Playing with balloons, water, oil, and bottles help put this lesson over the top! Participants use air-filled balloons in water tanks to experience gas compression. They also use oil-filled bottles to experiment with buoyancy. Included...

First graders work in cooperative groups and utilize a variety of materials to test objects ability to sink or float. In this sink or float lesson plan, 1st graders discover why some object sink and others float. Students will graph...

Students conduct experiments in which they investigate which materials float and which sink. They examine what qualities the materials that float have in common. They carry out a scientific investigation, predict, and test their...

Students use simple materials to make model sailboats which must stay upright and sail straight in a testing tank.

Students explore the principles of buoyancy and Archimedes' Principle and design their own flotation device. They compare the dimensions of a model to the real object to determine scale and analyze the models to suggest improvements.

Learners inspect nutrition by conducting a science experiment in class. In this vegetable identification lesson, students examine a group of different veggies and predict whether they will sink or float in a tub of water. Learners check...

Pupils explore the density of soap. In this science lesson, students conduct an experiment to find which types of soap will float. Pupils make a hypothesis and record their observations.

Learners define the terms "mass," "volume," and "density." The relationship between these three terms is established. They observe the differences between Regular and Diet Coke. They develop an hypotheses about why a can of Regular Coke...

Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample...

Cruise ships offer many engaging opportunities for real-world math adventures. These large, floating cities use resources with numbers into the thousands place. Young mathematicians are asked to calculate numerical information...

Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...

Students explore aquariums. In this fish and ecosystems lessons, students establish a freshwater aquarium environment using materials provided. Students read about and care for the classroom fish.

Learners research and report on the ocean's problems of disappearing or diminishing species around the world. students examine ecosystems and food chains and present their findings to a mock panel of science experts.

Students investigate the density of liquids. For this geometry lesson, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.

Students study how a geologist examines a hazardous waste spill using an actual site. They use site data to map the spill, find its source and determine how fast the spill is spreading.

Students research and experiment to discover the lifting power of helium gas.

Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.

Learners choose a famous person to write a one to three page report about. They conduct research using electronic encyclopedias, biographies, and videos. When students have all presented their reports, the class has a party.
