Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Begin with an introduction to famous deep-sea submersibles. Learners work in groups to gather information on different vessels and then share with the class. Each group then uses water displacement to help calculate the density of...

Students study the properties of the physical and natural world. In this properties of the physical and natural world lesson, preschool students work at discovery tables to see how simple machines work, what happens when items are put...

Students will make a lava lamp. In this density lesson, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

Students examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...

Students extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing of ships. students discover that most ships are constructed very similarly-whether they are schooners or destroyers.

Students engage in this, the third in a three-part series on ships. The overall lesson series is designed to allow students to extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing...

Match animals to their environments with a cute lab activity. Kids draw a line between each animal, such as a fish, a rabbit, and an ant, to the place where it lives. For hands-on practice, a science investigation instructs learners to...

Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity: Carbon dioxide gas is more dense than air Bubbles are semipermeable, allowing only carbon dioxide to diffuse...

Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

This particular lesson was written by the National Earth Science Teachers Association, but density is a concept that you can teach at the beginning of the school year in your life, physical, or earth science classes. It would be fun to...

Study how plants grow with your English language learners with a cross-curricular lesson plan revolving around pumpkins. These activities provide opportunities to practice new scientific vocabulary while practicing skills such as...

Students experiment with floating the spaghetti, the gas functions like a life preserver. Pupils comprehend that a person is slightly more dense than water. They comprehend that a life preservers are made of low-density materials. The...

Students investigate how plants grow by analyzing pumpkins. In this agricultural lesson, students read The Biggest Pumpkin Ever by Steven Kroll, and draw pictures of a pumpkin in each of its growing stages. Students measure and dissect...

Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..

Students identify the various states of water and its natural flow downward. As a class, students take digital pictures of different forms of water and create a multimedia presentation describing their photographs. Groups of students...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

Sixth graders develop an understanding of floating, sinking, density, and buoyancy and apply it to the design of testing of ships.

Learners perform experiments to examine if debris float, or blow in the wind. The effects of these characteristics on the marine debris are then discussed. They determine how a material can influence what becomes marine debris.

Some microbes are beneficial for humans. This resource asks learners to identify beverages that contain healthy microbes. There are six beverages shown, and pupils must place a check mark next to the ones they think contain healthy...

Students comprehend that Carbon dioxide gas is relatively easy to generate. They comprehend that one way to produce it is with dry ice. Pupils comprehend that carbon dioxide gas can also be produced by combining baking soda with vinegar.

Young scholars conduct an experiment to simulate an oil spill and identify the characteristics of oil in water. They evaluate the effectiveness of various cleanup methods. They discuss the how to clean up an oil spill, and what causes...
