2017-2018 Science Field Test Overview and Assessment Calendar

3-8 Science Field Test

The Department recently released an update on the LEAP 2025 Science Field Test assessment calendar. “Students in grades 3 through 8 will take a science field test during the regular testing window but will not take an operational science test for the Spring 2018 administration. The items from these field tests will be used to create the new LEAP 2025 science assessments for grades 3 through 8, to be operational with the Spring 2019 administration.

2017-2018 Assessment Calendar

Science and Biology Field Test Item Types

The field tests include the following stimulus-based item types:

• selected-response (multiple choice and multiple select)

• technology-enhanced (dropdown menus, drag and drop, hotspots, etc.)

• fill-in-the-blank

• two-part items made of a combination of item types

o--- two-part dependent, where the score in part B is dependent on the response in part A

o--- two-part independent, where the responses in each part are related in content but not in scoring

• constructed-response

• extended-response

LSU Health Science Center in the Department of Clinical Laboratory Science's CLS program is a Bachelor of Science program in the School of Allied Health that prepares students to take (and pass) a national certification exam upon graduation, which is required to work in clinical laboratories (where your blood gets sent for testing after it’s drawn at the doctor’s office). They accept all prerequisite courses obtained from BPCC, they accept TOPS, and they offer a dual degree program with LSUS where students can obtain a Bachelor of Science in Biology and a Bachelor of Science in Medical Technology at the same time. The CLS program is a great way for students to graduate with a 4-year degree and be immediately employable and earning an actual living wage. It is also a great stepping stone for those who are considering medical school or graduate school.

The first link below is for the homepage, and the second link is a video giving an inside look at a day in the life of a clinical lab scientist. The program will also be featured at the upcoming Caddo and Bossier High School College Fairs.

2017-2018 Youth Wetlands Week Program

The registration for the 2018 Youth Wetlands Week program is now open. This year’s binder will be a revised version of the 2015-2016 “Coastal Louisiana” edition. All of the lessons will be correlated to the standards. Registration is open to any teacher in 3rd – 12th grade; the main subjects featured in this year’s binder are science and social studies. Environmental Science is covered in high school and ELA is covered in upper elementary.

Youth Wetlands Week will be April 23-27, 2018, so please mark your calendars.

Delivery of curriculum and kits is currently scheduled to occur in March. Please forward this information to any and all the teachers in your school that might be interested in receiving this FREE resource. Please complete the registration form (Click Download Documents) and either email or fax it back to Katherine B. Pace by September 29, 2017. Once completed, teachers will be registered to receive the FREE materials in March.

Promoting Student Science Talk in the Classroom

Science learning is fundamentally a social process where individuals engage in making their thinking visible to a group that collaborates to develop, refine, and apply ideas and models to explain and predict natural phenomena. It can be complicated work to develop this kind of collaborative learning culture in the classroom. This playlist is focused on promoting student science talk in the classroom. It presents a set of foundational ideas about promoting learner-centered discourse followed by a broad range of ready-to-go classroom resources to support specific forms of it. Check it out!

Skype A Scientist

Skype a Scientist matches scientists with classrooms around the world! Scientists will skype into the classroom for 30-60 minute Q and A sessions that can cover the scientist’s expertise or what it’s like to be a scientist. We want to give students the opportunity to get to know a “real scientist”, and this program allows us to reach students from all over the world without having to leave the lab! We have over 1700 scientists ready to chat, and teachers can choose the type of scientist that will fit their classroom. Let’s start a conversation!

Cool Phenomena

“Slithering Stones” of Death Valley

At Racetrack Playa in the Death Valley National Park, California, strange forces are at work. Forces capable of pushing heavy rocks across the flat surface of a dried-out lake while no one is looking.

Scientists have scratched their heads over the trails left by these sliding stones since early in the 20th Century. In the 1960s, Californian geologists started a rock monitoring programme.

They tracked 30 stones, weighing up to 25kg, 28 of which moved during a seven-year period – some more than 200m. Analysis of the stones’ trails suggested speeds of 1m per second. In most cases, the stones traveled in winter. In the decades that followed, theories about ice and wind gained support. Others involved algal slime and seismic vibrations.

So what’s happening? Are the stones sliding around in bad weather? ‘We think so,’ says Dr Gunther Kletetschka, of the Academy of Science of the Czech Republic and Charles University in Prague, who led a 2013 study on the stones.

His team’s research describes what happens when water on the Playa surface freezes. According to their theory, ice stuck to the stones remains frozen longer than the surrounding ice – because rock conducts heat away faster. This reduces the force between the rocks and the Playa surface, so they can be pushed by the wind.

Midges swarm over Lake Malawi

Imagine thousands and thousands of flies, all hatching at once in the middle of a huge, open expanse of freshwater...rising up from the lake in huge plumes, like smoke in the distance.

The plumes attract birds and fish, who glut themselves on the insects as they are blown across the lake towards the shores.

Each plume is made up of millions of flies, and as you can see in the image on the right the lake fly make dense clouds that can be seen far on the horizon.

When the lake fly makes landfall, this is the scene close to the shore as they swarm around trees and buildings.

Children go crazy over these lake fly and gather large handfuls of the insects to make into cakes, which they fry and eat!

6-MS-LS2-1: Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.

Lyre Bird

It's safe to say that no bird on earth can rival the viral potency of the Superb Lyrebird. In fact, there aren’t even that many humans who can claim the millions of Youtube views the lyrebird has amassed, thanks to its otherworldly ability to mimic sounds from its environment. Other birdsongs, camera shutters, car alarms, and even chainsaws have found their way into the lyrebird's repertoire.

Science Safety Tips

When Ordering Chemicals for High Schools

Caddo Parish Schools recently completed a monumental chemical cleanup. 100's of bottles of out-dated, corroded, and not used chemicals were removed from high schools to ensure the safety of our students and teachers.

In order to safely remove chemicals from classrooms we must work through the Department of Environmental Equality (DEQ) and the Environmental Protection Agency (EPA) to bring in qualified technicians to log chemicals, properly package chemicals, and safely dispose of chemicals stored in lab closets. This process is exceptionally expensive and time consuming. To limit the amount of unnecessary chemicals Caddo Parish has on hand, I asked your principals to include me in the ordering process for purchasing chemicals for your classroom using classroom fees. Please sent the purchase request to Lisa Nance at or fax to 318-603-6368 to request my signature for chemical purchases. I will send your school a copy of the SDS for each chemical ordered along with a signed copy of the purchase request.
