Students investigate how plants grow by analyzing pumpkins. In this agricultural lesson, students read The Biggest Pumpkin Ever by Steven Kroll, and draw pictures of a pumpkin in each of its growing stages. Students measure and dissect...

Students explore the concept of density by trying to make a penny and other materials float.

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

Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

Study how plants grow with your English language learners with a cross-curricular lesson plan revolving around pumpkins. These activities provide opportunities to practice new scientific vocabulary while practicing skills such as...

Students examine whether objects will sink or float.  In this buoyancy lesson students bring in objects and experiment to see if they sink or float.

Students build a miniature replica of the Mayflower. They make the boat float in a cup of water while studying the concept of gift giving on Feast Day.

Seventh graders discover the definition of density through a demonstration using ethanol and ice cubes and a class discussion using a SMART Board to illustrate formulas and calculations. Students finish the lesson by practicing...

Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

Young scholars investigate buoyancy by participating in a lab experiment. In this density instructional activity, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Young scholars analyze which...

Middle schoolers participate in an experiment to determine if a toy boat will sink or float. They make the boats out of different materials and determine its carrying capacity by adding pennies. They graph their findings on a classroom...

Students understand the properties of Bamboo and what it can be used for. In this bamboo lesson, students with bamboo and compare and contrast to wood. Students share their findings.

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

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...

Learners 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,...

Students explore the Big Bang Theory and the Theory of Plate Tectonics. In this history of life lesson, students explain two ways the Theory of Plate Tectonics and the Big Bang are of direct benefits to humans.

Students examine geographical change. In this mountain barriers lesson, students conduct an experiment to discover how mountains affect surrounding land.  Students draw conclusions on how change in land affects plant and animal life.

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..

Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.

Students study the properties of the physical and natural world. In this properties of the physical and natural world lesson, preschool students work at discovery tables to see how simple machines work, what happens when items are put...

Students construct their own submarine following a certain procedure. In this physics instructional activity, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some...

Students investigate surface tension in water. In this water molecules and surface tension lesson, students observe 3 demonstrations to show how water molecules are attracted to one another, how soap reduces the surface tension in water...

Students experiment with water density, temperature and salinity. In this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.
