SLC Young Ambassador Blog: Week 2

22 07 2013

Hello, my name is Alana Zamora from San Marcos, Texas. This year, I was selected as a 2013 Smithsonian Latino Center Young Ambassador; Up to twenty-four graduating high school seniors are selected each year and are given the amazing opportunity to intern in a museum/cultural institution in their local community for four weeks. Currently, I am interning here at the Austin Children’s Museum. I will be posting weekly blog posts to describe my journey here at ACM, as well as, insights into the different summer camps that we offer at the Museum.

This week, I helped lead the ‘Young Scientists’ half day summer camp program for children, ages 4-6. For every half day camp, we have story time, hands-on activities and free play in the Museum. I assisted in leading science and art activities, playing with the children in the Museum and supervising them throughout their time at the camp. At this week’s camp, I had the opportunity to prepare the activities for each day, so I was able to see how much work goes into organizing a camp. Also, I was able to give feedback in ways to improve the activities for next ‘Young Scientists’ camp.

On Monday, July 8th, the theme for the day was measurement. The children learned about time, weight, temperature and length. Some of the activities for that day were, measuring and weighing sand, taking the temperature of warm and cold water, and creating a clock. Another activity that we had the children do was draw a picture of what they think a scientist looks like.

On Tuesday, July 9th, we learned about chemistry, reaction and slime. Camp leaders demonstrated baking soda experiments and helped the children create slime. The slime activity was very messy, but so much fun!Image

     On Wednesday, July 10th, the theme was color and magnification. Some activities that we had were, color mixing with paint, making a solar bead bracelet and Play-dough mixing. One of my favorite activities of the day was creating our own ‘rainbow’ using a flashlight and glass prism.Image

     On Thursday, July 11th, we learned about architecture and electricity. We had the children build houses out of wooden blocks and we had them create their own circuits.

     On Friday, July 12th, we learned about flying. The children learned about bats and made their own ‘bat hats’. They also created their own kite and roto-copter.

     Again, this week was amazing! I enjoy working with the children and watching them learn. Also, my fellow interns and volunteers are truly great individuals! I am amazed with all the learning that takes place during camp and I really do wish that I had the same opportunity at a younger age that all of these children are having now. Learning is fun!

Dancing Raisins!

20 07 2012

Now that it’s summer time, the extreme heat makes everyone want to go swimming! If you have gone swimming with a life vest before you know that life jackets keep you from sinking down into the water, but do you ever wonder how? This simple experiment can help explain.

Here’s what you’ll need:

  • a clear cup or glass
  • some raisins
  • club soda (make sure it isn’t flat!)

Instructions:

  1. First, open the club soda and pour it into the glass
  2. Then drop a few raisins into the cup of soda
  3. Wait about 20-30 seconds to see the raisin’s reaction!

What did you see?

The raisins should have dropped to the bottom at first, started floating to the top, and then fell back down to the bottom again. This should happen continuously for a few minutes! Take a look at how our experiment went:

The reason why the raisins dance in the club soda and then floats to the top is because the bubbles in the soda stick to the rough edges of the raisin making it more buoyant, meaning that it floats easily. The bubbles in the soda are carbon dioxide gas and help bring the raisins to the top, when the bubbles reach the top, they pop and release the carbon dioxide gas into the air. This makes the raisins fall back down again since it is denser than the liquid soda.  The bubbles make the raisins float to the top similar to how a life jacket keeps you above water!

Now that you’ve tried this simple experiment, try putting other small foods into the club soda to see how they react! Although not everything you try will float, it is always good to experiment! You could try peanuts, chocolate chips, apple seeds, or pieces of uncooked pasta to see how long it takes for the bubbles to bring it up to the top and how fast they move up and down in the soda. Let us know what results you got!
