Students examine technologies that already exist and record their findings in a journal. They work with students in other countries to explore alternative energy sources They publish their designs online.

Middle schoolers design a closed system to test the relationships between plants and animals. They monitor abiotic fluctuations within this living system by using a chemical test kit. They observe how living organisms respond to...

Students compare spinach. In this Science instructional activity, students construct an experiment to test fresh, frozen, and canned spinach taste and texture. Students record their findings in charts and graphs.

Students as a class create a fountain using both coke soda, and mentos candy. For this science lesson, students test which combination of coke and mentos products produce the tallest fountain. Students use the scientific method to track...

Fourth graders work together in groups to design and complete one science experiment of their choice. Following the experimental steps, they show their experiment and the results to the class in the form of a PowerPoint. They explain...

This open-ended boat building exercise is meant to be part of a three-lesson series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load line...

Students learn the trends in the current job market for scientists, find where the jobs are, the range of salaries, and the job requirements. They discover that scientists do some very interesting things, then write a letter of...

Students perform experiments to determine the nutritional needs and physical space requirements for slime mold to survive. After formulating hypotheses, they seal the petri dishes and set up the experiment along with two controls. ...

Fourth graders participate in a scientific experiment involving growing lima beans. Students plot information gathered on included charts and graphs. Students use the steps of the scientific method throughout this experiment.

Pupils investigate a problem and background information including the typical capabilities /limitations of a paraplegic. They develop an understanding of the attributes of engineering design.

Students examine the heart and vascular system and the need for artificial valves. After explaining how heart valves function, they design their own heart valves for experimentation. They predict the speed of fluid flowing through...

What does viscosity have to do with splatter? An activity shows that the viscosity of a substance is inversely proportional to the distance of its splatter. Learners conduct the experiment by collecting data, graphing, and analyzing...

Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

Students conduct a hands-on experiment with collisions between two skateboards of different masses. They are introduced to the concept of conservation of momentum in collisions and consider how their observations might help engineers...

Eighth graders design and build a gingerbread house. In this technology lesson, 8th graders research the important components of a house. They evaluate the strength of their design and suggest modifications when necessary.

Students hatch brine shrimp in a classroom experiment. In this hatching brine shrimp lesson, students participate in two-week lab in which they study how brine shrimp hatch under different conditions. They record data about the control...

Students examine an area of land and assess its suitability for construction purposes. This project requires a vast amount of hands-on experimentation, data analysis, community involvement, and job shadowing/career awareness.

Learners use the steps of the Scientific Method to develop and test their own ideas through experimentation with ants.

Students work together to design an experiment. They discover the origin of a family artifact. They analyze the data and discuss the results. They determine if the experiment is the best way to find out this type of information.

Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

Fifth graders identify, through experimentation, what properties of substance are, determine what variables tested will be, identify constants and variables of experiment, conduct experiment to conclusion with measurable, recorded...

Students define temperature and heat, distinguish between temperature and heat flow, calculate amount of heat energy released or absorbed in chemical process, and design procedure, through experimentation, to gather and evaluate data to...

Students explore how the earth is a magnet and that magnets have two "poles".  In this magnetic lesson students complete an activity by designing their own compass. 

Students think about the historical development of the scientific method. They design an experiment that replicates van Helmont's, using only specified materials. Pupils then improved upon van Helmont's procedure and also consider the...
