Have More Heart - by Evan

I found some links for the blog about the heart.

First, go to this web address and you should be in the video section. Then go to the search bar that is next to Top Stories and type in heart. Now you should find a video that says Rebuilding A Baby’s Heart and that’s the video.

Next, perform open heart surgery at this site!

Finally, take this heart quiz. It covers everything we've learned so far in class!

Happy Valentine's Day - What's in a Heart?

I am excited to be a participant in the Valentine's Day event at CV. An in depth exploration of the symbol of the day - the heart. In my search for more information on this topic, I've been researching the topic and have found some interesting information on a pig's heart. It is quite similar to the human heart, and as such is an excellent way for us to learn more about our heart and how it works. For those interested in preparing and learning more about this heart-felt event, please go to: http://heartlab.robarts.ca/dissect/dissection.html

Happy Valentines Day!

I don't know if I'd be able to pull it off, but I'd love to be able to set something like this up as a demonstration of the concept of advantages pulleys can give us!

Look carefully at the picture. Can anyone tell how much of a mechanical advantage this set up gives? To figure it out, count the number of rope segments are supporting the load.

Here's a game Sophia found that uses the principle of levers we've been learning about in class.

The picture shows that by using leverage people can lift things that are many times our own weight.

What does this picture tell you about how we can use levers to gain a mechanical advantage? What is the relationship between the effort, the load and the fulcrum which allows the load to be lifted?
