Fourth graders examine the physics behind and uses for inclined planes, screws, and wedges. They determine examples of how these simple machines are used in daily life. Working in three small groups, they move from station to station...

Students explore the theory of simple harmonic motion (SHM) by performing hands-on, practical application experiments. In this harmonic motion activity, students use strings of various lengths and bobs of different weights to create a...

Learners explore naturally magnetic elements. In this magnets lesson, students examine the periodic table of elements. Learners discover the parts of an atom and determine which three elements are magnetic.

Students investigate simple machines. In this simple machines lesson, students study how simple machines work. Students determine the function of various simple machines.

Students participate in an online activity to determine how objects heat and cool. They determine what objects best serve as thermal insulators.

Students participate in an online lesson to determine that different plants and animals are found in different habitats. They use food chains to show feeding relationships in a habitat, and see that nearly all food chains start with a...

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 name appliances that use electricity. They construct a simple electrical circuit. They predict whether a circuit work. They name components of an electrical circuit.

Students exercise their muscles to explore concept of heart rate and to explain how blood supplies muscles with oxygen.

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 construct a food web to identify producer, consumer, herbivore, carnivore and predator. They complete an online activity collecting plants and animals and arranging them in the web. They describe the interdependence between...

Students, in groups, design and construct an air car capable of acceleration. They view a video on acceleration, test their cars and make adjustments as desired.

Learners form an understanding that there are many different types of sound. The core concepts are presented in the most basic form for elementary school. Also students investigate how sound travels.

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 identify that there are conventional symbols to represent the components in circuits. Students use these symbols to draw diagrams of circuits. They are reminded that electric circuits can be drawn in diagrams using symbols. ...

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 compare the properties of rocks. They identify objects made of rocky materials such as walls, sidewalks, etc. Students describe and group rocks based on their characteristics.
