What a bright idea! Young scientists conduct an experiment on flowers to finish the last of a six-lesson unit on Cells. Putting the stems into dye-injected water and leaving it overnight results in flowers that glow. This is to simulate...

Don't let your eyes play tricks on you ... use scale to keep your eyes in check! Young scholars observe images without scale and try to identify the structure. Then, they look at the same image with a scale bar and assess whether their...

Where does the pop in pop rocks come from? An engaging activity asks scholars to measure the amount of carbon dioxide in a package of Pop Rocks candy. Learners dissolve the candy in water and use the solubility of CO2 to determine its mass.

Develop a model of a wastewater treatment center. The last activity of the unit has pupils mix a lake water sample into a tank of water containing fertilizers. Over time, the algae from the lake water grows and removes the nutrient-rich...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function...

For as small as they are, there sure is a lot of information for young scientists to learn about bacteria. Help simplify the subject with this instructional presentation that explores the structure, nutrition, and reproduction of...

Water covers more than 70 percent of Earth's surface. Scholars learn about both freshwater and saltwater biomes in a simple presentation. They compare and contrast the differences in oxygen levels, food sources, and sunlight to better...

Students discuss what comes to mind when they hear the term cell and discuss what a cell is in biological terms. They look at pictures of cells and color a picture of a cell diagram, writing the job of each part as they go. After the...

Learners observe organisms found in pond water with a microscope. In groups, they discuss how single-celled organisms satisfy their needs for food, water and air. They compare and contrast the needs of macroscopic and microscopic...

Students examine a microscope and learn its parts.  In this microscope lesson students study the different parts of the microscope and see the differences in the adjustments then make their own wet slide. 

Students analyze a microscope and study what they do.  For this investigative lesson students study how microscopes were first invented, and how ray diagrams are used in conjunction. 

Students understand that microorganisms are too small to see but there are other indications they exist. In this microorganisms lesson, students recognize that some microorganism are helpful and some are not. Students use a microscope to...

Students design the test they use to examine, how the paramecium move, feed, and react to different types of stimuli such as a drop of vinegar. They conduct a lab experiment using a microscope.

Students conduct an experiment. In this temperate forest lesson, students discuss what kind of animal life can be found in the forest. They read The Magic School Bus Meets the Rot Squad: A Book About Decomposition and complete an...

Students explore different activities in biology, physics and chemistry. In this science lesson, students examine chromosomes using a microscope and explain their significance in sustaining life on Earth. They investigate alkanes and...

Students explore the process of evolution. They examine examples of how homeotic genes may work and obtain gametes. Using a microscope, students observe the fertilization of sea urchins. They video tape the process and write a...

Students examine a microscope and learn its functions.  In this microscope lesson students prepare a wet mount slide and complete calculations. 

Students view the video "The Invisible World" and discuss different types of microscopes and what can be seen with each type. They work in pairs to view several objects with a microscope.

Students explore scientific observations by examining the parts of a microscope. In this optics lesson plan, students discuss the importance of a focal point and focal distance when utilizing an optical device such as a microscope....

Students identify protists under a microscope, and using a stopwatch calculate the speed of a protist from a pond water sample. They use distance and time to identify the speed of a protist, and create a distance versus time graph to...

Students explore the parts of the microscope.  For this microscope lesson students are given a quiz on the parts of a microscope.

Students make simple plankton nets and use them to collect and identify common forms of plankton. They identify and interpret plankton, as seen under a microscope, whether there was more zooplankton or phytoplankton. Finally, students...

Students work as a team to use the ProScope Digital USB Microscope and a computer to collect microscopic images from a variety of organisms. When they compare these specimens, they are able to determine how they are alike and different...
