Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...

Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

Students analyze density. In this density lesson, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

You might not be able to learn through osmosis, but you sure can observe it! Scholars observe and measure osmosis using chicken eggs. They control for multiple variables to determine which variables have an impact and how the impact...

Learners conduct a science experiment to determine whether a variety of objects will sink or float. They discuss the concept of density, and then make predictions about whether the objects will sink or float. They then conduct the...

Combine science and literature with this activity on buoyancy. Read There's an Ant in Anthony by Bernard Most to examine words containing the letters a, n, and t. Then introduce your class to the word "buoyant." Demonstrate how an...

Students explore water properties by conducting a class experiment. In this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of salt...

What's the future of biotechnology? Explore a hot topic in the fourth and final unit in a series of Biotechnology lessons. Learners develop an understanding of the many issues in bioethics, then create an argument for or against the role...

Students experiment floating a variety of objects in various liquids. They discover how density affects the ability of an object to float and apply the concept of density to solve problems.

Students observe teacher demonstrations that illustrate density. In this density lesson, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but floats in salt...

Students create and test a hypothesis about cell division. After observation of Frog Egg cell division, students write obervations and refine process and hypothesis. The use of scientific method, group work and inquiry are fostered by...

Believe it or not, biodiversity exists even in areas of disturbed habitat. An interactive activity challenges learners to look for species with a magnifying lens in an image of a city habitat. Pop-up images and descriptions explain how...

"Float like a butterfly, and sting like a bee" with a resource about the greatest boxer of our generation. A short biographical reading passage introduces young readers to Muhammad Ali, and includes information about his early life...

Young scholars perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then...

Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...

Little chemists observe the effects of acid on calcium carbonate as an example of chemical change. As a demonstration you will place a raw egg in vinegar overnight, and as a lab activity, learners drip vinegar onto a piece of chalk....

Four lessons introduce elementary ecologists to salt marsh and sandy beach habitats. In the first lesson plan, they place shells and other materials in vinegar to determine if they contain calcium carbonate. In the second lesson plan,...

Students examine how salt water is more dense than fresh water through experimentation with eggs.

Students explore the external anatomy of a fish. In this anatomy and adaptations lesson, students look at an image of a trout and identify its various external features including fins, eyes, spots, parr marks and lateral line. Students...

Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in 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.

Pupils investigate how the density of water changes the buoyancy of water. Students create a hypothesis about what will happen when placing the egg into the water.Pupils can research online different bodies of water (The Red Sea, The...
