Top Ten Household Items #10

#10 on the Top Ten List of Household Items to Use in Your Science Classroom is:

Aluminum Foil

Here are a few ways to use aluminum foil in your classroom:

Clean Your Silver
Penny Boats
Sugar Cube Rock Cycle

I really thought I'd find more uses for it included in the Science Matters archives, as it seems like I use it more often just a few times per year.  Regardless, I think it still makes the Top Ten.  In addition, to the activities included, it's great to have on hand when you're talking about the elements on the periodic table and it's fun to throw a ball of it in with items to test with a magnet.

Comment on this post to be entered to win a prize box containing most of the Top Ten Items.  And remember, if your comment contains an additional use (not mentioned above) for aluminum foil in the science classroom, you'll receive a bonus entry!  I can't wait to hear your ideas!

  2. Foil makes great parabolic or pizza box cookers for s'mores, hot dogs, cheese sandwiches, etc. Excellent directions on Pinterest. Thanks for the reminder about the rock cycle - my next unit!

  3. Clean pennies
    There are many ways to make pennies sparkling clean. One option is to first lay out a piece of aluminum foil in a tray. Next fill up the tray with some warm water and mix it with salt. Last place the pennies on top of the foil, wait for a couple of minutes, and you'll have sparkling clean pennies.

  4. SOLAR COOKER
    First, you would need a darkened or blackened pot with a lid. This can be a pot such as a cast iron Dutch oven, a black enameled roasting pan such as a chicken or turkey roaster or any pot that you might blacken on the outside with a non-toxic, weatherproof paint.Dark surfaces become very hot; they heat up more quickly than shiny surfaces.

    Then you will need to obtain a clear transparent covering such as a large glass bowl or a durable plastic oven cooking bag.This will be used for retention of heat and will also allow the rays of the sun to be able to penetrate to the darkened cooking pot and food,thus raising the cooking temperatures and preventing the heat from escaping.

    Next you will need a material that will reflect extra sunlight towards the cooking apparatus so as to concentrate the suns rays. This is usually accomplished in the form of some type of reflecting surface such as mirrors, aluminum foil and buffed tin or sheet metal. With the help of a reflecting surface you will be able to increase the temperatures and to cook the food more rapidly.
