Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a lesson on...

Discover how to program objects to move on a screen. In the second lab of a five-part unit, each learner uses block instructions to program a sprite to follow their mouse (cursor). They investigate how to use these same block...

Students study the importance of preserving the archaeological record. They write a paragraph describing an object and why it is important to them. They cut their paper into a puzzle and compare their own to the student they trade with.

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

Fourth graders conduct an experiment related to heat sources, and participate in a heat source hunt. They identify sources of heat, then compare the melting rate of ice cubes, illustrating the results in their science journal. Students...

Third graders explore the structural composition of buildings and houses. In this math lesson, 3rd graders explain how architecture is related to mathematics. They create a blueprint of a structure with at least three different spaces.

Learners participate in a number of hands-on shape-related activities. They match and sort shapes by attribute, read books about shapes, complete shape art projects and explore and compare parts of shapes.

Pattern recognition is a skill often used in mathematics. Learners count and sort manipulatives, organize the data into a graph and answer questions about the information displayed. They collect the objects to be used and create patterns...

Students investigate the concept of perimeter. They design there own figure and measure the perimeter of it. The lesson plan is given the context of the shape being a path that is traveled by a ladybug. This provides the shape of the...

Examine patterns of figures composed of six-squares and predict which of the twenty presented could be folded to make a cube. They then fold large-scale patterns of these figures to confirm their hunches.

The lesson focuses on the ideas of dot plot representations and the mean absolute deviation of data sets.

Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a...

Pupils use a variety of sizes of class poster groundhogs to order the objects by size. The groundhogs are replaced by a bag of objects and the sizing exercise continues.

Students paricipate in seven activities to investigate ancient stories about heroes, monsters, gods, and goddesses.

Students recognize the symbol for and demonstrate the rules of set.

Students make a math book. In this early childhood math lesson plan, students develop language, observation, and math skills as they explore the sizes of objects and use cameras to take pictures for their own math booklet based on...

The mean might not always be the best representation of the average. The assessment task has individuals determine the measures of center for the salaries of a company. They determine which of the three would be the best representation...

Knowledge of statistics and probability can increase your advantage when playing games. The activity asks learners to analyze the game of MasterMind to determine the number of possible codes. They also examine different variations of the...

The class gets their mean and median all in a row with an assessment task that uses a population of ducklings to work with data displays and measures of central tendency. Pupils create a frequency chart and calculate the mean and median....

Have you ever looked up at the night sky and wondered what constellation you were seeing or whether that bright object was a star or a planet? Are you searching for the best tilt-to-view constellation and planet app that money can't buy?...

Which pulley system will give us a whale of a good time? Teams compare the theoretical and actual mechanical advantages of different pulley systems. They then form a recommendation for how to move a whale from an aquarium back to the ocean.

Ground-truthing ... is it even a word? The last installment of a five-part series analyzes how scientists collect sea surface temperature data. Scholars use government websites to compare temperature data collected directly from buoys...

Class members will dig this activity that has them trying their hand at recovering artifacts. Groups are assigned a section of a sandbox, carefully uncover the artifacts in their section, and then develop theories about who might...
