This task is related to Sub Claim C: Elapsed Time. Students are adding and subtracting time intervals on a number line. Standard 3.MD.1
In this activity, students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas produced from a chemical reaction between an antacid tablet and water to propel it. Students observe the effect that surface area of this simulated solid rocket fuel has on thrust.
Students use balloons to perform several simple experiments to explore static electricity and charge polarization.
In this Cyberchase video segment, Matt uses subtraction to help Digit figure out how much time he has left in a cooking contest with Hacker.
The CyberSquad must construct a clock of sorts in order to keep track of the amount of time they have to rescue Dr. Marbles in this video segment from Cyberchase.
Harry estimates how long it will take him to get to the front of a long ticket line in this Cyberchase video segment.
In this video segment from Cyberchase, through addition and regrouping in base sixty, Matt helps Digit figure out what time his CyberSoufflŰ__ŰÖ will be done.
Module 2 uses place value to unify measurement, rounding skills, and the standard algorithms for addition and subtraction. The module begins with plenty of hands-on experience using a variety of tools to build practical measurement skills and conceptual understanding of metric and time units. Estimation naturally surfaces through application; this transitions students into rounding. In the modules final topics students round to assess whether or not their solutions to problems solved using the standard algorithms are reasonable.
In this video segment from TV411, WNBA player Olympia Scott Richardson discusses her techniques for effective time management.
That heat flows from hot to cold is an unavoidable truth of life. People have put a lot of effort into stopping this natural physical behavior, however all they have been able to do is slow the process. Student teams investigate the properties of insulators in their attempts to keep cups of water from freezing, and once frozen, to keep them from melting.
In this activity, students discuss the notion of time and how time can be measured. They build an hourglass to measure time and test it. This activity will allow students to have a better understanding of time and the instruments that can be used to measure it.
