Students are told that the weight of a car is equal to its mass multiplied by the acceleration due to gravity. When a car is at react on a horizontal road, there must be a normal force with which the road pushes up on the car to keep it...

Students explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces by measuring the distance that a...

Ninth graders use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on....

In this friction instructional activity, learners will read about fluid friction and examples of fluid friction. Students will also explore the role fluid lubricants have in reducing friction between two surfaces. Then learners will...

Students design and conduct experiment to determine if weight added incrementally to an object affects amount of friction encountered when it slides across a flat surface. They graph data from their experiments, and calculate...

Seventh graders explore the Laws of Motion. They define friction and explain the concept of inertia. Students explain what happens when a force is exerted on an object that is in equilibrium. They state the second and third laws of motion.

Students participate in two hands-on demonstrations to explore how friction can make objects hard to push.

Students create a model of a circuit breaker to help them explain how friction causes heat, and how current is carried.

In this movement instructional activity, students will complete 5 sentences by filling in the blank with vocabulary words associated with movement: acceleration, gravity, and speed. Then students will be given 3 units of measurement and...

Students discover what simple machines are and identify a gear, a pulley, and a lever. In teams, they build at least two models each of simple machines and challenge them with specific instruction cards. Finally, students present and...

Students build their own electric motors and use them to conduct experiments. Following a step-by-step procedure, they make wire coils by wrapping wire around disc magnets and complete the process with clay, paper clips, alligator clips,...

Eighth graders examine two different types of tires and the effects of different factors on the amount of force needed to overcome sliding friction such as when the vehicle tries to stop.

Learners use the Internet to delve into the relationship between fores and motion on a sizable object. They predict where they think the temperature and pressure be the greatest, and where the pressure be the lowest.

Learners investigate melting and cooling in a range of materials.

Learners recognize the different types of plants and animals living in a local environment. They determine how they require different habitats to live, and relate simple life processes to plants and animals found in local environments.

Students participate in an online lesson making and recording observations of magnets. They determine that magnets attract some metals but not others and that other materials are not attracted to magnets.

Learners participate in an online lesson to determine how light travels from a source, and to explain that shadows form when light travelling from a source is blocked.

Students practice sorting and classifying objects. In groups, they choose a variety of materials and describe how each one looks and feels. They must agree on how to classify each object and share their groupings with the class. They...

Students observe and record the apperacne of shadows and how their position and shpae changes during the course of the day. Students measure and record the length oof a partner's shadow at different intervals during the day. In pairs,...

Students use keys to identify animals and plants in local habitats. Students are asked if they remember what the word habitat means. Students make a list of three different local habitats and brainstorm animals and plants they might...

Students are introduced to several concepts about milk teeth and permanent teeth. They view photos of baby teeth, complete a worksheet that depicts their current tooth development and identify ways in which to care for permanent teeth.

Students discuss the properties of solids and liquids. They complete a worksheet to show the boiling and melting points of several substances and consider if these factors affect how humans use materials.

Students investigate that the sun is at the center of the solar system through role play. One student is the sun and one student is the Earth. The students then show how the Earth orbits around the sun. Students view a flashlight and...

Students observe the various living things they can find outside their playground making sure to look both on the ground and in the air. They develop a large poster Venn digram, as a class, of plants and animals that live in the air, on...
