Students use prior knowledge of angle and lines as they conduct an experiment with a rolling marble to determine the shape of a mystery object located under a metal pie tin.

Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce...

In this light and optics worksheet, students match the light and optics vocabulary with their definitions. Students match 21 words to their definitions.

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...

Young scholars define the word dichotomous and explain why a dichotomous key is a useful tool in identifying different species. Then they look up words they are unfamiliar with or mollusk reference books so students can learn the names...

The lesson allows young scientists to use lasers and mirrors to study reflected light. A reading passage and homework question assess learning, while additional material introduces extension activities. 

Did you know some retailers use curved mirrors in their fitting rooms to make customers look thinner? Pupils view themselves in convex and concave mirrors to understand the difference. The resource includes big ideas for multiple age...

In this waves worksheet, students define 23 vocabulary words associated with the different types of waves and how waves are measured. Students complete 23 matching terms with definitions and draw the superposition of two waves shown.

In this history worksheet, students use the questions to discover meaningful science and history connections. The worksheet is meant to be viewed online to access individual answers.

Force acts on objects in mysterious ways ... until now! A comprehensive presentation explains the balance of forces acting on objects. Learners draw free body diagrams to show these invisible forces and make force calculations.

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth lesson of an 11-part series. Individuals then work...

High schoolers will determine distances to nearby stars using parallax. In this Astronomy lesson plan, students will use a web program, trigonometry, and sketches to determine the distance of stars.

Students make a simple sundial to examine the changes in shadows over time. In this sundial and shadow lesson, students make a simple sundial out of a manila folder and pencil. They observe how shadows change over time, and relate it to...

Student form and test hyptheses using indirect and direct observation. They launch marbles to determine the shape of a hidden object.

Young scholars explore and analyze the bottom structure of underwater habitats. They describe and explain what can't see through the collection and correlation of accurate data. Learners assess that technology is utilized as a tool for...

In this ketchup worksheet, students investigate the thickness of different types of ketchup. They hypothesize, identify their independent and dependent variables, test their hypothesis and write conclusions based on their data.

In this optics instructional activity, students read about how light can reflect or refract and how lenses and mirrors work. Then students complete 13 matching, 27 fill in the blank, and 8 word problems.

In this optics worksheet, learners read about refraction and reflection, lenses and mirrors, and objects and images. They answer 13 matching questions about light rays, light behavior and types of lenses. They also answer 9 questions...

Students discover the concept of bioluminescence. They identify marine animals who have use this and why. They work together to test the function of bioluminescence as camouflage.

Learners explore momentum. In this physics lesson, students perform an experiment in which two balls are released on slanted boards while learners observe which ball will go the farthest and the fastest. Students define and explain...

For this electrical circuit worksheet, students answer a series of 20 open-ended questions about AC motor circuits.  This worksheet is printable and the answers are revealed online.

Learners find the altitude of the Sun at 10 A.M., at solar noon, and at 2 P.M. by measuring the height of the gnomon and the length of the shadow at each time. They record the measurements in their notebooks for later conversion.

Students study elevation of the Sun above the horizon and the angle of the rays and their heating power.

Students construct and test balloon rockets and a model rocket. In this rocket science lesson plan, students use an inquiry-based method to master balloon rockets and have a shoot-off with the goal of attaining the highest altitude....
