Sounds in Strings
How many of your pupils play an instrument? A musical science lesson will help all of them understand how string instruments work. Young scientists construct a string-and-pulley system to test frequency and pitch. The lesson ends with a...
Magic of Physics
Wave Machine
Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.

Testing a New Drug 1
High schoolers act as chief research scientists with the responsibility of testing a new drug. Students design a controlled experiment to test a hypothetical experimental drug. High schoolers write a clear, concise, and detailed plan to...
Curated OER
Red Means Danger
Students describe some common pests. They study three levels of pest control from the IPM pyramid.

Ketchup Lab
In this ketchup worksheet, students investigate the thickness of different types of ketchup. They hypothesize, identify their independent and dependent variables, test their hypothesis and write conclusions based on their data.
Curated OER
Making Connections-Review Experimental Design and Homeostasis
In this experimental design and homeostasis instructional activity, students complete 20 sentences with key terms about designing experiments, gathering data, graphing data and determining controls. They also complete sentences about...
Curated OER
Study the Fizz
Students experiment to determine which bottle of soda has more dissolved carbon dioxide. In this solutions lesson plan, students use the scientific method to test the amount of carbon dioxide in bottles of soda. They identify and explain...

Experimental Design Practice
In this experimental design worksheet, students are given two experimental scenarios to read. They answer questions about each including finding the hypothesis, the independent and dependent variables and controls. They design a graph...
Curated OER
Examine the Data
Seventh graders examine a teacher-created database and identify specific variables and develop hypothesis statements as to their possible effect. They create a summary statement either proving or disproving their hypothesis.
Curated OER
Interpreting Data-Working with Controls and Variables
Students review the meaning of control and variables, and state difference between dependent and independent variables. They complete a worksheet with the definitions and complete problems that show their understanding.
