13 Days of Halloween: The Magic Bottle

https://www.teacherspayteachers.com/Store/Kimberly-Scott-Science


We made it to Day 13.  13 blogs in 13 days has kept me busy.  I have had a lot of fun.  Most of my Halloween decorations are up.  More will go up just before Halloween.  Halloween is such a fun night.  This year I will be hosting a pot luck on Halloween and then all the kids can head out for trick-or-treating.  My husband takes my kids out and I stay home to scare the kids. 

Here is a fun science activity.  Experience a little magic on Halloween.  I wouldn't say it is Halloween themed, but it is a good trick.

This makes fun station activities.  The students start with the first station and then make there way through.  The bottles are inexpensive and they take them home when finished.

Thank you for participating in the 13 Days of Halloween.

13 Days of Halloween: Flubber Fun



Years ago I made a slime recipe with my kids using psyllium husk.  The name brand is Meta Mucil.  My kids had a blast with it.  It is a little different than gak and slime, but lots of fun.  I call it flubber because it reminded us of the movie Flubber.  We actually watched the movie Flubber the day we made it.

Flubber Ingredients
100% psyllium Husk (Meta Mucil)  It can be different flavors or plain.
Water
Measuring spoon and cup
Pot
Whisk
Plate

Flubber Directions
1.  Pour 1 cup of water into the pot.
2.  Turn the stove on high.
3.  Add 1tbs.  psyllium husk.
4.  Using the whisk mix well.
5.  Continue cooking on high and stirring for 8-12 minutes.  The longer you cook it the thicker it gets.  You may want to play around with the cook time to see how you like it best.
6.  Place on a heat safe plate to cool.

Important:  It will be very hot.  It will bubble up so you must stir it constantly.  You will see the water evaporating from it.  Even though some will stick to the pan, clean up was easy.  Just keep stirring. 

I used the orange flavored Meta Mucil.  It made it this strange color.  When it was finish it looked like raw chicken.  You could try other flavors or add some food coloring.

This can also be made in the microwave.   You heat it for 5 minutes.  The only problem with that is you have to stir it every 30 seconds or it will boil over.  The container also gets very hot.  I like making it on the stove.

Add some spiders for a Halloween theme.  This is also great to put in a mystery box for students to touch.

13 Days of Halloween: Harry Potter Theme



Harry Potter is perfect for Halloween.  Here are some great ways to integrate the theme into your home or classroom.

Platform 9 3/4th Door



This was very easy to do.  I used a red plastic table cloth.  Take a black permanent marker and draw bricks. I printed out a 9 3/4 sign and glued it to the top.  I made a slit for the kids to walk through.  Perfect for a classroom door.

Harry Potter Cupcakes

You could make your own cupcakes, but I bought store made.  Melt chocolate and dip it onto ice cream cones.  Let it dry and place them on top of the frosting.  Use red gel frosting to make a lightening bolt on the cones.  They make perfect wizard hats.

Honey Dukes Candy store


My son was in charge of the candy store.  We picked out candy and he came up with the names.  You could search the book for items too.  Chocoballs, Salt Water Taffy, Exploding Bon Bons, Droobles Best Blowing Gum, Acid Pops


 Keep decorations simple.  Decorate with black balloons.  Place owl cutouts all over.  You could even pull out your Halloween d├ęcor.  Ghosts work great.  This shows the table set up for a potions class.  For a classroom I would have simple station activities.

13 Days of Halloween: Dry Ice



Today I am teaching a lesson with dry ice.  A perfect day to blog and create some videos while I set up.  I hope you are enjoying the 13 Days of Halloween.


What is it?

Dry ice is the solid from of carbon dioxide.  Carbon dioxide is most commonly found as a gas.  It is the gas we exhale when breathing and the gas plants take in for photosynthesis.  The chemical formula for carbon dioxide is CO2.   Carbon dioxide gas is a heavier gas.  It will tend to float along the ground. 

What is different about dry ice than frozen water?

