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.

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 are introduced to a basic characteristic and need of living things-the ability and need to reproduce. They investigate how birds (and people) attract mates. Students discover how to build a nest. They discuss the needs and...

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...

"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...

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...

In this life cycle of a frog instructional activity, students fill in the blanks to paragraphs about the life cycle of a frog using a word bank. Students fill in 13 blanks total.

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.

The National Park Service has produced a high-quality presentation on the halibut population of Glacier Bay, Alaska. It takes the viewpoint of the marine biologists or rather, ichthyologists, who have been studying the adaptations,...

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

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 study the basic need for animals to attract mates and reproduce young.

Students study the properties of the physical and natural world. In this properties of the physical and natural world lesson, preschool students work at discovery tables to see how simple machines work, what happens when items are put...

Seventh graders investigate the life cycle of the mosquito. In this life cycle lesson, 7th graders gain knowledge about the diseases mosquitos carry. Students breed mosquitos and investigate their eggs. Students collect and record...

In this components of the ocean worksheet, students answer 20 questions about various species in the ocean such as plankton, different types of whales, sharks, and herring. Students also answer questions about the volume of water in the...

Young scholars participate in an experiment about the weight of water. They work together to discover that seawater is more dense than fresh water. They also determine which objects float and sink.

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...

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,...

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...

Fourth graders focus on fluency by reading the book Charlotte's Web. In this reading strategies lesson plan, 4th graders partner read, do guided reading, and independent reading to increase fluency. Students use Venn Diagrams,...

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...

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...
