Middle schoolers investigate the concept of erosion by water in a problem solving activity. In small groups, they are assigned either sand, potting soil or rocks to construct a mountain that will hold up to a sprinkler can of water...

Seventh graders read an article and discuss questions about what they read.  In this investigative lesson students review the vocabulary and complete a worksheet. 

Students investigate the important components for a healthy trout habitat. In this fish habitat instructional activity, students discuss how the aquarium will simulate a trout's environment in nature. Students complete a trout...

Learners research the solar cycle. In this Science lesson, students use the internet to investigate the solar cycle. Learners produce a spreadsheet and graph from the information collected.

Young scholars observe the changes a class tree goes through as the seasons change and record observations in journals. They investigate changes in the weather, changes in the length of the day, and how that affects people. They create...

Students investigate speed as an important variable regarding force of an impact. Students roll a car down a ramp and into a block of wood. The distance the car travels, the time until impact and the distance the block moves are...

Students engage in a investigation of the types of meals that astronauts eat in space while examining the types of nutritional elements needed for optimum physical tasks in space. They are given different foods and then document the...

Natural human interest in patterns and algebraic study of function notation are linked in this introductory unit on the properties of sequences. Once presented with a pattern or situation, the class works through how to justify...

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

Students explore the factors that affect how long coffee stays hot. They develop a question and a testable hypothesis for one factor such as initial temperature or size of opening of the container. Then they design and conduct an...

Students must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."

Students construct a pendulums and experiment with what variables change or effect the rate at which they swing through an arc. They are assessed on scientific inquiry including the following skills: observation, data collection,...

Students design and conduct and experiment to determine how invertebrates react to an outside stimulus such as light and other stimuli. Student must develop a clear plan of action, collect data in an organized manner and analyze their...

Students explore the relationship between the force applied to a spring and its stretch. They design and conduct an experiment to determine the stretch of spring with 15N of force without having an actual 15N mass.

Students determine which of three beverage samples contains the most vitamin C. They then apply their knowledge to an additional situation. Students use beverages that have a large, definite difference of vitamin C content to...

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 act as chief research scientists with the responsibility of testing a new drug. Students design a controlled experiment to test a hypothetical experimental drug. Students write a clear, concise, and detailed plan to present to a...

Learners measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.

Study explore the motion of maple seeds and design experiments to explain their spinning flight patterns. They make observations, explain ideas of motion, use models, analyze previous reports and experiments, identify relevant factors...

Students design and conduct a scientific experiment to test which of four antacids would be most effective for neutralizing acids. They rank the antacids in order from most effective to least effective and explain how they determined...

High schoolers plan, design, and carry out an experiment to determine an empirical formula for a hydrated salt X that tell students when all the water has been removed from hydrate crystals.

Students design and conduct an experiment to compare the water-holding capacity of sand, soil, and moss. They measure the change in weight for each material after adding the same amount of water to each material.

Students examine pollen and fibers taken from a garment. They analyze pollen from new hybrids and compare it to the samples from the garment then make individual conclusions concerning the specific historical authenticity of the garment.

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...
