Students apply knowledge about density of solids from previous experimentation to this activity which they investigate the density of liquids. They work in small groups to mix water and syrup, and water and oil to see what occurs....

Students investigate different liquids to develop their concept of a liquid. They work at a center to tip, swirl, shake, roll, and otherwise investigate seven liquids in small, clear plastic bottles: plain water, corn syrup, liquid...

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. 

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

In this density worksheet, students modify three film canisters in order to make one float in a tank of water, another suspend in the middle of the tank, and the third should sink to the bottom. They collect data on their canisters and...

First graders write with his or her pencil on a worksheet created by the teacher his or her prediction of whether each part of a pumpkin will sink or float. They drop each of five objects in the water one at a time allowing enough time...

Students explain that some things can float on top of water because of what we call "surface tension." They see that if something happens to disturb these water molecules from tugging on each other, the skin-like surface breaks up.

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 examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...

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...

Students draw upon their prior knowledge of the density of water and practice writing a hypothesis, making an observation, and analyzing data while watching a density demonstration.

In this vocabulary activity, students circle the letter of the word or phrase that means the same as the word in bold in 10 sentences.

Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...

Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...

Learners perform experiments to examine whether trash can float, blow around, or wash away. The effects of these characteristics on the presence of marine debris in the environment are then discussed.

First graders write about vehicles that float.

Students participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.

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 create a Cartesian diver out of a bottle of water and a condiment packet (soy sauce, ketchup, etc.) They observe what happens to the packet as they squeeze the bottle and determine which types of condiment packets make the best...

Students end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.

First graders develop skills of scientific inquiry. They determine which objects float and which sink.

Students examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.

Archimedes' principle is practiced as chemistry learners practice computing the density of different gases, liquids, and solids. Using a chart of standard densities, they also identify unknown materials by similar calculations. Fifteen...

Students participate in a hands on activity simulating an oil spill. In this oil spill lesson plan, students conduct an experiment about an oil spill, discuss how it would affect the environment and provide solutions to prevent oil spills.
