On the fifth day of Christmas Science, my mommy made with me…Santa going down the chimney! There’s something magical about this time of year, with the lights, cocoa, songs, and holiday cheer. But one of the most persistent questions has always been… how does Santa fit down the chimney? We decided to explore this question for the holidays. However, instead of using the familiar holiday mascot, we’re using hard boiled eggs! In today’s science experiment, we tested the effects of heat and ice on air pressure within a bottle! Our idea was that we could get the eggs into both bottles, simply by changing theRead More →

On the 2nd Day of Christmas Science, my mommy made with me…Frosty The Snow-Can! For our second day of science, I wanted to explore something that we desert dwellers don’t get to see very often… frost! I learned that we could explore making frost right in our kitchen, with just some water, salt, and a can! Of course, we also needed to learn a little bit about salt and how it interacts with liquid water, ice, and the freezing points of these materials! But first, let’s the activity!Read More →

What can you do with a cardboard box, wooden skewers, marbles, and hot glue? You can make a pinball machine! Over the summer, our family took a trip to Las Vegas. While we were there, Kat and I went to check out the Pinball Hall of Fame! We had $18 in quarters and a lot of arcade ambition, we were ready to go play some pinball! While we were listening to all of the bells and whistles and watching the cool mechanics of the games, Kat and I thought about how great it would be if we had our very own pinball machine at home. WeRead More →

Let’s get this ball rolling! I am fascinated with Rube Goldberg Machines. I remember when Pee Wee’s Big Adventure came out, one of my very favorite scenes was when he woke up, and this elaborate machine made his breakfast. I thought, how cool it would be to wake up to a pancake breakfast every morning, without having to do anything!Read More →

Have you ever rubbed a balloon on your head and watched the hair stand up? Have you ever tried to bend water? Did you know that you can turn on a light without flipping the switch? The secret is in the static. Static Electricity! Electricity is all around us. We can see it as lightning in the sky, and we can use it as we power the many electrical devices in our homes. It is even present in our own bodies as the neurons in our brains fire off electrical impulses, resulting in the messages that cause our muscles to move. Electricity is the physicalRead More →

“We embarked on our journey to the stars with a question first framed in the childhood of our species and in each generation asked anew with undiminished wonder: What are the stars?”  ~Carl Sagan I love to learn about space and space exploration. When I was a little girl, I would wake up early before school to watch the space shuttle launch, and dream about one day going to Space Camp. I loved going to the planetarium, and I would collect star books and try to find the constellations in the night sky. As my own daughter has grown up, we have begun to shareRead More →

Sometimes even birthday presents can lead to homeschool adventures… For my birthday this year, my husband bought me an acoustic guitar. I do not yet know how to play the guitar, but I find learning it to be a very fun and rewarding experience. Part of this fun stems from the beautiful sounds that emanate from the strings. Kat and I took turns tightening and loosening the strings as we tuned the guitar, listening to the differences in sound it created. We strummed softly, and pulled hard at the strings, listening to the new sounds we could make. It didn’t take long for these play timesRead More →

We’re going to find the best bubble recipes, and a really easy way to explain surface tension! What better way is there to learn about surface tension and water molecules than by playing with bubbles? Kat and I have been having a lot of fun exploring the different ways that liquids interact with each other, and the reactions that can take place. This time, we decided to explore surface tension by learning about how bubbles work! Even better, we’ve taken our lesson to the park and have invited the other kids to come along and learn with us!Read More →

This week, Kat and I have been studying the various stages of matter! Today, we focused primarily on properties of matter, and ways that you can distinguish between them. We began by asking the question, what is density? Density is a measurement of mass, or the relative heaviness of an object with a constant volume. Simply put, density is a measure of how much “stuff” is in something. That “stuff” pertains to atoms and molecules, which make up the mass of an object. For example, in a liquid, the molecules are loosely “hanging out”. Kat and I demonstrate this by clasping our hands closely together,Read More →
