Science 7

  • WEEK OF MAY 15

    Monday, May 15:  Finish Activity 81, Do Activity 82 Braking Distance

    Students measure the braking distance of carts by releasing them onto a track with a high-friction surface. They compare the braking distance of the cart at different initial speeds and find a relationship between the initial speed of the cart and its braking distance.

    Tuesday, May 16:  Activity 83 Coming to a Stop

    Students learn that the distance a car takes to stop is a result of two separate events—the distance traveled during the driver’s reaction time and the distance traveled once the brakes have been engaged, both of which increase with increased speed. They investigate the actual stopping distance of cars by calculating and graphing data for different speeds, road conditions, and states of driver alertness.

    Wednesday, May 17:  Finish Activity 83

    Thursday, May 18:  Activity 86 Investigating Center of Mass

    Students are introduced to the concept of center of mass. They observe empty and loaded carts hitting a barrier and compare the stability of vehicles with different masses and centers of mass. They apply their results to vehicle design and rollover accidents.

    Friday, May 19:  

    WEEK OF MAY 8

    Monday, May 8: Activity 79 Inertia Around a Curve

    Students investigate inertia by making observations of a marble’s motion around a circular track. They predict and then observe the direction the marble rolls when a section of the track is removed and the marble moves due to its inertia. They also investigate whether changing the mass of the marble affects the motion of the marble.

    Tuesday, May 9:  Activity 80 Newton's Laws of Motion

    Students complete a reading about forces and Newton’s three laws of motion. The reading is supported by a literacy strategy designed to reveal and address common misconceptions about force and motion. A second literacy strategy supports comprehension during the reading. Students then discuss aspects of Newton’s laws that seem to contradict daily experience.

    Thursday, April 27: Activity 76 Speed and Collisions

    Students investigate the effect of speed on the severity of a collision. Using different release heights, students compare how far a block placed on the track moves after it has been struck by a cart. Students discover that a faster-moving cart moves the block
    farther. Assuming that the time of impact is about the same, the data indicates that the faster the cart is moving, the greater the force on the block. This conclusion is applied to the situation of car collisions.

    Wednesday, February 8: Finish Activity 54, Start Activity 55 Plants Have Genes, Too!

    Students germinate seeds that are the offspring of plants bred from true-breeding green and plae yellow strains of a flowering garden plant.  By predicting and then quantifying the colors of the offspring plants, students obtain genetic data for analysis.

    Thursday, February 9:  Continue Activity 55, Start Activity 56 Joe's Dilemma

    Students are introduced to the issue of genetic testing through a story about a student who suspects he may have inherited a genetic syndrome (the Marfan syndrome).  They generate questions they would have if they were in this situation, and make a
    preliminary decision of what they would do based on the limited information they have so far. Students then view a video produced by the National Marfan Foundation to find outmore. They consider the impact of the Marfan syndrome on a person’s life.  Activity 67, “What Would You Do?” will follow up on this activity, enabling students to make a recommendation to Joe after they have learned more about genetics.

    Monday January 23: Activity 60:  Changing States of Matter

    Students are introduced to the different forms of water and how they change from one to another. The class discusses the relationship between the changing states of water and the water cycle.

    Tuesday, January 24:  Continue Activity 60

    Wednesday, January 25:  Finish Activity 60, Analysis Questions

    Thursday, January 26:  Activity 62 The Water Cycle

    Water Cycle diagram (detailed) and questions

    Friday, January 27:  Activity 64 Earth's Atmosphere

    Students use a computer simulation to sample air composition, temperature, and pressure at different altitudes above the earth’s surface. They take three samples within each atmospheric layer and calculate the average values. They then compare the properties of the different atmospheric layers.

     

    WEEK OF JANUARY 16

    Monday January 16: No School

    Tuesday, January 17:  Finish Activity 56

    Wednesday, January 18: Presentation by Mr. Wilcoxson from CHS

    Thursday, January 19:  Activity 57: Oceans and Climate

    Students learn more about how oceans affect climate. They participate in a role-play that discusses the history of the identification of the Gulf Stream and how modern technology is used to gather ocean data.

    Friday, January 20:  Activity 58: The Causes of Climate

    Students read about more factors affecting climate, including the sun’s energy.

     

    WEEK OF JANUARY 9

    Monday January 9: Finished Activity 69 

    Presented weather reports and Analysis Questions

    Tuesday, January 10:  Activity 55: Heating Earth's Surface

    Students perform an experiment to measure how the Sun’s energy heats land and water as well as how quickly both of those substances cool. 

    Wednesday, January 11:  Perform Activity 55 investigation

    Thursday, January 12:  Finish Activity 55, start Activity 53 Weather and Climate

    Students use a literacy strategy to organize the information about different climates (dry, tropical, etc.). They identify their local climate and compare their personal observations and seasonal weather averages to the climate description. Students then examine climate graphs for three different regions and use the graphs to identify each region’s climate. The class discusses the relationship between climate and weather. 

    Friday, January 13:  Finish Activity 53 and start Activity 56 Ocean Temperatures

    Students investigate the range of mean ocean surface temperatures around the globe. They map and discuss patterns of surface temperatures in particular regions of the oceans. The members of each small group then merge their findings and summarize
    global patterns. They use this data to further investigate climate patterns on earth.

     

    WEEK OF JANUARY 2

    Monday January 2: No School

    Tuesday, January 3:  Start new unit: Weather and Atmosphere, Activity 51: Investigating Local Weather

    Students record and analyze five days of daily weather data. They then record and graph local monthly weather averages. They compare daily weather conditions to the monthly weather data.

    Wednesday, January 4:  Finish Activity 51, Start Activity 69: Forecasting Weather

    Students work together to interpret a weather map and construct a weather report. Each group then presents a weather report to the class. Students use this information to forecast the next day’s weather.
