Make a Spooky Glow-in-the-Dark Lava Lamp

Making “lava lamps” is a fun STEM activity for kids that is also just fun. In general these types of projects are made by mixing oil and water along with some other ingredients, which provides a good opportunity to talk about why oil doesn’t mix into water.

But there are lots of ways to make different kinds of lava lamp like projects. I especially like this glow in the dark version from Science Kiddo, which also allows you to talk about how glow in the dark things work.

(Short answer: components of the glow-in-the-dark material are phosphors, which are charged in sunlight and then emit the light back in the dark.)

This one also uses fizzy tablets so you get fizzy glow in the dark stuff. How fun!

St. Patrick's Day STEM Project Ideas

The celebration of Our Lady of Guadalupe is important throughout Mexico and other parts of the world. Her feast day is Dec. 12, and the celebrations honoring her appearance to Juan Diego in 1531 begin a few days before that.

Whether you celebrate yourself or just want to share about the celebration at home or in your classroom, Las Mañanitas: The Beautiful Celebration of Our Lady of Guadalupe is a good place to start. The book, by Ernesto Joel Vega Rosales and Jeanette Gonzalez Seneviratne, with illustrations by Dana Sanmar, tells the story of a family’s celebration of the feast day in both English and Spanish.

They prepare with a novena, which is nine days of prayers and preparations. The children, Lucia and Pablo, are given special outfits made by their grandmother that look like what Juan Diego might have worn when he saw Our Lady. The book describes the prayers that are made each day, such as a prayer for respect for life, for families and for the indigenous people of the Americas, to name a few.

As told in the book, Juan Diego was a native Mexican born near modern day Mexico City. His given name was Cuaauhtlatoatzin, which means “He who speaks like an eagle.” When he converted to Christianity his name was changed to Juan Diego, and as he walked to church he passed a hill called Tepeyac. One day he heard the birds singing especially beautifully and a voice called him to go to the top of the hill.

There he saw Our Lady of Guadalupe, who asked him to tell the bishop she wanted a chapel built in her name at the foot of the hill. The bishop asked for a sign that Juan Diego really saw her, and later she had him collect flowers that she blessed and take them to the bishop. When Juan Diego dropped the flowers, an image of Our Lady could be seen on his cloak, which is still on display in her basilica to this day.

The feast day is celebrated as mañanitas, which includes singing, indigenous music and dancing, and children presenting flowers to Our Lady. Juan Diego is remembered today as being humble, brave and faithful, and was the first indigenous American made a saint.

The book is colorful and tells the story in a clear way, and it’s fun to have it both in English and Spanish if you teach Spanish or speak Spanish at home or in the classroom. It’s a great way to learn the basics of the celebration and the story of Juan Diego and why he is still remembered today.

About the book: 40 pages, paperback, published 2024 by Loyola Press. Suggested retail price $14.99.
