Students investigate friction force on a variety of objects such as bricks and cardboard boxes. They use a force probe to collect data on the changes in force required to drag the objects across a variety of surface types.

Young scholars investigate wind speed. In this wind instrument lesson, students build an anemometer to measure wind speed and discuss the importance of wind speed knowledge in various professions. 

Students investigate the adhesion conditions and surface for using post it notes. In this post it notes lesson plan, students discover the adhesive properties, test the notes for strength, and interpret data and draw conclusions.

Students study the process of stratification and seed dormancy.  For this germination lesson students prepare a medium in which to grow  seeds.

Students collect and interpret data to make predictions about the levels of ozone in the atmosphere. Using the internet to collect data students use their collected data to create a line graph for analysis. Students make mathematical...

Middle schoolers research the conditions in which molds thrive. They apply the scientific method to develop a hypothesis, conduct research and test results.

Seventh graders hypothesize about the number of drops of liquid that can be placed on a penny before it spills over. They examine both the concept of devising a hypothesis and the idea of surface tension. They determine the difference...

Learners determine the power dissipated in the combination of two resistors connected in series to a 6 volt battery. This task assesses students' abilities to develop procedures for an investigation, develop a plan for recording and...

Students design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme...

Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...

In this earth science quiz worksheet, learners attempt to guess the name of the rocks based on the descriptions that are given on the page. They determine the names of 10 rocks that are igneous or sedimentary, and check their work with...

Students experiment to create a plastic solution. In this science instructional activity, students use sodium borax and polyvinyl alcohol to create their solution, then identify, discuss, and chart observations on the end product.

Students explore distance a toy car travels by changing the amount of batteries used to power the toy car.  In this force and motion lesson, students calculate the average speed of a car while investigating the power from various...

Young scholars construct and test balloon rockets and a model rocket. In this rocket science instructional activity, students use an inquiry-based method to master balloon rockets and have a shoot-off with the goal of attaining the...

Students conduct an experiment using leaf packs.  In this leaf lesson students complete an activity in groups and complete a handout. 

Seventh graders determine what makes a battery work. In this battery lesson plan, 7th graders brainstorm ideas about how they think batteries provide energy. They perform an experiment in which they work as a team to assemble a battery....
