Directions for Snow Volcanos
Today we are going to be looking at an explosive subject, volcanos! A volcano is a type of landform (sometimes a mountain) where molten rock erupts through the surface of the Earth. One of the most active volcanoes in the United States is Kīlauea in Hawaii. Kīlauea last erupted on December 20th, 2020. Now let’s create our own volcanos outside in the snow!!
Find a nice snow pile to create your own volcano.
Carve out the top of the volcano.
Place your cup in the hole. (The cup will prevent the snow from melting in the next few steps)
Sprinkle some baking soda into the cup.
Add a drop of dish soap.
Add a few drops of food dye.
With the help of an adult slowly pour in vinegar.
Marvel as the baking soda and vinegar react and pour out of the volcano.
Snow Volcano Vocabulary:
Lava– Molten rock that breaks through the surface of the Earth.
Magma– Is molten rock stored under the surface of the Earth.
Let’s take a look behind the scenes of what happened when you combined the baking soda and vinegar. Both the baking soda and vinegar are made up of different building blocks or elements. When the elements touch each other, they have a reaction. Hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda. One of the results of the reaction is gas bubbles! The bubbles form in the liquid and cause the volcano to fizz!
Today we are going to be looking at physics. Physics is a branch of science that focuses on matter which is anything that takes up space such as air, rocks, and even candy and forces such as push and pull. A person who studies physics is called a physicist. We are going to act as physicist and build a pom-pom launcher.
Tie a knot at the very end of your balloon. The knot should be tied near the mouthpiece.
Working on the other end of your balloon, cut a small piece off.
Stretch your balloon out over your paper tube.
Secure the balloon down with a piece of duct tape.
Now comes the physics part. Place several pom-poms into the tube.
Pull the balloon string back and let go.
Depending on which way you aim the launcher the pom-poms will either fall out or spray everywhere!
Pom-pom Launcher Vocabulary
Matter– Can come in three different states; solid, liquid, and gas.
Force– Cause an object to accelerate, slow down, remain in place, or change shape.
Prediction– To make a guess on what you think will happen.
