So I’m going back through photos this summer and I’m once again blown away by the phenomenal experience that our NCS high school science students provided for their elementary friends at ExploreZone 2019! It was an incredible day of science adventure and fun – for all!

NCS elementary students explored an awesome glow wall, shooting flames, liquid sand, virtual reality, Bernoulli’s Principle, gooey worms, exploding art, and many, many other exciting physical science and life science exhibits – and our big kids made it possible. I am forever thankful!!

Click to see hundreds more photos and videos from ExploreZone 2019. Yeah – we took a lot of pictures!

Hope You’re Having a Great Summer!!!

This is soooooo cool! Wow, sounds like a great summer project! (Get it? Sounds? :)) Or maybe a project for my budding physics students? Hope you are having a great summer break!!

Psalm 19: 1 -3, “The heavens declare the glory of God; and the firmament shows His handiwork. Day unto day utters speech, and night unto night reveals knowledge. There is no speech nor language where their voice is not heard.”

Physics 4-17-19 Harmonics & Beats

Posted on by

PHYSICS: So why do instruments that are playing the same note sound so different? Here’s our discussion of harmonics and beats.

Speaking of discussion – what did you think about the Tacoma Narrows Bridge? Any ideas on an explanation? Here’s a link, if you’d like to see it again: Tacoma Narrows Bridge

Physics 4-16-19 Sound Intensity and Resonance

Posted on by

PHYSICS: Great music today! And great discussion of intensity and resonance! Were you okay with the problems?

Couple of items to apply for further contemplation – so how does the whole hearing thing work? I mean, I know the little bones in your ear move, but why? Is resonance involved? Great item for application/discussion!

Physics 4-12-19 Wave Interactions

Posted on by

PHYSICS: Cool thing, standing waves! How’d you like making waves with slinkies? Are you okay with constructive and destructive interference?

Here’s the slinky activity for today. Stretch the slinky a pretty good length between you and your partner, but not enough to overstretch the slinky. Below that, the discussion of wave interactions.

Physics 4-11-19 Waves

Posted on by

PHYSICS: Hey guys! Here’s our discussion on the properties of waves. Remember anything from your earlier 8th grade physical science days? Problems are pretty simple for you, I think. Do you remember the main formula from chemistry? Speed = wavelength x frequency (c = λf).

Easy peasy – and don’t forget the applications!

Physics 3-5-19 Bernoulli

Posted on by

PHYSICS: Were you amazed at the effect of change in surface area on the velocity of water, and especially the pressure of water, flowing through a tube? Thaaaaat explains how a calm ride on a lazy river can turn crazy in just a few seconds!

Today we concentrated on quantitative applications of Bernoulli’s Principle and a few practical applications. Tomorrow we’ll take a look at the problems and a couple more cool ways to apply Bernoulli!!
