In this unit, students will learn how to measure the quantity of heat. Lessons in this unit include: What Does Heat Do?; Measuring the Quantity of Heat; and Calorimeters and Calorimetry. This unit includes videos, animations, and mini quizzes to check for understanding and facilitate learning.
In this unit students will learn about thermal energy, heat, and temperature. Lessons in this unit include: Introduction; Temperature and Thermometers; Thermometers as Speedometers; What is Heat?; Methods of Heat Transfer; and Rates of Heat Transfer. This unit includes videos, animations, and mini quizzes to check for understanding and facilitate learning.
In this STEM activity, students are challenged to solve a real-world problem that is part of the space program while learning about heat and heat transfer. Students will observe a design before and after testing, and pick out the-key features as they apply the design process to a problem. In the challenge, students will build a structure from aluminum foil and copper screening that will protect a model of the Ares launch vehicles from the heat of a propane torch for as long as possible. Students will document their designs with sketches and written descriptions. As a culmination students compile their results into a poster and present them to the class.
The Solar System unit is a third grade science unit. It focuses on the sun's daily and annual pattern, the moon's cycle and the sun and the stars.
In this activity, students interpret the landscape using topographic maps of well-known national parks.
GeoInquiries are designed to be fast and easy-to-use instructional resources that incorporate advanced web mapping technology. Each 15-minute activity in a collection is intended to be presented by the instructor from a single computer/projector classroom arrangement. No installation, fees, or logins are necessary to use these materials and software.
In this activity, students will calculate the amount of heat gained by water and lost by a metal during a simple lab experiment. This activity can be easily modified so students are tasked with identification of an unknown metal instead.
In this lab activity, students will be asked to observe and then test the properties of several different elements. In their observations they will be looking for the physical state, whether it is shiny or dull, and whether it appears malleable or brittle. For some of the elements they will also test the conductivity, malleability, and reactivity with dilute acid. From their data, they classify each element as a metal, a non-metal or a metalloid. Results will be color coded on a periodic table (e.g. Blue for metals, yellow for non-metals, and green for metalloids). They will use this to determine trends for metallic properties of the elements.
In this lesson, students conduct four different experiments, each of which can be classified as one of the four basic types of chemical reactions.
This video lesson reviews the four main types of chemical reactions by describing each one, providing an example of each, and giving students opportunity to practice identification.
This presentation is in Google sheets form and allows students to demonstrate their knowledge of clouds.
This applet simulates two runners moving along a track and creates a graph of the time-versus-distance relationship of their motion. Students then observe the simulated races as they happen and relate the changing positions of the two runners to dynamic representations that change as the events occur. Students can predict the effects on the graph of changing the starting position or the length of the stride of either runner. They can observe and analyze how a change in one variable, such as length of stride, relates to a change in speed. This computer simulation uses a familiar context that students understand from daily life, and the technology allows them to analyze the relationships in this context deeply because of the ease of manipulating the environment and observing the changes that occur.
In this activity, students will understand the concept of half-life and how it relates to radioactive material. Students will determine, with a simulation activity, the half-life of a radioactive element, "Coinheadsium". Students will create and be able to recognize a graph representing the half-life of a radioactive element.
This lesson will help students grasp the relationships among protons and electrons, locations of various elements, electron energy levels, and oxidation numbers. Students will draw and analyze electron energy level diagrams and then determine the oxidation number based on their diagrams.
Students will investigate constructive and destructive interference by observing the light patterns on the surface of soap bubbles.
Students will observe a solubility test between salt and sugar. They will then be presented with 4 known crystals and an unknown. Based on the solubility demonstration, the class will design a solubility test to discover the identity of the unknown.
In this activity, students will be provided a blank periodic table and will fill in the electron-dot model for the first twenty elements. This will help students see the relationship between numbers of valence electrons and properties of elements.
Students will learn about the position of the sun and moon in the sky to develop an understanding of relative distances, the appearance of movement across the sky, and relate it to day and night, Earth's orbit, the spin of the Earth, and the visible shape of the moon.
This assessment checks student understanding of how gravitational force affects the velocity of an object in freefall.
Students explore the effects of gravity on objects of different masses during free fall.
In this interactive lesson, students explore the effects of gravity on objects of different masses during free fall.
