An investigation into change of state where students make silly putty.
NC State University
The Engineering Place: Ice Cream in a Bag
An investigation into change of state where students prepare small bags of ingredients and shake them within a bag of ice and salt to see if they can make ice-cream. As they progress, they apply the scientific method.
E-learning for Kids
E Learning for Kids: Science: Netherlands: What Are Permanent and Temporary Changes?
In this lesson, students match a substance with its state of matter, identify what state something is, and learn about temporary and permanent changes in matter.
Starfall
Starfall: All About Matter
This lesson focuses on Matter including the three states of matter, the energy that it takes to change the state of matter, and experiments for children to conduct. Students can choose to have any paragraph read to them.
