Aluminum Foil Boats
Learners design a boat of aluminum foil and calculate the density of the boat. Washers are added to the boat until it sinks. Students then redesign boat to hold more washers and recalculate the new density.

Why Could the Hindenburg Float?
Tenth graders experiment with floating and sinking objects and heavy and light liquids, using correct terms, like density, to explain what happens. In this Hindenburg activity, 10th graders watch a demonstration called the...
Curated OER
Day Six: Floater What Ifs
Students observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...
Curated OER
Motion in Fluids
Students explore physical science by participating in a science activity. In this liquids lesson, students discuss how fluids can be affected by motion unlike solids. Students define other scientific vocabulary terms and conduct a motion...
Curated OER
The Floating Golf Ball
Students explore density by floating golf balls. They explore having their golf balls float halfway in a container of water and discuss density and its realtionship to where the golf balls are floating. After adding food coloring, they...
Curated OER
Color Splash
Students investigate density. In this density lesson, students conduct an experiment using food coloring. Students observe the differences in mixing food coloring in water and oil.
Curated OER
Earth: The Water Planet
Students elicit data on the water cycle, ocean topography, and island formation in this six lesson unit. The ocean floor and the properties of water are examined through a variety of discussions and hands-on experiments.
Curated OER
Salt Water Wedge
Learners conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...
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
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
Diving Raisins
Students participate in a mini lab to explore density. In this density lesson students view a demonstration and answer questions.
Curated OER
The Floating Golf Ball
Fourth graders discuss density. For this floating golf ball lesson students complete a lab activity on density while working in groups.
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
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, learners 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
Float Your Boat
Students design an experiment to find density using Archimedes' Principle. In this physics lesson, students calculate density using mass and volume. They share their findings in class.
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
Condiment Diver: The World's Simplest Cartesian Diver
Students explain what density is in their own words. In this physics lesson, students perform the condiment experiment and explain why some float and some sink. They share their findings in class.
Curated OER
Leaf Stomata as Bioindicators of Environmental Change
Students 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....
