Learners design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.

Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.

Students explore water, molecules, and surface tension. For this floatation lesson, students discover why some objects are able to float on water as they follow the procedures included in this activity.

Students use streaming videos, web sites, and hands on activities students to explore matter. They focus on how temperature affects matter and what the particles look like in the states of matter.

For this density laboratory worksheet, learners complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.

For this biology worksheet, students use the website given to become familiar with the equipment of a lab. The activity involves a link to a virtual laboratory. Then they determine an objects mass and volume by placing it in a graduate...

Students explore letter Ww. In this letter recognition lesson, students participate in country, state, food, literature, physical education, colors, careers, music, and game activities that are linked to the main lesson page. Students...

Learners study the ocean and its characteristics.  In this oceans lesson students complete a lab activity and are able to predict temperature of certain depths. 

Students complete a variety of activities using pumpkins. They visit various stations with various pumpkin activities.

First graders listen to the book "Mr. Betts and Mr. Potts" and examine the career of being a veterinarian. They categorize animals based on whether they could be house pets or not, develop a class pet graph, and list the various...

Students investigate the states of matter. In this physics lesson, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.

Students complete several cross-curricular activities to learn the letter Ff. In this letter recognition lesson, students complete activities that include geography, music, physical education, science, seasonal, space science, and online...

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.

First graders write about vehicles that float.

Learners examine the relationship between density and buoyancy.  In this physics lesson students use Archimedes' Principle to complete calculations on buoyancy and a lab activity.

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 use hands on scientific observation to determine characteristics of wood. They work directly with the materials and record their observations. Students test if wood absorbs water, if wood floats or sinks, and if all wood...

Young scholars explore the impact of invention. In this invention lesson, students examine how inventions are on going and affect all aspects of life in both good and bad ways. Young scholars will research the history of invention,...

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...

Eighth graders determine the density using mass and volume. In this science lesson plan, 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...

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.

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...

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.

Students discover how seeds travel from their parent plants in search of water, sunlight, and nutrients, and conduct experiments in which they note characteristics that encourage seed dispersal by means of wind, water, animal carriers,...
