Dry Ice Volcano Cake

Monday, September 4th, 2017

Look at this super cool dry ice volcano cake we had for my son’s natural disasters themed birthday party! I was brainstorming different ways to make a volcano cake, and I’ve never seen this done before, so I thought it would be fun to make. I wasn’t disappointed, and it was fairly easy to make!

Start by baking two cake boxes, for a total of four round cakes. Cool the cakes and place them in the fridge.

Put foil on a square piece of wood or cardboard, and tape the back. Up-end one round cake onto the center of the foil. Grab a chemistry flask and cut a circle with a knife around the edge of the flask. Remove the small circle of cake, and place the flask inside.

Cut circles into the other cakes, and slide them like stacking rings on top of the flask until the entire flask is hidden. If you have a taller flask, you will have to bake more cakes. This will result in a taller volcano.

Place the entire stack in the fridge to cool. Then you are ready to sculpt the volcano. Look at the video demonstration to see how I shaped it:

You can do whatever you want with the scraps of chocolate cake that you cut off the volcano. At this point, you want to place the cake back into the fridge before frosting it.

Frost the cake with chocolate frosting, spinning the cake to get the icing to be smooth. You can cover up any mistakes you made with the icing.

Feel free to poke in plastic palm trees at the bottom of your volcano to add authenticity. This was my husband’s idea, since they were left over from a Hawaiian themed party we did for my daughter years ago. You can buy plastic palm trees at a party store.

Pour hot water into the volcano. Plop dry ice chunks into the volcano. (You can buy dry ice at most grocery stores, and it’s inexpensive.) Now you will see the volcano smoking downward in an incredible way!

Huge List of Hands-on Activities for High School

Monday, March 6th, 2017

hands-on-activities-for-high-school

It’s harder to find hands-on activities for high school than for elementary, but just because you are homeschooling teens doesn’t mean that your day has to be boring and tedious. Everyone learns better by doing–this is true for practical skills like driving and cooking, but also for academic knowledge like science and history. Take a look at our enormous list of fun hands-on activities for high school!

Hands-on High School Science Activities

hands-on-high-school-science

High school sciences naturally lend themselves to hands-on activities because of the lab work required. But as you can see in the following list, you can also have fun with food, field trips, LEGOs, and even comedy to bring your science to life!

Biology

Chemistry

Human Anatomy

Hands-on High School History Activities

hands-on-high-school-history

Each of these activities are applicable to high school ancient history, even though we did many of them before the kids were teens. You would just expect more detail on each of the projects, and maybe a demonstration of the projects in front of a group of peers studying the same time period:

Ancient Egypt

Ancient Greece

Ancient Rome

Middle Ages & Renaissance

Civil War

Modern History

Hands-on High School Geography Activities

hands-on-high-school-geography

Hands-on High School Math Activities

Hands-on Activities for High School Art

hands-on-high-school-art

My high school students did a wonderful job with each of these famous artists, to learn their basic techniques and enjoy the works of the great artists:

I hope you enjoyed this huge list of hands-on activities for high school! Come back to this page often, as I will be adding more posts, including some new high school government posts with video demonstrations!

Elementary Physics Series

We had a great time learning about Elementary Physics, using the book Christian Kids Explore Physics by Bright Ideas Press. Here is a quick index of the different experiments we performed for you on video, to help you as you study this subject.

The first unit of this book is called “The Foundations of Physics.” It describes what physics is all about; how to measure distance, time, temperature, and weight; and it familiarizes us with famous physicists. Here is a demonstration of how we see physics all around us:

The second unit is “Matter.” If you have taken Elementary Chemistry, you can skip these chapters, which are a review of chemistry. If you have not taken Christian Kids Explore Chemistry, here are the experiments from this physics book that you will need:

The third unit is “Mechanics,” where we learned about force, gravity, work, friction, and energy. Here are the video demonstrations we performed to learn about mechanics:

The fourth unit is “Matter in Motion,” where we learned all about motion:

The fourth unit is “Energy in Motion,” where we learned about electromagnetic energy, light, color, heat, and sound:

The last unit is “Electricity and Magnetism.” Here are a couple of experiments that we did for this unit, in order to understand electricity and magnetism:

These fun experiments are from the book Christian Kids Explore Physics by Bright Ideas Press. We really enjoyed studying physics in such a hands-on way. Why not study physics with your own kids by grabbing a copy of this book?

How to Make a Compass

Monday, October 17th, 2016

make-a-compass

Today we will make a compass with a lid, a cork, a needle, and a magnet. This is a simple yet fun experiment to understand magnetism.

First you will want to get a bowl or a lid. I used a peanut butter jar lid because it is large, deep, and plastic. It’s also a great red color. I grabbed a black Sharpie marker and wrote N for north, S for south, E for east, and W for west. I drew a dot in the middle.

Fill the lid with cold water.

Cut a cork in half. Make a groove down the center of the cork like I show you in the video demonstration. If you don’t have a cork, you can use butter or margarine to coat the needle so that it will float.

Now grab a bar magnet and stroke the needle ten times in one direction, using the north pole of the magnet. Insert the needle into the groove of the cork.

Place the needle and cork into the water, and you will notice that it will point to the north pole. Even if you turn the bowl, it will still continue to point in the same direction. And if you pull the needle out of the water and put it backwards, it will spin to align itself to the north pole!

We have loved all the hands-on activities in our book Christian Kids Explore Physics by Bright Ideas Press. Why not pick up a copy of the book and try some of the experiments? Physics has never been so easy to learn!
