What is an inference, and how can you use textual evidence to create one? Introduce your developing readers to the world of inferencing with this presentation. Terms are defined, and several examples are shown. The class works together...

Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them. They make predictions that can be answered through scientific...

Middle schoolers explain the difference between a closed circuit and an open circuit. They construct simple to more complicated series and parallel circuits. They explain the difference between a series and parallel circuit.

In this V, R, and I in parallel circuits worksheet, students calculate the total current, total voltage, and total resistance. Students match the correct term with the correct definition. Students also label several diagrams of series...

Students construct their own magnet and wire device. In this inquiry lesson, students investigate the factors affecting the strength of magnetic forces. They manipulate different variable to determine their effect.

Light and sound go hand in hand. Pupils set up a system that will emit sound when a laser is directed at a photodiode. Various objects, such as a comb and talcum powder, allow for modulation of the laser beam. Individuals also...

It's time! The fourth lesson in a five-part series has teams of scholars build a circuit for an alarm. A switch lets them turn the alarm on and off and allows them to hide the alarm—just as long as they don't hide it in the classroom!

From windows that tint themselves to OLED technology, electrochromic polymers are redefining our ideas about conducting materials! Introduce your chemistry class to the emerging trend with an exciting lab activity. Budding materials...

Some things are hard to resist. Small collaborative groups build circuits and calculate the voltage using Ohm's Law. Budding engineers explore the connection between the voltage across different resistors and linear...

Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...

Sixth graders explore and discuss how several electrical devices work and what energy conversions occur in each device. They connect a zinc strip to a copper strip with alligator clips and wire, immersing each strip in lemon and check...

Students measure the electric potential of 9 volt batteries using oscilloscopes. They draw a diagram of the front panel of the oscilloscope, conduct the experiment, and create a graph of voltage versus the number of batteries.

Students construct a sound speaker. In this technology lesson, students use magnet wires, a phono plug, a battery, and sandpaper to construct a homemade sound speaker.

Students investigate a series circuit. In this physical science instructional activity, students use a battery, switch, and light bulbs to build an electrical circuit. Students identify the standard symbols being used in electric circuitry.

This lesson provides students with a lab experience during which students construct a basic electric circuit and use it to explore dexterity skills. A chance to construct and operate a tool that extends a person's grasping ability and to...

Students experiment and discuss circuits and how they work. In this science lesson, students construct a telegraph machine using cardboard, wires, battery, electric tape and masking tape. They investigate what happens as the circuits...

In this interactive vocabulary worksheet, students answer 10 multiple choice questions based on their knowledge of car parts and their definitions.

Students determine what a resistor does as they construct parallel circuits. For this circuitry lesson, students experiment with batteries, alligator clips, a resistor and a three-way switch to find out what a resistor does. They...

In this water on planetary surfaces worksheet, students read about the Galileo spacecraft and the surface of Jupiter's moon Europa. They read about the energy needed to keep the water in a liquid state on Europa. Students solve 4...

In this circuits worksheet, students follow directions on how to make a light bulb light and answer questions about it. Students answer 1 question about an insulator and 1 about a conductor.

Pupils see how the properties of salt affect the color of flame, the flow of electricity, and the freezing temperature of water. They identify salt and sugar crystals under a microscope and discuss various practical uses of salt.

Eighth graders model rheostats to see how they work.

Pupils discover different types of energy. In this energy source lesson students compare different types of energy, renewable and nonrenewable. Pupils answer questions about the different types of energy and their impact on the environment.

Students explore series and parallel circuits. In this physics lesson, students construct a simple circuit and measure its maximum current. They construct their own voltmeter and ammeter that operates at a specified range.
