Featured Reviews

“Was a fantastic way for students to work with one another. As a teacher, I loved seeing their creativity come out as they worked together to problem solve every time they added another step to their machine! This will be an activity we come back to later in the year as a fun review!”
· Anthony · Teacher
“The kids loved when their chain reactions finally worked! And they loved going step by step with Doug's video. Thanks!”
· Stephanie · Teacher
“The students were incredibly engaged and the conversations they were having about energy were unreal! This was my favorite lesson by far (so far...!)!”
· Kelli · Teacher
“It was awesome- everyone was active and the discussions were spot on to make the chain reaction work. This one was strong for team work as well as science understanding. ”
· Linda · Teacher
“Amazing experience. My students loved the chain reaction machines and have a great sense of potential vs. kinetic energy and the energy transformations that take place within their machine!”
· Brenda · Teacher
“After Mystery 4 and 5, the students were so excited to see what else they could add on to their chain reactions. They loved exploring with different materials. These lessons provided the foundational skills to get it all started.”
· Sarah · Admin
“The students liked the challenge of finding ways to transfer energy throughout the system. Very motivating lesson that promotes higher order thinking.”
· Betty · Teacher
“My students loved this activity. They had laser focus on their design and creativity was incorporated. Very exciting. They seemed to truly understand stored energy. ”
· Joan · Homeschooler
“This was an amazing way to incorporate the engineering design process into the unit! My class was so engaged, willing to try new things, and discussing science concepts at the same time! ”
· Robbie · Teacher
“This was so much fun. They learned a lot about problem solving and energy transfer.”

Prep Instructions

We suggest students work in pairs. Homeschool students can work on their own.

Plan Ahead

To complete this lesson, students will need the ramps and levers they built in the previous lesson.

Students can also add a variety of materials to extend their chain-reaction machines. You can ask them to bring things in, or gather some basic materials to keep in the classroom. See the list below for items we recommend having on hand. Or, for more ideas, watch "Inspiration for Chain Reaction Builders" in Extensions before you start this activity to see some possibilities.

  • Extra printouts of the “Chain-Reaction Starter Kit” handout from the previous lesson (in case students want to make more ramps)
  • Card stock for making custom-built ramps
  • Paper cups to serve as ramp supports
  • Books and boxes to add height
  • Dominoes or objects that will topple like dominoes (dominoes built of LEGO bricks, cassette tapes, paperback books, markers standing on end, etc.)
  • String
  • More stickers
  • Things that roll (empty cans, toy cars, rubber balls, markers lying down, toilet-paper tubes)
  • Unconventional ramps (like empty binders)

Make Sure You Have Enough Space

Each Chain Reaction Machine will take up several feet. Each student or group of students will need a table or several desks pushed together as a work space.

Classroom Management Tip

Marbles are very fun, but can be very distracting! We suggest waiting to distribute marbles to students until Step 14 of the activity.

Discussions

Discussion

This video will show you that ramps, rolling balls, and falling sticks can do some amazing tricks. Here are things to watch for and talk about.

  • Ways to start balls rolling. (Some may surprise you!)
  • Ramps that are levers. (What makes them move?)
  • Unexpected ways to add energy to a rolling ball

Does this video give you ideas for your own chain reaction?

Inspiration for Chain Reaction Builders

Inspiration for Chain Reaction Builders

Here are some images and short videos from Pat to get you thinking.

  • Dominoes: Many objects can serve as dominoes.
  • Rollers: Marbles are only one kind of roller.
  • Ramp #1: A binder makes a great ramp.
  • Ramp #2: Make custom ramps from cardstock.
  • Ramp #3: Two rulers make a ramp.
  • Ramp #4: Make marble ramps on your bulletin board.
  • Other Ideas: Doug and Pat talk through adding steps to their chain reaction machine.

What ideas do you have for using everyday objects in your chain reaction?
