Which sports drink provides the best pick-me-up after the big game or grueling workout? It may not be the one you'd think! Food science is the focus in a surprising lab activity. Pupils use colorimetry to determine the amount of protein,...

Can your biology class crack the Case of the Crown Jewels? Junior forensics experts try their hands at DNA restriction analysis in an exciting lab activity. The lesson introduces the concept of restriction analysis, teaches pipetting and...

Transform your class' understanding of genes and antibiotic resistance with the Transformation Lab. Junior geneticists create and observe their own resistant strains of E. coli through research, discussion, and experimentation. The...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Can turning on the television lead to toxins in the food supply? The lesson offers an opportunity for young scientists to complete guided research. A worksheet lists each question as well as the web page necessary to answer the question....

PolarTREC brings polar researchers and educators together to benefit both science and education. Pupils select one research project in Antarctica to explore and present to their peers. Scholars polish research and presentation skills as...

Would you want to vacation in the Arctic or Antarctic regions? Scholars research both regions and produce a travel brochure trying to convince tourists to visit. The project focuses on the geography, climate, flora, fauna, and indigenous...

The Kuril islands stretch from Japan to Russia, and the ongoing dispute about their jurisdiction prevents many scientific research studies. Scholars learn to create a topographic profile of a specific area around their schools. Then they...

Reinforce properties while solving equations. Learners often ignore properties even as they try to apply them. A well-designed lesson emphasizes the role of additive inverses when solving equations.

What's the rule that makes it true?  A virtual function machine generates output values as learners submit the input values. Their job is to analyze the inputs and outputs for a pattern and write a function rule.

Challenge your classes to find the pattern of a double function machine. After recording the outputs of both machines, learners identify the pattern and the corresponding function. Both patterns involve adding/subtracting a constant.

Watch as a function machine converts an input to an output. Learners determine the work applied by the function machine to write a function rule. Questions accompany the function machine animation to guide individuals to conclusions.

This is the ticket to learning about function rules! Using online manipulatives, scholars build a table of values and then answer questions about the related function. They examine the relationship between the input and output values and...

Examine the relationship between the input and output variables in a table of values. As learners build an input-output table using online manipulatives, they begin to identify patterns. They answer questions about these patterns...

Investigate division within an algebraic term using an inquiry-based lesson. Individuals adjust sliders and watch as the simplification of the term changes. Questions help guide them to important conclusions.

Model expression division using online manipulatives. Learners drag C's representing a term into equal groups. Guiding questions help them see their groups as the division of the term.

Investigate the process of combining like terms using an interactive animation. Scholars tackle simplifying expressions by manipulating rectangles that represent the terms. They add and subtract terms to arrive at the result.

Discover how the distributive property applies to division. As learners change numeric values within an expression, the simulation calculates its value. Challenge questions lead individuals to realize the power of distributing the...

Model the distributive property with jars of fireflies! An interactive animation has learners manipulate the number of jars of fireflies to determine the number caught. Accompanying questions ask scholars to consider the multiplication...

A remotely operated vehicle approaching a volcano was engulfed by molten sulfur where the plumes of fluids contained the highest concentrations of aluminum ever recorded. This isn't science fiction or an April fools joke, though it did...

Scientists can model global surface temperature with and without considering human emissions, but does do these factors really make a difference? Two interactive graphs demonstrate some factors that affect climate change. The first graph...

What happens to stars as they get older? A simulation takes pupils through the life cycle of stars based on their masses. The resource introduces the Hertzsprung-Russell diagram and the common relationships and life cycle patterns observed.

Tree rings are slightly thicker on the south side of the tree because it receives more sunlight. Part two in a series of five lessons helps learners analyze tree rings to determine the environmental conditions that caused size...

The climate change debate, in the political arena, is currently a hot topic! Learners explore carbon dioxide levels in our atmosphere and what this means for the future in the 11th installment of 12. Through an analysis of carbon dioxide...
