Did you see that or did I imagine it? Optical illusions are often created with mirrors and lenses, and here is a presentation that covers many different types of mirrors and lenses and how they work. Flat, concave, and convex mirrors, as...

Bring the sun to your class! Young scholars analyze actual solar wind data in the second lesson plan of a five-part series. Their analysis includes speed, temperature, and density data.

Is containing a conflict possible in the Horn of Africa? Young peacekeepers engage in a simulation that examines the multi-faceted conflict that exists between the countries of Ethiopia and Eritrea. Representatives from ten countries in...

Students investigate angles through construction. In this geometry lesson, students use a protractor to identify the measurement of an angle. They identify angles cut by a transversal and two parallel lines.

Students construct ratios using the hand as data. They use examples of cortical and trabecular bone found in the long bones to measure circumference, diameter, length, and weight of long bones. They perform computations using growth...

Students examine the problem of groundwater pollution. In groups, they develop a solution to solve the problem of a local polluted water source. They also practice measuring the space between sediment particles and the rate of water flow.

Students use the song Row Row Row Your Boat to help them learn patterns and expressive movement. They recreate the movement over and over until it is a pattern and they feel comfortable doing it.

Students build a sundial to measure the local noon time. In this third grade science lesson, students build a sundial out of common materials and align to measure the local noon. This lesson is a hands-on tracking of the sun, and allows...

Ninth graders explore how electricity is created and distributed through alternative production methods. Students participate in hands-on activities, research, lecture based instruction, and CD ROM resources.

Students are introduced to the concepts of perimter, diameter, circumference and measurements. In groups, they complete two worksheets in which they determine if the ice dimensions make a difference in the way it floats. They discuss...

Sixth graders investigate the area of polygons. In this geometry lesson, 6th graders calculate area of prisms using geometric formulas. They work with prisms and other rectangular shapes.

In this physics worksheet, students determine the density of irregular solids using water displacement method to complete 7 problems and short answer questions.

Students solve real life situation using the Pythagorean Theorem. In this geometry lesson, students calculate the length, midpoint and slope of segments. They solve word problems using properties of square roots.

Students discover how light reflects off surfaces. In this hands-on demonstration, students examine how variations in color are produced by light interference.

Eighth graders engage in hands-on activities to determine the surface areas of various objects. Using boxes, they cut them so they can lay flat and measure all the various shapes, which can be calculated and added together to equal the...

Students explore wheat. In this bread making lesson, students make their own loaf of bread and discover the history behind wheat. They work in pairs to follow step-by-step instructions for making the bread. This lesson includes a...

10 this geometry instructional activity, learners identify the different angles created by polygons and name the shape created based on the number of sides. There is an answer key.

Eighth graders complete math problems given in this lesson, where they find the perimeter and area of specific figures. They estimate the perimeter and area of shapes and figures and then complete the mathematical formula to find the...

Eighth graders record the temperature change of the beakers. In this general science lesson, 8th graders create their own data table for recording observations. They discuss experimental results and cite real life applications.

In this perimeter word problems worksheet, students enhance their understanding of perimeter by solve the six word problems.

Students evaluate the importance of hormones in living things. In this biology instructional activity, students experiment on carrots to differentiate how humans and plants reproduce. They collect data from experiment to answer analysis...

Fifth graders discover in hands-on activities the relationships between the measures. They work in groups to create conversion tables using familiar measuring tools. Students solve problems requiring conversions.

Students use their hands, feet, computer, and rulers to measure the perimeter of objects. For this measurement lesson plan, students measure objects around the room and computer generated shapes.

In this literature and science worksheet, students listen to a family member as they read "Bear Shadow." They conduct experiments that with light, shadows, and measuring tools before recording the date they did the experiment. They...
