Students investigate gases and liquids. In this states of matter online lesson, students examine how evaporation plays a part in the transition of liquids into gases as they watch a kettle of water boil and then work in small groups on...

Learners identify and explain the parts of a flower and their role in the life cycle of flowering plants. In this online plant biology lesson, students explore the processes of pollination, seed dispersal, and germination. Extension...

Students practice the 4 question strategy to form more questions and develop further experiments. The four questions are engage, explore, explain, and elaborate. They use the 4 question strategy on an investigation involving the mass...

Students build a model of a submersible that will allow them to explore ballasts and how they operate.  In this hands on lesson students participate in an activity that shows them how to control buoyancy.

Students explore modeling of geologic structures in experiments. They study how compressive and tensile forces produce these structures. The compression makes the flatlying strata shorter and tension make the strata longer.

For this levers worksheet, students read a one page information text about the three classes of levers. Students then analyze 10 pictures of simple machines and circle the fulcrum point. Students classify each machine according to the...

Students explore simple machines and demonstrate thier acquired understanding by building a simple machine.

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 examine how physics help high jumpers break records. They discuss the phases of the high jump, gravity, and center of gravity, and conduct an experiment to determine whether they can improve the height of their jump.

Students collect data and describe how and why the high and low tides change from day to day.  In exploring tides lesson students study tides by taking notes, recording data and analyzing their findings. 

In this properties of air worksheet, students experiment with a jar, a plastic bag and rubber bands to simulate that air takes up space and exerts pressure. They make observations and answer questions about their experiment.

Students explore the different types of magnets and their common uses.  In this magnets lesson students create their own magnets. 

In this science experiment worksheet, students mix borax, custard powder (pudding mix?), glue and water to make a bouncy ball. Students carry out bouncing and stretching investigations.

Learners use an online interactive to launch a rocket from earth. They have control over the angle and thrust of the rocket to discover the relationship between the two.

Learners examine how micro-organisms are living organisms that are often too small to be seen. They explain that micro-organisms may be beneficial or harmful.

Young scholars explore the effect of water, temperature and light on plant growth. Students are asked if they remember the LAW for plants. This is Light, Air(temperature) and Water, which all plants need for growth. Young scholars are...

Students place words describing a range from cold to hot on a scale. Using those words, they identify places on Earth which are cold, hot, freezing or boiling. They practice using and reading a thermometer with three different beakers...

Students participate in an online lesson showing that gases are formed when liquids evaporate and that when a gas is cooled, it condenses to form a liquid, and gases move and flow more easily than liquids, and how gases differ from solids.

Students engage in a lesson to investigate some of the properties of sound. They create sounds and listen to the vibrations that are made while listing all the sounds that are heard. This is done while the eyes are closed to strengthen...

Students form their own hypothesis about the relationships between force, mass, and acceleration for their dynamics cart system. They collect data and express it in a graphical format to visualize the relationships.

High schoolers construct various types of paper airplanes, exploring action and reaction forces by conducting a paper airplane rodeo. Students then discuss how Newton's Third Law of Motion affected their planes.

Seventh graders progress through the Science Court: Gravity CD-ROM program. They read about and discuss how gravity was discovered. They complete review worksheets in preparation for the test.

Young scholars see the difference between weight and mass when they examine the method of measuring each of them.

In this experiments worksheet, students determine the weight and mass of different objects. Students review variables in an experiment. This worksheet has 8 short answer questions and 11 problems to solve.
