If you are a teacher of grades 1 or 2, then you might want to apply for a batch of free Lysol Minilabs Science Kits. Here's their own description about this freebie:
Lysol's HERE for Healthy Schools program is intended to help stop the spread of illness-causing germs in the classroom through creating hands-on activities that are fun and engaging while teaching the science of germs, and positive hygiene behaviors. Designed for grades 1 to 2, these kits are designed to educate students about the science of germs and encourage healthy hygiene habits. Each participating classroom will receive one kit with three modules for the school year. Each module includes hands-on materials for the whole classroom, engaging and fun hands-on lesson plans aligned with NGSS, ELA, Health, and TEKS standards, and resources for teachers for easy and effective implementation.
You only have until July 31, 2025 to request this. Selected educators will be notified by August 20 and they'll receive their kits sometime in September.
It seems they're also still offering a Lysol Welcome Back packs for teachers.
