In this atomic theory worksheet, high schoolers complete a paragraph describing the development of the atomic theory by filling in the blank with 21 terms.

In this earth science worksheet, students use the clues given at the bottom of the sheet to help them solve the crossword puzzle on weathering and erosion. They identify the various factors that cause erosion in different places.

Students explain how the elements are arranged in the periodic table. In this chemistry lesson, students determine the subatomic particles for certain elements. They research the physical and chemical properties of an element they chose.

Students discuss the Heisenberg uncertainty principle and how it applies to the subatomic world. Working in groups, they design a model that would help others to understand the uncertainty principle. Written explanations are included...

Learners identify and explain these vocabulary words: vibration, volume, pitch, particles, tuning forks, waves and matter. They explain that sound travels through gas, liquid and solid. They be

Young scholars investigate the characteristics of a clay ball.  In this particles lesson students examine what happens to a ball of clay when it is dropped from different heights. 

In this elements and ions instructional activity, students complete a table given an element, the symbol, or the number of subatomic particles and they must complete the rest of the table. The do the same for five ions. They also write...

Students identify the location and change of the subatomic particles of an atom. They name the three subatomic particles. Students review what they can recall about subatomic particles. They are given a worksheet on the subatomic...

Young scholars examine various soil samples in groups. Using the samples, they identify the characteristics of them and calculate percolation and infiltration rates. They use this information to discover why some species can survive in...

Students discover how and why the settling rate of particles differs with the size of the particles. Using different soil samples, they calculate the amount of time it takes for a sample to settle in water for up to forty minutes. They...

Students describe how radioactivity relates to alpha and beta particles. Using their properties, they write a descriptive paper about the gamma rays and alpha and beta particles. They calculate q-values and the half-life of a given...
