In this well-developed lesson plan, students will develop a model of a wind turbine and present their models to the group. The students will further construct an explanation of the design to support that energy is transferred and...

For this fourth grade performance assessment task, students sort candies according to their properties and demonstrate their understanding of binary classification principles.

Liking to eat is not a necessary requirement for a food science technician, but liking to work in a laboratory is. Find out the range of jobs a food science technician might perform in assessing food quality. Science Buddies offers a...

This performance task assesses students' ability to use a balance and to measure the mass of objects accurately.

Students will observe water evaporation in this performance task, and investigate the water cycle. The task is designed for Grade Two.

This performance task tests students' ability to measure length, volume and temperature accurately in a lab setting.

As they examine two variations of a can opener, students will discuss what the purpose is of each of its sub-parts, and which of the can openers is the better machine. They will also suggest improvements to the can opener. This is a...

For this fourth grade performance task, students measure tree leaves using metric units and make predictions about the length of other leaves on the tree. They also suggest other good questions they might ask about trees in the school...

For this Grade Two performance task, students observe the contents of a terrarium and explain the purpose of the water, rocks and soil inside it.

This is a performance task for Grade Four students where they observe two different pendulums and compare the two types of motion. The activity is designed for a lab setting where students work at individual stations. A rubric and...

This is a performance task where students sort and classify rocks based on their properties, then demonstrate how they can transfer their understanding to decide on ways they might sort and classify other types of objects.

Here you can find what you need to scientifically assess battery performance. In this exercise (that should take about one week) learn how batteries work, how they wear out and most importantly, how to make valid measurements to assess...

This activity has students sort garbage, graph their results and propose ways of reducing waste.

A unique approach to determining size and weight of an object through water displacement: students are presented with a scenario along with a variety of balls made of different materials and pitchers of water. Working in small groups,...

Straightforward introduction to electrical circuits using minimal materials and time. Students learn about the basics of electrical circuits by experimenting with "mystery cards" -- index cards with hidden aluminum foil used to conduct...

Students make predictions and test the effect water has on various building materials. Seven different building materials, a hand lens and a dropper are required. This activity only takes 15 minutes.

Students are given some guidelines to develop experiments to see how slugs or earthworms repsond to stimuli such as vinegar and light. This activity is designed to last 4 class periods.

This activity directs students to set up a two step classification scheme based on the physical traits of color and shape.

This lab incorporates observational skills to solve the problem of finding the best rock to build tables for a museum picnic area. Students are called on to observe the properties of the rock samples and then required to apply what they...

This lesson plan requires students to make an inference (hypothesis) about two animals based on the tracks they leave behind. Students are asked to write a story explaining their inference.

Students use a 10 step dichotomous key to identify three mythical animals of their choice. The pictures of the animals and the key are both provided.

A lesson plan for guiding students through a simple research experiment focused on transfer of energy is described for teacher administration and student explanation. Also includes a detailed rubric for evaluating student work.

Students test their observation skills as they make predictions about the objects that are in three different boxes.

The Nation's Report Card, the National Assessment of Educational Progress (NAEP), is the only nationally representative and continuing assessment of what America's students know and can do in various subject areas. Since 1969,...
