In this chemistry worksheet, students locate twenty seven terms in a word search. Answers to the puzzle are available in various formats.

Seventh graders are given the opportunity to use model-building as a way to help comprehend the forces and phenomena at work in the world around them. They use both successful and unsuccessful models to make inferences, refine...

Fifth graders define density as the amount of mass per volume a material contains, compare the densities of several types of materials, especially those that sink in water compared to those that float. They use two different methods to...

Students watch as the teacher demonstrates: if a single liquid is placed in a U-shaped tube, the level of liquid on both sides are the same. When the mass is greater on one side than the other, liquid is pushed from one side to the...

Students (teachers) complete the activity, they should not come in contact with Alka-Seltzer. They comprehend that the density of a gas can be calculated from its mass and volume. Pupils calculate the volume of gas generated by...

Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Students calculate the volumes of regularly shaped objects from measurements of their dimensions. They use several formulas and measure different objects to calculate the density, volume, and mass of the objects selected or assigned.

Students have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...

Students comprehend that the Cartesian diver is a dropper and the water and air inside it. They vary the volume of the air and the amount of water, the diver can be made to be either more or less dense than water. Pupils squeeze the...

Students comprehend that hot water rises up through cold water but cold water does not rixe in hot water. They comprehend that water at temperatures above 4oC decreases in density with increases in temperature. Students answer lab...

Students practice determining liquid densities in a short, hands-on lab activity. Students use a graduated cylinder to measure out 100 milliliters of a liquid, find its mass using a balance, and record measurements in a data table....

Students look at clippings of boats. They are able to define the following terms displacement, and density. Students construct a clay boat. After they complete their clay boat students answer questions about their clay boats.

Seventh graders explore the the constituents and properties of matter. They use the scientific process while exploring solids, liquids, gases, the mass, volume and density of matter. Students plan and conduct an investigation to measure...

Students discuss the each of the following objects/substances in terms of what contributes to their density: 1) a piece of copper; 2) a piece of bread; 3) steam in the air. They evaluate the causes in the various densities of substances.

Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.

Fourth graders examine various types of rocks and record their properties. They collect rocks at home and bring them to school where they are mixed and distributed to groups of students. After writing their observations on...

Young scholars examine how circulation currents of the ocean. They use a tub of hot and cold water to demonstrate the currents. They discover how salinity and temperature of water affect its movement.

Learners experiment to discover that salt water is denser than fresh water by creating color coded solutions. They examine how heavy rainstorms and high tides develop layers of different degrees of density.

Students assess the ocean's microstructure by analyzing graphs created during tne Ronald H.Brown research cruise. they discuss at what depths various sea animals live and write paragraphs on data analysis from the graphs.

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