Not related to the human body, but because there are so many meteor showers right now I thought you'd enjoy this!
This is the kooky video that we watched in class. You drag a food over to the mouth and watch how it travels down the digestive tract. See what gets broken down and absorbed by the body at each step. How your body digests different foods
*****If you were not in class when we watched the video above, this one will be easier to start with.
Another video about the digestive system http://kidshealth.org/kid/htbw/_bfs_DSmoviesource.html

What does each part do? - move your mouse over each part of the system to see what it is called and what it does.
Today we looked at the make-up of the blood and talked about some of the functions or jobs of the blood in our body.
Cells: There is another video by the same group that sings about the bloodmobile. If you're interested it is also fun.
This is the video we watched in class. It is from the National Geographic and is an overview of some of the systems of the human body.
See if you can correctly place the following: The heart, stomach, liver, small intestine, large intestine, kidneys, lungs. Try any of the other organs and see how you do!
Skeleton - we did not do anything with the skeleton, but here is a game to play. Read the instructions and try to put Mr. Bones back together.
Inclined Planes:
Inclined Plane: use this website to explore how less force is needed with longer ramps.
Which Wedge is Better? - Try the activity with wedges. Which takes more force - a shorter wedge or a longer wedge (you
lengthen and shorten the wedge by dragging the tip of the wedge found in the box under the data table then click the add mass button) ?
Edheads Simple Machines - these are great activities to test your understanding of the simple machines we've been studying. Start in the house, then when you have completed that move to the garage.
If the link above doesn't work, try starting on this page.
Levers:
We have done a lab in class looking at the lever. In your activity you found that by moving the fulcrum closer to the load you needed less force to move the load. Here are some homework activities to further explore the lever, a simple machine.
Try to balance Pic and Harry on the see-saw - be patient as it takes a few seconds for them to sort themselves out!
Check out some of these sites/movies about levers, especially levers in your body.
1. Put the fulcrum (the rock) as close to the load (the rectangular block) as possible. Follow the directions at the site about how to move the fulcrum. Then move the fulcrum away from the load in short steps, collecting at least 5 data points.
2. After you collect your results think about the three questions written in orange:
a. As the fulcrum get farther away from the load, what happens to the force Harry needs to move the block?
b. When you move the fulcrum father away from the block of stone (load) what is the exact distance when Harry can no longer move the block (when the force get too big for him to do the job)?
In class we made a first class lever; a lever where the fulcrum is between the force (effort) and the load. We looked at lots of tools that were different classes/types of levers.
Check out this site about levers.
In a 2nd class lever the load lies between the fulcrum and the force (effort). An example is a wheelbarrow: the load lies between the wheel (fulcrum) and the handles (where the force/effort is applied).
In a 3rd class lever the force/effort is applied between the fulcrum and the load. An example is a broom or a hockey stick.
Friction:
Here's a great summary of lots of ideas about motion. Check out the section on friction and see if it answers any questions for you.
Try these Friction activities:
Change the surface: Try changing the surface to see how it affects the speed of the car. Which surface has the least/most friction? How does the force you use to push the car affect its movement?
Explore motion with this fun activity. You can change the weight of the car, the steepness of the ramp, and introduce extra friction by adding a parachute. Remember to just change one variable at a time!
Here is another friction activity to try. The goal is to put on the brakes in order to stop a vehicle in a traffic jam. In it you have a number of different variables (things you can change in the experiment). You can change the type of vehicle, the speed of the vehicle, the road surface, and the distance at which you apply the brakes.
First try these values: Big Red Truck, 50 miles per hour, Dry Road, 125 feet away. You should stop the car. Now repeat the experiment changing JUST ONE of the values/variables. What are your results? Why can't you change more than one thing at a time?
Bill Nye Friction Video that we started watching in class
If you ask students they will say because it's fun, it's cool, we're studying Egypt in class and Egyptians made mummies.
From the teachers' point of view the real core of the activity is experimental design; fourth graders are now at the stage
where they can design and carry out an experiment more independently.
This is a great scholastic article about Mummifying Pets. Check out the various links
including the digital article and the power point.
*****Mummy Maker - great interactive site that lets you make a mummy. Along the way you make decisions about what to remove and what to leave behind, tools to use,....
There are lots of fun sites about mummification and Ancient Egypt.
*******The Unknown Mummy a really fun adventure. You explore a tomb, collect artifacts and then try to figure out whose tomb you're in!

Article about the Cuyahoga River on fire.
Many commercials were made at the time to try to raise public awareness about the environment. One of the most famous was called "the Crying Indian".
Companies started to realize that people had questions about how they were treating the environment and so they started to make commercials like this one.
Woodsy Owl tried getting message across to kids with ads like these two: Woodsy #1, Woodsy talking about water pollution
HUMAN BODY:
Fun video by They Might Be Giants which introduces DNA and its function in the cell.
Extracting DNA from strawberries - this is a good procedure that we used in Ms. Silverman's class for our extraction. It only calls for one strawberry, but two is better. Also, We think that cheesecloth worked better for step #6 than the coffee filter! After step #8 wait for about 5 minutes before
you try to pick up the DNA.
If you want to explore some more videos about cells here are some fun ones:
this is a cell rap. Don't worry about the names but it gives an idea of what the organelles (remember our organs??) do inside a cell.
Bill Nye the science guy - this is about 20 minutes long and talks about cells

Today we looked at the make-up of the blood and talked about some of the functions or jobs of the blood in our body.
All of this is summed up in a great song by "They Might Be Giants" called The Bloodmobile. Watch it again and see
if you remember all of the functions it mentions. Some of these we will return to in more detail as we continue learning
about the systems that make up our bodies.
Cartoon video about the blood and how the heart works. Don't be too concerned about all of the terms. It's the general idea about the route of the blood that is important.
