The Intertidal Zone: Tides and How Creatures Survive
Students study the properties of ocean water and tides and learn about animals that live in intertidal zones. In this intertidal zone lesson, students participate in classroom stations to learn about fresh water and salt water, cold...
Curated OER
Laboratory - Density of a Material
Students conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.
Curated OER
MANAGING THE SCHOOL FOREST
Students study how to plant a seedling, how to mulch the trees into the nursery bed, transplant seedlings to another site or school, and determine why we need to water and mulch trees.
Curated OER
Float or Sink?
Learners examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...
Curated OER
Keep Cool
Students design an experiment to determine which type of container would be best to use to keep drinks cool on a hot day. Students test paper cups, styrofoam cups, and metal cans by filling them with ice water and they use a thermometer...
Curated OER
Snail Observation Exercise
Learners are given a pond snail in a clear glass and asked to make observations on the snail's form and behavior. One of the key ideas is that seemly common subjects (like snails) often have surprising or interesting properties.
Curated OER
Waves: Understanding the Motion of Waves
Students demonstrate the motion of waves. In this wave lesson, students demonstrate the various attributes to waves and the properties through a variety of hands-on activities.
Curated OER
Physical Difference and Classification
Students use a microscope and observation skills to compare and contrast several physical properties and develop a classification system.
Curated OER
Color Dots 3
Students make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.
Curated OER
Float My Boat
Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..
Curated OER
Sediment Tubes
Students observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.
Curated OER
Milk: A Practical Application
Students examine the impact of the physical and chemical properties of milk and its use as an important food.
Curated OER
Critter? Growth
Students identify and use the elements of the scientific inquiry to solve problems. They explain concepts about the structure and properties of matter. Pupils write an explanation of polymers and how the characteristic of polymers...
Curated OER
What Makes the Wind Blow?
Student study the properties of wind. They make a miniature hot-air balloon and compose diamond-shaped poems about the wind. They explain that as the sun warms air around the earth, the air rises. Colder air then moves in to fill the...
Curated OER
What Makes Good Long Undies?
Students examine a variety of different types of fabrics and discuss what characteristics would make a good pair of long underwear for a journey to Antarctica. They investigate the properties of various fabrics and determine how they...
Curated OER
Goofy Putty
Students examine mixtures and solution properties by making a borax polymer. In this chemical reactions lesson, students make a putty out of borax solution mixed to create a polymer.
