Students predict the number of cells after a series of cell divisions.  In this cells lesson students create a graph of their results and create a patterned drawing. 

Torque--a teachable moment? Here's a lesson on torque (or moment) and variables that include size, reinforcement, structural bracing, and material that affect torque.

Students investigate the concept of a job and how they can differ for each household. They examine a tool box filled with different tools and identify the types of jobs could be done with them. Then the teacher conducts a class discussion.

Third graders review and expand their discussion of job training and education resources. They work in small groups to find information about the types of training people need to do specific jobs and use data from interviews carried out...

Students examine how regional geology affects bridge foundations. In this physical science instructional activity, students explore how bridge types are constructed for different purposes.

High schoolers explore the debate between intelligent design and Darwinism. They research both topics by accessing primary sources. Students interview school administrators to determine what its science curriculum is and the timeline for...

Focused little scientists will flitter their arms back and forth across the room with excitement as they learn the life cycle of a butterfly and how living things grow and change over time.

Second graders investigate the skill of solving problems. They have class discussion about problem solving and identify the steps in settling conflicts. The strategies are demonstrated for application to problem situations and student...

Learners investigate the process of making a newspaper using children's literature to create context for the lesson. The readers are asked to predict the events of the story as it is read to them. Then the teacher uses guided questions...

Students build and compare models of both an energy inefficient and efficient classroom. In this energy efficiency lesson, students creatively use recycled materials to build two separate classroom models. They factor in concepts such as...

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

If you can find Tinker Toys™, then this may be a fun assignment for your physical science class. Using the construction set and a few other toys, they examine the forces involved when it they are being played with. For each, they...

Seventh graders discover the interconnectedness of plants and animals in ecosystems. In groups, they create a food web and discuss the problems when one link of the chain is broken. To end the lesson, they set up a balanced environment...

Students, in teams, use given materials and their knowledge of Newton's First Law to create a device that will remove a sticky ping pong ball from a 16-oz. cup (which represents ketchup stuck in a bottle.)

The classic "Egg Drop Activity" is described in this fine science lesson plan. Young scientists work together to design a container that will protect the eggs inside of it when dropped from a high place. Lots of good scientific...

Students, in groups, receive a box of artifacts. They record their findings and discuss what the items would have been used for. They come together at the end of the lesson to share their findings.

A blood sucking what? Grade schoolers identify the characteristics of blood sucking parasites. They organize their information, identify their arguments, and present them to the class in persuasive arguments. They participate in a debate...

A branching key is a great way to classify different types of animals and plants! Fifth graders answer several yes/no answers about three different plants. They then create their own key to differentiate between an iris, a rose, and a...

Students apply knowledge of soil, environmental impacts, economics, multiple human demands, and use given data for a proposed scenario in making land use decisions. They debate land use issues and/or scenarios and discuss a case study.

Resource links to a video, satellite images, data, and photographs of glaciers provide emerging earth scientists the opportunity to examine how the ice has been retreating over the years. A data table is included for pupils to record...

Here is an interesting resource which describes different kinds of wood and their uses. There is a table with six different types of furniture wood listed, and the number of worm holes found in each one. Based on the information in the...

How can you tell if something is made of metal? Use a table of data and a science experiment to determine which items are made of metal. The experiment requires adult supervision, as it instructs third graders to build an electrical...

Two activities explore the concept of size, especially small sizes down to the nano. Scholars practice determining volume, mass, and density and calculate exponential increases and decreases. They then predict and test the effect of size...
