Mississippi - Science: 4th Grade
State Frameworks | Adopted: 2008
2: : Use the properties of objects and materials, position and motion of objects, and transfer of energy to develop an understanding of physical science concepts.
2.c: : Determine the causes and effects of forces on motion.
2.c.1: : Force exerted over a distance causes work to be done and that the result (work) is the product of force and distance
Ants on a Slant (Inclined Plane)
Lift food using ants with the help of a slanted stick. The steepness of the stick, the number of ants, and the size of the item being lifted can be varied. Observe the effect of friction on sliding objects. 5 Minute Preview
2.c.2: : Friction on moving objects and actions that increase or decrease friction
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
2.d: : Explain how energy flowing through an electrical circuit can be converted from electrical energy to light, sound, or heat energy.
2.d.1: : Parts of an electric circuit and resulting actions when circuits are opened or closed
Circuit Builder
Create circuits using batteries, light bulbs, switches, fuses, and a variety of materials. Examine series and parallel circuits, conductors and insulators, and the effects of battery voltage. Thousands of different circuits can be built with this Gizmo. 5 Minute Preview
2.e: : Describe how light behaves (travels in a straight line, is absorbed, reflected, refracted, or appears transparent or translucent).
Color Absorption
Mix the primary colors of light by using red, green, and blue lights. Use pieces of colored glass to filter the light and create a wide variety of colors. Determine how light is absorbed and transmitted by each color of glass. 5 Minute Preview
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
2.g: : Describe how heat flows from a warm object to a cold one and categorize examples of materials that may or may not be used as insulators.
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
3: : Analyze the characteristics, structures, life cycles, and environments of organisms.
3.a: : Describe the cause and effect relationships that explain the diversity and evolution of organisms over time.
3.a.1: : Observable traits due to inherited or environmental adaptations
Inheritance
Create aliens with different traits and breed them to produce offspring. Determine which traits are passed down from parents to offspring and which traits are acquired. Offspring can be stored for future experiments or released. 5 Minute Preview
3.b: : Classify the organs and functions of the nervous, circulatory, and respiratory systems of the body.
Circulatory System
Trace the path of blood through a beating heart and the network of blood vessels that supplies blood to the body. Take blood samples from different blood vessels to observe blood cells and measure the levels of oxygen, carbon dioxide, sugar, and urea. 5 Minute Preview
3.d: : Distinguish the parts of plants as they relate to sexual reproduction and explain the effects of various actions on the pollination process (e.g., wind, water, insects, adaptations of flowering plants, negative impacts of pesticides).
Flower Pollination
Observe the steps of pollination and fertilization in flowering plants. Help with many parts of the process by dragging pollen grains to the stigma, dragging sperm to the ovules, and removing petals as the fruit begins to grow. Quiz yourself when you are done by dragging vocabulary words to the correct plant structure. 5 Minute Preview
3.e: : Analyze food webs to interpret how energy flows from the sun.
Forest Ecosystem
Observe and manipulate the populations of four creatures (trees, deer, bears, and mushrooms) in a forest. Investigate the feeding relationships (food web) in the forest. Determine which creatures are producers, consumers, and decomposers. Pictographs and line graphs show changes in populations over time. 5 Minute Preview
4: : Develop an understanding of the properties of Earth materials, objects in the sky, and changes in Earth and sky.
4.d: : Describe how human activities have decreased the capacity of the environment to support some life forms.
4.d.1: : Reducing the amount of forest cover
Forest Ecosystem
Observe and manipulate the populations of four creatures (trees, deer, bears, and mushrooms) in a forest. Investigate the feeding relationships (food web) in the forest. Determine which creatures are producers, consumers, and decomposers. Pictographs and line graphs show changes in populations over time. 5 Minute Preview
4.f: : Describe objects in the universe including their movement.
4.f.1: : Physical features of the moon (craters, plains, mountains)
Solar System
Explore our solar system and learn the characteristics of each planet. Compare the sizes of planets and their distances from the Sun. Observe the speeds of planetary orbits and measure how long each planet takes to go around the Sun. 5 Minute Preview
4.f.2: : Appearance and movement of Earth and its moon (e.g., waxing/waning of the moon and lunar/solar eclipses)
Eclipse
Observe solar and lunar eclipses as the Moon orbits Earth. The full and partial shadows of the Moon and Earth can be displayed, and the Moon can also be dragged around Earth. See what the Moon and Sun look like from Earth during partial and total eclipses. 5 Minute Preview
Solar System
Explore our solar system and learn the characteristics of each planet. Compare the sizes of planets and their distances from the Sun. Observe the speeds of planetary orbits and measure how long each planet takes to go around the Sun. 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.
Each STEM Case uses realtime reporting to show live student results.
Introduction to the Heatmap
STEM Cases take between 30-90 minutes for students to complete, depending on the case.
Student progress is automatically saved so that STEM Cases can be completed over multiple sessions.
Multiple grade-appropriate versions, or levels, exist for each STEM Case.
Each STEM Case level has an associated Handbook. These are interactive guides that focus on the science concepts underlying the case.
