Introduces your class to the types of loads experienced by a bridge. Groups calculate the ultimate load combinations to determine the maximum load requirement. Using this information, builders then determine the amount of material...

An outline walks your scientists through the steps of the scientific process. It begins by taking a general idea and developing a hypothesis based on related factors. Each investigator then plans a method for testing the hypothesis,...

Here is a thorough exercise in forming hypotheses for scientific investigations. Young scientists consider factors that may be related to the question they would like to address. They think through measurable changes that may result from...

Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

Experimentally, come up with a study design. Learners hear about different types of study designs, observational studies, and experiments. They identify the subjects, response variable, treatment, and whether there was a cause and...

Energy conservers investigate gravel size to discover if it impacts the amount of oil recovered in the extraction process. 

Three, two, one, blast off to a better understanding of force and motion with this exciting science lesson! Beginning with a discussion about rockets and gravity, young scientists go on to complete a series of worksheets about net...

Space, the Final Frontier. The nine NASA-created challenges in this unit are designed to teach class members the engineering design process. Each challenge comes with teacher and student pages that can be used individually or as a...

In this scientific investigation worksheet, students conduct scientific investigations on what happens to the speed of a marble when the height of a ramp is changed, what happens when you add salt to water, and 3 other experiments....

In this lab design and lab skills worksheet, students answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...

Using a simulated air sample, environmental or earth science pupils examine the components. You will need to prepare the faux air by using a hole punch and various colors of construction paper. Each color will represent a different...

Don't melt away! Pairs investigate different insulation materials to determine which one is better than the others. Using a low-temp heat plate, the teams insulate an ice cube from the heat source with a variety of substances. They...

More than 90 percent of the people in a building have come down with an illness, and it is your job to investigate. Teachers give scientists the data needed to decide what is important and how they can solve the mystery....

How likely is it that the school cafeteria will serve chicken tomorrow? Discover the concept of probability with the roll of the dice. Pupils evaluate the liklihood of several statments about everyday life. Then, a mathematical...

Dressing for success is not always about looking sharp. Sometimes it is about staying warm and dry. Present your class with an activity that challenges groups of pupils to design a layered material for blizzard conditions. The teams test...

Get things moving with this extensive collection of physical science resources. Covering the fundamentals of measurement, graphing, lab safety, and experimental design as well as the specific scientific concepts...

Young mathematicians investigate the use of symmetry in graphic design. After first learning about reflection, translational, and rotational symmetry, children use this new knowledge to identify symmetry in letters of the...

Amateurs of alternative energy build a mini parabolic-trough solar energy collector and use it to heat water. Temperature is recorded over a three-minute period and the data is graphed and analyzed. Note that in order to paint aquarium...

In this science worksheet, students write what they want to discover and identify what they feel will happen. Then they design an experiment and write the steps for it in the space provided. Students also create a data table or chart...

Let me get an angle on this! Investigate the orientation of a photovoltaic panel and its effect on efficiency. By using a light source, learners collect and plot current output to determine the ultimate orientation. The resource includes...
