Description

Our Blob-a-Lamp is more than a mesmerizing motion light - it's a complete lesson on density! At room temperature, the colored wax blobs are denser than the liquid. But turn the lamp on and soon enough, the questions begin: which material really is denser - the liquid or the wax blobs? What makes the blobs rise? Why do they then descend back toward the lamp's base? And what does the incandescent bulb in the lamp's base have to do with any of this? Students at all grade levels will be engaged by this retro object, and are sure to be eager to learn about heat, expansion and density. About 13" tall. Colors may vary.

I ordered this item, thinking it would be blue, but it ended up being pink.

It took a while to heat up but once it got going it was a flash back to the 70's. I had it in the back ground during a volcano lava demo and it set the scene perfectly. Like!

It is perfect for teaching density, conduction, convection and radiation. I refer to it all of the time.

Density!

It took a little while for the waxy blobs to melt, but once they did, it was awesome! My kids could sit and watch for the entire class period. We used it in our study on Earth movements and specifically volcanoes. Great lesson on density. Thanks, EI!

May be normal but it gets extremely hot. Be very careful around children. Mine has some kind of trash in the liquid that distracted from the beauty of the lamp.

Owner Response: Hi Larry, You are correct. The lamp does get very hot, and that is normal. If your lamp is not perfect, please return it for a replacement. We want you to be perfectly happy with your purchase.

NGSS

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

Elementary Middle School High School

2-PS1-1

Students can use the Blob-a-Lamp in an investigation to describe and classify different kinds of materials by their observable properties.

2-PS1-2

Students can analyze data obtained from testing the Blob-a-Lamp to determine which materials have the properties that are best suited for an intended purpose.

5-PS1-1

Students can use the Blob-a-Lamp in an investigation to develop a model to describe that matter is made of particles too small to be seen.

5-PS1-3

Students can make observations and measurements of the different materials in the Blob-a-Lamp to identify materials based on their properties.

MS-PS1-1

Students can use the Blob-a-Lamp in an investigation to develop models to describe the atomic composition of simple molecules and extended structures.

HS-PS1-1

Students can use the Blob-a-Lamp in an investigation to predict properties of elements. Students can use the Periodic Table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

HS-PS2-6

Students can use the Blob-a-Lamp in an investigation to communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.

Suggested Science Idea(s)

This Blob-a-Lamp is an awesome demonstration for density, solubility, miscibility and the salting effect. All students will be amazed by the actions the beads take. Due to the unexpected results in the bottle, secondary students have to use science to dissect an explanation for the layering. Great inquiry opportunities for all students. Some teachers never give away the secret.

Students can use the Blob-a-Lamp in an investigation of density. Shake up the bottle and let them sketch the various motions of the beads. For primary grades, a second bottle can be prepared with some food coloring added to the water solution, to bring a more concrete explanation. Secondary students may be able to use chemistry to decipher the paradox.
