Mr. Edmonds on Mass, Weight, and Density

This guy is AWESOME!  He makes me laugh and makes me sing!!  Singalong to Mr. Edmonds to understand more........ Singalong!!!

Eureka!

A naked guy running through the streets of ancient Greece!

Watch the video on Archimedes and work on the Eureka lab. 

 

Mass of Classroom Animals

Too Many Rats for Breakfast

Soon we'll be getting some 'baseline' data on the classroom animals.  To prepare for this, click on fat cat and it will take you to a data table.  Either copy the table in your lab journal or just print it out and bring it to class.

Either way, make sure you have the table with you when you come to science class.

Mass Tutorial

Click on the picture to watch Tim and Moby on mass, volume, and density. It should help with your homework!

Quick Check - Reading a Graduated Cylinder

Just a quick check to see if you're ready to move on!  Look at the level of water in each graduated cylinder and write your answers on the scrap paper at your station.  You can easily enlarge the image in order to see it better.

Quick Check Graduated Cylinder

Look at the level of liquid in the graduated cylinder.  In the form below the picture, write your answer for each cylinder.

LET'S GET PRECISE!

In our recent labs we've continued to work on precision. From the 3cm ruler activity to the Rainbow Lab.... it's all about being precise.   But why?? Why is it so important to be precise?  Think about it!  So many reasons - in science... and in life actually.  Check out this video of Desean Jackson - he's talking about precision in football!  (Of course, I have no idea who Desean Jackson is... but Mr. Emerson shared this with me.  I guess he's some sort of famous wide receiver eh?)  PRECISION!  Skip to 2:05 to get to the precision part if you wish.



REFLECTION..... Create a blog post and do the following:
1) Label your post properly for science

2) Go to creative commons and find a picture of someone being really precise

3) Write a strong explanation of why precision is an important skill for science and life

4) Include an example from outside of school where being precise is important.  This can be from you or from an adult job or experience you or someone you know has had.

Observation and Inference Quick Check

Volume of Liquids

How would you find out the amount of coffee that is in this mug?  How would you measure it?

Today we'll learn how to accurately Read a Graduated Cylinder and work on a lab to find out just how accurate you are!

Observation, Inference, and Precision in Measurement!

Today in class you went over your balloon observations - qualitative and quantitative.  Fun eh?  You also learned a new concept - Inference - making sense of the observations; an explanation of what that observation means.  For example, you saw bubbles as soon as you mixed the vinegar and baking soda. From that you would infer that a chemical reaction is happening and a gas is being produced.  Get it?  Start working on your observation/inference experiments this week at home.  They are due Friday for class C and E.  Monday for classes B,D,F. 

Practice precision in measuring by visiting the following website and working through it. You need to scroll toward the bottom of the site to reach the interactive measurement slides.  See how well you can do.   Click here for the Interactive Meausurement Website 

If you finish that, put in your ear buds and watch Bill Nye's clip on measurement
