way to learn.

First term progress reports

Students were given detailed progress reports on Monday/Tuesday. I Advised students on how to interpret the progress report and asked them to take it home and share the information with a parent/guardian signature. All classes have a due date of 10/8/10.

no HW for period 1 & 3

The Youth Speaks assembly pre-empted any HW.

Period 5 students need to complete the analysis and conclusion portion of drops 1 (RD or FD)

Question: How many drops of water can a penny hold?

Hypothesis: What is your educated guess to answer the question? No wild guesses. You may compare a single drop NEXT to a penny. Do not start the experiment.

Test: Describe how you will conduct the experiment in a sentence or two

Materials: record every item used for data collection.

Procedures: Record step by step directions of how each material is used in your experiment include a diagram that helps to illustrate complex procedures. I expect your rough drafts to be wrong, make sure the student recording your final draft to turn in includes the actual procedures & diagram that you use.

Data table: have room to include ten trials of data collection. Yes, do the experiment ten times, make sure everyone in your group has an opportunity to collect data by doing the experiment at least two times.

Analysis: show an example of how you calculated the average # of drops for the trial you did and create a table that displays the average number of drops on a penny for all the groups doing the experiment this period. Make a bar graph that compares the # of drops for each trial and the average number of drops.

Conclusion: Do not write the questions or simply answer them. Write the conclusion in paragraph format with complete sentences.
Restate your hypothesis and state how/why it was an educated guess?
Did you answer the question? What was the ave. number of drops a penny held?
Do your results compare to the other tables? Explain.
How might observations during data collection be sources of error? How can you redo your experiment to attain more accurate results?

NoS: Methods of Science question #2-5

Finish questions #2-5 that you copied down during DSW last class.

Methods of Science

The job of a scientist is to observe and explain the natural world. Many observations do not have an obvious explanation, so scientists generate hypotheses, or potential explanations, and test them with experiments.
A good scientist considers all the factors that might be responsible for what he or she observes. Factors that can vary and that we can measure are called variables; examples of variables include temperature, time, water level, number of organisms, and so on. We can investigate the role of a specific variable by keeping all other variables constant while changing the variable we are testing and then observing what happens. This process is called a controlled experiment. For example, we might hypothesize that fish swim slowly at night because the water becomes cool. In a controlled experiment, we would examine the swimming speed of fish at different temperatures. The variable that we change, in this case water temperature, is called the independent variable. The variable that we think is affected by the independent variable, in this case swimming speed, is called the dependent variable. We could also hypothesize that fish swim more slowly at night because it's dark, and we would then examine the influence of light level (an inde¬pendent variable) on swimming speed (the dependent variable).

THINK ABOUT IT

1. Why don't scientists try to test many variables in a single experiment?



WRITING HYPOTHESES

Hypotheses are critical to scientific investigation because they form the bases of our experimental design. Writing good hypotheses can be trickier than you think. We can make a number of statements about fish swimming speed that can be inter¬preted in different ways by changing just a few words. For example, consider the following:
• Fish swam slowly last night.
• Cold temperatures caused fish to swim slowly last night.
• Fish swimming speed is influenced by temperature: at cool nighttime tempera¬tures they swim more slowly than at warmer daytime temperatures.
Each statement includes references to fish swim speed and temperature. How¬ever, each statement has its own meaning and only one can be considered a hypothesis. The first is not a hypothesis because rather than stating an explanation, it simply states two facts: (1) fish swam slowly and (2) it was nighttime what happened (fish swam slowly because it was cool);
it states this explanation as an indisputable fact and is therefore not testable. Only the last statement is a hypothesis. It proposes an explanation for the swim speed of fish at night (temperatures are cooler), and it is testable because we can put fish in water of different temperatures and observe their swim speed.

A good hypothesis clearly states what variable we want to test and predicts it effect. It is not important if your hypothesis turns out to be right or wrong. What matters is that you can test it and draw an appropriate conclusion based on your data.

CONVERTING QUESTIONS TO HYPOTHESES

Below are some questions about the environment. Read them, and identify what variables can be controlled (independent) and what variables will be observed (dependent). Rewrite each question as a hypothesis. Double-underline the independent variable. and single underline the dependent variable. Your hypothesis should clearly state the predicted response of the dependent variable when the independent variable is manipulated. The independent variable can be increased, decreased, or even removed during the experiment.

For example, the question, "Is the rate at which a substance gains or loses heat related to its density?" can be restated as the hypothesis, "The more dense substance is, the faster it will gain heat." Other possibilities are equally valid for example, "the more dense a substance is, the more slowly it will gain heat,"
2. Question: How does the amount of energy that hits the Earth in the form of light rays relate to the angle at which those rays strike (latitude)?

3. Question: Does rainfall influence the distribution of different biomes such deserts, grasslands, and forests? '

4. Question: Does the extinction of a predator species result in a faster rate population growth in the prey species?

5. Question: Is plant cover related to soil erosion?
