Splitting Molecules: Electrolysis

Image
Students are always excited when they get to do something that they perceive as difficult. Splitting a water molecule sounds pretty complicated! In reality this is a pretty simple process. As a teacher who is two years through Open Sci Ed implementation, I am always looking for opportunities for students to do a little more because in some instances the curriculum can get a little discussion and observation heavy. The electrolysis demonstration in 7.1 Lesson 10 was a perfect opportunity for students to complete the set up and observe the process. My challenge was to come up with a simple set up using materials that were easy to obtain and inexpensive. Material Notes (per set up) 8 oz plastic cup - clear works best for easy viewing 2 thumb tacks Styrofoam - I just used some form a package we received Masking tape 9V battery Distilled or deionized water Magnesium sulfate (epsom salt) 2 test tubes (150mm) with stoppers Test tube tongs Matches or lighter Wooden splints The Set-Up Step...

A Look Inside: DNA Extraction

Image
The wonder of DNA - it controls everything your body does and how it looks. You can’t see it without a microscope…or maybe you can!  DNA fills every cell in our body. We can’t even see individual cells without a microscope but this lab allows you to extract DNA from cells, get it to clump together so that you can see it without a microscope.  Of course you will not see the famous double helix structure but students are always amazed with this experience! I have used this format for Open Sci Ed 8.5 Genetics, the Junior Girl Scout Detective badge and the Cadette Special Agent Badge. Material Notes -  Small plastic cup Large plastic cup Coffee filters Large popsicle stick Coffee stirrer or other small straw Salt Soap Water Graduated cylinder (or other measuring instrument) Ziplock bag  Strawberry (I used defrosted strawberries, I have seen kiwi and banana also be successful) 91% isopropyl alcohol - store in the FREEZER and take out right before needed I make trays for s...
