DISCUSS (1 of 2):

Imagine power is out for a day. How would that affect your life? (For example: What things stop working? What things do you lose the ability to do?)

DISCUSS (2 of 2):

Now imagine power is out for a week (or even a year). What are some ways this might affect your life?

DISCUSS:

Besides making things move, what else can electrical energy do? (Think about examples from the story.)

“Students LOVE their flashlights. This was such a fun hands on activity. ”
“Kids loved making the flashlights and figuring out how to make a switch!”
“My boys in my behaviour class were glued to the lesson and our discussions were rich. They loved creating the flashlight. I loved when they were experimenting with the LED light and battery and they were able to get the light to glow. Their faces lit up!! Everyone helped each other. I was very proud of them.”
“The students loved the hands on activity where they were able to create flashlights. They were incredibly engaged!”
“The wonder in the eyes of fourth graders as they make their own flashlight was awesome!”
“The lab was the best part! It had minimal supplies needed with minimal money needed to be spent, yet provided the student with a neat take home!”
“This was so easy to use in the classroom and the students loved it!! Best lesson I have found to help teach younger children (4th grade) about electricity!”
“Super engaging lesson! So easy to follow with minimal preparation or materials. Thanks!”
“My students loved making the LEDs light up! Overheard great conversations between students helping each other and discussing what was happening! Wonderful lesson!”
“Kids loved it, just watching their eyes light up when they were successful....the reason I teach!”
“My students LOVE that they get to design and continually improve their own flashlight. Thanks for such an engaging investigation!”
“The excitement the children had while experimenting!”
“Fantastic introduction to energy and electricity. Thanks for the great videos and doable activities. My kids loved this and I loved teaching it!”
“Fun hands on activity, easy to do but still requiring thinking and evaluating results.”
“Your guys' site is one of the best laid out, well thought out, organized teacher sites I've ever been on. It is user friendly. I love the way there are so many usable links I can just click on in extras without having to spend hours researching! This lesson was particularly amazing. And kids were super engaged.

In this lesson, students are introduced to electricity as a form of energy. In the activity, Build a Flashlight, students investigate how electrical energy requires a circuit and make their own mini flashlights from LEDs, button batteries, and strips of aluminum foil. Along the way, they’ll learn about the anatomy of a battery, begin to see how circuits work, and discover how handy an on-off switch can be.
