Build Your Own Atom Model: Fun & Easy Science for Kids


The thought that the world is constructed with tiny little constructing blocks that we cannot see is one thing that fascinates youngsters. It is without doubt one of the causes I actually like this straightforward atom mannequin venture for teenagers to point out them visually what can’t be seen.

Let’s make an atom mannequin!

Exploring Atomic Construction with Youngsters

Possible after introducing the idea of atoms at dwelling or in science class along with your child is a good way to begin conversations and answering questions like:

  • Do atoms make up this desk?
  • My arm?
  • Even the fridge?

Sure, sure, and even the fridge. Youngsters love considering BIG and considering this SMALL is basically, actually BIG. Making an atomic mannequin collectively may help them translate this concept into one thing a bit extra concrete.

What’s an atom?

The whole lot is fabricated from atoms. They’re the tiniest piece of an aspect that also has all of the properties of that aspect. So, if somebody handed you an atom of Helium and you would see all the way down to the molecular degree, you’d have the ability to inform it was Helium simply by seeing what the atom seemed like.

If somebody broke off a small piece {large enough to style} of chocolate chip cookie and also you couldn’t see the chocolate chips or that it was spherical like a cookie, you in all probability may determine it as a chocolate chip cookie from the style.

That’s sort of how this works solely MUCH smaller.

Construction of an Atom:

Protons, Neutrons & Electrons…OH MY!

Atoms are a mixture of protons, neutrons and electrons. The nucleus of an atom seems just like the protons and neutrons are all smashed collectively which creates a spherical heart. The electrons orbit across the nucleus.

The atomic quantity of an atom is the variety of protons in that atom.   The Periodic Desk of Components organizes all of it. It’s like atom alphabetization!

“The whole weight of an atom is named the atomic weight. It’s roughly equal to the variety of protons and neutrons, with a bit further added by the electrons.”

Bohr Mannequin

“In atomic physics, the Bohr mannequin or Rutherford–Bohr mannequin, offered by Niels Bohr and Ernest Rutherford in 1913, is a system consisting of a small, dense nucleus surrounded by orbiting electrons—much like the construction of the Photo voltaic System, however with attraction offered by electrostatic forces rather than gravity.”

Wikipedia <–don’t often use it as a essential supply, however it had the clearest clarification of Bohr mannequin

Let’s construct one for enjoyable!

Atom Mannequin for Youngsters

Atomic Supplies you’ll need:

  • craft pom-poms in three colours in equal quantities
  • craft wire
  • scorching glue gun or common glue and endurance

Find out how to Make an Atom Mannequin:

1.   Every one of many pom-pom colours will signify a distinct a part of the atom:   proton, neutron and electron.

2.   To be quite simple in the present day, we’re making a neutrally charged atom, so we can be utilizing equal quantities of protons, neutrons and electrons.   Earlier artwork initiatives have depleted our pom-pom provide, so the 2 examples we present can have very small atomic numbers.

3.   The wire represents the electron path.   First, style electron paths for every of your electrons.   These are orbits across the nucleus, so make them a bit wider within the center and slender on the ends.

4.   Sizzling glue the electron pom-pom onto the wire {we lined the tip joint}.

5.   Create a nucleus by gluing the proton and neutron pom-poms collectively in a ball.

On this instance:   blue=protons, yellow=neutrons and orange=electrons – this atom mannequin has two protons, two neutrons and two electrons which makes it Helium

6.   Make brief stability rods out of the wire to connect the electron paths to the nucleus.   To be fancy and reduce the visibility of those connector items, I glued the soundness “rod” piece into the nucleus after which hooked up it on the electron path below the electron pom-pom on the authentic joint.

On this instance:   inexperienced=protons, orange=neutrons and yellow=electrons – this atom mannequin has three protons, three neutrons and three electrons which makes it Lithium

7.   As soon as the electron/electron paths are hooked up to the nucleus, you’ll need to do some atomic orbit arranging to your mannequin of the atom. The bigger the atomic quantity, the extra arranging!

Atom Actions

  • To start with, my youngsters LOVED making this mannequin of an atom.   We ended up making a LOT of atoms.   Whereas we made each, we mentioned the atom anatomy and which elements belong the place.
  • Every of the atoms we construct we’d lookup its atomic quantity on the Periodic Desk to see the identify of what we had made.   I beloved how straightforward that is to do for teenagers and on a number of events, I used to be Googling aspect abbreviations and pronunciations.
  • Atom drawing:   After this lesson, I observed that the doodles and drawings of the boys began having objects in orbit.   To have this 3-D idea interpreted by them in 2-D is fairly cool.
