Spring Break Camp in Killeen, Texas: Camp Hermione!!!

Killeen group!

Over Spring Break, the ladies of the Clements Boys and Girls Club in Killeen enjoyed exploring the magical world of Hogwarts with the help of Hermione Granger.  From dissecting owl pellets and learning about chromatography to diet coke explosions and more, these ladies discovered the magic of science.

Dissecting owl pellets was a huge hit with the girls.  They were each able to learn how owl pellets are formed and determined their contents with tweezers and a magnify glass.  Many of them found various bones of small rodents and were able to reconstruct the rat skeletons. Then the girls expanded their knowledge of nocturnal creatures with a lesson on bats and echolocation.

Later in the week the girls became forensic scientists and solved a mystery using chromatography.  A mysterious note at Hogwarts was found, so the girls tested the reaction of different inks with alcohol, a solvent, to determine which pen was used to write the note.

Throughout the week, these ladies also participated in discussions about the importance of attending college and the various types of STEM careers they can pursue.  To highlight these discussions the girls made achievement bead bracelets – each bead color representing goals for their future including graduating high school, attending college and graduate school, and pursuing a STEM career.

For a finale the girls learned about the process of nucleation with the legendary mixture of  Diet Coke and Mentos! First the girls experimented with one Mentos, dropping it into a small bottle of Diet Coke.  While that reaction was fun to watch, the girls were most impressed when we dropped a whole roll of Mentos in a 2 liter bottle of Diet Coke. This was well worth the mess.

Exploring the Effects of Oil Spills

The environmental scientists of Trinity!

This week the Trinity Girlstart Club learned about many of the devastating effects that can be caused by an oil spill! We took a look at what it is like to be an environmental scientist by exploring several methods of cleaning up oil slicks in the ocean.  We also investigated a few of the negative effects that an oil spill can have on wildlife.

Bird feathers are soft and light weight. They keep birds warm and allow them to fly.

If a bird’s feathers are covered in oil, it would be really difficult to fly!

Environmental scientists remove the oil from a bird’s feathers with dish soap. “I learned that it can take hours to clean an animal covered in oil!”

One way to remove an oil slick is through absorption. It takes a long time!

Zavala Explorers

This week the ladies of Zavala Elementary explored soil and its characteristics. 5 different types of soil were closely examined by observing and recording its texture, color, and shape. I asked each girl to share something unique they discovered throughout the experiment and collectively we created a result chart. The chart illustrated the differences found among the common sediment or as one girl interpreted, “it’s all soil from the earth but comes in different colors, like people”.

Funnel Filters

Future scientists from McBee Elementary School!

This week the ladies of McBee Elementary learned about water pollution and ways to reverse its effects. We learned about different water pollutants in small groups, and then demonstrated some of these effects on glasses of water. Since each group was now stuck with a soiled glass of water containing dirt, soap and trash, we put our thinking skills to the test and created filter systems. What great engineers!

One of the many filters!

Working hard and having fun.

Putting their filters to the test.

Want to be a Soil Scientist?

Wooten After School Club

This week the girls of Wooten Elementary explored soil and its properties. First the girls made observations as they placed clumps of soil into a cup of water to learn about soil composition. Then in small groups they explored the texture, color, and sediment structure of five different types of soil: silt, clay, natural dirt, sand, and garden soil. Next the girls used their observations to discuss different scientists that study soil for their work and research. Check out those soil scientists!

Yay Dirt!

This one looks like hot chocolate mix, but it feels gritty.

Sand Dunes!

After School Club at Cook Elementary

This week, girls from Cook Elementary sifted through sand as they explored sand dunes! The ladies experimented with wind patterns to create a few different types of sand dunes, and even got to create their own masterpieces by blowing pictures into the sand! Once they had a firm grasp on how sand dunes are formed, they discussed the significance of sand dunes around cities, and brainstormed the pros and cons of trying to build structures to stop a sand dune from damaging a city. Check out the awesome pictures from this week’s lesson!

Look, no hands!

Girls created different types of sand dunes by experimenting with wind direction and strength.
