Ending with a Bubble?

So the last day of camp was all about bubbles-well not really all about bubbles. First activity dealt with dry ice and exploring how dry ice (which is really carbon dioxide in a frozen state) reacts with water and soap. Campers learned that if you change the temperature of the water you can change the type of bubbles produced!

After the dry ice activity, students learned that you can hold a bubble made with dry ice-but not with your hands! In order to hold a dry ice bubble, you have to use mittens! So on a really hot day our students put on their gloves for the sake of science!

Thanks to all of our parents for sharing their children with us! We had a blast!

MATH is BEAUTIFUL!

MATH IS BEAUTIFUL! Today, high school math teacher Dr. Darwin Mills came and showed the beauty of mathematics. His energy kept us on our toes and his teaching made us all want to guess what math problem he was going to give us next! His unique methods for teaching and his innate ability to capture the attention of the entire group left the campers AND the teachers wishing that Dr. Mills had been their math teacher in school.

Below is an example of one kind of math we learned today called "pretty math":


1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432 (The Doorway)

It may be a hot August day, but we were all wearing our mittens as we investigated Mr. Levering's scientific question: "How do mittens keep us warm?" We worked with temperature probes and the computer program Logger Lite to further explore this question. The campers learned that it's not the mitten that produces heat, but the individual's body heat. This body heat is then trapped inside the mitten and keeps us warm.

After we conducted our scientific experiment with mittens, we transitioned to a job as mathematical problem-solvers "on the farm". Here is a picture of one of our mathematicians using his problem-solving in the cow pasture:

Then we tested our memory with an exciting game led by Virginia Beach's own Dawn Sawyer, a gifted resource teacher, and Susan Hudgins, a math specialist.

OOOOBLECK!!! This word is as messy and exciting as the activity we did today. Corn starch and water are the perfect combination for a gooey, sticky mess that kids love! This activity was led by Ms. Adams, a Senior in Regent University's Interdisciplinary Studies program, and a teacher's assistant in the Chesapeake schools. Below is a video of Ms. Adams and a few of the kids experiencing the excitement of Oobleck:

I scream, you scream, we all scream for ICE CREAM! Our final big activity for the day was making ice cream! The kids loved this tasty treat--not just because it tasted great but because they each got to make their own individual bag of ice cream! Here is a "taste" of the yumminess we prepared:

Here is the recipe for the icecream!

Today was an exciting--practical application--math-filled day that ended in a tasty ice cream treat! For all our campers and teachers, this is Rebekah, signing out.

Whelk!

Whelk! No, this isn't a misspelling of the word "welp"--it's actually the name of a creature we learned about this morning as the Marine Science Museum came to visit the camp--aquarium in tow. Questions abounded as the children learned about the ecosystems of the Chesapeake Bay and got an in depth look at the creatures that inhabit the different areas of freshwater, brackish water and saltwater found in the Bay. Below are pictures of the Whelk and of our future generation of marine biologists!

Geometry came alive for the kids through a program called Geometer Sketchpad, and we studied tessellations with the help of our esteemed guest Dr. Trintor of UVA!

Marshmallows flew as the students tested their ability to launch the marshmallows with precision and accuracy. Our challenge was to create a lever capable of catapulting various-sized marshmallows into a bucket three yards away. Students learned how to vary the fulcrum of the lever to reach the goal. To finish the day, we had a competition to see who could accumulate the most points in a skee ball game, launching the marshmallows into the buckets for multiple points. It was neck and neck, but in the end, three sticky marshmallowed campers took the lead!

Another great day at camp! For all the teachers and campers, this is Rebekah and Brian, signing out!

Flying Hot dogs!

"Flying hot dogs" --were the cries of the children as everyone gathered outside to see the amazing solar bags collect air and then rise as the sun changed the properties of the air inside the bag.

"Scientists from Pioneer Astronautics and Jet Propulsion Laboratory conducted successful tests of its Mars solar balloon inflation system using [Steve Spangler Science's] Solar Bag. This video give you a bird's eye view of what [the] Solar Bag looks like at about 120,000 feet above the Earth" (Steve Spangler, 2011).

Today the children also presented their inventions as engineers of creatures with plane and solid shapes, and at least two moving parts. Here was the winner of the most impressive creature:

After the students debuted as engineers, they tested their lungs with this next air-blowing experiment.

"The long bag quickly inflates because air from the atmosphere is drawn into the bag from the sides along with the stream of air from your lungs. For you science enthusiasts out there - here's the technical explanation... In 1738, Daniel Bernoulli observed that a fast moving stream of air is surrounded by an area of low atmospheric pressure. In fact, the faster the stream of air moves, the more the air pressure drops around the moving air. When you blow into the bag, higher pressure air in the atmosphere forces its way into the area of low pressure created by the stream of air from your lungs. In other words, air in the atmosphere is drawn into the long bag at the same time that you are blowing into the bag (Steve Spangler).

Finally, the students designed different experiments and projects to see how air affects the movement of objects:

We had a wonderful day at the Martinson's Center for Math and Science!

It is Raining Soda!

S.T.E.M (Science, Technology, Engineer, and Mathematics) camp started off with rain-but not real rain-diet cola rain! Students got to observe what happens when you add mentos candy to diet cola and then turned their questions into experiments! Students learned about air pressure and even got to see that they really could sit on a bed of nails!

Tune in tomorrow for more fun!
