Flower Pot Gifts

We LOVE our teachers!! So yesterday my sister and I went to Jo Ann Fabric and Crafts trying to come up with a clever gift that the kids could help put together quickly. And like most of my brilliant ideas, it actually came from my sister.

My Materials : 
     The terracotta pots, $0.69 each 
     Acrylic paints hidden in my storage area 
     Pinwheels, $1.50 from Jo Ann.
     A bag of individually wrapped mints from the grocery $1.00

I had the kids paint the rims of the terracotta pots, filled the pot with candy, stuck the pinwheel in it and TA DA!! Instant teacher gift. This would also be a good gift for Grandma and Grandpa, but since they read my blog, I will have to come up with something else. 

Grade: B

Making a Wreath

I have nothing to hang on my front door this time of year.  I decided to attempt to hang a natural wreath on my front door.  I live in the North East and it is cold enough this time of year to keep a natural wreath on your door for about a month until it starts falling apart. 
I have this beautiful blue spruce in the back yard so I took some clippings from the bottom of the tree, not the middle or the top. You don't want to make the tree ugly, you still have to look at it.
Materials: Green florist wire, branch clippers, wire cutters and an evergreen tree. The florist wire is around 2 or 3 dollars.
 I cut the florist wire into 12 - 5 inch strips. I used clippers to trim down the branches to be the length  of my elbow to my wrist. Anything left over, I cut off the main branch so I could have fill in pieces. I laid down the main branches and tied them together from tip to end, securing them in two places, on each branch with the florist wire. 

Unfortunately, the darn thing was floppy. Apparently the wired branches will not hold a circle when picked it up. I looked around the garage for something with a circle shape... and found a hula hoop that I made last year from an irrigation hose. I wrapped the florist wire around the hula-hoop and the branches to secure the floppy wreath on the hula-hoop. I shoved in the filler branches in any place that looked thin, put a bow on it and TA DA! 

My daughter was a little annoyed to see her hula-hoop on the front door. Now I realize that I could have used a wire hanger and shaped it into a circle instead of using her hula-hoop. Next time I will give that a try. Another thing I would have done differently is use gloves, I scratched the heck out of my hands and forearms.

Grade: A 

Skill Level: Low

Difficulty Level: Easy

Frustration Level: Low

Price: $ (Florist wire is only around 3 dollars)

The Third Grade Science Fair

I can't seem to do anything low key.  Its always got to go well beyond expectations. Is there a disorder in the DSM that describes this behavior? 

This year I was so excited about doing our first science fair in March, I made my daughter choose her topic in January so I could get started thinking about it. She picked The nervous system because of this schoolhouse rock video. 

So I pulled together 5 age-appropriate Neuroscience experiments that an 8 year old could perform and understand from the internet. Thanks for the help University of Washington, what a wonderful website!  My sister-in-law also gave me some ideas because she did a model of the peripheral nervous system with string and cardboard when she was a kid using yarn as the peripheral nerves. I went over all of these ideas with my child and she had some ideas, such as "What if we could make the peripheral nervous system light up?"


I went through the toy-box to examine everything we have that lit up. I found some toys made with fiber optic lights. BINGO! but they were only a couple of inches and my daughter wanted it to be about 3 feet high so I searched the internet and found a website that sold fiber-optic side-glow cable by the foot.  The great thing about fiber fiber-optic side-glow cable is that you just shine a light on it and it glows.

PROBLEM: The bad thing is that for you to see the cable glow, it has to be about two times brighter than the room.

SOLUTION: I went to the UPS store and bought a box 3 feet high and spray painted the inside black. My daughter wanted to also spray it with black glitter spray for that extra pizzazz.

My daughter drew an outline of a kid body inside the black glitter box with white chalk, punched a hole in the top of the box where the brain would go and pushed in the fiber-optic side-glow cable and slid it into place.

PROBLEM: When we went to tape in the fiber-optic side-glow cable on the painted glitter box it would not stick. DUH. I have worked with enough glitter stuff enough to know that scotch tape will not stick to a glittered surface.

SOLUTION: I used wires to put everything in place. At this point she could not help and now it was more my project than it was hers. Who knew that was going to happen? Everyone probably.

It was very difficult to punch that wire though the box. I had to use a pin to start it then fish the wire through. It took forever and that pinchy wire hurt my hands.

PROBLEM:  We had to make a brain out of clay and some how attach it on top of the fiber-optic cable entering the box.

SOLUTION: I cut a spongy ball in half and molded the clay around it. Then rolled some clay into a long skinny worm and put that all around. I pushed that awful wire though the spongy half ball, I pushed the wire through the cardboard box and Viola! Brains! I put our lizard light on top of  the box where the the cable  was and it looked great. Of course I used energy efficient light bulbs because they are low heat and I didn't want to light the box on fire or melt the fiber-optic cable.

My daughter has these really great light up multi color blinking shoelaces. We decided to wrap them around the spine to make the central nervous system a little more special.

PROBLEM: My daughter didn't like the fact that our peripheral nerve model was white. She wanted colorful nerves.

SOLUTION: I put plastic Easter egg halfs (pink, yellow, orange, purple) on top of the fiber-optic cable and wow!!! It really gave it that extra kick.

This was probably enough for the science fair, but of course, I still wanted her to perform the 5 experiments on the kids to explain how the nervous system works. We studied the the different functions of the nervous system. I typed out the terms that were the most important and I had her define them in her own words, incomplete sentences and all.


#1 Visual Illusions.

This shows how you can trick your central nervous system.   Read the half covered words at the top of my poster. What do they say? Lift the paper and see what it really says. Our eyes see the half letters then sends a message is sent to our brains then the brain fills in the part you do not see.

#2 Two points of Discrimination Test

This shows how sensitive your nerves are on different parts of your body.  Take 2 toothpicks and put them close together on the tip of your finger, does it feel like there are 2 or one toothpicks? Move them farther apart, does it feel like two or one toothpicks? Repeat on your elbow.  Can you tell the difference between one or two toothpicks on your elbow? 

#3 Autonomic vs. Somatic Blink Experiment

This shows how you can control blinking (somatic) and how you blink automatically (autonomic).  Control the movement of your eyes by blinking.   Have a friend clap their hands in front of your face and you will automatically blink without even thinking about it.

#4: Digestion Response

This shows how the parasympathetic nervous system works. When you are at rest, your body digests your food. Smell the mystery box. Does that make your mouth water?  Saliva is part of digestion and the smell of oranges causes your parasympathetic system to respond by making more saliva. Smell the other mystery box, does this give you the same reaction?

#5: Flight or Fight Response and Heart Rate
(FOR 3rd graders and up) This shows how our sympathetic nervous system reacts.  Watch the movie; does your heart rate go up? If it does, I caused you to have a sympathetic response.

The number 5 experiment was a big hit with the classmates. I thought I was going to get in big trouble but most of the kids were familiar with this youtube video already.

Now if there was a prize for this Science Fair, we would have won. But it was only for participation. That doesn't matter, I enjoyed every second and I can't wait until next year's science fair.
