This is a modified excerpt from STEM Design Challenge: Flower Frenzy.

Note: Flower Frenzy is also available in the Valentine’s Day 5-in-1 STEM Challenge Olympics Bundle (2nd – 8th).


The basic premise:

Individually or in partners/groups, students will design and build one or more floating flowers.

Multiple iterations are recommended to get the most student benefit, but this can also be treated as a one-off activity.


Benefits of this STEM Design Challenge:

- Focus on critical thinking, problem solving, and application of learning

- High levels of student engagement

- The potential to hit upon all NGSS ETS standards depending on the depth and number of iterations you choose to implement in your classroom (modifications included)

- Highly flexible and differentiated for materials, timing, grade levels, and rigor.

Each design iteration should be planned for at least 45 – 60 min. if you are including data gathering and analysis rather than just building for fun. If you add extension activities, you will need to adjust timing accordingly. I recommend working on STEM Design Challenges in multiple iterations to get the full value.


Materials you’ll need to do the activity are easily modified.

Sample/suggested materials for each student or group:

– Colored tissue paper and/or construction paper (5+ pieces)

– Straws (5 - 10)

– Pipe cleaners (5 - 10)

– Plastic baggies (1-2)

– Tape (24 in.)

– Rubber bands (5 - 10)

– Bucket with water (to test floating flowers)

• Foil (1-2 small sheets)

• String/yarn

• Craft sticks (5 – 10)

• Cardboard (scrap pieces, equally distributed to groups)

• Paperclips

• Brass brads

• Small cups
