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
MANAGING THE SCHOOL FOREST
Pupils 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
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
Float or Sink?
Young scholars 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...
Curated OER
Snail Observation Exercise
Young scholars 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
Measurement: Length, volume, and temperature
Students determine the temperature of the water in a cup, measure the length of a piece of cardboard, and measure out an appropriate volume of water. This task assesses student's abilities to perform measurement and reporting skills.
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
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.
Curated OER
What Boat Designs Float the Best?
Fifth graders investigate buoyancy by conducting a science experiment. In this water properties instructional activity, 5th graders predict which of their different paper boat designs will float for the longest period. Students conduct...
Curated OER
Milk: A Practical Application
Pupils examine the impact of the physical and chemical properties of milk and its use as an important food.
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
Phases of Matter
Students describe the motion of solids, liquids and gases. In this chemistry lesson, students describe how temperature affect motion of the particles. They determine the physical properties of each phase.
Curated OER
Cool Collectibles and Super Sorts
Second graders investigate properties of rocks and create a classroom rock collection.
Curated OER
Construct with Solids
Students discover which properties of solids lend themselves to building a tower through hands on trial and error and observation of others as they are building. They write down the steps it took them to build the tower and label an...
Curated OER
Efficiency Means Getting More for Less
Students measure water and make predictions about efficiency.
Curated OER
Solubility and Chemical Changes in Groundwater
Students test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH of the...
Curated OER
Frozen Solids
Students investigate various properties of ice including melting points and the effect of pressure on ice. They demonstrate how increased pressure lowers the melting point of ice and perform a simple experiment proving that water is more...
