National Day Calendar Classroom - Week 36 - April 28, 2019

CLASSROOM | WEEK 36 | April 28, 2019

National Zipper Day on April 29th leads the classroom into a study about simple machines. It’s an excellent way to introduce more STEM and STEAM to your students. Simple machines open up fun ways to experiment, too! We’ve provided a basic worksheet with questions to stimulate conversation.  We also link you to projects to either send your pupils exploring or to do right in the classroom. 

As always, the classroom includes puzzles and trivia to keep things interesting. The archive contains projects from previous celebrations, so be sure to check those out, too. 

Sharing on social media isn’t required; learning is. But if you do, please use #NDCClassroom to share on social media.

LESSON 1 National Zipper Day

We use simple machines all day long without even thinking about it. The zipper is just one of thousands of them. 

There are six basic simple machines. They are the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw. We use them every day to make difficult tasks easier. We’ve included a pdf outlining these with questions to get the classroom discussing. 

LESSON 2 – Simple Machine Projects

Put Six Simple Machines All Together
