AWESOME SCIENCE

Kitchen Lava Lamp

I found this idea online and it is PERFECT to demonstrate density!  The oil floats on the water because it is less dense.  If you add an alkaseltzer tablet it makes bubbles that are less dense than oil and rise to the top carrying drops of water with it.  Once they reach the top and the gas escapes the water sinks back down.  Very cool!  Click HERE to see the video

Add some food colouring to the water!

Diffusion

Using gelatin in petri dishes, a few drops of food colouring, and time you can see how it diffuses from an area of high concentration to an area of low concentration and which colours are quicker to diffuse.  I found the idea HERE

Start                                                                 1 Day                                                              2 days

Beans - 10 days

Our bean plants have grow so quickly!!  In just 10 days most have outgrown their CD cases!!  I had the kids measure them and then label all of the parts of the plant right on the case.  They all got to take them home to transplant and enjoy.  Some winter beans sound YUMMY!!

It also became a major feature on our class bulletin board!

Squash it!

I wanted to see if this would work.  I found the idea using a pumpkin but they are out of season.  Hopefully an acorn squash will work.  Basically you cut it open, shove in some dirt and water, and let it grow!!  Keep posted for our progress.
