Students recognize the concepts of the five general types of chemical reaction: combination, decomposition, single replacement, double replacement and combustion. They practice classifying chemical equations and determine the moles in a...

Ninth graders do a worksheet on how to balance chemical equations.

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Hop into a resource on Beer's Law. A PowerPoint presentation introduces Beer's law as part of calculating bone density from X-ray images in the sixth lesson in the series of seven. Individuals work on practice problems with this law and...

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

Objects may be more linear than they appear. Scholars investigate the relationship between the number of bone mineral density scanners in the US and time. Once they take the natural logarithm of the number of scanners, a linear...

Present the class with a question on whether the water level of a pond will rise they take a large rock out of a boat and drop it into the pond. Groups come down on all sides of the question and try to justify their answers. The activity...

Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on water or not, based on density, explain why some objects sink or float based on...

Middle schoolers develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Students calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.

Learners review balancing chemical equations. In this chemistry instructional activity, students calculate moles of an unknown substance based on stoichiometric relationships in the balanced equation. They cite applications of...

Students create a foldable to help them remember topics on chemical compounds. In this physical science lesson, students differentiate ionic and covalent compounds. Given certain compounds, they identify whether it's ionic or covalent.

Students determine the muzzle velocity of projectile launcher. In this physics lesson, students compare the pendulum method and kinematic method in calculating the initial velocity. They analyze data and discuss results in class.

High schoolers conduct labs to gain an overview of chemical reactions. They observe examples of synthesis, decomposition, single displacement and double displacement reactions. They identify certain products by the use of litmus and...

For this cell energy worksheet, learners answer questions about the processes of photosynthesis and cellular respiration. They compare the two using a Venn diagram.

Students make predictions about the global temperature of the earth and to see how this is dependent upon a number of variables. Students visualize how changing parameters can impact the global temperature of the earth.
