Atoms, Sir Rutherford, Table of Elements & Printables

Today we were lucky enough to attend a Science Workshop all about Atoms & Molecules and the Periodic Table of Elements.....aahhhhh yes that scary thing, well at least it has always been scary to me, but thanks to this workshop it is no longer so!

One of the true blessings of home schooling, learning all over again right alongside your kids.

After a discussion about atoms, protrons, neutrons, electrons and the nucleus we learned that Democritius, a Greek philosopher who lived around 400 BC came up with the idea of cutting gold in half until he couldn’t cut it any further, he called that smallest particle the atom.

Sir Rutherford found out (around 1910) what the inside of the atom looks like and his experiment was done with gold foil.

Each child was given a sheet of paper to replicate the gold foil experiment. The paper needed to be cut in half, then in half again and in half again and in half again and so on and so on you continue cutting the piece in half (discarding the other halves) until you can no longer cut any further.

The highest number of cuts our group produced was 14. A discussion ensued as to the number of times we would need to cut our paper in half to get it down to a single atom. We had numbers from 1000 up to some ridiculous amounts that I can't even type out lol!!

In reality we would need to cut our paper in half 31 times to get it down to a single atom.

From there we went on to explore the Periodic Table of Elements. This one little chart often invokes fear in many, but when someone has the ability to explain the chart in an easily understood way all of that fear is released.

The children were all given their own copy of the chart which they would use later when building molecular structures.

After getting home from the workshop I went looking for other charts and found these very cool, full colour, FREE Printable charts. One with images and one without. Download them over here.

The same site also has this set of FREE printable Elements Cards. There are other goodies over there too and you can even order full size posters of the Elements Charts. Make sure you go and have a look.

In pairs the group did some more exploring of the elements. They were given a set of cards they needed to sort and match up. The cards included images, the element symbol and the element names. Some of these were quite tricky but certainly a good way to get loads of practice with them.

I've put together a set for my kids to use here at home so they can continue to learn the various elements. It is only a start and at some point I will add to this set but you can download a copy for your own use here.

Now that everyone had a pretty good grasp on the concept of atoms and their components and the Table of Elements we moved on to building molecular structures.

Starting off with pretty simple structures such as Water and moving along into more complex structures like Ethanol. These kits were certainly a good visual aid for seeing and understanding the structures. I've already begun looking at a kit for home use. For Australian's this is one I am currently looking at which is very reasonably priced.

This brought us to the end of the session. Here each table of children were asked to choose an element. They were given various cards with snippets of information about that element. Together in their small group (after a brief time for brainstorming and preparation) they had to present their chosen element to the larger group. A great way to round out the end of a fabulous workshop.

Some of the resources that were used during the course of the day and recommended as good to have on hand for home use.

I wanted the kids to 'wrap this up' in some way with a brief culminating activity, so I had each of them work on a notebook page for their science notebooks.

We also spent a few minutes learning a little more about Sir Rutherford and completed a "Famous Person page" about him.

Download a blank copy of this here.

Overall this was great introduction to the Periodic Table of Elements, Atoms & Molecules.

Be sure to have a look at Science For Home Educators they offer workshops in Australia and New Zealand and a Science at Home Awards Program available no matter where you live.

Looks like a fun day! We're about to start the periodic table study this term so this has been very timely for us ;)

Thank you for the printable cards! I am pinning this post!

Wow! Thank you so much for sharing your ideas. The topics you have covered in this post, are the ones I'm most intimidated by when it comes to teaching my kiddos. Thank you so much for sharing so many great resources and ideas to make it simple, fun, and easy to learn! I hope you don't mind that I pinned a picture in your post, so that I'm able to remember where I found the info, when it comes time to teach my kiddos.

Ooohhhh, that was a great session, and I love the printables you found. I'm not quite sure when we'll cover chemistry with the kids, for now I've got a combined chemistry/physics board, which more or less works.

Thanks for linking up to Science Sunday!

These are great! Have you looked into the Periodic Table Coloring book by Teresa Bondera? It's also fabulous, not free, but well worth the money spent. Check She does have free stuff as well! Thanks! I enjoyed your post!

Awesome! Thanks for sharing! Very interesting!

THank you for the fun ideas! This is an area that I haven't covered very well with my kids and we are hoping to correct that this year. We also hope to use it in our homeschool co-op.
