Students explore physical and chemical changes. For this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Students investigate sound waves and they build audio speakers. In this audio speakers and sound lesson plan, students explore how to make quality audio speakers. As a team they build their own speakers to have clarity in sound, quality...

Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...

Students relate the concept of density in relation to the rocks that make up the Earth. They determine the density of various rock specimens and answer assessment questions.

Students participate in a lab to verify Boyle's Law using applied force (weight) to do work on a closed isolated system of air. "Elasticity of Gases Apparatus, BASIX" from Sargent-Welch is the syringe apparatus used to measure volume...

Young scholars use scientific measuring tools to collect and use scientific data. They determine the density of four different objects by using their data to explain why objects have similar/different densities even though they are both...

Students have the opportunity to observe, measure and analyze the density of aerosol shaving creams and foams generated from shampoo and dishwashing liquids or detergents.

Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Middle schoolers predict and test the porosity of sediments with particles of different sizes. They name two objects that they think has pores. Students define the term porosity and pores. They comprehend that an aquifer is the porous...

Students calculate whether or not a mole of M&M's fill their high school. They practice factor-labeling, define a mole, and calculate the number of cubic feet per mole of M&M's. To answer the question they measure and calculate...

Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Students examine icebergs and how they are suspended in water, why ice floats, the melting process of an iceberg, and the floating behavior of ice compared to that of a cork through a lab activity.

Students discover plant chemical processes through three lab activities. Overheads, data sheets, and teaching procedures provided for the unit covering photosynthesis, respiration, and transpiration.

Fourth graders conduct a lab activity that measures the factors that change the swing rate of a pendulum. They create a hypothesis and test it during the experiment. They record their observations using the recording sheets and journal...

Student measure mass to discover how pennies have changed in their composition. In this measurement lesson, 8th graders investigate through an open-ended problem to discover how the US pennies composition changed in the 1980's.

Young scholars examine genetics and the DNA of a kiwi.  In this DNA lesson students complete a lab to extract DNA and interpret their results. 

A hands-on activity which allows students to learn about cellular respiration. This lesson contains a range of investigations testing the rates of cellular respiration to demonstrate the relationship between metabolic rates of...

Pupils confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.

Young scholars practice measuring the correct volume using micropipette. In this biology instructional activity, students determine the correct micropipette tip to use when transferring fluid. They convert metric volume from one...

For this viscosity and density pre-lab worksheet, students define these two terms and determine how to find relative viscosity and the volume of an irregular shaped solid. This worksheet has 13 short answer questions.

Learners observe the process of transpiration in leaves. They measure how much water a leaf gives off in a 24-hour period, calculate the volume, and answer discussion questions.

Students apply measurement skills using the metric system. They explain the process of isolating DNA from other cell contents. They apply knowledge of cell structure to explain the process of isolating DNA.

Students estimate the live mass of dinosaurs. Using dinosaur and modern animal models, students use simple displacement methods to calculate the volume of the models. They calculate the masses of each model. Students compare the...

Learners measure water and make predictions about efficiency.
