A fact is something which is true, which can be proven. An opinion is a belief and can't be proven.

Decide whether each sentence is fact or opinion.

Based on what they have already learned about friction, students formulate hypotheses concerning the effects of weight and contact area on the amount of friction between two surfaces. In the Associated Activities (Does Weight Matter? and Does Area Matter?), students design and conduct simple experiments to test their hypotheses, using procedures similar to those used in the previous lesson (Discovering Friction). An analysis of their data will reveal the importance of weight to normal friction (the friction that occurs as a result of surface roughness) and the importance of surface area to the friction that occurs between smooth surfaces due to molecular attraction. Based on their data, students will also be able to calculate coefficients of friction for the materials tested, and compare these to published values for various materials.

This short video and interactive assessment activity is designed to teach fourth graders about completing the number patterns based on the multiplication table.

This problem uses the same numbers and asks essentially the same mathematical questions as "6.NS Bake Sale," but that task requires students to apply the concepts of factors and common factors in a context.

Students will begin to understand the concept of maps by describing the path that Little Red Riding Hood took on the way to Grandma's house. Main Curriculum Tie: Social Studies - Kindergarten, Standard 3 Objective 1, Identify geographic terms that describe their surroundings. Many fairy tales and nursery rhymes take the characters on a path through the rhyme/story. In this lesson, we will be making up maps for the characters to follow. In the first activity, the class will be recreating a map of the path that Little Red Riding Hood takes to Grandma’s house. The students will be exploring basic map directions and characteristics.

Picture books provide the basis for an analysis of fairy tale elements before students write their own original tales.

Inspirée du livre de Lynette Comissiong, ce court métrage d’animation est en quelque sorte une version caraïbéenne du conte Hansel et Gretel. Sourds aux avertissements de leur mère, Tina et Dalby traversent le pont interdit et se retrouvent prisonniers de la méchante Mama Zi, une cocoya (esprit maléfique). Ils se croient perdus mais Tina, qui est très futée, convainc Mama Zi de continuer à se prélasser au soleil, ce qui donne aux enfants le temps de s'enfuir.

Using an Arduino microprocessor, students will build an automated fish food feeder so fish can be fed when no one is at school?

This project involves learning how to do simple wiring of an LED, a buzzer, and a servo (motor) to a simple-to-use Arduino microprocessor.

Students drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. They follow good experiment protocol, take measurements, calculate averages and graph results. In seeing how falling water can be used to do work, they also learn how this energy transformation figures into the engineering design and construction of hydroelectric power plants, dams and reservoirs.

This activity shows how an ordinary ruler can measure human reaction time (RT). Learners will convert a standard ruler into a time ruler (relating time and distance) and measure each others RT. They will also calculate means and variances and the RT required to accomplish a specific task. Additional resources and an extension to this activity are available. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This is a collection of tools to assess the effectiveness of family engagement in a school's learning community.

Family History Inquiry Project in action.

In this Grade 1 inquiry project, the students compare past and present. They make personal connections and are engaged in the process of finding out what life really was like in the past, as well as find similarities to their own lives. Through the use of technology, iPod Nanos and mini-camcorders, students will not bogged down by their limited writing abilities. For English language learners, the use of technology permits them to gather stories in their families' native language.

After reading a short memoir and reviewing the genre, students choose how to create a memoir of a family member who is at least a generation older. Students first select a family member to interview, and then craft a set of interview. Students create written memoirs, focusing on one or two unifying themes, and can be presented as a photographic collage, a series of panels telling a story, a painting, a video, a musical composition, a sculpture, or another creative way. Students accompany their work with an artist̍s journal, explaining why they have chosen the particular method of presentation and analyzing their own successes and shortcomings.
