Do you love bright and vibrant colored art supplies? Do you ever wonder how these colors are made?  The variety of colors comes from colored molecules that are mixed into the material used to make the product. Some colored molecules are synthetic (or manmade), like the famous Yellow #5 found in food dyes. Others are extracted from natural sources, such as carotenoid (pronounced kuh-RAH-tuh-noid) molecules, which make your carrot look orange, and can be extracted from saffron.  Even… Read more

Engineering Design Process
If you ever rode in a cable car, ski lift, or gondola, you know they make moving over obstacles like lakes, valleys, rivers, or even up steep mountains seem easy. Though it would be pretty difficult to build a full-size cable car in your home, if you have a Mindstorms® kit, you can build a working-model cable car of your own. The engineering challenge is to build a LEGO® cable car that can travel across a string you have suspended somewhere in your house (between two pieces of… Read more

Did you know that the same digital photo you see on a computer monitor may not look as good in print? When it comes to color profiles, there are a lot of options: RGB, CMYK, grayscale and indexed color! How do you choose the right color profile for the job? Read more

Have you ever tried adding green food coloring to your milk? Or blue coloring to the butter you spread on your bread? You may not have tried this, but for years, scientists have studied the effect of color and food appearance on how food tastes. Believe it or not, our eyes are an important part of how we taste and perceive food! In this activity, you will learn about how you can trick your taste buds—with just a little food coloring!

Have you ever wondered what the world would look like without colors? Most of us take them for granted since they are everywhere: blue sky, green grass, the yellow sun, and countless more. Your eyes are actually able to distinguish up to 10 million colors! But where do all the colors come from, and how do our eyes perceive them all? Find out with a little help from some shadows, and create numerous colors by mixing red, green and blue light. Read more

What causes the food coloring to move through the milk? In this week's spotlight: a family science experiment that lets you and your children make a rainbow in keeping with St. Patrick's Day! What happens when you put drops of food coloring in milk? What happens when you add a bit of dishwashing liquid? Put it to the test in this science activity for a fun, colorful look at the role of a surfactant and how it changes the surface tension of a liquid. Family science… Read more

What color is grape soda? If you pour it into a clear glass you can easily see it is purple, but that is usually not its natural color. Manufacturers add red and blue dye to the soda. The dyes mix together and you get purple soda. What if you wanted to un-mix the dyes, could you? Yes! In a chemistry laboratory, using a technique called column chromatography, you could separate the two dyes again. But what about at home, can you use low-tech supplies to do the same thing? In this science project… Read more

Did you ever notice the cool patterns around your footprints when you take a walk in the wet sand at the beach? The pressure of your feet has effects far outside your footprints. Here's a project that uses a simple experimental apparatus to investigate how the volume of wet sand changes under pressure. Read more

Did you know that you can change the genetic code of an organism? This technology is called gene editing or genetic engineering. Using gene editing tools, researchers can delete or modify existing genes in an organism, or even add new ones! With this ability, they can alter the way an organism—such as a bacteria, a plant, or an animal—looks or functions. For example, crops can be modified to become more drought-resistant, or bacteria can be engineered to produce medicine such as… Read more

Why buy it when you can build it? That is the attitude you will need for this project. You have probably seen cell phone holders or stands around the house or in a car. They might seem like a very simple object, but they are a great way to learn about the engineering design process. In this project, you will design and build your own working phone stand. Read more
