Chaining Paper Clips: Science, Technology, Engineering, and Mathematics Task
The Paper Clip Chain STEM challenge is an engaging and educational activity that encourages kids to explore engineering principles using a simple household item - paper clips. This challenge is suitable for children in Grades 2-3 and Grades 4-6.
To start the challenge, gather the necessary supplies: paper clips, a bucket or basket with a handle, coins, marbles, or rocks, scissors (optional), a scale (optional), and construction paper (for an optional paper chain STEM challenge).
The first step is to secure one end of the paper clip chain to the handle of the bucket. Once the chain is established, it's time to test its durability. Step 3 suggests keeping the weight steady for at least one minute to ensure the chain's strength.
Adding weight to the bucket is done by starting with coins, marbles, or rocks and keeping track of the weight the paper clip chain can hold. This step helps children understand the importance of testing and improving their designs.
Step 4 involves testing and improving the design by trying different paper clip arrangements and observing which one holds the most weight. This step encourages problem-solving and thinking like a scientist.
As an extension for older kids, learning about the engineering design process steps can help extend the activity. STEM reflection questions include discussing challenges faced during the chain building process, the strongest way of connecting paper clips, the effect of chain length on its strength, potential materials for a stronger chain, and comparisons to real-world engineering challenges.
The challenge can turn into new challenges as you experiment with stronger structures. Step 5 also encourages experimenting with other materials such as pipe cleaners, binder clips, or clothespins.
In addition to the Paper Clip Chain STEM challenge, there are several other suggested activities like the Floating Paper Clip Experiment, Penny Boat Challenge, Spaghetti Marshmallow Tower, Marshmallow Toothpick Tower Challenge, Strong Spaghetti Challenge, Egg Drop Challenge, Paper Bridges, Cup Tower Challenge, and the 3 Little Pigs Architecture Project.
For leftover paper clips, there are additional experiments suggested such as the floating paper clip experiment and the paper clip surface tension in a glass. For those interested in more STEM activities, a printable engineering and STEM pack containing 80+ doable engineering projects is also mentioned.
The Paper Clip Chain STEM challenge is not only a fun activity but also a great way to encourage children to think creatively, solve problems, and develop their engineering skills.
