1 Students play Kahts and cmplete a crsswrd puzzle t reinfrce cntent learning frm their lab n the Galactic Frces f Magnetism, with an emphasis n scientific vcabulary. Grades 3-8 Estimated Time: Minutes Student Outcmes Students will be able t summarize their lab experiences at The Tech. Students will be able t demnstrate their understanding f key vcabulary and cntent regarding planets, electricity, and magnetism. Next Generatin Science Standards Califrnia State Science Standards Mtin and Stability Physical Sciences Grade 4: 1.a, c, d, e, f Grade 3: PS2-4 Cmmn Cre ELA Standards eading Grade 3: 1.6 Grade 4: 1.6 Grade 6: 1.3 Grade 7:1.2 Grade 8: 1.3 Writing Grade 3: 1.1 Grade 4: 1.1 Listening & Speaking Grade 3: 1.2, 1.7 Grade 4: 1.4 Grade 7: 1.5 Writing Strategies: Grade 7: 1.2 Vcabulary Familiarity with these terms and cncepts will enhance students experience in the activity. Alpha Magnetic Spectrmeter: Lcated n the Internatinal Space Statin, this particle detectr is helping scientists measure anti-matter. Attract: Oppsite ples f tw magnets attract each ther. Aurra Australis: Als called the Suthern Lights Aurra Brealis: Als called the Nrthern Lights Circuit: The cmplete path that allws the flw f electrical current. Cmpass: A navigatin instrument that uses magnets. Cre: In this layer f the Earth yu will find mlten irn and nickel Crnal Flares : A brightness at the surface f the sun caused by ejectin f ins, electrns, and atms. Earphnes: Listening t music is easy with this device that uses electrmagnets Earth: The planet we live n is Earth. Electricity: The mtin f charged atmic particles called electrns. Electrmagnet: A type f magnet in which the magnetic field is prduced by electrical current flwing thrugh a cnductr. Electrn: An elementary particle having a negative charge, fund utside the nucleus f an atm. Field: An invisible field prduced by magnetic bjects r electrical current. This is called a magnetic field. Frce: A push r pull that causes a change in the mtin f a mvable bject, r puts stress n an unmvable bject. Maglev: A type f train made pssible by electrmagnets Magnet: An bject cmpsed f magnetic material that is able t prduce its wn magnetic field. Magnetic Ples: The tw ends f a magnet where the magnetic field is cncentrated. Mars: The red planet named because the irn xide n the surface gives it a red hue. epel: The nrth ples f tw magnets repel each ther. Shrt Circuit: A path in the circuit that has n element between tw different vltage ptentials. Slar System: This system is cmprised f the sun and all bjects that rbit it. Slar Winds: These cluds f high energy particles stream ff the sun s surface in all directins. Venus: The secnd planet frm the sun.

2 Materials (ne set per grup f 4 students) Fr Kahts: Cell phnes/tablets/cmputers (per student r fr grups f students) A display screen with internet cnnectivity Cmputer fr the teacher t run Kahts Cpies f Crsswrd puzzle fr teams r individual students Pencils r pens Paper r jurnals Teaching pints: 1. Think-Pair-Share n what students remember f their field trip t The Tech Museum. a. Have students spend tw minutes thinking abut their trip t The Tech r jurnaling abut their experience. b. Then have them spend tw minutes sharing their memries with their desk neighbrs. c. Finally, have students share their thughts with the class. 2. When we are learning new ideas it is imprtant t practice and reflect n ur new learning. Why d yu think this is the case? Pssible Answers: S we dn t frget, t make the memries strnger, r t use the infrmatin in new r different ways. 3. Tday we are ging t play tw games t practice the vcabulary we have been learning. Prcedure: 4. First students play a 20 questin Kahts quiz using this link t review sme vcabulary-based cntent frm the lab. This can als be a gd pprtunity fr the teacher t assess if any cntent needs t be retaught. a. Kahts is a free game platfrm which wrks best in grup settings. If yu haven t used it befre, it is like an electrnic trivia game night that can be created r custmized by anyne. A teacher can display the game frm their cmputer thrugh a prjectr. Then students can play individually r in grups using mbile devices (phnes r laptps). T learn mre abut Kahts visit their website r read mre here: b. The Kaht prvided fr this activity uses images and multiple chice questins t help students learn r reinfrce learning with graphic and verbal representatins in a lw risk envirnment f a game. 5. Next give students the crsswrd puzzle n the furth page f this lessn plan. A wrd bank has been included at the bttm f the crsswrd puzzle as an additinal scaffld. Many f the wrds and clues were included in the Kahts and cvered in their Galactic Frces f Magnetism lab. 6. G ver the answers f the crsswrd 7. (Optinal) Several f the wrds have etymlgical rigins that culd be useful acrss multiple languages r help scaffld future scientific vcabulary develpment. Belw are 6 wrds, their etymlgical rigins, and interesting trivia that yu may wish t share with yur class. : a. Circuit - Latin circuitus meaning g arund. A clsed circuit allws electrns t travel in a circular pattern. b. Cmpass Latin cm- meaning tgether + passus a step r pace c. Crnal Latin crna meaning crwn d. Slar Latin sl meaning sun e. Electric Greek elecktrn r Latin electrum meaning amber. Why amber? Here is a 3 minute vide that gives a very brief histry f electricity, including hw amber can be used t create what we nw call static electricity : f. Magnet - Greek magnes liths meaning Magnesian stne r Latin magnetum meaning ldestne r waystne

3 Magnesia is in the Thessaly regin f Greece where naturally ccurring magnetically plarized xide f irn was discvered by the Ancient Greeks. The wrd ldestne frm Latin meant that these naturally ccurring rcks were used t help navigate, like a cmpass. The navigatin use f ldestne appears t have been used by bth the Ancient mans and Chinese. Yu can read mre here: Teaching Pints: 8. Tday yu have dne a great jb at summarizing what yu learned at The Tech Museum and demnstrating yur understanding f vcabulary and cntent. Gd wrk! Taking it Further Have students identify ther wrds with the Latin and Greek rts and create a pster shwing what they have in cmmn. Have students create experiments using magnets. Cnsider designing an experiment n factrs that affect the strength f magnetic fields. Have students create their wn Kaht games t demnstrate their learning frm their field trip r in their current science unit.
