If you are like me, then you have a big container of recycled materials and cool items you can't bear to get rid of! That's exactly how we built this hand crank winch. Using recycled items for STEM projects is an awesome way to re-use and re-purpose common items you would normally recycle or throw away. This simple machine for kids is a fun STEM activity to try!

HOW TO BUILD A HAND CRANK WINCH!

SIMPLE MACHINES FOR KIDS

Building simple machines with kids is a great way to show them how stuff works! Our winch craft is truly an easy STEM activity with big impact.

Using recycled items to make cool things allows awesome STEM challenges to be accessible to ALL kids! Plus any activity that uses recycled materials is great for the environment!

HOW TO MAKE A CRANK WINCH

YOU WILL NEED:

Cardboard Tubes

Spool {can be optional, see below}

Straw or Pencil

String

Tape, Scissors

Small Basket {object to attach to string}

HOW TO BUILD A HAND CRANK WINCH

Here's the picture diagram of the four major steps to building this winch simple machine. I will describe the steps below the picture.

Tape 2 cardboard tubes to a solid surface. Use your straw as a reference tool for how far apart they should be placed from each other.
STEP 1
Make 2 cuts at the top of each cardboard tube just big enough of the straw or pencil to rest and be able to spin.
STEP 2
Put your spool on the straw or pencil. Now if you don't have a spool, you can simply secure your rope to the straw or pencil with a piece of tape. You still have a hand crank winch! If you do use a spool make sure to secure it with tape to the straw or pencil. What if you don't secure it? The spool just spins around the straw and there is no ending up of string! We learned this concept with our rubber band car too!
STEP 3
If you are using a straw, you can even thread another straw into it and use the bendy part to make a handle!

Secure your rope or string to spool with a piece of tape {or to straw directly if you don't have a spool} and tie your basket or object to the bottom of the string.
STEP 4 Looking for easy to print activities, and inexpensive problem-based challenges? We have you covered...
Go ahead and test out your hand crank winch simple machine. What can you pull up with it? Do you think it makes lifting heavy things easier. Another great idea is to test out a pulley simple machine!

A simple machine such as this winch is used to raise and lower weight. An example of a winch that is pretty easy to get a picture of is a bucket in a well!

He chose to sketch his simple machine all on his own.

Building simple machines with kids is tons of fun and gives them a great chance to troubleshoot problems and come up with creative solutions. Raid the recycling bin to make your simple machines this year. Building machines makes an awesome STEM challenge for a variety of age groups too.

Make a homemade spectroscope with a few simple materials and explore the spectrum of different light sources. You'll see all kinds of rainbows! This science activity for kids makes a great addition to a unit on light or weather and is perfect for St. Patrick's Day too!

Light experiments are always fun, especially when they involve rainbows! In this science activity kids will make their own spectroscope- an instrument used to split light into different wavelengths, which we see as different colors of the rainbow. (This post contains affiliate links.)

Materials for Homemade Spectroscope

Empty paper towel roll

Craft knife and/or scissors

Blank or old CD

Pencil

Small piece of cardboard or cardstock

Tape

Paint (optional)

Making a Homemade Spectroscope

1. If you'll be painting your paper towel roll, you'll want to do that first and let it dry. (This step isn't necessary, but it's hard for us to pass up an opportunity to paint something!)

2. Use a craft knife (an adult should do this) to cut a thin slit at a 45° angle toward the bottom of the cardboard tube.

3. Directly across from the slit, make a small peephole or viewing hole using your craft knife (another step for an adult).

4. Trace one end of your paper towel roll onto your small scrap of cardboard or cardstock. Cut it out.

5. Cut a straight slit right across the center of your cardboard circle.

6. Tape the circle to the top of your spectroscope.

7. Insert the CD into your 45° angled slit with the shiny side facing up.

Using the Homemade Spectroscope

Start by taking your spectroscope outside. Point the top slit up at the sky (NOT directly at the sun). Look through the peephole. You will see a rainbow inside!

Now try your spectroscope with other light sources like fluorescent light, neon light and candle light. Compare what you see!

What's going on?

A CD is a mirrored surface with spiral tracks or pits. These tracks are evenly spaced and diffract light (separating the colors). Because the CD's surface is mirrored, the light is reflected to your eye.
