Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...

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...

Students identify the parts of the egg and observe the composition of the egg parts.

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...

Students investigate the effects of substances on the viscosity of egg yolks. In this viscosity lesson plan, students separate egg yolks from their albumen and then add different masses of albumen back to each egg yolk. They measure the...

Learners know the following parts of an egg as the yolk, white, shell, membrane, chalaza, and air sac. They also sequence the growth of the chick in the egg. An egg is broken and students touch, smell and see it. They locate the six...

Students recognize the need for gentle care of eggs. In this chicken hatching lesson, students observe the process of incubating eggs for hatching. Students find the materials needed to properly care for the chicks. Students complete a...

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

Students conduct an experiment comparing human cells to chicken cells. In this cells lesson plan, students conduct an experiment to see how nutrition moves through cells and how to better take care of their bodies.

Students 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 test...

Students explore package engineering and investigate design.  In this shipping lesson students are given a flower and are to come up with a packaging that will allow the flower to get to its destination as fresh as possible. 

Second graders identify ways that both insects and humans protect themselves from physical and biological hazards in their environment. They rear moths from egg to adult and consider the importance of trusting their own instincts.

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 study the ocean and its characteristics.  In this oceans instructional activity students complete a lab activity and are able to predict temperature of certain depths. 

Young scholars conduct an experiment where they will change a liquid dairy product into a solid. They review the definitions of liquids and solids. Students are given an example of each. They are divided into groups of four, each group...

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...

Pupils manage and retrieve numbers and letters that are logically sorted. In this logical information lesson, students do the flood game from the PBS website. Pupils answer questions about library books.

Students investigate major pigments which occur naturally in fruits and vegetables, and to use them to dye a number of items. They study the effects of pH on anthocyanin on pigments.

Students answer the question, "How could citrus fruits be toxic to fruit flies when fruit flies live on fruit?" They conduct an investigation using four different citrus oils and fruit flies and analyze data collected.

Young scholars collect their own flies and construct crosses, then compare them to the data from activity two.
