Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.

In this Cartesian diver lab, learners explain using text and diagrams how the Cartesian diver works. Students evaluate ways in making their lab design better. Learners make predictions of how changing the variable would change the...

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...

Students participate in a variety of experiments designed to illustrate types of heat transfer including conduction, convection and radiation. They complete worksheets as an assessment of the experiments.

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...

For this hot and cold water worksheet, students use hot and cold water to experiment and see what happens when the two mix together. Students also answer 7 questions.

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

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 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.

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.

Sixth graders experiment with the froth flotation process to extract metallic ore by using basic chemicals and equipment in the science classroom.

Students study the structure of the lungs. In this lung structure lesson plan, students use lung models to study the structure of lungs and experiment to measure the amount of air in the lungs.

Students examine and identify the observable properties of coal. After a lecture/demo, students perform a simple experiment. They observe samples of coal and record data in an organized manner.

Use STEM activities within the class to provide connections to concepts. The resource includes activities that range from working with buoyancy to building rockets and launching them. Other activities involve the engineering design...

Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.

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 use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.

In this layer of the earth worksheet, students label and color each layer of the earth. Then students are asked to describe each layer below.

In this seasons worksheet, students cut out the picture cards at the bottom of the page, sort the pictures and paste them with the matching season.

In this worksheet on the life cycle of the butterfly, students look at 4 pictures representing the life cycle stages, and choose words from a word box that match each picture. Students then number the pictures in the correct order of...
