The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

Students explore the world of the very small using a Flash plug-in Virtual Electron Microscope. They complete and discuss an activity in which unknown samples are placed under the computer simulated microscope to determine where the...

In China, hibiscus is known as the shoe flower because it is used to polish shoes, while in Hawaii, it is honored as the state flower. Young scientists learn about the structure and function of flowers. They dissect hibiscus...

Here is a lab activity adequate for use with any full instructional activity on environmental factors that shape animal adaptations or marine animal characteristics. Pupils will discuss the role plankton plays in the environment and...

Students collect, study and observe the pollution in our air. They list three kinds of pollution that they think is in our air. Students comprehend that the atmosphere is almost completely made up of invisible gaseous substances. They...

Observe onion root cells undergoing mitosis underneath a light microscope and determine the phase of mitosis the cells are in. High schoolers draw a sketch of the mitotic cells, explore why cells undergo mitosis and learn how...

Totally gross out your class with the eighth lesson in this series on food science. Explore the microscopic world of bacteria by taking swabs of different classroom objects and growing colonies in petri dishes. An engaging activity that...

In this computer technology lesson students investigate silicon microchips.  Students explore microchip technology using a microscope.  Lesson contains hands on investigations.

Students identify under a microscope several different genera of protists. They discuss the three different categories of protists. Students discuss characteristics of the protists that they have already been taught. They view and...

Learners collect samples of common dust from their homes and school for examination under a microscope. They identify the components of their samples using the provided "Atlas of Indoor Dust Particles." Pupils take samples form a variety...

Plankton are so abundant in the ocean they outweigh all of the animals in the sea. In this three day activity, groups discuss and become familiar with plankton, capture females, and look for egg production on day three. 

Thirty percent of the world's oxygen is produced by rainforests found throughout the world. Seventh grade learners explore the processes of photosynthesis and respiration through 10 days of labs, manipulatives, and discussions. They...

Brown rice contains vitamins B and E, while white rice lasts longer in storage. The availability of rice around the world makes it a great candidate for genetic engineering. Scholars apply their knowledge of genetic engineering to solve...

Students examine organs from dogs and cats to study reproduction, embryology, and the identification of cancer. They record their observations at both the gross and microscopic levels. They present their information to the class.

Students collect and microscopically examine seeds from the school yard and neighborhood. In small groups, they draw and discuss the shapes of the seeds to determine each plant's method of dispersal. they also test two types of seeds...

How can you tell if a microorganism is helpful or detrimental to an ecosystem? Learners inspect slides or pictures of microorganisms and record their observations to...

Students explore that volcanoes produce rocks.

Students investigate with sea urchins. In this ocean habitat lesson, students observe sea urchins and other ocean grazers. Students work with lab equipment to examine the anatomy of these creatures.

Students observe osmosis, a cellular process that normally can't be observed without a microscope, and use scientific method to observe osmosis in a chicken egg.

Students recognize slides of different fungi. They work in lab groups. Students view slides under the microscope, then draw and label the parts, magnification, and the organism. Students discuss similarities between some fungi and...

Students describe the cell cycle. They make a connection between DNA replication and cell division. Students describe the parts of the cell that participate in cell division and the steps of cell division.

Young scholars participate in classroom experiment to gain better understanding of type of environment brine shrimp can best survive. Students then explore effects of common saltwater pollutants on survival of animals in sea.

Seventh graders define the term microbe. They identify the five main groups of microbes. Students give examples of ways in which microbes have impacted or currently impact human life. They create a hypotheses for where they expect to...

Students take measurements of the distance between the objective and the slide when in focus with each objective. They determine the diameter of the field of view at each power in order to determine the size of the cells being observed.
