Young scholars relate heart rate and development to environmental conditions through experiment. In cooperative groups, students record the heart rate in developing zebra fish. Groups create a standard curve to predict the temperature...

Students (females) are introduced to the cell. They discuss what a cell is, and students define what a cell is. Students comprehend that all living things are made up of cells. They comprehend that life is defined as something that...

Students create and observe coacervates. In this origin of life instructional activity, students create coacervates by mixing carbohydrate and protein solutions. They observe the life-like qualities of the structures and discuss the...

Students create a sustainable, self-contained ecosystem in a ten-gallon aquarium.

For this science worksheet, high schoolers use the diatoms present in water in order to test water quality and perform data collection and interpretation.

Students investigate osmosis using egg cells with the shells removed. In this osmosis lesson plan, students remove the shell of an egg by letting it soak in vinegar for two days. They take measurements and observe the cell. They soak the...

Students observe, compare and describe cell organelles in terms of their function, structure and operation. They enter and edit information in a database, build and sort a student-designed database and find records in a database.

Learners explain the concepts of what DNA is and where it is located in a cell, identify the two types of molecules that make up the rungs of a DNA molecule and identify the two types of Purine and Pyrimidine molecules

Students explore a specific method of identifying fungi, using a written key and an illustrated key. Powdery mildew fungi can be identified to genus by the morphology (appearance) of the sexual stage (cleistothecia).

Fifth graders evaluate the physical properties of 5 powders. Each powder is subject to different conditions. They describe each observation as with a chemical change or a physical change.

Students collect samples of pond water, dried grass, and soil in a jar. They predict the order of ecological succession in their pond water cultures. They compare their expected results with their observed results.

Students perform a transection of a redworm. They discuss spinal cord injuries in humans. Students compare the ability of the redworm to regenerate the ventral nerve cord with the inability of humans to repair damage to the dorsal nerve...

Students explore different aspects of stem cells.  In this human biology lesson, students complete numerous activities including reading an article and discussing it, watching a video on stem cells reproducing over time, and...

Young scholars explore biology by identifying a diagram. In this cell anatomy lesson, students read a story about archeology and conduct a fictitious archeology dig in class in which they search for animal cells. Young scholars define a...

Students identify what factors effect global warming and how the greenhouse effect occurs.  In this environmental lesson students view videos then complete an experiment using a terrarium to observe greenhouse gas.

Seventh graders describe the processes involved in mitosis and meiosis. In this life science activity, 7th graders create chromosome models using strings and beads. They play a jeopardy team game at the end of the unit to review concepts...

Fourth graders observe brine shrimp over several days. They create drawings showing the growth and development of the shrimp. They research web sites to find out where brine shrimp fit on the food chain and what makes the shrimp unique.

Learners witness various stages of mitosis through preparing onion root tip slides. With teacher guidance, they learn a great deal through the hands-on process of preparing the slides themselves.

Students investigate the difference between plant and animal cells. They observe a variety o plant and animals cells by looking at a piece of cork, an onion, elodea, prepared slides of paramecium, human bone, frog blood, and human...

Tenth graders are introduced to the cell and some of its parts. Through the use of video, 10th graders see animal and plants cells and their parts. They learn terms used to explain the cell.

In this human cells worksheet, 7th graders complete a science experiment using human cheek cells. Students sketch the cells at high and lower power and label the cell nucleus, cytoplasm, and cell membrane.

Students study cellular structures and functions.  In this cell function lesson students participate in a class discussion then make a drawing of the cell they are discussing. 

Students practice calculating density and examine examples of the physical characteristics of soil. They solve a "crime" based on the evidence and laboratory investigations.

Students compare water quality of different sources. They test water samples for odor, phosphates, pH, bacteria, and dissolved solids. they fill out a data table and answer questions about their findings.
