Rotational Dynamics
In this motion worksheet, students calculate the initial angular acceleration, and the angular speed before and after impact for different objects. This worksheet has 3 problems to solve.
Curated OER
Science: Exploration Tubs
First graders develop skills of scientific inquiry. They determine which objects float and which sink.
Curated OER
Water Displacement
Students formulate a hypothesis using critical thinking skills. They use an orange to examine the displacement of water as the orange sinks or floats.
Curated OER
The Buoyancy Factor
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...
Curated OER
The Weight of Water
Students participate in an experiment about the weight of water. They work together to discover that seawater is more dense than fresh water. They also determine which objects float and sink.
Curated OER
Activity #16 Dancing Spagehetti
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...
Curated OER
Wonderful Water
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...
Curated OER
Buoyant Force
Students illustrate Archimedes' Principle of Buoyant Force. In this graphing activity, students will observe that the buoyant force on an object is equal to the weight of the fluid it displaces. Students will then create a graph showing...
Curated OER
i-Density Crisis
Eighth graders determine the density using mass and volume. In this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...
Curated OER
Lesson-Mass and Weight
Student identify the three stationary positions, on the Earth, on the Moon, and in a house floating atop the cloud layers of Jupiter. They also identify the three orbiting positions, orbiting the Earth, orbiting the Moon, and orbiting...
Curated OER
Floaters and Sinkers
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...
Curated OER
Introduction to Density
Seventh graders define density in their own words. In this physics lesson, 7th graders solve density problems using its mathematical formula. They explain why some objects flow and some sink.
Curated OER
Galapagos Rift Expedition Come On Down!
Students research the development and implementation of a research vessel/vehicle used for deep ocean exploration. In this oceanography lesson, students calculate the density of objects by determining the mass and volume.
Curated OER
Marine Debris
Students will perform experiments to examine if debris will float, or blow in the wind. They discuss the effects of these characteristics on marine debris.
Curated OER
Get Down With Density
Students define density and observe that things that are less dense than water will float. Students find the density of copper, iron and aluminum
Curated OER
How Wet Can You Get?
Students visit a swimming pool and brainstorm different water sports and what benefits swimming has over other types of exercise. They then discuss buoyancy and water pressure and when how objects sink or float before playing a game of...
Curated OER
Christo/Transformations--from Discovering Great Artists
learners challenge their imaginations like the artist Christo by transforming an everyday object into something new. Students use everyday objects in order to create something new. Learners use materials such as objects found in nature...
Curated OER
Feeding Frenzy
Students are divided into two teams in which its members are to gather as many objects in the pool as possible gaining points for different objects.
Curated OER
Magnet Experiment
For this magnet experiment worksheet, students complete a magnet experiment by following the 7 steps. Students fill in the table for the 10 objects they test.
Curated OER
Investigating Density: Heavy Ice
Students end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.
Curated OER
How Dense Are You?
Young scholars examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.
American Chemical Society
Defining Density
Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...
