After School Spring 2018: Week 5

During Week 5 of Girlstart’s After School Program, our young environmental engineers used their problem-solving and critical thinking skills to create water filters! First, they created polluted water to show how human activity can negatively impact the environment. Then, they created, tested, and revised their water filter designs to improve the filter’s effectiveness.

Hands-On Wednesday: Lava Cup

Do you know what happens when you mix oil and water? The oil floats on top of the water because it is less dense. Now add some salt and VOILA! You get your very own lava cup! Because salt is heavier than oil, it sinks into the water pulling the oil with it, and when it dissolve…up goes the oil. This gives a real cool effect. Check it out!
