Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.

Students discover using globes. In this geography lesson plan, students use a globe to outline the original 13 colonies. Students also use a globe to measure the distance from London to New York City and determine how many days it would...

Students solve quadratic function by completing the square. In this algebra lesson, students use the quadratic formula to factor quadratics and find the roots. They graph the parabola and identify its properties.

Students explore energy. In this science lesson, students conduct an experiment in which they measure how much energy is produced by the sun. Students build a calorimeter to measure the amount of energy.

Students study the effects of deforestation. In this environmental lesson, students view a PowerPoint slideshow about the importance of trees. Students read The Lorax and discuss what the characters represent in our society.

Pupils design and launch their own rockets.  In this experimental lesson students launch their own rockets and record the various angles and distance that they go.  Each student has time to redesign their rocket and have a...

Students identify, research and interpret the national debt and deficits of the past through today and why it has risen significantly in the last 20 years. They analyze the size and impacts and discuss the various policy measures for...

Students observe a demonstration of regular soda versus diet soda.  In this exploring density instructional activity students complete a lab on density and present a PowerPoint presentations of their results.

Fifth graders compare biodiversity in their neighborhood and in the rainforest. In this biodiversity lesson, 5th graders read stories and gather information about the diversity of life found in their area and in the rainforest. As a...

Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...

Students explore the concept of fractals. In this fractal activity, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...

Students examine transformations. In this math lesson, students view and describe flips, slides, and turns. Students practice making transformations with shapes.

Learners analyze water quality and turbidity of collected samples. In this physics lesson, students conduct tests to identify the suspended particles in the samples. They explain how human activities affect water quality.

Fifth graders conduct experiments in simulated water pollution using a box of items to hold "pollutants"and an aquarium, representing a waterway. They observe how "rain" from a watering can poured into the box washes the pollutants into...

Students explore the population of grass plants in a given area. They plan and conduct a sampling activity to estimate the population of dandelions or the number of grass blades on the school grounds.

Tenth graders distinguish between chemical and physical properties and changes in matter when given specific examples. They view a video of sports activities. Students chose their favorite sport and design an experiment to improve sports...

Young scholars discuss water pollution and the Safe Drinking Water Act of 1974 after watching a teacher demonstration in which different contaminants are added to tap water. While some contaminants are not harmful to the body, in excess...

Learners comprehend what has been explored in the previous earthquake engineering design lessons, by putting their designs to the test. They are given pairs a piece of paper, and an empty plastic bottle or can. Students stand the...

Students engage in a lesson in order to create blueprints to design an original floorplan. They use graphing paper and drawing tools to demonstrate knowledge of the lesson objectives. Students label and use the right kind of proportions...

In this math learning exercise, students examine the concept of floating point arithmetic. They compare the tools of chopping and rounding to measure accuracy.

High schoolers explore the basic building blocks of our planet.  In this minerals lesson students begin the process of forensics on the basis of investigation and drawing conclusions from observations. 

In this physics worksheet, students design and build a power inverter given a schematic diagram. They answer 3 short answer questions about the circuit they created.

Students explore mean, median and mode. In this math lesson plan, students analyze temperature data and figure the mean, median, and mode of the data. Students graph the data in a bar graph.

Students investigate the relationship between force and momentum using motion detectors and sensors. In this physics lesson, students graph experimental results. They calculate impulse using the area under the graph.
