Motion in Fluids
Students explore physical science by participating in a science activity. In this liquids lesson, students discuss how fluids can be affected by motion unlike solids. Students define other scientific vocabulary terms and conduct a motion...
Curated OER
Ocean Layers
Young scholars investigate how temperature and salinity causes ocean layering. In this ecology lesson, students observe and sketch their experimental result. They report their findings in class.
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
Investigating Space Requirement of Seed Plants
Students use scientific methods to investigate the effects of overpopulation of seed plants on growth in a limited living space. Students relate seed plant population findings to that of other organisms.
Curated OER
Density and Buoyancy Experimental Design
Learners must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."
Curated OER
Floating Pencil
Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...
Curated OER
Soda Bottle Boat
Students explore chemical reactions. In this chemical reaction lesson, students conduct an experiment observing chemical reactions.
Curated OER
Recycling of Plastics
Students separate plastics according to their densities, develop a method for separation and identify variables in an experiment and a fair test, changing only one variable at a time for a fair comparison. After testing, they develop a...
Curated OER
Activity #15 The Cartesian diver
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...
Curated OER
Characteristics of Matter
Students study matter. In this science lesson plan, students examine the relationships among gravity, weight, and mass, the metric measurement of distance and volume, and density and its application to physical properties.
Curated OER
Lip Balm Chemistry
Young scholars explore density, mixture and solutions in a reaction. In this chemistry lesson, students create their own chap-stick using ingredients they analyze for their chemical contents. They discuss measuring skills, melting points...
Curated OER
The Sun as the Driving Force of the Water Cycle
Students study the water cycle and how the sun is an important factor. In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.
American Chemical Society
Engineering a Floatation Device
Classes will definitely not be sinking after a buoyant lesson! A project-based assessment helps highlight the importance of prior knowledge as individuals design a floatation device for a cell phone. They use their knowledge of chemical...
PBS
Sink or Swim?
What's with all the numbers on plastic products? Learners complete an in-depth analysis of the physical properties of the different plastic types. They connect the properties of the plastics to uses and test their observation skills by...
Curated OER
DIY Lava Lamp
Students examine lava lamps and what causes them to work. In this density lesson students make a lava lamp and write the scientific explanation of what happens.
Curated OER
What Does It Matter?
Students define matter, the chemical properties of matter, and the physical properties of matter. They name physical and chemical properties of matter (by classifying using a Tree Map). Students determine the mass, volume, and density of...
Curated OER
Atmospheric Processes -- Convection
Students work together to discover how temperature changes can affect the density of water and air. They make predictions on what they believe is going to occur. They answer questions to complete the lesson.
Curated OER
Soap, Wood, and Water
Young scholars measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.
Curated OER
Effects of the Southern Pacific Railroad Causeway
Fifth graders describe the appearance of a substance before and after a physical change. They re-create the Southern Pacific Railroad Causeway across the Great Salt Lake. They determine for themselves how the water is exchanged...
