Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

Challenge your classes while developing their problem-solving skills. A square is divided neatly into four equal triangles by its diagonals until one diagonal is moved from a vertex to the midpoint of one side. Now, scholars must devise...

Sometimes losing is actually winning! Learners use a proportional analysis to compare percent weight loss of contestants on The Biggest Loser. The resource provides data and clips from the show to facilitate the lesson.

Pike fish pose a threat to native trout and catfish in lakes. Would you drain and poison a lake to get rid of the Pike fish? If the lake was drained and poisoned, then refilled and repopulated with trout and catfish, how would you...

Learners apply their knowledge of math by rewriting word problems using equations. In this word problem lesson, students build upon previous knowledge as they set up the correct steps to solve word problems. This lesson is full of hints...

Ever wonder how a butcher creates the different types of ground beef? Young mathematicians explore the methods butchers use to create their desired ground beef quality. Given a combination of two types of meat with varying...

Far out — plan a trip to space! Aspiring mathematicians steer a space vehicle through an asteroid field, calculate currency exchanges to buy provisions, and determine placement of charges to blow up asteroids. Along the way, they learn...

Students solve problems dealing with ratios and proportions. In this algebra lesson, students rewrite word problems using equations and symbols. They correctly convert between percents and decimals.

Learners solve problems using equations and properties of integers. For this algebra lesson, students solve problems using ratio and proportion and graph their answers on a coordinate plane. They solve word problems using geometry.

Utilize the lesson on utilization. The second installment of a nine-part technology/engineering series teaches scholars about the flow of a balanced assembly line and the definition of utilization. Videos, activities, and simulations...

Students explain why a transiting planet causes a periodic dimming in the light from its parent star. They determine the radius of a planet, and its orbital distance, by analyzing data and manipulating equations. Students compare the...

Students conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain how...

Does the number of calories you eat affect the total time you sleep? Young mathematicians tackle this question by collecting their own data and making comparisons between others in the class through building scatter plots and regression...

Pupils discover patterns and sequences. They use a website to explore patterns and fractals. Students share their discovery of fractals and their patterns with the class. They develop a list of patterns used in everyday life.
