Science Fun

This year, our science focus was on Biology.  We used Christian Kids Explore Biology as our book.  It had a lot of hands on things we were able to do,  but some days the kiddos just wanted to break out of the book and do something different.  Just one more reason I love homeschooling!  So,  I checked the internet and found this site that has so many science experiments using ordinary things around the house.   

Here are just a few of the things they did:

For the first one, they started with a tray of milk, added 6-8 drops food coloring in separate areas on the tray, then they placed about 5 drops of liquid dishwashing detergent to the middle of the color areas.  The result was a wonderful tie-dye of colors in the tray.  I think this one was their favorite. (I evidently added these pictures in the wrong order,  just scroll up ;-) ) 

Blobs in a bottle - Take a 1 liter soda bottle rinsed out and add 3/4 cup of water.  Then,  pour in vegetable oil until the bottle is almost full, wait a few minutes for the water and oil to completely separate.  Add 10 drops of food coloring to the bottle (obviously we used red, but you could use any color).  The drops pass through the oil into the water below.  Break a seltzer tablet in half and drop the half tablet into the bottle. The tablet will sink to the bottom and the blobby fun begins.  When the blobs slow down, just add the other half a seltzer tablet and the fun continues.  



  This one was interesting as well.  In a small, plastic soda bottle, we put 1 inch of warm water and added a packet of yeast.  Then, added 1 tsp of sugar and swirled it around.  Then, we placed the balloon on top of the bottle (we blew the balloon up a few times so it was stretchy - is that even a word), and waited!!   The second picture is after about 15 minutes, the last picture was after 1 hour.  Pretty cool, right??

 

We also made lava in a cup,  but my pics did not turn out very good on this one.  All I have is this semi-decent video that will not even play right on here.  However,  using a clear drinking glass fill the glass about 3/4 with water.  Add about 5 drops of food coloring (again I used red since it is suppose to look like lava), slowly pour 1/4 cup vegetable oil into the glass - note again the oil floats on top of the water.  Now,  sprinkle 1 teaspoon of salt on top of the oil.  Now,  stand back and watch the blobs of lava move up and down in the cup.  It was way more enjoyable than this terrible video, I promise. 

 

 

Another fun school day in the books.  While this homeschooling thing is NOT easy, some days it sure is FUN!!!  As we wrap up this year,  I will see what other fun things we did that I missed blogging on.  Things just get so busy in this house/school house!!  I have enjoyed this year, and hope the students have as well.
