Science Sampler 1

We have had a great seventh week of camp! This week is Science Sampler where we learned about different sciences. 


Playing with oobleck.
Monday was all about messy science. We made oobleck featured in Dr. Seuss's Bartholomew and the Oobleck using cornstarch and water. Oobleck is a "Non-Newtonian" liquid which means it is a runny consistency when you let it move freely through your hands and a solid when you apply pressure to it.










Dry Ice Bubbles
Another interesting experiment we did was dry ice bubbles. We were able to hold a solid bubble filled with fog in our hands! We also used various materials to create our own bubble wands and make gigantic bubbles.

Look at that giant bubble!



Goggles demonstrating insect eyes



Tuesday we learned about incredible insects. Using special insect goggles and other various materials we were able to compare the anatomy of an insect to ourselves. We discussed important adaptations that some insects have such as camouflage and colored our own butterflies to hide around the museum, and then we created an insect of our very own.








We also played a game called "The Waggle Dance" in which some of us were forager bees gathering nectar (scented paper flowers with sugar attached) and the rest of us were worker bees taking care of the hive then matching the scent of the flowers that the forager bees brought back. This demonstrated the real roles of bees in the hive.



Smelling the flowers for its scent.






He found the flower with sugar!



Making your own insect.
Look at that insect!

Looking at the parts of a cell.

On Wednesday, we talked about how our bodies work starting with cells! We created a cell and learned how all of the different smaller parts of the cell work in living things.









Making the lungs

In order to demonstrate how our lungs work, we created a model lung in which the straw represented our wind pipe taking in air, the larger balloon at the bottom demonstrated our diaphragm contracting, and the smaller balloon inside the cup represented our lungs filling with air when these parts of the body work together. We also checked our vitals such as our heartbeat and blood pressure and discussed ways in which we can be healthy in our group!

Checking our vitals



A Cloud in a Bottle
 Thursday was about weather. We created our own miniature water cycle experiment using a bowl of water, some clear plastic wrap, and a coffee mug to demonstrate all of the steps. We also made a cloud using a plastic bottle with a small amount of rubbing alcohol. We pumped air into the bottle using a tire pump, and when we removed the pin, the air pressure dropped, and the water molecules clung together creating a cloud. To continue the discussion of clouds, we also observed some outside and journaled about the types and shapes of the clouds that we saw.






Friday was all about Bats Around the World. Michelle from the Organization for Bat Conservation's Bat Zone brought some live bats to show us.  She talked about the importance of bats and even helped us to debunk some bat myths.  We talked about how some bats use echolocation to find their food.  She had a special machine where we could hear the bat's echolocation.



Listening to the echolocation of the big brown bat.







Then we played an echolocation game where we simulated the sonar method of echolocation that a bat  uses by playing a game where we used sounds to locate our "food".  The bat sent out a sound signal to find the other players (the insects or food).  We also made our own origami bats.
