Density Project

Science Project:
Density

As infants we learn to stack blocks, taking one block and placing it on top of the other, hoping that it will not topple. Just as we learned to build a tower of blocks we can learn to build a stack of liquids. Most liquids, when poured into the same container will mix. However, some liquids do not mix with others so instead they separate into layers. What happens if you drop a small amount of oil into a glass of water? The oil floats to the top. In this experiment we will create a liquid gradient based on density.

Problem:
In this experiment students will learn about density by creating a liquid gradient.

For more engaging science activities, go to Education.com!

Materials:
12 oz. glass (tall)
Water
Honey
Vegetable oil
Rubbing alcohol
Other household liquids
Food coloring (optional)
Measuring cup

Procedure
From you research create a chart of densities among various household liquids. Use the following: water, honey, vegetable oil, and rubbing alcohol. Find more liquids in your home but have an adult make sure it is safe to mix with other liquids.
Based on your chart what has the greatest density? List the liquids in order of decreasing density.
Now you will start building your layers. From your list (most dense to least dense) start pouring the liquids into the glass.
Measure ¼ cup of each liquid and carefully pour the liquid in the center of the glass. Do not pour the liquid down the sides of the glass.
Continue pouring the layers in the center of the glass. The liquids may mix while pouring. Wait a few minutes for the layers to separate before pouring the next layer.
You can add food coloring to the liquids to see the layers better.

Density Summary

Class, this is information we've learned about Density in class. You can click on the pictures to make them bigger. Memorize this information and let me know if you have questions:

PROPERTY	SYMBOL	UNIT
Density	D	g/ml (liquids), g/cm3 (solids)
Mass	m	g
Volume	v	mL (liquids), cm3 (solids)

To calculate the VOLUME of a regular-sized object, remember to multiply it's Length, Width, and Height.  V = L x W x H

And to calculate the MASS of an object, you place the object on a Triple Beam Balance (shown below) and you add up all 3 beams (round to the nearest tenth):

*Remember, you can go to StudyJams and review a lot of videos there on the topic of Matter. After clicking on the link below, click on "See All Topics" and then click on Matter:

StudyJams- Videos on Matter

StudyJams- Video on Mixtures

BrainPop- Compounds and Mixtures

Newton's 3 Laws of Motion-- for classes 702 and 720 ONLY

ASSIGNMENT: For my Honor classes, watch the videos that are shown below over the Winter break. Do the "Test Yourself" and "Quiz" questions that follow the StudyJam videos (you don't have to write them down but it will be wise for you to take notes on the videos). YOU  WILL BE TESTED ON THESE QUESTIONS WHEN YOU RETURN!. Study the content in the videos plus the Forces and Motion packet given to you in class (plus do the 7 questions at the end of the packet and copy the Vocabulary words and definition in your notebook). Do the other reading as well. Here is the list of websites with videos to visit:

1) MakeMeGenius website:
Make Me Genius- Newton-laws-of-motion-for-kids

2) BrainPop:
BrainPop- Newtons Laws of Motion

3) StudyJams: Go to www.studyjams.com, then go to the topic of "Force and Motion" and watch these 4 videos below, plus answer the 'Test Yourself' questions. You don't have to write these questions down, but you will see them in a future test:
a) Force & Motion
b) Newton's First Law: Inertia
c) Newton's Second Law: Acceleration
d) Newton's Third Law: Action & Reaction


**If for some reason you can't see the videos above on StudyJams, here are the links to the same videos on YouTube (the StudyJam videos). It would be a good idea to take notes on these videos since you'll be tested on them:
Newton's First Law: Inertia
Newton's Second Law: Acceleration
Newton's Third Law: Action & Reaction
Force & Motion (not the StudyJams video, but a good one too)


**Here is a website on Newton's 3 Laws of Motion, it's very good and explains this topic very well too. Click here --> Newton's Laws of Motion


Also, check out this song on Newton's 3 Laws:

Finally, here is a video on TeacherTube reviewing the 3 Laws of Motion- Learn Newton's Laws of Motion

Let me know if you have any questions. Enjoy your well-deserved break!

Homework on Fossils, Friday, December 15

Read more about Fossils and the study of paleontology and write a 2 paragraph summary of new facts you learned, in your own words. Click on this link--> ScienceKids- Fossils


Here's a good link on the Principle of superposition --> Prehistoric Planet

Fossils WEBQUEST

Students, go to these websites and copy and answer the questions that follow for each one. First copy the questions down, then look for the answers on the websites. Some are games, some are informational:

1)
