Cookie Moon Phases


I've seen these cookie moon phases before (click here for a description of the activity on Science Bob's Blog) and wanted to share my "Moon Phase" cookie story.


After seeing these online I thought it would be fun to do it in class as part of our Astronomy unit. I decided to make these at home. They turned out adorable. Then I decided to eat them (justifying that I would let my kids eat them in class :) It quickly became apparent that 8 Oreo cookies was way too many to eat (I definitely felt queasy). I went back to the online directions and found out that I was suppose to use "mini Oreo cookies" (which made much more sense).



A note of caution, the mini Oreo cookies may not be as cost effective with large groups of children (when I taught middle school I had 80+ children). It is definitely cheaper to buy the generic chocolate sandwich cookies. I would just provide a snack or sandwich baggie so the kids could take the leftovers home.

What a fun and yummy idea!!!

I have done this activity for many years with second grade. It is one of my favorite ways to reinforce moon phases after teaching it. I too felt that the mini Oreos were the way to go. Always had enoughbleft overs for an aftervschool snack.

This is a great idea, however the first and third quarter moons are mislabeled. The waxing "half" moon is the first quarter moon. The waning "half" moon is the third or last quarter moon.

ha! I guess I've never read the directions, either (just loved the pictures), because I never noticed you're supposed to use the mini cookies. Glad you said something about it here. I'll teach 500 students (the entire school) in my K-4 science position next year. I wanted to do this activity with at least a couple of grades, but that could mean way more money from my pocket than I'm willing to spend. Hmm.... Thanks for the food for thought (pun intended). :)

Eight Oreo cookies is too many? I eat them by the sleeve! Ha ha.
Wouldn't the smaller ones be harder to do, though? Maybe we will try partners.

Weathering, Erosion, and Deposition Activity

I saw this activity at a science conference years ago and haven't had a chance to use it in a classroom until this week (mainly because I didn't teach weathering, erosion, and deposition). It is a great way to reinforce the definition of the weathering, erosion, and deposition in a highly kinesthetic manner. Basically you break the students up into groups of three. One group is "Weathering" another group is "Erosion" and the third group is "Deposition". Add tape to the back because you are going to stick them to the forehead of the children in each group. The "weathering" students get a sheet of paper that is their "rock" they will be breaking down. At the start of the activity the "weathering" students will start ripping tiny pieces of their "rock" and handing it to the "erosion" students. The "erosion" students will be running their tiny piece of "rock&

Picture of the Day - Activity

I attended a training class and a science coach shared an activity that he does with his students to help them differentiate between observations, inferences, and predictions. He puts a picture on the interactive white board as a warm up (he gets the pictures from a variety of sources but uses National Geographic's Picture of the Day a lot). The picture above is from the National Geographic site. He has the students make five observations. Then he makes the students make five inferences. Finally he has the students make five predictions. He does this every day and it really drives home the difference between those three key inquiry vocabulary terms. I've done this activity with both my sixth and fourth grade science classes and the students really got into it and became proficient at telling me the difference between those terms.

Rock Cycle Activity

Today I got to spend the day with a 3rd grade science teacher doing a rock cycle activity. She had asked for help a couple of weekends ago to find some engaging rock cycle activities for her students. I quickly did a Pinterest search and came up with a link to a middle school blog where they featured a fun looking rock cycle station activity. That website took me to the originating activity site - Illinois State Museum Geology Online and their Ride the Rock Cycle activity . I read through it and felt it was doable for third graders (although I was a little nervous about the cartooning). I offered my help and we put together the activity. The kids did it WONDERFULLY. It was one of those lesson you wish was observed (but of course never is :) They are on an alternating science schedule so she only had two of the four classes today but it was a good sampling of children. She had one class that had a high portion of struggling learners and the second class had a high
