How are Mountains Made?

How are Mountains Made

Have your kids ever asked you “How are mountains made?” ?  My oldest has asked before, although what she was calling a mountain at the time was really just a big hill but to her it was a mountain.  I tried to explain to her about plate tectonics and convergent boundaries but well lets be honest she is only six and that is a lot for a six year old to understand.  So I thought why not show her with a fun science experiment that she could even eat at the end (my girls at totally motivated by yummy treats!).

I got the idea for this experiment from my Sis who teaches Science in High School.  She actually did this experiment with her students and said that they all really enjoyed it (and yes she let them eat it too after they were done).  Even though this was an experiment she did with high schoolers I thought the concept was still at a level that my girls could understand.

My little one who is two was not really sure what we were doing and was much more interested in eating the whip cream than seeing how a mountain was made.  By my oldest got it and thought the whole thing was pretty cool.  I am pretty confident that she understands how mountains are made now and in the future we may try and get into some of the other types of plate tectonics when she is curious about something else.

What is happening with this experiment? Plate Tectonics is just a theory at this point but one that many scientist believe to be true.  There are three different types of plate tectonic boundaries divergent, convergent, and transform plate boundaries.  In this experiment we are testing the Convergent Boundaries, where two plates push together and form mountains.   The kids will see that when they push the graham crackers together they push upwards to form a mountain.

Graham Crackers (2 for each child)
Whip Cream
A Plate
Bowl of water

How are Mountains MadeDip each graham cracker in the water (for just a second, you don’t want them too mushy)

How are Mountains MadeLay your graham crackers on the whip cream wet sides facing each other

How are Mountains MadePush your graham crackers together to see how they form a mountain

    What a clever experiment. I am going to share this with my daughter who is a teacher. She is always looking for new ideas.

    Nice idea, wish I’d seen this when I was teaching middle school physics! I just wanted to clarify one thing though. A lot of people think the word ‘theory’ is similar to the word ‘guess’. Scientists use this word very differently, and put a lot of evidential weight behind the word ‘theory’. If it’s only an educated guess, they’ll call it a hypothesis. To be called a theory, an idea will have been tested widely and vigorously by many different scientists in many different ways. The vast majority of scientists who study geology accept that this theory has enough evidence to make it rock-solid (pardon the pun). Yes maybe someday someone will find evidence to the contrary, but at the moment no such evidence exists.
    I just don’t want people to think that we’re teaching fluffy guesses, since in conversation people use the word theory so lightly, so maybe this is just a scientist’s guess! Not so! There’s a huge body of evidence that supports it, so you can be quite confident when you teach this!
    Happy experimenting :)

    Hey!, can i ask, are those photos yours or downloaded some photo banks?
    I am sorry 4 my bad english, neverthless i believe that you’ll you can still understand my question.

    I love this idea! It is such a great representation of how plates move and how mountains are formed, which can be such a difficult concept to grasp.
    The one comment I have is that in this you mention that plate tectonics is “just” a theory that many scientists believe. However, a theory in science is a bit different than the non-scientific use of the word. For example- gravity and the idea that the earth rotates around the sun are also both theories!
    “When used in non-scientific context, the word “theory” implies that something is unproven or speculative. As used in science, however, a theory is an explanation or model based on observation, experimentation, and reasoning, especially one that has been tested and confirmed as a general principle helping to explain and predict natural phenomena.” – Kim Ann Zimmermann,

    Thanks for the awesome idea for a mountain explanation!

    I love your science experiments! I am taking an earth/space science course as part of my masters program and plan on using these in my lessons I am presenting to other teachers. I am sure they will be put to good use in the future with the students as well. :)
