A B

Next Generation Science Next Generation Science is based on the United States Next Generation Science Standards (NGSS). The series consists of full-color textbooks and full-color activity books for Grades K to 6.

Next Generation Science engages students with a highly visual presentation of the disciplinary core ideas in the textbooks and places an emphasis on applying scientific knowledge using NGSS practices through numerous scientific investigations. Next Generation Science sees engineering as an essential element of science education and as such is tightly integrated into both the textbooks and activity books.

The Next Generation Science activity books include the follow features:

• switch

• tape

• battery (dry cell)

Procedure 1. In small groups, use the circuit components to build a simple circuit with a switch.

2. Open and close the switch and observe what happens to the light bulb.

Observations Draw the electric circuit you built.

Label the different parts.

Analyze and Interpret 1. What happened to the light bulb when the switch was open? Why did this occur?

2. What happened to the light bulb when the switch was closed? Why did this occur?

).

(a) Temperature is a measure of how fast something moves. (b) We can measure temperature with a thermometer. (c) Heat can only travel through solids. (d) Heat flows from hot objects to cool objects.

3. Draw and label a device that uses electricity produced in power stations and a device that uses electricity from batteries.
