First graders study and describe simple machines such as the hammer, screwdriver, nutcracker, bottle opener and scissors and select the appropriate tool for a particular type of work.

Students use the reaction time to figure out problems. They use the following example to get them started with reaction time: the edge of a ruler is placed near a person's thumb and index finger and, without warning, the ruler is...

Pupils create a model of the distances of the planets in the solar system using sheets of toilet paper and markers. Generally accepted orbital parameters are applied.

In this problem solving worksheet, students complete 10 problems about speed, distance, time, measurement, and more. There are no answers provided.

Pupils explore the concept of coordinate proofs. For this coordinate proofs lesson, students write coordinate proofs using properties of distance, slope, and midpoint. Pupils discuss why it is sometimes beneficial to double the...

In this heat transfer activity, students observe photographs of the various ways heat is transferred. Included is a radiator giving off heat that rises and cools as it settles, the sun radiating heat to the earth and a house absorbing heat.

In this measurement worksheet, students measure distance with a provided ruler. Using the provided map scale, students determine the actual distance between objects. They may set up proportions to evaluate each situation.

Learners use a model to determine the distance between the sun and plants in our solar system. They determine a scale to use that represents the distance between the Earth and sun. Students calculate the scale distance that each planet...

Students apply what they recall about objects in motion by animati ng sequences of pictures that model a set of physical conditions. They animate the orbital motions of the Earth, the space shuttle, and the Moon based on calculations of...

Fifth graders investigate how to find the average and the concept of a per unit quantity and its applications. They also make connections of using population density and how to find the speed with its relating formula. This is bringing...

Learners plan a voyage as the captain of a tall ship in the early days of exploration and merchant trading. They choose 2 ships and 3 voyages for a total of 6 possibilities. They calculate the number of days and distance of their...

Learners are introduced to the the formula for calculating travel time. They listen to different scenarios relating to long distance travel into space and calculate travel time using the formula.
