December was so warm for us this winter that I was sure that we wouldn't get very much snow this year. Well, apparently Old Man Winter changed his mind! In the last three weeks we have had several snow storms. So, I thought that it was about time for me to share about snow! Snow forms by a process of deposition, which means that water vapor in the high in the atmosphere changes directly into … [Read more...]
Freezing Fog {InstaScience}
Freezing fog is a super cool weather phenomena that happens in the cool winter months! We were lucky enough to see some just the other day. Fog occurs when cold air settles in over relatively warm, moist ground. It’s basically a cloud on the ground. Freezing fog is happens when the air becomes saturated with water vapor that is supercooled. Supercooled water is between 32 degrees and 5 … [Read more...]
Scoria {InstaScience}
A few years back, we took a very long road trip out to Arizona to see the Grand Canyon. It was spectacular and I still can't really put into words how amazing it is to see this canyon in person. But a surprising highlight of our trip out there was a last minute addition, Sunset Crater National Monument. We were giddy at the chance to see a cinder cone volcano up close. Not only did we had the … [Read more...]

So like any good homeschoolers, we looked it up and found out that our large grey chunk was actually a piece of basalt! Basalt is an igneous rock that forms when molten rock is extruded out of the ground during a … [Read more...]
Ocean Waves {InstaScience}
There are very few things as peaceful as the sound of the ocean waves as they gently crest onto shore. It is a sound you can count on hearing every time you set foot in the beach. But what causes this to happen? Waves are the result of energy moving through the water. And there are two main causes for the waves we find on the beach. First as the wind moves over the surface of the water it … [Read more...]
Fossils {InstaScience}
We found this fossil of a shell a few years back as we were skipping stones in a local river. Luckily, our daughter turned her stone over and found the impression fossil. Now, the stone is a part of our ever-growing rock collection. Fossils are bits of plants or animals that have been preserved from the past. There are several different kinds of fossils based on how they are formed. The three … [Read more...]
