Last month our young STEMists tacked chemistry basics, the periodic table, what makes up an atom, and chemical and physical changes. (Note: 360-video @ the end of the post!)
The students started the club session with an interactive presentation highlighting several careers in chemistry. All the careers mentioned have a short career highlight video to provide good visualizes of what the jobs entail, as well as how much additional education is expected. The students also learned the differences between credentials, such as an Associate Degree, a Bachler’s, a Master’s, and having a PhD. We were only able to allow the kids to pick five or six careers during the club, so please sit down and re-explore the interactive presentation with your child at home!

They learned about atoms, which is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud.

The students then began exploring the periodic table and how elements are organized and what different forms the elements exist at room temperature. They further familiarized themselves by playing a couple of games: Element Scrabble, spelling words with the element’s symbols and Periodic Table Battleship, strategically call out the period, the group, and the name of each element to sink their opponent’s ships.

Students applied what they learned from Day 1 about chemical and physical changes to the hands-on chem labs. They learned that chemical changes have certain indicators: change in color, gas produced, temperature change, light produced, precipitate forms, or are irreversible.
The students broke up into groups and did a series of chemical experiments to see first hand what chemical changes look, feel, and smell like.

If slime is still permitted in your household and you’re looking for a Super Fluffy Slime Recipe try this:
- put 3 cups shaving cream in a bowl
- Add in 1/4-1/2 tsp of baking soda and stir
- Mix in 1/2 cup of glue and stir
- Add 1 full tbsp of saline solution and a coating on hands
- Mix until mixture forms a fluffy slimeball
Next month Dr. Brooke Beam, OSU Extension Educator from Highland County will lead us into learning about 360 technology and video and photo production. The students will be exposed to 360 educational VR experiences for an immersive learning adventure. Testing out the new 360 camera, here’s a clip below:
