Introduction
Here is a fun project you can try with leftover candy you have. You will make some amazing art using nothing but colored candy and hot water—and a little bit of science. Save some of your candy and get started!

Background
Many of the foods we eat are colored with artificial dyes. Some of these dyes will easily dissolve in water. This means that when foods containing the dyes are placed in water, the molecules that make up the dye will break away from the food and start to spread out in the water. The process where molecules spread out like this is called diffusion. The molecules tend to spread from areas where there are a lot of that type of molecule (a high concentration) to areas where there are fewer of that type of molecule (a lower concentration). Eventually the molecules all spread out enough that the concentration is equal everywhere. This is called equilibrium. The molecules, however, do not stop moving completely at that point. They will still bounce around randomly, and diffusion will still occur—but much more slowly.

Turkey Pokey (similar to Hokey Pokey)

• Instead of putting your right arm in and out, put your right wing in and out and

gobble all about.

• Continue with your left wing, your drumstick, your tail feathers and so on.

Freezing Turkey

• Play music while students strut and gobble around the classroom like turkeys.

• Pause music.

• When the music stops, turkeys should freeze in place until music begins again.

Family Volunteer Day

 

Be inspired by the power of helping others! Family Volunteer Day is coming up on Saturday, November 18. This is a day to volunteer as a family, creating deep bonds in your family and with your community. It doesn’t take a lot of time to make a big difference, so  find a local volunteer project.

This is one powerful video.

Rainy Days

When rainy days keep students inside for recess, use the extra time for science! Keep easy-to-do science activities and experiments together with any necessary materials in resealable plastic bags. Then hand them out and have students work with partners to complete the activities. It's a great way to squeeze in a little more science time, plus your students will look forward to indoor recesses.

Chemical Reaction Experiment - Bobbing Raisins

Steps

1.  Pour the carbonated drink into the glass/jar. 2.  Drop the raisins into the glass/jar. What to see what happens to the raisins!!! The bobbing up and down works because the bubbles of carbon dioxide gas in the drink are much less dense than the drink or the raisins. Once the raisins start bobbing up and down, they will continue to rise and fall for about an hour. - Raisins are denser than the carbonated drink, so they will sink. - Gas bubbles attach to the wrinkles on the raisins. - When the raisins are covered with the bubbles they become less dense than the drink, so they start to rise. - The gas bubbles start bursting and then the raisins become denser than the drink, so they sink again.

What a great idea! I saw this on a blog that I was reading.
Jodie Rodriguez shared this image of how she gives her students a white board marker and eraser. Buy a cheap set of hair rollers from the dollar store, cut them in half and slip on the top of a skinny Expo marker! Genius!
