Grade Level Expectations | Adopted: 2005

This correlation lists the recommended Gizmos for this state's curriculum standards. Click any Gizmo title below for more information.

SB2: : Students develop an understanding that energy appears in different forms, can be transformed from one form to another, can be transferred or moved from one place or system to another, may be unavailable for use, and is ultimately conserved. The student demonstrates an understanding of how energy can be transformed, transferred, and conserved by:


SB2.1: : investigating the effectiveness of different insulating and conducting materials with respect to heat flow and record the results.

Screenshot of Conduction and Convection

Conduction and Convection

Two flasks hold colored water, one yellow and the other blue. Set the starting temperature of each flask, choose a type of material to connect the flasks, and see how quickly the flasks heat up or cool down. The flasks can be connected with a hollow pipe, allowing the water in the flasks to mix, or a solid chunk that transfers heat but prevents mixing. 5 Minute Preview

SB3: : Students develop an understanding of the interactions between matter and energy, including physical, chemical, and nuclear changes, and the effects of these interactions on physical systems. The student demonstrates an understanding of the interactions between matter and energy and the effects of these interactions on systems by:


SB3.1: : explaining that temperature changes cause changes in phases of substances (e.g., ice changing to liquid water and liquid water to water vapor).

Screenshot of Phases of Water

Phases of Water

Heat or cool a container of water and observe the phase changes that take place. Use a magnifying glass to observe water molecules as a solid, liquid, or gas. Compare the volumes of the three phases of water. 5 Minute Preview

SB4: : Students develop an understanding of motions, forces, their characteristics and relationships, and natural forces and their effects. The student demonstrates an understanding of motions, forces, their characteristics, relationships, and effects by:


SB4.1: : simulating that changes in speed or direction of motion are caused by forces.

Screenshot of Force and Fan Carts

Force and Fan Carts

Explore the laws of motion using a simple fan cart. Use the buttons to select the speed of the fan and the surface, and press Play to begin. You can drag up to three objects onto the fan cart. The speed of the cart is displayed with a speedometer and recorded in a table and a graph. 5 Minute Preview

SC3: : Students develop an understanding that all organisms are linked to each other and their physical environments through the transfer and transformation of matter and energy. The student demonstrates an understanding that all organisms are linked to each other and their physical environments through the transfer and transformation of matter and energy by:


SC3.2: : Identifying a simple food chain and diagramming how energy flows through it. and describing the effects of removing one link.

Screenshot of Prairie Ecosystem

Prairie Ecosystem

Observe the populations of grass, prairie dogs, ferrets and foxes in a prairie ecosystem. Investigate feeding relationships and determine the food chain. Bar graphs and line graphs show changes in populations over time. 5 Minute Preview

SD3: : Students develop an understanding of the cyclical changes controlled by energy from the sun and by Earth's position and motion in our solar system. The student demonstrates an understanding of cycles influenced by energy from the sun and by Earth's position and motion in our solar system by:


SD3.1: : recognizing changes to length of daylight over time and its relationship to seasons.

Screenshot of Seasons: Earth, Moon, and Sun

Seasons: Earth, Moon, and Sun

Observe the motions of the Earth, Moon and Sun in three dimensions to explain Sunrise and Sunset, and to see how we define a day, a month, and a year. Compare times of Sunrise and Sunset for different dates and locations. Relate shadows to the position of the Sun in the sky, and relate shadows to compass directions. 5 Minute Preview

Screenshot of Summer and Winter

Summer and Winter

Observe the tilt of Earth's axis and the angle that sunlight strikes Earth on June 21 and December 21. Compare day lengths, temperatures, and the angle of the Sun's rays for any latitude. The tilt of the Earth's axis can be varied to see how this would affect seasons. 5 Minute Preview

SD3.2: : observing that heat flows from one object to another.

Screenshot of Heat Absorption

Heat Absorption

Shine a powerful flashlight on a variety of materials, and measure how quickly each material heats up. See how the light angle, light color, type of material, and material color affect heating. A glass cover can be added to simulate a greenhouse. 5 Minute Preview

Screenshot of Radiation

Radiation

Use a powerful flashlight to pop a kernel of popcorn. A lens focuses light on the kernel. The temperature of the filament and the distance between the flashlight and lens can be changed. Several obstacles can be placed between the flashlight and the popcorn. 5 Minute Preview

About STEM Cases

Students assume the role of a scientist trying to solve a real world problem. They use scientific practices to collect and analyze data, and form and test a hypothesis as they solve the problems.

Realtime reporting icon

Each STEM Case uses realtime reporting to show live student results.
Introduction to the Heatmap

Time icon

STEM Cases take between 30-90 minutes for students to complete, depending on the case.

Save icon

Student progress is automatically saved so that STEM Cases can be completed over multiple sessions.

Grades icon

Multiple grade-appropriate versions, or levels, exist for each STEM Case.

Handbook icon

Each STEM Case level has an associated Handbook. These are interactive guides that focus on the science concepts underlying the case.