The first difference is that dry ice is much colder than frozen water.  Water freezes at 0°C.  Carbon Dioxide freezes at –78.5°C.  This is why you must wear protective gloves.  It is so cold it will burn your skin.  The second difference is how they melt.  Water will always melt from a solid to a liquid and then evaporate into water vapor.  Dry ice does not melt.  It goes through a process called sublimation.  Sublimation is when a solid directly changes into a gas.  It skips the liquid phase.  As soon as you take out a piece of dry ice it is sublimating into a gas.  This gas is very cold.  When the CO2 gas touches the air it causes the water vapor in the air to condense to form fog.  The fog you see is not CO2, but liquid water.

Safety Precautions

Never, ever touch dry ice.  It is so cold it will severely burn your skin.  You must wear oven mitts, thick gloves, or use tongs to handle dry ice.  The room should be well ventilated.  When the dry ice sublimates to CO2 the gas can build up in the room.  You don’t want to breath in too much CO2.  Never put dry ice in a sealed container because the container will explode.  Always wear safety goggles when working with dry ice.

Dry is lots of fun and a great way to explore the properties of solids, liquids, and gasses.

Try Dry Ice in Different Temperature Water.

Now Add Soap to the Bubbling Water.

I buy dry ice at a local grocery store.  You may need to search for a place that produces dry ice.  Searching on-line should help you find some.

  Are you looking to have students create investigations.  These investigations journals will help them through the process.  Perfect for classrooms and science fairs.

13 Days of Halloween: Burping Bottle

I was teaching a lesson on tornado tubes and wanted to show different ways to use them.  I saw directions for a burping bottle, but didn't have the exact supplies.  I looked at it and realized a tornado tube could work perfectly.  The students really enjoyed it.

Here is the original burping bottle I created.  I also switched it up for Halloween.  Make sure to read the whole blog.  If you don't have a tornado tube that is okay.  I have a solution for that too.

video
What is happening?   Matter can not occupy the same space.  The bottom bottle is full of air.  The water can not go into the bottle unless some air comes out.  A bubble of air comes up the straw and then  water goes down the straw into the bottle.  Sometimes it starts on its own and other times you have to give the bottle a little squeeze to get it going.  It will continue to "burp" until the water level is the same height of the straw.  The students will enjoy seeing how high the burp goes.

Heres I how I made it.

Place a straw through the hole in the tornado tube.  Fill clay around the straw on both sides of the tube.  It must be air tight.  Make sure the straw does not get squished.  Cut the top bottle so it is a funnel.  Screw both bottles to the tornado tube.  Stand it upright.  Pour water into the top bottle.  Make sure it is over the height of the straw.  It might start on its own or give the bottle a little squeeze.


If you don't have a tornado tube you can use a potato.  Yes, I just said potato.  Cover your finger over one end of the straw.  This will make it easier to poke through the potato.  Use a small potato or cut a piece. Stab the straw through the potato.  Remove the potato piece from inside the straw.  Using your muscles screw the potato to the openings of each bottle.  This is tricky, but you will get an air tight seal.   Add water and use it just like the tornado tube burping bottle.


Create a Halloween Twist.

Add oil into the bottom bottle and colored water into the top.  As the water enters the bottle students will see a bubbling concoction.

13 Days of Halloween: Color Changing Liquid



Here is a great Chemistry trick to get your students guessing.

video


Supplies:
4 or more tall clear containers
Red Cabbage Juice Extract (See directions below)
Water
Baking Soda
Epson Salt or other salts
Lemon Juice
Rubbing Alcohol

Other substances to try:  vinegar, baking powder, apple juice, nail polish remover.  Always make sure the liquids or powders you choose can be mixed with water.  I try to use common kitchen items.

Please wear safety goggles.

How to Make Red Cabbage Juice Extract


Red cabbage juice is an acid/base indicator.  This means it will change color in the presence of an acid or a base.  It will turn red/pink in the presence of an acid and green in a base.  There are many colors in between.  The more acidic the more pink.  The more basic the more green.

Purchase a red cabbage at the store.  They are about $0.99 a pound.  I paid $1.50 for a small one.  Take off a bunch of the leaves and place them in a pot.  Cover the pot with liquid.  Bring water to a boil and boil about 15 minutes or so.   You want to boil it until the color is pretty much out of the leaves.  The liquid should be a nice purple color.  Allow to cool and then pour the liquid into a container.  One cabbage will make more than you need.  I will make a batch and freeze some for
future use.


