Making decisions about things like what to do after high school can be a challenge. So many factors are involved. The decision-making worksheet in this resource helps to simplify the process by asking individuals to fill in a matrix for...

Quiz your middle and high schoolers on solving exponential growth and decay. First, they evaluate for a variable given the second variables value. Then, they graph an equation that illustrates the exponential growth or exponential decay...

Tongue Twisters?!  Create scatter plot graphs based on timing fellow classmates saying tongue twisters.  Then investigate, display, and analyze the relationships based on functions.  Wrap up this activity by making a...

Multiplication can be expressed in many ways. This PowerPoint should help students decipher different algebraic expressions by including definitions, examples of word phrases, and placement rules of variables. The last four slides...

Explore the difference between stochastic and deterministic modeling through programming. First have the class write algorithms for relatively simple tasks using pseudocode. Use the Python 2.7 program app to simulate Mendel's Pea Pod...

Return to the classic word problem with these speed scenarios. Learners use some combination of the variables speed, distance, and speed to solve six problems, all of which ask for one of these as an answer. The examples do a nice job of...

My, what big ears you have! Novice JavaScript programmers adjust Mickey's ears to be proportional with his face and any changes to it. The key is to use variable expressions so that the values used are dependent upon the variable that...

Clothing design, do you know any teenagers that are interested in that? How about mixing what they have learned about JavaScript programing and the creativity of designing a piece of clothing? This activity does just that. Practice the...

Combine creativity and coding in an activity where you are free to create your own animal. Try for something recognizable or not, the design is up to your unique students. The challenge is to use variables and variable expressions so...

Resistance is not futile, it is voltage divided by current. A creative simulation presents a wire graphic and allows participants to alter the area, length, and resistivity. As scholars increase or decrease a variable within the...

Is the transfer of energy different in bumper cars with stable versus bouncy bumpers? One of the variables explored in the simulation is bumper type; other variables are the mass and velocity of each car. This allows pupils to see the...

Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...

Touch screens are becoming more common, but how do they work? The simulation shows the electric potential versus system charge as scholars alter three variables. The schematic of the capacitance demonstrates the set up as each variable...

Take a field trip to a location where water and land meet to study patterns of sediment organization in wet habitats: river or ocean beaches, sand dunes, tidal marshes, the edge of a pond, or a woodland stream. Small groups collect pairs...

Provide your class with the opportunity to experience the design process and subtractive sculpture. You mix vermiculite and plaster to create a soft variable material. Learners use this material to carve any abstract art form they...

Producers, consumers, food chains, and plants are the stars of this science lesson. Learners take part in an inquiry which helps them to discover the most effective and efficient way to grow a producer. They have a variety of containers...

A classic investigation on the density of liquids is explained for you in this lesson plan. Te begin, you prepare water samples of different salinities and then add different food coloring to keep them separated and easily identified....

Students observe the effects of eutrophication and determine why it is harmful to aquatic ecosystems. They create mason jar ecosystems to observe the growth of algae in pond water. In addition, they observe the effect of introducing...

In this proportions worksheet, students solve and complete 7 various types of problems. First, they determine the better buy based on the information provided for each word problem. Then, students find the value of a variable given its...

Middle and high schoolers complete and solve 12 various types of problems. First, they express the output as a function of the input in each table. Then, pupils evaluate for the given variable when the value is as stated. In addition,...

In this exponent worksheet, students simplify expressions containing exponents. They use the laws of exponents to multiply and divide positive and negative exponents with variables. This two-page worksheet contains 24 problems. Answers...

Explore economics with this resource on externalities, supply and demand, and third party costs. Learners answer questions, provide examples, analyze and change graphs, and make predictions about the impact of variables.

Teach your learners about the effects of a monopoly on the economy using this resource. Learners examine a graph to answer questions about the impact of variables, and then solve problems using information from the graph.

Does the crystal structure of a hydrated solid determine the proportion of water absorbed, or does the application of heat change the absorption? Scholars experiment with both variables to determine the answer. They add their collected...
