Quiz scores are in Teacherease

Hope you all are having a great weekend! I saw a lot of you out this weekend, either at Arts Walk on Friday night, or at the soccer game on Saturday, or at the procession of the species. What a busy weekend!

I have been busy grading all your quizzes and catching up with all the papers from before conference week. As of now all science grades are in teacherease. There are a few of you with missing assignments still though. Please turn them in as soon as possible, or talk to me.

A lot of you told me that you thought the density quiz was easy. But only 3 6th graders got 100%. The third period average was 84.8% and 4th period 88.1%. I'll hand back a big stack of papers tomorrow, but if you want to see your score and read the comments I wrote you then check teacherease now.

Independent Science Research Project

The purpose of this assignment is to give you an opportunity to research a science topic that you are interested in. The topic must be science related and it must be something you can find information on from the Internet and in books. You will present the findings of your research project in a 5 minute presentation in class. You will also turn in a one-page reflective essay on the day of your presentation.

Proposal (10 points):  5/1/12

Type up a document that includes:

o   The area of science.

o   The topic to be investigated.

o   Why you chose that topic, and what you hope to learn.

o   What you will do for the presentation.

Density Quiz Review

You will be assessed in the following areas on the Density quiz on Friday.

- How to calculate the volume of a cube and rectangular prism using a formula.

- How to calculate the volume of an object using displacement.

- How to calculate the volume of an object that has a density of less than 1 g/ml.

- What the density of an object is if it float or sinks.

- How to measure the mass of an object.

- Understanding the relationship between the units, g, cm3, mL, and g/mL, g/cm3/.

- How to calculate the density of an object given its mass and volume.

Density Quiz Friday

Hey 6th graders. Hope you had fun during switch day today! Conferences are all this week, so the class schedule is a little but different. Tomorrow you wont have science class, but the whole 6th grade will have a fun hour long period with me where we will play a game, then we have class on Wednesday and Friday. On Wednesday we will finish reviewing density, and you will get more details about your Independent Science Research Project. Then on Friday we will have a small quiz covering density. I'm grading your density lab questions now, and they are pretty good for the most part. Here are some photos I took during the density lab we did last week.

Density Lab Questions

Nice work on the density lab today, nearly everyone managed to calculate the density of 10 different items.
The homework for Friday is to create a data table and answer the questions below. The data table of your results should be created on a spreadsheet (such as excel) and it should include the object name, the mass, the volume and the density. List at least 10 different objects. Be sure to include correct units for mass, volume and density.

Also please answer the following questions.

1. Which object had the greatest density, what was its density?
2. Which object had the least density, what was its density?
3. What is the problem with measuring the displacement in water of objects that have a volume of less than 1g/ml?
4. What were possible sources of error in your measurements?
5. How could you improve upon this experiment?
6. How is density measured? Can it be measured directly?
7. Which of the two variables (mass or volume) has a greater influence on whether an object sinks or floats.

This assignment is due on Friday, so if you have any questions about it email me or ask me in class on Thursday.
