Product Description

How can we visualize molecular movement and correlate this with diffusion and osmosis? How does diffusion change with temperature? Once substances have diffused, do they ever separate? Students watch diffusion using food coloring and different temperatures of water. This is a great introductory lab before you begin to study diffusion and osmosis in more depth.


By starting with the scientific phenomena, you'll be intrigued and excited to dig deeper into the why’s and how’s of each scientific concept. Beautifully illustrated and well laid out, these lab activities are easy to use from the very first page. Experiments are clearly organized and written to the student so they do not need to be pre-digested by a teacher before beginning. Helpful tips throughout the experiments and the Teacher Notes leave the reader in no doubt about how to perform or understand an experiment. Designed for students and optimized for teachers, these labs will engage and fascinate students. Scaffolded writing prompts allow students of different abilities to engage with the same content. Both the teacher and the student are addressed so no additional books are needed. Engaging Science Labs are useful for classroom or homeschool environments.


Concepts Addressed:
• Molecules are always in motion; this motion drives diffusion.
• Molecular motion changes with temperature; increasing temperature causes increased motion.
• Over time, two fluids will become completely mixed.