 Set-up for the Students. 

Make sure they don't see you do this part.

Place the tall containers on a table in front of where your class will sit.  Fill each with about 200ml of liquid.  You want to make sure there is enough room left for adding red cabbage juice.
Place the following in each container:
Container 1:  plain water
Container 2:  Add a teaspoon of baking soda and stir until dissolved
Container 3:  Add a teaspoon of Epson salt or another salt.  Stir until dissolved.
Container 4:  Add a teaspoon of lemon juice.  Stir.
Container 5:  Add a teaspoon of rubbing alcohol.  Stir
Other ideas could be vinegar which is a strong acid or baking powder which is a base.  Anything that will dissolve clear so that it looks like water should be in all of the containers.

Demonstrating for the Students

Make sure they can see the containers.  Tell them you are going to pour in a special liquid into the tall containers.  Don't tell them anything else.  Quietly pour them into each container until they change colors or are pretty full.  Ask the students what happened and why.  They are sure to be surprised. 

Here are some great links on acids and bases to help with explanations.

13 Days of Halloween: Classroom Slime Recipe



We have made it to Day 5 of the 13 Days of Halloween.

Here is a classroom recipe for slime.  I have it all measured out for a class of 25-30 students.  Directions are written to create 2 solutions.  The students then measure out the two solutions and mix them together.  It makes it so much easier.

You can use regular white glue or try clear glue. 

For a Halloween twist add plastic spiders, glitter, or glow powder.

Just click the image to get the free download.

13 Days of Halloween Glow Stick Fun



There are so many great resources out their for Halloween and Autumn.  Below is one of my favorites.  Continue reading to find a Linky Party to post your own or check out other resources too.

This is one of my favorites.  Kids love glow sticks, but do they know how they work?  Students will follow the scientific method to answer the question: 

Does the temperature affect the brightness of a glow stick?

This is a great way to introduce students to the scientific method.  The investigation comes in 3 grade levels.  Each level builds on the other.  It also makes it possible to teach the lesson at the same time. I like teaching it at Halloween because most kids trick-or-treat with glow sticks.  Because the chemicals are contained in the stick the only mess is some water and ice.  It also shows that molecules speed increases with heat.  A memorable scientific experience for students.  Also great for the classroom party.

13 Days of Halloween: Create a Headless Horseman Costume



We love homemade costumes at my house.  Last year my 8 year old son decided to be a headless horseman.  He wanted to wear the pumpkin head.  We searched Pinterest for lots of ideas.  It took some time to map it out, but once we went to the fabric store it became clear what we wanted to do.

Here is how we did it.

We bought a craft pumpkin at the fabric store.  Some are already hollow.  This one was not hollow, but it looked more real than the others.  You also have to make sure it will fit your child's head.  Make sure to bring them to the store with you.  Or make sure it fits your head. 
This is a great teacher costume.

Digging it out took a while, but it wasn't as tough as I thought.  This pumpkin was full of Styrofoam balls.  I had the vacuum ready for the mess.  I took my time.  Start with a small hole and slowly cut it out bigger.  I constantly tested it on my sons head.  When it was done we carved a circle the size of his head in the top.  This helped to make it a tighter fit.   He also wore a hat to help it stay still.  If you can find a hollow pumpkin I recommend using that.


 Next we drew out the pattern and carved it out.  In this picture you can also see we glued fabric over the eyes.  The Styrofoam balls kept falling out.  We sprayed the inside with lots of Clear Coating.  This helped reinforce the foam.





 The next step is to paint the inside edges of the eyes, nose, and mouth.  Paint works best, but a permanent marker works too.  We used a marker for any touch ups.  My son chipped one of the teeth, so the marker came in handy.
Here is the finished mask.  The fabric over the eyes really helped. 
My son looked through the mouth.

We already had a black cape.  I shortened it for him.  He wore black pants, shirt and shoes.  We had the red vest left over from a pirate costume.  It turned out so well.
