Fourth graders investigate the principles and uses of gears, and examine how gears can be used to alter the direction of motion or the speed of an object. They observe two cars with different sized wheels roll down an inclined plane,...

In this physics review learning exercise, students review vocabulary words associated with speed, acceleration, Newton's Laws and simple machines, work and energy, magnetism, electricity, and harmonic motion and light. This learning...

In this wave worksheet, students compare the different ways a wave can react: absorption, reflection, refraction, and diffraction. Students also read about constructive and destructive interference. This worksheet has 13 matching, 10...

For this waves worksheet, students read about the ways waves react depending on the boundary they encounter. They read about natural frequency, resonance, phases and interference in waves. They match 13 terms with their definitions, they...

In this triboluminescence worksheet, students use wint-o-green Lifesavers to observe a chemical reaction that gives off light. They break a lifesaver up with a hammer and make observations and they chew a lifesaver and make observations....

In this erosion deposition worksheet, learners fill in 36 blanks to complete sentences about the formation of soil, the forces of erosion, physical and chemical weathering, sediments and soil deposition.

In this black holes worksheet, learners solve three problems about black holes using given equations for determining the temperature of the gases in a black hole and the visible light from the black hole at given temperatures.

Middle schoolers conduct experiments. In this weather lesson, students review what they know about weather elements such as cloud formation and storms. Middle schoolers conduct demonstrations and learn how lightning strikes.

Students investigate energy. In this Physics instructional activity, students explore different sources of energy: heat, nuclear, and chemical. Students sing an electricity song.

Students use an inclined plane to move a heavy load.

Young scholars explore plants and recognize that they are living things that require light and water to grow; students identify, name and match the parts of plants.

Students examine ways for people to stay healthy, such as exercising and eating right.

Students participate in a demonstration and complete an online activity that illustrates the earth orbits the sun once a year, and that the moon takes approximately 28 days to orbit the earth.

Learners examine pictures of different animals and decide if they eat meat and/or plants. They inspect models of pairs of upper and lower teeth and discuss which teeth are most useful for cutting grass and tearing meat.

Students compare the properties of rocks and relate these properties to their use. They perform a virtual experiment to describe and group rocks on the basis of their characteristics.

Students participate in sports activities that relate to motion, velocity and momentum. They produce a PowerPoint presentation after researching the activities.

Students observe the chemical reaction that occurs when salt is put on ice, and use the energy that is released to make ice cream.

Students identify the main parts of the human body. They point to various parts of their own body, cut out pictures of humans and animals and sort them into the two categories, discuss the differences between animals and humans, and...

Students examine the topics of ocean waves, currents, and tides. They locate and label ocean currents on a world map, conduct experiments, analyze key vocabulary, view demonstrations and record the data, and complete handouts.

Fifth graders simulate the three primary types of fault movement lateral fault, reverse fault, and normal fault by positioning their hands and applying pressure to them to observe the similar action taking place in the Earth's crust.

Students examine the motif of spinning and weaving in myths and folktales. They read various myths, complete a WebQuest, develop a mind map of story elements, and write an original "spider" story.

Learners design and make a flying device. They work in small groups to brainstorm ideas for the design of their device. They choose an idea or combination of ideas to use for their design and create a sketch of their design. The students...

Students explore the ways that engineers study and harness the wind. They study the different kinds of winds and how to measure wind direction. In addition, students learn how air pressure creates winds and how engineers build and test...

Young scholars investigate the engineering design process and the relationship between distance, time, and speed. Using a generic car base, small groups design a device that will protect an egg on or in the car as it is rolled down a...
