Pupils explore the concept of trapezoids.  In this trapezoids instructional activity, students identify legs and bases of a trapezoid.  Pupils discuss the similarities and differences between isosceles trapezoids and right...

Students use comparisons, graphing, patterning, and sorting, and develop language skills as they explore the five senses.

Learners measure water and make predictions about efficiency.

Students investigate the concepts that are related to finance and how it is used in the world. They take part in activities that are focused around the use of a spreadsheet while using a T-chart to simulate a ledger of credits and debits.

Students examine how multiples of the denominator indicate that a fraction can be renamed as a whole number, and convert improper fractions to mixed numbers. Independently they read examples, and complete a variety of problems on a...

Students use rounding and compensating with whole numbers and explain how to use the empty number line to show additions and subtractions. They round and compensate in relation to decimal subtraction Background

Students use fractions strips to demonstrate addition and subtraction of fractions. They explore finding common denominations, examining equivalent fractions, and simplifying fractions. Students may work in groups or independently.

Learners explore the concept of solving two-step equations. In this solving two-step equations lesson, students watch a short video about solving equations. Learners view a PowerPoint presentation about solving two-step equations....

Students explore the concept of transformations.  For this transformation lesson, students use an applet that is an interactive absolute value graph applet.  Students manipulate the applet to examine the change in the function...

Students explore the concept of multi-step equations. In the multi-step equation lesson, students solve equations by the 'party method'. Students make a flip book that shows the steps in solving multi-step equations.

Young scholars explore ratios and their relationships to fractions. They explain the process of identifying ratios and describe their comparison. Students write ratios as fractions and by using colons. They convert the ratios to...

Fifth graders practice using estimation. In this estimation lesson, 5th graders add, subtract, multiple, and divide using whole numbers, fractions, and decimals. Students decide upon instances when estimation is more appropriate than...

Students investigate how to denature proteins. For this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to denature...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups...

After learning about P waves and S waves, fifth graders view the intensity of earthquakes by examining seismographs and images of earthquake damage. Young scientists then forecasting future quakes by analyzing data about...

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Class members create their own social networks by collecting signatures before graphing the interactions with their fellow classmates. The degree distribution of the simulated social network is determined by calculating the degree of...

What effect makes children's shoes light up? Answer: Piezoelectric effect. Here is a PowerPoint presentation that describes piezoelectric materials as being able to convert mechanical energy to electrical energy. Individuals learn how...

Students read about and discuss how chemical engineers use different states of matter to create substances. In this chemical engineering lesson plan, students also give examples of the 3 kinds of matter.

Students examine bone fractures and the role that engineers play in repairing them.  In this biomedical engineering lesson students describe the factors that engineers consider when designing devices. 

Students conduct an experiment. In this water lesson, students watch the lesson "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their items. Students discuss their...

Students induce an electrical charge on various objects, and experiment with electrical repulsion and attraction. They define related vocabulary, play Bingo and complete a take-home quiz.
