Turn It Off Tuesday

Light switch.

Energy

Did you know that items plugged into an energy source use electricity, even when it is turned off? Today let's turn off and unplug unused appliances and items. Do you have a toaster that is plugged in all day but only use it in the morning? Unplug it! Got a charger plugged in but only use it at night? Unplug it! This will save you some coins while also conserving energy. It’s that easy!

Here are some tips on how to conserve energy during the day or when not at home: 

  • Air-dry dishes rather than using the dishwasher 
  • Wait until the dishwasher or laundry machine is full to begin a new wash 
  • Wash your clothes/dishes before 4 p.m. or after 7 p.m. during non-peak times 
  • Unplug TV’s, entertainment systems, toasters, blenders, coffee makers, etc. when traveling 
  • Turn your thermostat to a lower temperature in the winter and a higher temperature in the summer when you are not home

Solar box oven project

Create a Solar Pizza Oven!

Brought to you by Home Science Tools, here's what you'll need:

  • Cardboard pizza box (Here's an excuse to buy a $5 pizza!)
  • Pencil and ruler
  • Box cutter or scissors
  • Aluminum foil
  • Clear tape
  • Construction paper or newspaper
  • Plastic wrap or large, transparent plastic bag
  • Dish or pie plate
  • Cooking Ingredients, like smores or nachos (Don’t use your oven to prepare raw meat.)
  • Optional: a thermometer that goes up to 250 degrees F.
Using this table, follow along step by step:
Step 1 Use a sharp knife to cut along three sides, leaving about an inch between the sides of the flap and the edges of the lid of a box with a lid.
Step 2 Fold this flap out so that it stands up when the box lid is closed.
Step 3 Cover the inner side of the flap with aluminum foil so that it will reflect rays from the sun. To do this, tightly wrap foil around the flap, then tape it to the back, or outer side of the flap
Step 4 Use clear plastic wrap to create an airtight window for sunlight to enter into the box by opening the box and taping a double layer of plastic wrap over the opening you made.
Step 5 Leave about an inch of plastic overlap around the sides and tape each side down securely, sealing out air.
Step 6 If you use a plastic bag, cut out a square big enough to cover the opening, and tape one layer over the opening.
Step 7  To insulate your oven so it holds in more heat, roll up sheets of newspaper and place them on the bottom of the box, tape them down so that they form a border around the cooking area. Note:  It may be helpful to also tape the rolls closed first. The newspaper rolls should make it so that the lid can still close, but there is a seal inside of the box, so air cannot escape.
Step 8 Take it outside from 11am to 3pm to a sunny spot and adjust the flap until the most sunlight possible is reflecting off the aluminum foil and onto the plastic-covered window. Use a ruler to prop the flap at the right angle. (Optional) You may want to angle the entire box by using a rolled up towel.
Step 9 You can make toast by buttering a slice of bread then letting the sun do the rest. A pie plate would work well so the bottom does not get dirty. Note: Place the thermometer inside your oven before you close it, so you can check the temperature.
Step 10 Use oven mitts or potholders to open up the lid of the pizza box by lifting the glass dish out of the oven.
