Students explain the effect of water, temperature and light on plant growth.

Students explain that mirrors reflect light. They examine how when a beam of light is reflected from a surface, its direction changes.

Fourth graders investigate the principles and uses of gears, and examine how gears can be used to alter the direction of motion or the speed of an object. They observe two cars with different sized wheels roll down an inclined plane,...

Students use simple machines that demonstrate force, friction, work and power. They investigate and explain simple machines.

This machines PowerPoint reviews effort and force in relation to work and informs students about different types of machines and the different ways forces are applied and how they work to increase efficiency.

Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.

Young scholars explore plants and recognize that they are living things that require light and water to grow; students identify, name and match the parts of plants.

Learners complete food chains for organisms in three environments. They use copies of the Habitat worksheet. Students review the food chain terms with the teacher. They research related food chains, and interlink these to form a food...

Students investigate micro-organisms with an on line activity. In this micro-organism on line lesson plan, students identify bacteria, viruses and fungi projected onto a white board. Students work in groups and use a computer and an on...

Students compare the properties of rocks and relate these properties to their use. They perform a virtual experiment to describe and group rocks on the basis of their characteristics.

Students use a chart of the six simple machines and become aware of how the machines improve our ability to meet the following needs: shelter, food, water, and transportation. Students use model cars to experiment with force. They divide...

Students investigate how mirrors reflect light. In this reflection lesson, students draw the path of the light reflected from a mirror. Students construct a list of objects that are light sources.

Learners examine pictures of different animals and decide if they eat meat and/or plants. They inspect models of pairs of upper and lower teeth and discuss which teeth are most useful for cutting grass and tearing meat.

Students identify the main parts of the human body. They point to various parts of their own body, cut out pictures of humans and animals and sort them into the two categories, discuss the differences between animals and humans, and...

Fifth graders simulate the three primary types of fault movement lateral fault, reverse fault, and normal fault by positioning their hands and applying pressure to them to observe the similar action taking place in the Earth's crust.

Students use the design process to investigate physical science.  In this force and motion instructional activity, design a track to achieve a specified outcome. Students complete additional experiments with speed and...

Students examine wave formation. In this wave instructional activity, students discover how waves are formed and how the weather at sea is predicted. Students study ocean vocabulary and understand the Beaufort Wind Force Scale.

Students explore Bernoulli's principle, how it is related to flight, and the effect of lift, thrust, and drag on flight. They design and develop an experiment that tests for distance traveled by their paper airplane, and record and...

In this simple machines worksheet, students complete a chart. They look at a picture of a simple machine, draw/paste an example of each one for homework. They use a web quest to find 2 more facts about each one and write it in the chart....

Students explore the ways that engineers study and harness the wind. They study the different kinds of winds and how to measure wind direction. In addition, students learn how air pressure creates winds and how engineers build and test...

In this black holes worksheet, students read about black holes and solve 3 problems where they calculate the Schwarschild radius of one, the number of grams/second a quasar luminosity implies for another and the number of suns per year 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....

Pupils visualize the relation between acceleration and velocity in 2 dimensions. They are introduced to Newton's first law,and Newton's second law. Students work on an exploration activity where they condsider an example of a...
