74% of middle school girls express an interest in engineering, science, and math, but only 0.3% choose computer science as a major when they get to college. (girlswhocode.com)

According to the University of Florida, students who engage in music education often perform better on math tasks. (eschoolnews.com)

People in STEM careers see statistically higher wages than those who are not. They are prepared for the future and ready to manage new technology.


Why I Created STEAM Ahead STEAM Education. We hear all about it lately, on the news, in books, and a plethora of other sources. But what makes STEAM education so important? It prepares our youth for the future, and creates intelligent minds that have the potential to do anything. Often times, kids lose interest in STEAM over time, especially girls with regards to STEM education. It is our duty to inspire and promote today’s young minds to be the best that they can be. So STEAM Ahead was born as a result. Holding classes at the local library every Saturday, I was able to spark an interest in the children of my community. Some even showed up to the program wearing lab coats to express their enthusiasm. In all, this was an extremely rewarding experience that should absolutely be continued by the next generation of STEAMers!


Be the change you wish to see in the world. Inspire others to participate in STEAM education. Become an educator yourself.

Name: _________________

The Science of What Happened 1. Can you make a liquid float? a. The water, oil, and corn syrup all have different densities. Objects that are more dense will SINK, and objects that are less dense will FLOAT. When you added the corn syrup, it did not mix with the other liquids, but SUNK to the bottom. This means that the corn syrup is MORE DENSE than the other liquids. The oil stayed on top, so we can conclude that it is LESS DENSE than the other liquids.

2. Lava Lamps a. To figure out what something’s density is, you can compare it to other things. In this case, we compared the densities of the oil and water. We know that oil is LESS DENSE than water. Therefore, the oil floats ON TOP of the water.

Experiment Set 3: Ooblek/Fluffy Slime  Non-Newtonian Fluids  Elasticity  Polymers Get messy with these fun experiments, and learn the science behind slime!


Name: ______________________

OOBLEK You’ve all heard of solids, and you’ve all heard of liquids. But what happens when something is both a solid and a liquid? Materials:  1 part water  1.5-2 parts cornstarch  Food coloring (optional)  Bowl  Spoon Procedure: 1. Add the water to a bowl or plastic container. 2. VERY SLOWLY, and using the spoon, mix in the cornstarch a little bit at a time. 3. Slowly add food coloring to the mixture, if desired. 4. Pick up the ooblek. What happens when you let it fall through your fingers? 5. Next, try punching it. Is it hard or soft? 6. When you are finished, put the ooblek in a plastic container and fasten the lid tightly. The Science Behind It Ooblek is called a NON-NEWTONIAN FLUID. That means it’s both a solid and a liquid. Non-Newtonian fluids are named that way because they don’t

behave like normal solids or liquids. When you hold it in your hand, it falls through your fingers. However, if you try to smash it or punch it, it will act like a solid and even crack. The ooblek is also an example of a polymer, which just means that it is made up of large chains of molecules called monomers. You can try playing with it as much as you want to see how these properties function!

Fluffy Slime Slime. It’s the latest obsession. It’s every child’s dream, and every parent’s nightmare. But what makes fluffy slime so much fun? And how does it all work? Let’s find out! Materials:  1 part Elmer’s Washable Glue (PVC Glue)  1-1.5 parts foaming shaving cream  Baking soda (optional)  Food coloring (optional)  Saline solution (contact lens solution works fine)  Bowl/plastic container  Spoon  Rubber gloves (optional) Procedure: 1. Add 1 part of Elmer’s Washable Glue to a plastic container or bowl.


Name: ______________________

2. Add a few drops of food coloring, if desired. 3. Add 1-1.5 parts of foaming shaving cream to the container/bowl. 4. Mix thoroughly using a spoon. 5. Add the contact solution about one tablespoon at a time. 6. Continue adding the contact solution until the slime starts holding together and becoming less sticky. 7. Using your hands (with gloves on ), knead the slime until it arrives at the right consistency. 8. If the slime is still sticky, add more contact solution, and a pinch or two of baking soda. 9. If the slime is too watery, add more shaving cream. 10. When you are finished, put the slime in a plastic container and fasten the lid on tightly. The Science Behind It When you mix the glue and shaving cream, nothing happens. That’s because there’s nothing in either of these that bind to each other. The glue is made up of chains called polymers. The contact lens solution contains a chemical called boric acid. This substance, when mixed with water, helps to connect those chains, and give the slime the consistency you all love to play with. In short, slime is super fun, but when you learn exactly why it is the way it is, you learn something as well!

Questions to think about: 1. What happened when you held your paper up to the heat source? _____________________________________________________ ___________________________________________________ 2. Did you expect to see something different than what was predicted? _____________________________________________________ _____________________________________________________

The Science of What Happened Invisible Ink – Lemon Version  When you held your paper up to the heat source, you probably noticed that your secret message was revealed. o Everything is made up of carbon. Specifically in lemon juice and other fruit juices, there are carbon compounds. o These carbon compounds typically have no color when they are not heated, and in their natural state. o When you added heat, these carbon compounds broke apart, resulting in carbon being released. o The air contains oxygen. So, when the carbon was released, it reacted with the oxygen in the air, causing a process called oxidation. The lemon juice then turned a brown color.


Name: _________________ Invisible Ink – Baking Soda Version  When you painted over the mixture with grape juice, you probably noticed that your secret message was revealed. o Baking soda is a basic substance. Basic substances (bases) are bitter, are poor conductors of electricity, and can feel slippery. o The grape juice is an acidic substance. Acids taste sour, are good conductors of electricity, and are typically liquids. o When you combine the grape juice and baking soda, the grape juice is an indicator. This means that it can tell whether a substance is an acid or base. So, because the baking soda is a base, the grape juice changes color to show that. o And as a result, you’re able to see your secret message!
