Density

Explore solids and liquids with the classic density tower. After discovering the density of liquids, kids can test how dense certain solids are. Which solids sink? Which ones float? Click here for the explanation. If you want to make a smaller tower, you can experiment with the 7-layer density column here. You can adjust the colors of your 7-layer density column and make a rainbow tower! You can also integrate math with this activity and practice fractions! For younger kids, you can concoct…

They are related by the the density triangle. They are related by the the density triangle. d = m/V m = d×V V = m/d DENSITY Density is defined as mass per unit volume. d = m/V Example: A brick of salt measuring 10.0 cm x 10.0 cm x 2.00 cm has a mass of 433 g. What is its density? Step 1: Calculate the volume V = lwh = 10.0 cm × 10.0 cm × 2.00 cm = 200 cm³ Step 2: Calculate the density d = m/V = (433 g)/(200 cm³) = 2.16 g/cm³ MASS d = m/V We can rearrange this to get the expression for the…

Little scientists can learn about a fundamental concept of physical science with this worksheet all about density!

Show your child that the simplest ingredients (salt and water) can be used to illustrate the concept of density!

Rainbow Density Experiment

Creepy density tower. Use liquids with different densities to float on top of each other and find a spooky object for each layer.

Hi everyone! This year my students absolutely love science! Each morning they ask "What experiment are we doing today!?" and then sound d...
