STEM + Families

Promote STEM Education and Host a Science Festival

The STEM + Families Science Festival program, sponsored by Bayer, aims to:

  • Empower PTAs with information on hosting hands-on science experiments that bring students and families together
  • Provide families with ready-to-go experiment and family guides
  • Help all kids experience and explore activities and careers in STEM

PTA’s vision is for all students to have the family and community support they need to access and pursue opportunities and careers in the STEM fields.


Host a STEM + Families Science Festival Program


We encourage local PTAs to host a STEM + Families Science Festival Program to promote opportunities for families to participate in shared, hands-on science activities and to inspire kids and families to pursue careers in STEM! 

National PTA offers In-Person and At-Home program models to meet students and families where they are. Work with your school community and your administration to determine which program model is best for your PTA.

Programs Where You Are

Local PTAs are encouraged to select PTA Programs and program delivery models based on the unique needs of their school community.

Each program is flexible and offers free technical assistance leader-to-leader learning opportunities and “drag and drop” materials necessary for success.


National PTA Programs In Person

Be sure to refer to current CDC guidance to host an In-Person model.


National PTA Programs At Home

At-Home models are further divided into three delivery methods:

Real Time Icon

Self-Paced Icon

Tech-Free Icon

Science Festival experiments are divided into three main categories. Each experiment includes easy-to-follow steps that engage families and students and provide families with ready-to-go science resources.


  • Biology: Structure and Function

  • Materials Science: Energy and Matter

  • Chemistry Cause and Effect

STEM + Families Science Festival Program In-Person Toolkit


PTAs may elect to host In-Person Science Festival events to bring together students and families to participate in shared, hands-on science experiments and to promote career opportunities in STEM fields. This toolkit includes helpful how-to documents and sample templates that you can use to make planning an In-Person Science Festival easy. Potential hard costs: Experiment materials, inclusive promotional materials, refreshments, gift certificates.

This toolkit includes helpful how-to documents and sample templates you can use to make planning a STEM + Families Science Festival easy.

You can also download this Hosting a STEM + Families Science Festival From Start to Finish Guide, which includes the same information as the toolkit all in one PDF.

STEP 1: Plan Your Event 

Form a planning committee by inviting parents and teachers of STEM subjects to join. Recruit at least 10-15 volunteers to help during the Science Festival. Organize your tasks, create a budget and schedule deadlines. Reach out to local partners to gain donations and community volunteers.

General Planning

Choosing Experiments

In addition to the Experiment Guides provided for the volunteers to use at the experiment stations, we have also provided Family Guides with experiment instructions for adults and family members to use at the experiment stations.

Getting Volunteers

Hosting events like this is also a great way to recruit new PTA members! Consider having recruitment flyers like this one at your event.

STEP 2: Promote Your Event
STEP 3: Host Your Event

Ensure that everything goes smoothly at your Science Festival! Offer take-aways to parents who attend to help them retain and build on what they learned.

STEP 4: Wrap Up

Be sure to thank your PTA, school staff, community partners and parent volunteers. Gather feedback, report your results to National PTA and use the findings to plan your next event. National PTA recommends offering an incentive for completing the survey (e.g. enter names into a drawing for a $50 gift card donated by a local merchant).


STEM + Families Science Festival Program At-Home Toolkit


PTAs may elect to host a virtual Science Festival at home. At-Home models are offered as three method types: Real-Time, Self-Paced or Tech-Free. Your PTA can offer one model, a combination of two models or even all of the models to your families. Choose what works for you—each model has strengths and limitations.

Potential hard costs: Experiment materials (if distributing to families), inclusive promotional materials, gift certificates, virtual platform.

Real-Time Program Model

This live virtual program builds conversation, community, and learning.

Self-Paced Program Model

The program happens at home, and families conduct the experiments on their own time and at their own pace.

Tech-Free Program Model

In this model, events happen without a device, videos or support technology. This option may be helpful for families with limited devices or for families experiencing virtual fatigue.
