In this 2-day instructional activity focused on exponents, middle schoolers will cross the curriculum by engaging in science, history and language arts activities. Exponential growth will be explored using grains of rice on a chess...

Chemists consider a situation in which an ethanol producer needs to determine how much to add to t-butanol to prevent freezing during transport. They work in the laboratory to obtain the freezing point depression constant for the...

Explore the properties of solutions with a lab activity. Chemistry fans determine the boiling point of water, add salt to create a solution, and then repeat the process four more times. They design their own data table and then graph the...

Present polymers to your chemistry class with this practical PowerPoint. Begin with a definition and the properties of polymer materials. Branch out into diagrams of polymer structure. Consider the two general types: addition polymers...

Elasticity and viscosity. Help your class understand the similarities and differences with an introduction to viscous fluids. After describing four types of fluid behaviors: shear thinning, shear thickening, Bringham plastic,...

The health effects of mercury exposure if the focus of the first of three activities about the properties of metals. Pairs research mercury to write, prepare, and share posters, articles, or PSAs with the class. 

A fifteen-slide presentation helps you teach your young chemists about monomers and polymers. You will find many graphics, some of them colorful, and bullet-point style notes on each slide. Although the presentation is informative,...

Though information-packed, this presentation on soil is drab if it stands alone. As you journey through slides about soil texture, make sure to pass around samples of each type. Perform demonstrations as you lecture on soil density and...

In this colligative properties worksheet, students solve eight problems. They calculate molarity, molality and grams of substances in addition to using colligative properties to calculate solutions.

Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Second graders are introduced to different types of motion. They make rolling spider toys and race them on different surfaces to invsetigate forces and motion. Pupils make glue "spider webs" for their spiders after testing different...

Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Curious physical scientists follow a activity on the properties of water with this activity on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an...

Young scientists create their very own aquifers in this science lesson on ground water. After learning about how some people get their drinking water from underground wells, young learners use sand, modeling clay, and aquarium rocks to...

In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

Here is a nice, clean wrap-up lesson for your chemistry class when they are studying chemical reactions . They experiment with different oils to make soap. To make it more fun, they are to imagine that they are part of a soap testing...

Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Here is a laboratory exercise in which chemistry masters conduct an oxidation reaction to change ethanol into ethanal. They compare the original alcohol to the resulting aldehyde by forming a precipitate. This activity is aimed at...

Students discover how flight is possible.  In this physics lesson, students investigate the properties of a blimp and gyro-copter, comparing rotating wings and fixed wings of aircraft.  Students create their own model aircraft...

Learners discover the properties of light (radiant) energy from the sun by experimenting with solar collectors, cookers, and calculators. After a lecture/demo, students create their own solar collectors and test their efficiency.

What do logarithms have to do with bone density? Scholars learn that the equation for bone density includes logarithms. The majority of the third instructional activity of seven is devoted to logarithms and their properties.

Sixth in a series of 36, this lesson focuses on gases and their behavior in given situations. Learners review the states of matter and then focus on gases, specifically learning Boyle's, Charles's, Avogadro's Laws, Dalton's, and Graham's...
