How To - Rain Gauge
































I had made the larger one in the last picture at a science professional development program at Roper Mountain Science Center in Greenville, SC. One of the teachers in the class said that she made them on a smaller scale with empty soda/water bottles so I thought I would give it a shot.
Teacher Tips:
- Have students bring in the bottles. Collect until you have enough. Kids love doing contributing to a project and mine always asked if we had enough yet.
- I took all of the bottles home in a large trash bag and precut all the tops while watching tv (and made the drainage holes). I kept the top and base together by using small cut pieces of packaging tape so that students had a matching top and bottom (they would just take off the tape when we started the project).
- I modeled what I did at home in front of the students in case they wanted to make one on their own at home.
- Make extras of EVERYTHING (bottles and cut pieces of duct tape).
- Pour aquarium gravel into a shoe box and have students use a dixie cup to scoop out (aquarium gravel can usually be found in one of the life science kits).
- I like the red duct tape but at Micheals you can buy all different colors.
- Start the zero point on the ruler just above the gravel. The intent is for students to fill the bottle up with water to the zero line. They would then put it outside and after a rain record how much rain fell (they they would tip over the rain gauge and drain out all the water and then refill water up to the zero line again)
- It helps to have another adult (parent volunteer or adminstrator) help with this project.

Moon Phase Box

I happened to walk into a fourth grade class the other day and they were hard at work making moon phase boxes. They were totally adorable and the kids were completely into it. The teacher very kindly let me take some pictures (thank you Mrs. Parker!) and add to my blog.


Students would need a shoe box and they need to cover the inside and inside lid with black construction paper. Using fishing wire they would hang a ping pong ball in the center of the lid so it is suspended in the center of the box. They then take a flashlight and trace the light end on one of the short ends of the box and then create viewing flaps in the middle of every side (including the one with the light bulb (but that might be slightly off center). It is important that the viewing areas are flaps and not cut directly out (you need to keep the light coming into the box blocked as much as possible).


The teacher used a box cutter to cut the flaps and flashlight hole for the children. I probably would have had studen…

Google Classroom Headers (and Bitmojis)

I recently taught a class on how to use Bitmojis in the classroom to increase student engagement and help with classroom organization and management.

One fun idea was to use them to make custom Google Classroom headers. The idea came from Alice Keeler's blog and she even provided a template for her header.


My computer settings weren't the same as hers so I had to tweak my version.

This got me thinking about how the headers could be changed out frequently, as something new for students to look forward to, when they opened up Google Classroom. In my head I was thinking they could be changed out weekly (38 total headers needed) if time permitted. 



I have several other ideas, templates, and instructions linked in this presentation.



I would love to see other custom Google Classroom Header ideas! Please feel free to post a comment or tag me on Twitter at @techcoachlife.




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.
