My Angle on Cooling: Effects of Distance and Inclination
Learners discuss what heat is and how it travels. They discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
Curated OER
Mirror Symmetry/Mirror Images
Young scholars explore lines of symmetry in geometric shapes. In this geometry lesson, students construct angles using mirrors and rubberbands, then predict the number of images that will appear in the reflection. Young scholars...
Curated OER
Solar Car Series: Angle/Energy Amount
Does the angle of a solar panel change the output? Emerging engineers find out! Demonstrate for your class how they can angle a straw to match the angle of light rays coming from a source. Then turn them loose to experiment with the...
Curated OER
Measure Up!
Students examine parallax and angular measurements. In this investigative lesson students calculate distances of objects and map their results.
Curated OER
Reflections Of
Students create angles using mirrors. In this angle reflection lesson, students draw angles, then use mirrors to create angles using reflections and measure the new angles.
Curated OER
Reflection of Light With Two Plane Mirrors- Double Mirrors Placed at a Number of Angles
Students place two plane mirrors at different angles to experiment with reflection. They make kaleidoscopes and periscopes.
Curated OER
Measurement via Triangulation
Students utilize triangulation techniques to determine altitudes of objects. An altitude locator is constructed and used to determine the height of a building or a tree. Tangent tables and formulas provide the ratio for the formula to...
Curated OER
Adhesives: How Sticky is Your Tape?
Students test the adhesive strength of different tapes. In this adhesive lesson, students conduct an experiment to test the shear strength of the adhesives, take measurements, record data, and draw conclusions to explain each product's...
Curated OER
Only the Shadow Knows
Young scholars become familiar with the causes for formation of shadows. They create shadows, compare the size and shape of the shadow with the actual object, engage in shadow play theatre, and discover what happens to shadows when there...
Curated OER
Toting the Log and Lifting the Babe
Students use simple machines that demonstrate force, friction, work and power. They investigate and explain simple machines.
Curated OER
How Tall is that Tree?
Students apply their math skills to develop an accurate estimate of the height of a tall tree. Three different methods are outlined. All grade levels should be able to perform the shadow method and the proportional method.
Curated OER
Light
Students examine how light waves travel. In this properties of light instructional activity, students observe how light travels in water, how light is reflected and refracted, and how light is pure energy.
Curated OER
Landslides!
Learners discover soil and Earth movement by experimenting in class. In this Earth Science lesson, students utilize a stream table, soil, graduated cylinder and water to create a re-enactment of a landslide. Learners simulate different...
Curated OER
Data-gathering Activities Relating to Trees in Their Environment
Students gather data relating to trees in their environment. In this biology lesson plan, students determine heights of trees and their ages. A canopy map will indicate optimal growing areas for the tree.
Curated OER
Beaches of the Delaware Estuary
Learners examine estuaries in Delaware. They, in groups, gather samples of water to find organisms and identify them.
Curated OER
Wings and Othe Things
Students work in groups that are engaged in different activities at different times. They watch the video "Madagascar" and collect data pertaining to the Fish Eagle's arm spam. They work together to perform mathematical computations...
