Sixth graders create a KWL chart about microorganisms. In this biology lesson, 6th graders create and label a diagram on a microbial mat. They investigate the processes involved in the carbon, oxygen and sulfur cycles.

Students define reflection and refraction. In this Physics lesson, students compare a variety of items to find properties of reflection or refraction. Students record their findings.

In this soil worksheet, students complete 2 pages about the importance of soil in plant growth. Kids read about red worms and answer 2 questions about composting. Students fill out a chart with their observations of plants planted in...

Students create a three dimensional model of a cell. In this cellular structure lesson, students use gelatin, plastic bags, plastic containers, and fruit to construct a model of a cell. They compare the cells structures and stack them to...

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...

Junior geologists work through three mini-lessons that familiarize them with the formation and location of fossil fuels. Part one involves reading about petroleum and where it comes from via a thorough set of handouts. A lab activity...

Hands on science is the way to go! Learners conduct a lab experiment to help them explain how plants make food through photosynthesis. They test for the presence of starch in leaves using iodine solution and identify the basic things...

Students observe the effects of eutrophication and determine why it is harmful to aquatic ecosystems. They create mason jar ecosystems to observe the growth of algae in pond water. In addition, they observe the effect of introducing...

Plankton isn't just a tiny cartoon character, it's also a very important food source for animals around the world. Budding scientists discuss the types and functions of plankton, including where they are found, how they are caught, and...

Students read background information about Monterey Bay, California, and conduct related experiments. In this ocean in motion lesson, students read information about the location, wildlife, and characteristics of Monterey Bay. They...

Seventh graders identify the names and features of macroinvertebrates found in Turtle River.  In this ecology lesson students use digital microscopes and take pictures of invertebrates. 

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

Jiminy cricket! If you find yourself plagued by fear of dissection, these locust respiratory system dissection directions will walk you through everything you need to know. Teens inspect a living locust to begin with, then jump over to...

Sixth graders observe, describe, and classify microorganisms found in water sources. In small groups, they make their own slide, observe the Protozoa under a microscope, and record and classify the microorganisms.

Students explore biology by participating in a fun science experiment. In this DNA instructional activity, students discuss what DNA is and where it comes from. Students utilize two bananas, a blender and a microscope to view the DNA of...

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 complete activities to study decomposition. In this decomposition instructional activity, students work in pairs to observe a decay buffet experiment. Students keep compost bag journals. Students define and discuss the process...

Students determine if changes in pH affect the growth and survival rates of aquatic plants. They evaluate the optimal pH levels for the growth of aquatic plants.

High schoolers determine the optimal temperature at which brine shrimp eggs hatch and develop. They evaluate the changes, if any, which occur in a brine shrimp culture at various temperatures.

Students determine if different temperatures effect the growth and survival rates of aquatic plants and evaluate the optimal temperature for the growth of aquatic plants.

Students determine if brine shrimp eggs hatch and develop more readily in an environment which has an acid or a basic pH. They evaluate the pH level which is optimal for the hatching and development of brine shrimp.

By setting up an aquarium in the classroom, learners are able to describe some macroscopic and microscopic organisms that are found inside. This well-designed, and educationally rich lesson requires pupils to use microscopes to view...

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

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...
