How quickly do animals evolve? Can comparing different samples of the same fossil answer timeline questions? Scholars use virtual labs to examine fossils and learn about stickleback evolution. They compare pelvic morphology in lakes...

Examine numbers in scientific notation as a comparison of size. The 14th instructional activity in the series asks learners to rewrite numbers as the same power of 10 in scientific notation to make comparisons. Pupils also learn how to...

Kids will compare creating fractions from pieces of paper to chips. They begin with a fractional part and work back to a whole. Then order fractions from smallest to largest. They also complete a worksheet to find the missing pieces to...

Students explore how and why local convective, possibly severe, storms develop. They examine how hailstones form and the conditions under which they form. They test mock hailstones of varying sizes to investigate the impact and damage...

Young scientists grab their measuring tapes, rulers, and yard sticks as they see how big Arctic animals really are. To conceptualize the trait of height or length, each small group will measure out the entire length of an arctic animal....

Geometric shapes make great visual models for introducing young mathematicians to the concept of fractions. Looking at a series of four circles, students are asked to determine whether or not one half of each circle is shaded. To support...

Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

Help your class determine the types of pollutants coming from vehicle exhaust. Groups use an air quality monitor to determine the emissions from different vehicles, to gain knowledge about combustion energy, and to predict how the...

To an engineer, the glass is never half full; it's just double the necessary size. The fifth installment of a nine-part technology and engineering series teaches pupils about the idea of ergonomic design. Measurements of popliteal height...

Investigate sound waves with acoustic mirrors. Using audio software, groups make recordings of musical instruments, both with and without acoustic mirrors. They compare the recordings to see the effect of acoustic mirrors on sound...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Seventh-graders solve 20 various types of problems related to ratio and rate. They write ratios in simplest form for each given statement, to compare the area of two figures, and write two ratios equivalent to each ratio. Pupils express...

Examine earthquake intensities and ways to measure an earthquake through the comparison of the Mercalli and Richter scales. After completing the pre-lab worksheet, fourth graders compare high and low intensity quakes by testing...

Learners identify their beliefs and values and compare how these values relate to those of their community. They then determine how their values affect the roles they play in different situations. A quiz about values and beliefs...

Explore informative and explanatory writing with this instructional activity. Using a cube labeled with directives to describe, analyze, compare, associate, apply, and argue the topic, middle schoolers work individually or in groups to...

Shoot and score with three basketball-themed lessons about decimals. Young mathematicians compare game statistics, make trash can hoops, and play a data spinner game to practice identifying digits and values within decimal numbers.

Inform your class about the adaptations in fish eyes: cones, lens size, endothermy, and speed of vision. The adaptations are related to diving behavior. Junior marine scientists compare the adaptations of four different fish species to...

So, this is not technically a worksheet, but rather a chapter of reading material, pictures, and diagrams introducing young biologists to the cell. Cell theory, diversity, size, and shape are described. The internal organization and...

Any first grader can master the Common Core math standards with this checklist! With each standard rewritten as an affirmative I can statement, children are provide with clear goals to work toward throughout the school...

You won't regret being stuck with this activity. By mixing a variety of household items, pupils create their own glue. They test the tensile strength of their glue and compare it to that of other adhesives.

Are brighter stars actually brighter? Turns out they are probably just closer! A presentation compares features of stars to our favorite star, the sun. In addition, solar lovers learn to classify stars based on their masses,...

Students examine poems from Latin America and the Caribbean. They compare different perspectives and subjects in the poems. They research Peace Corps volunteers as well.

Students examine the built environment and infrastructures of their community by constructing contour equipment, using the equipment, and comparing their results to current topographical maps of the same area

Students classify and compare plants using specific information, observations, and numbers. In this mathematical inquiry lesson, students use plant characteristics to describe, compare, and classify them. They attempt to develop a system...
