Science & STEM Ideas for the Entire Year

I love incorporating science experiments and STEM challenges into my lessons!  They are so engaging and meaningful for my students and thus create a love and excitement for learning.  In addition, my students’ are applying problem-solving and critical thinking skills as well as math and literacy skills as they observe, record, reflect, and write about their observations.

Because of these many benefits, I have found many times throughout the year to add science & STEM to my curriculum.

Here are some favorite ideas that you can easily add to your existing lesson plans throughout the school year or if you would like ready-made science lessons for the year click here.

“This is an outstanding unit! Everything is clearly laid out. The recording sheets are wonderful! I especially like the “Apple Science and Stem” theme and can’t wait to use it next year! Thanks so much!” – Sandra B.

“I have loved these activities but my students have loved them even more. We completed the Christmas experiments the whole week before winter break. My students looked forward to each activity and walked into the classroom each morning wondering what the day’s experiment would be. I have used experiments from some of the other files throughout our curriculum and those have gone just as well. What a great addition to my science resources!” – Lindsay L.
