Overview This experiment shows how certain substances can change the surface tension of water — and when they dissolve unevenly, they can actually push themselves across the surface. The result looks like tiny, fast-moving “color boats” zooming around your bowl. Materials You will need: A few drops of liquid food coloring A small plate […]

Overview This is one of the most dramatic ways to show students how surface tension works. It looks like magic when pepper suddenly rushes away from your fingertip — but it’s really science in action. This activity works beautifully during lessons on liquids, molecules, and forces on the surface of water. Materials You will need: […]

Overview This classic experiment looks like magic — a candle goes out and water rises inside an upside-down jar. Many people think the water rises because the flame “uses up all the oxygen,” but that explanation is not quite right. This modern version shows the real science behind what’s happening: expanding and contracting air. Materials […]

Melting Ice Experiment Overview This surprising experiment—featured on Good Eats with Alton Brown—reveals how heat transfer, insulation, and moving water affect how quickly ice melts. Students often predict that boiling water melts ice fastest, but the results challenge their expectations. Objectives Students will: Make predictions and test a hypothesis Compare the effects of still hot […]

  Lesson 213 – Based on ideas by: Randi Austin, Kindergarten Teacher Overview This activity gives children a delicious hands-on way to explore color mixing using white icing as paint and pretzel sticks as “brushes.” Students experiment with primary colors and discover how new colors are created. Objectives Students will: Explore and identify the three […]

Lesson 214 – Based on Ideas by Debbie Haren, Preschool Teacher Grade Level: Preschool Objectives Children will: Identify and name common feelings Recognize facial expressions that match emotions Express their own feelings through art Build vocabulary for social–emotional learning Practice sharing and discussion Materials Small paper plates (4 per child) Popsicle sticks Markers or crayons Glue Optional: […]

“Active Reading” Lesson 4944 • By Elizabeth Thompson (Expanded Version) Grade Levels: Preschool, K, 1–2 A full menu of outdoor literacy activities to reinforce alphabet knowledge through play, movement, and sensory exploration. Learning Objectives Students will: Reinforce letter recognition through multi-sensory, kinesthetic activities. Connect letters to environmental print and real-world objects. Strengthen gross motor coordination […]

Learning Objectives Students will: Understand what overrun is in ice cream (the amount of air mixed into it). Compare volume vs. mass by weighing ice cream containers of the same size. Observe how melting separates air from liquid in ice cream. Explore how air affects texture, weight, melting, and even the price of ice cream. […]

Learning Objectives Students will: Observe how condensation forms on the outside of cold containers. Compare condensation on two different liquids (water vs. soda). Learn how carbonation and insulating bubbles affect temperature transfer. Practice scientific skills: predicting, observing, recording data, and explaining results. Understand how temperature differences create condensation. Materials 2 regular drinking glasses (not insulated) […]

  Lesson 224 • By Debbie Haren (Expanded Version) Grade Level: Preschool, Kindergarten Learning Objectives Students will: Recognize their own name in print. Identify the letters in their name and the order they appear in. Build independence in morning routines. Strengthen letter–sound awareness when discussing names. Develop a sense of classroom belonging and identity. Materials […]
