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
Students 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
Learners explore chemical reactions. In this chemical reaction lesson, students conduct an experiment observing chemical reactions.
Curated OER
Gel Electrophoresis
Learners 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 plan students view a demonstration and answer questions.
Curated OER
The Floating Golf Ball
Fourth graders discuss density. In 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 instructional activity, students define these two terms and determine how to find relative viscosity and the volume of an irregular shaped solid. This instructional activity has 13 short answer...
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
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
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. For 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....
Curated OER
Creating the Ideal Cargo Boat
Learners 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
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
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.
