How does electricity work? Budding scientists explore the concepts of electrical currents and open and closed circuits with class discussion and a hands-on activity using a battery to turn on a light bulb. Learners also make predictions...

Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

Students complete a project where they label the parts of a coral polyp and discuss the differences between plants and animals. Students use marshmallows, sprinkles, toothpicks, and more to label their coral polyp.

Students define aerobic and anaerobic respiration. They compare and contrast the processes of aerobic and anaerobic respiration. Students identify organisms that use the processes of aerobic and anaerobic to synthesize energy from food.

Students study silicon and where it comes from.  In this solar mining lesson plan students complete an Internet search of mining and a lab activity. 

Students study chloroplasts, their structure and evolution.  For this photosynthesis lesson students experiment with polarized light and the production of chlorophyll.

Students define the key terms that are the structure and function of DNA. In this genetics lesson students complete a lab activity in which they construct a model DNA structure.

Pupils explain the roles of mRNA, tRNA and ribosomes. They explain how mutations can occur in an individual. Students simulate parts of a cell to access about the process of protein synthesis.

In this homeostasis and plasma membrane worksheet, 9th graders identify and solve 11 different vocabulary terms and definitions. They review the definitions of the words listed and then use the clues to complete the puzzle shown....

Seventh graders explore science topics using a SMART board. In this respiration lesson, 7th graders see how and why cells use cellular respiration. They see a cellular respiration recipe on the SMART board and watch as the cells produce...

In this photosynthesis instructional activity, students are given a diagram of photosynthesis and words that correlate with the process. They use the words to fill in the blanks about the process and the structures involved in...

Students gain an understanding of how systems and organs in the human body work. They create their own fictional account of a trip through the human body, and describe one response the body makes to stimuli.

Open this lesson plan by reading together about primary and secondary batteries (such as nickel-cadmium cells), problems they can cause in the environment, and how humans can minimize the damage. Afterward, little ones examine a...

Pupils identify photosynthesis as the mechanism by which plants convert sunlight energy into a usable energy source for plant processes. They identify photosynthesis as the mechanism by which plants create a molecule that can be used to...

Students discuss the process of photosynthesis in plants and that oxygen is produced as a by product. They observe underwater Elodea plants "breathing" in a hands-on activity. After setting up the experiment, they observe the plant for...

In this biology worksheet, 9th graders explain how producers make their own food. Then they describe the food chain and what the end products are of respiration. Students also describe how muscles continue to get energy during high...

Students study three structures of a plant as well as their locations and functions.  In this botany lesson plan students complete several activities on plant organs and their functions.

In this body systems worksheet, learners read information about the processes involved in the respiratory and urinary systems. Students then answer 1 short answer and 2 multiple choice questions.

Eighth graders define the terms: magnetism, poles, compass, magnetic field, lines of force, electromagnet. They name two properties shared by all magnets and describe how one magnet will affect another.

Students prepare single strands of muscle cell. They microscopically examine muscle cells and identify bands of darker and lighter proteins. They predict, observe, describe and quantify the effects of ions and ATP.

Students experiment to produce a visual convection current in the classroom and compare it to the images taken of convection cells in the Sun. They analyze the source of the Sun's energy and this type of energy transport.

Young scholars identify photosynthesis as a process through which organisms make their own food. They practice the process for writing the formula for the photosynthesis equation. Students describe how the processes of photosynthesis...

Students conduct various experiments on glucose. In this biology lesson, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.

In this photosynthesis worksheet, students learn how plants use the sun to convert energy into food. They then answer 10 questions using the information they just read. The answers are on the last page.
