Today we did a very exciting activity. We made model lava lamps to help us learn about density. We combined two liquids with different densities, and then added alka seltzer tabs to watch them bubble. We even held them over flashlights to help them light up. We learned that water is more dense than oil … Continue reading Lava Lamps Teach Us About Density
On Tuesday, we completed an activity to learn more about what density means. We learned that density is how closely packed molecules are together in an object (how much space they take up). In the future, we will learn how to calculate density. The students built a lava lamp by combining 2 different liquids of … Continue reading Density and Lava Lamps
Today we built “lava lamps” in science class to learn about the density of different liquids. Here is a video explaining the process if you would like to make one at home. Lava Lamp Instructions Here is an extension activity for layering multiple liquids. Layering Multiple Liquids
We are in a very exciting time in science right now! Students just completed chapter 1 and are wrapping up the unit with an experiment with pendulums! We found a very interesting video all about pendulums and I want to share it here: Pendulum Wave Video Students are testing what changes the number of times … Continue reading Ending with Pendulums and Starting with Lava Lamps!
