Act II: The Shrinking Egg!

We continue to amaze ourselves as young magicians, but we did it again! We mastered yet another egg magic act! This one is called the "Shrinking Egg," and the name will not leave you disappointed. My students took turns pouring Karo Syrup (corn syrup) on top of our shell-less egg. Over night, our once opaque egg turned into a shriveled up mess! It was pretty cool to see this huge change, and my students LOVED feeling the egg.

My Peeps Are...Dissolving?!

Welcome back to our continuation of the Dissolving Peeps Experiment! My students made their Day 3  peep observations. Compare these photos to those of my previous post. :) 

Day 4:

Still bright pink, but starting to get smaller in size.

WHOA! Our poor little peep only has half of his body left!

This looks totally and completely disgusting, but of course, I still had PLENTY of students who offered to eat this peep right up (don't worry: I did NOT allow that to happen!) GROSS!

So fresh and so clean! This little peep has been stripped of its pink-ness but smells great!

My students completed their observations and noted that the vinegar had the biggest chemical reaction to the peep. We were surprised because many of us (myself included!) thought that the Pepsi Max would cause the peep to dissolve the fasted. I loved this experiment because my students looked forward to completing their observations each day and were telling their parents all about it!

Check Out My Peeps!

 I told my class that "I brought my peeps with me to school today," although that one went over their heads:) Their interest was peeked when I pulled them out of the package and discussed our new science experiment that will take place for the rest of the week. My students were given a spreadsheet with Day 1- Day 5 across the top and a box for each ingredient going down the left-hand side. Their job was to observe any changes that occurred within our peeps. Each day, students are to complete their observations. We then discuss our findings with the rest of the class.

Day 1: We set a peep in the following liquids: water, apple juice, vinegar, soda (we did Pepsi Max), and laundry detergent.

Day 2: Here are some pictures from what we've discovered so far:
Almost no change with the water, except giving the water a little pink tint.

The eyes are starting to"melt" or slide down the peep's face.

Lots of changes! Our peep has actually lost part of his body in the vinegar-yikes!

Very stained and pretty spongy.

We have all been surprised with the detergent so far. The pink has been magically wiped away, and it is is really soft to the touch.

Keep an eye out for Days 3-5 to come soon!

We're Magicians: First You See an Eggshell...Now You Don't!

You heard right! My class can now successfully complete (drum roll please)....THE DISAPPEARING ACT! (With an egg that is!) We are trying out some new science experiments, and this one is proving to be a hit! We put a raw egg in a glass bowl and poured vinegar over the top. I placed this under my data projector while we were working on an activity so my students could look up and observe what was happening every once in a while. They were excited with all of the bubbles that were forming around the egg, but they were in for a huge surprise (and so was I, this being my first time doing this and all!).

After sitting for the rest of the day and all night, my students were anxious to see what changes had taken place. They put their Scientist's Goggles on (so to speak) and observed the egg. We noticed that there was a lot of things floating towards the top of the bowl of vinegar. We decided to explore further and touch it. When I rubbed it with my thumb, the shell (or what used to be the shell) came right off! The kids oohhhed and awwweed; they were pretty impressed. After the entire white shell was off, we were left with an egg whose yolk you could actually see. I had my students come up and hold it in their hands to feel our egg's newfound texture: we decided the best way to describe it was "water balloon." 

We are now exploring another experiment with this egg. We poured Karo Syrup over the top of the egg and are interested to see what results we get with this one! Stay tuned!
