How Does the USS Alabama Float?
Students investigate buoyancy. In this buoyancy lesson, students apply the Archimedes Principle of Buoyancy to the experiment conducted in class to determine how battleships float.
Curated OER
The Weight of Water
Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.
Curated OER
Soda Bottle Boat
Students explore chemical reactions. In this chemical reaction lesson, students conduct an experiment observing chemical reactions.
Curated OER
Sink It
Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.
Curated OER
Seashore Explorers
There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...
Curated OER
Floating Paper Clip
In this density worksheet, students conduct a science experiment. Following the given directions, students must work to get paper clips to float.
Curated OER
It's OK to Reach Your Boiling Point!
Middle schoolers view a video which introduces them to density and the states of matter. They experiment, collect data, and graph the boiling/freezing points of several edible items...and then make brownies!
Curated OER
Cartesian Diver Lab
In this Cartesian diver lab, students explain using text and diagrams how the Cartesian diver works. Students evaluate ways in making their lab design better. Students make predictions of how changing the variable would change the...
Curated OER
Density
Students, in groups, design a procedure to calculate the mass of gas molecules in the classroom by measuring the volume of the classroom and researching the density of air. They apply changes in air density with altitude and effects on a...
Curated OER
Viscosity and Density
In this viscosity and density pre-lab worksheet, students define these two terms and determine how to find relative viscosity and the volume of an irregular shaped solid. This worksheet has 13 short answer questions.
Curated OER
Science Lesson #2
Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...
Curated OER
Student Experiment Flies On NASA Space Shuttle!
Students design and construct an experiment that will be launched into space aboard a NASA research shuttle. How better to gain and appreciation for (and, hopefully, a love of) scientific investigation than to do real science and be...
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
Electrolysis
Young scholars conduct a series of experiments on water electrolysis. For this chemistry lesson, students explain what happens to the molecules during the process. They cite real world applications of electrolysis.
Curated OER
Leaf Stomata as Bioindicators of Environmental Change
Learners perform an experiment to determine the stomaltal index on the upper and lower epidermis of two species of leaves. Stomatal densities change in response to changing atmospheric levels of carbon dioxide and to annual rainfall.
Curated OER
The Great Heat Escape
Students observe a demonstration on the role of thermal conductivity in heat transfer. In this thermal conductivity lesson, students design and conduct an experiment to compare the thermal conductivity of four substances....
Curated OER
Leaf Stomata as Bioindicators of Environmental Change
Students, in this experiment, collect leaves from two species of trees and the stomatal index on the upper and lower epidermis of each leaf be determined.
Curated OER
Bending Light
Sixth graders read Hatchet by Gary Paulsen, discuss refraction, identify example of it from novel, and perform classroom experiments demonstrating refraction and reflection.
Curated OER
Creating the Ideal Cargo Boat
Students build boats out of clay to test the buoyancy of the boat in water. Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.
Curated OER
Gel Electrophoresis
Students conduct a variety of experiments to explore gel electrophoresis. In this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.
Curated OER
Estuarine Currents
Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.
Curated OER
The Motions of the Oceans
Students examine the topics of ocean waves, currents, and tides. They locate and label ocean currents on a world map, conduct experiments, analyze key vocabulary, view demonstrations and record the data, and complete handouts.
Curated OER
Water Layering and Circulation
Young scholars examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.
Curated OER
The Solar System
Third graders investigate Newton's law of Motion. In this chemical reaction lesson, 3rd graders participate in an experiment with rockets to study Newton's law. Students observe the effects of a chemical reaction made by combining...
