Apply robotics to connect physical properties to chemical properties. Future engineers use robots to determine the melting points of various fats and oils. The robots can do this by measuring the translucency of the fats as they heat up.

Students classify the visual opacity of various materials, what is needed to create shadows, and classify clouds by the types of shadows that they produce.

Students observe pictures of themselves using film and discuss how they think the image is processed to produce a photograph. They are introduced to photogram paper comparing it to photograph paper but understanding that no film is...

Students classify clouds as transparent, translucent or opaque. They conduct an experiment to determine the visual opacity of several classroom objects and then conduct further observations of clouds.

Introducing ... the aerogel. The first of a two-installment series teaches young engineers about the properties and uses of aerogels. A PowerPoint presentation provides information about this unique material to help solidify the concept.

Students illustrate a First Nations' legend.  In this legend of bears lesson, students read several legends which involve bears and groups of stars or constellations. After reading, students illustrate portions of the stories....

Students develop problem-solving, observation, and critical-thinking skills. In this early childhood lesson, students explore the topic of the sun as they notice shadows and light.

Help your students write descriptive lab reports! Designed for ESL students but useful for mainstreamed kids as well, the activity prompts students to think of substances that match twenty given adjectives ("salt" for "soluble," for...

The question is posed, is it permeable or impermeable, it's up to your critical thinkers to determine the answer. This presentation provides several scientific concepts related to permeability and the properties of matter alongside...

For this online interactive reflection and refraction worksheet, students respond to 7 multiple choice and fill in the blank questions regarding the information included in the provided paragraphs.

Students explore the parts of a microscope. In this microscope lesson, students examine simple and compound microscopes. Students discover how the parts of a microscope work together to generate an image.

In this earth science worksheet, students look at the properties that are common to identifying minerals and the types of observations one can make.

Can you block the beam of light? Learners will investigate what happens to light beams when you put objects in its way. These tests will allow them to learn new vocabulary (translucent, transparent, opaque) and discover how these terms...

This resource provides information about light and shadows. In addition, there is a short quiz that can be taken.

This is the first instructional activity of this unit to introduce light. In this instructional activity, students learn the five words that describe how light interacts with objects: "transparent," "translucent," "opaque," "reflection"...

[Free Registration/Login Required] This flipchart reviews the characteristics of light and its properties. Students are given examples of reflection, refraction, and lens types. An assessment component is included.

In this activity, students examine various materials and investigate how they interact with light. Students use five new vocabulary words (translucent, transparent, opaque, reflection and refraction) to describe how light interacts with...

Students will have an opportunity to explore the school during a hunt for 3 materials that allow different amounts of light to pass through. Included in this lesson are videos showing the lesson in progress, examples of students' work,...

Kids learn about the science of light. Energy made of waves and particles called photons traveling at the top speed in the universe. What is refraction? The difference between transparent, translucent, and opaque.

[Free Registration/Login Required] This flipchart introduces fifth graders to the science of light. Principles such as transparent, translucent, opaque, reflection, and refraction are covered. Concave and convex mirrors and lenses are...

[Free Registration/Login Required] This unit introduces the relationship between light, an object and the formation of shadows.

The definitions of transparent, translucent, and opaque can be found here. The article explains how the density of a material and its ability to absorb light determine which of these three properties it has. A list of examples is given...

This lesson will explain why objects have different colors.

Learn about the properties of materials in their interactions with light, including whether they are opaque, transparent, or translucent, and which of these produce shadows.
