Welcome to Blake Holsey's first annual pizza party! Attendance by all is required, but Josie, Corrine, Marshall, Lucas, Vaughn, and Professor Z suspect Durst wants to keep them occupied while Victor Pearson initiates a devious plan. Their suspicions are confirmed when they discover a team of scientists outside the school. Josie is amazed when she sees that one of them is her Mom, Kelly Trent. Then, Kelly conducts tests which send Josie into the Wormhole, taking her back in time to three hours earlier! She must inform her Mom about the potential dangers of a fatal discharge of electricity! And she must race against time...

For today's lesson, Professor Z uses a beehive to explain the function of pheromones in the hierarchical structure of a beehive. Meanwhile, cheerleader and super-diva Madison, the most popular girl at Blake Holsey, runs for election without any opposition. After last year's humiliation, Corrine fears entering this year's election competition. Frustrated, Josie decides to run against Madison. In desperation, she makes empty promises. Will she win? Then, Josie and Professor Z discover that Madison is using pheromones to control the students and win their votes...

Marshall is sick, feverish, and to make matters worse he uses all of his spare time working on a new money making scheme. While he feels awful, his new venture, which was doing extremely well and making profits, bottoms out. Bizzarly, even the school develops symptoms of Marshall's infection. Some parts are too cold, others overheat, sneezes and coughs begin occurring from deep inside the school and a greenish slime extrudes from the interior, exactly like Marshall's symptoms. But why does it occur? And when will it stop?

The class studies DNA but one of Lucas' chromosomes gets changed. Becoming more assertive, Lucas gets himself into a lot of trouble, as well as accepting Stew's challenge to a fight.

Lucas and Vaughn get their minds switched and have to experience each other's life. Meanwhile, Josie and Lucas are practicing a scene from Romeo and Juliet for Drama class. To Corrine's surprise, their performance may have been more than acting...

The class chooses elements for their projects on the periodic table. Little does Marshall know he will take on characteristics of several elements as he struggles with the legacy of his brother, who Marshall does not like, when he comes to Blake Holsey for a visit.

There's just no way Josie could be a thief, or could there be? It's a battle of truth vs rumour, as it becomes intolerable for Josie and Corrine to share the same living space. Meanwhile, the sponge in the aquarium is multiplying and covering the school. Lucas, Marshall, and Professor Z have to get to work before the sponges cover the entire planet...

Marshall gets into the cell phone business, but when his business partner, Tyler, wants to use Marshall's special smiley code to cheat on a test, Marshall actually complies. Marshall feels guilty afterwards and Tyler warns him not to tell, but Marshall's new invention turns against him: he can no longer talk understandably. To make matters worse, Professor Z and Principal Durst know Marshall cheated on the test with Tyler...

Practicing for the academic Olympics, Corrine is more critical than usual. Frusterated, the Science Club leaves the room and Corrine finishes the practice equations on her own. When Lucas glows, Vaughn can't stop running, and Josie breaks the laws of gravity, could it be a side effect of the equations assigned to each of them that Corrine did instead? Even if Corrine can undo the work, she still has to face her family's legacy of first prize for the academic Olympics.

You are a math prodigy, a human calculator, and extremely intelligent, however you are not a singer. And that's the last thing Corrine wants to hear from Marshall as she prepares to audition for Magnet 360�. But while looking in the mirror to see whether her fear is obvious to others, the mirror is transformed by BHH energy, and Corrine taken to the other side where she encounters opposite versions of her friends. It's a whole new world for Corrine to discover!

Vaughn gets beaten at an arm wrestling match and Lucas is jealous of the amount of attention Josie pays to Vaughn. But when Lucas and Vaughn gain confidence in themselves after Vaughn wins another arm wrestling match and Lucas beats a rival at chess, could these new health bars play a factor? After the two score very poorly on their midterms and lose self confidence, Josie convinces Professor Z that Lucas and Vaughn need to get a better diet.

Josie gains the ability of echolocation after listening to her music too loudly. She overhears Victor talking from inside Pearadyne2, it is underground beneath her. She and Vaughn investigate what Victor is up to, venturing back into the heart of Victor's invention. The partners in crime appear like they're going to get away with it, but when the alarm goes off and the noise hurts Josie too badly to move, could Victor find out who interrupted his experiment? Wait a minute...what was Victor doing with Josie's missing Chi Gong ball?

BHH curfew is five minutes away and Josie is nowhere to be found. Corrine worries because Josie will break curfew by being late and Lucas is aggravated because Josie forgot that they have a science project to finish. And where exactly is Josie? Her first date with Vaughn! But at the very moment they almost kiss, she hears the BHH curfew bell. And she quickly enters BHH where she runs into Durst as she tries to beat curfew and then discovers that her watch can stop time. Actually, from Josie's point of view, time appears to stop for everyone except her. What happens next? Will Josie be suspended in time forever or rescued just in time?

Just as Vaughn's intelligence seems to be increasing, Josie's intelligence seems to be dropping. Coincidence? Not at Black Hole High...

Josie is having a hard time sleeping at night, but not in class. She has gone cathemaral - she has lost her sleep routine. More worrying, however, are the hallucinations she encounters whilst sleeping...

When Corrine's venus fly trap is left uncovered and alone in the science lab, it becomes a girl. Under the name Diana, she attends several classes at Blake Holsey, and immediately has all the boys competing for her attention. However it is Marshall that she takes a special interest in, which upsets Corrine. The other girls also don't seem too impressed with this new stranger...

Lucas cancels a long-weekend fishing trip with his father so that he can stay at Blake Holsey and investigate Victor and Vaughn. While setting up a surveillance camera in Professor Z's lab, he stumbles upon a secret compartment that holds a strange device. When activated, the device turns the school into a tesseract- causing the school to begin folding in on itself...

When certain members of the school start behaving oddly, it is clear that Tyler is behind it. Could he have gained the power to camouflage himself as others?

A strange occurance in the science lab causes Marshall's phone, a laptop, and Z's camera to shrink to nano size. Intrigued by Tyler's strange behaviour since his discovery of the worm hole, the science club decide to take advantage of the nano-sized camera, and plant it on Tyler. However things become complicated when Josie accidentally swallows the camera.

After continuously losing at hearts, Lucas modifies a new pair of glasses so that he can see through the cards. However things go awry when he becomes able to see through everything. He starts running into things because he can't see they are there. Though, still mistrustful of Vaughn, he decides to investigate his suspicions before seeking help for his impending blindness.

Marshall is testing a rocket but when he launches it, it fails to come down. Instead, a large silver sphere falls from the sky. When the gang go to investigate, the sphere dissolves, leaving behind a strange device. They take it to Z, who also has no idea what it was. When Josie touches it a panel opens up, and a timer begins to count down. Now the science club has 26 minutes to figure out what it does, and what the connection is to Vaughn...

Marshall is busy working on promotions for his band, Magnet 360. He is supposed to write a 1500 word essay for the school paper for his community service, however he runs out of time and ends up filling the space with predictions, thanks to Z's inspiring lesson on horoscopes and The Bell Curve. Unfortunately, he forgets to check his work, and the prediction that 'a member of the science club will diet' becomes 'a member of the science club will die.' It doesn't seem to be a problem until the other predictions start to come true. Now each member of the science club has to work out how to cheat death...

Durst doesn't think Z is being hard enough on his students so decides to take his science class for him to check it out. Josie, knowing Z will go easy on her, cuts class- again. While durst is teaching the class about chirality- mirror opposites- she smells the experiment's resulting liquid and becomes more laid back, just as Z is. Unfortunately the smell also gets to Z, who in turn becomes more strict that Durst ever was. Soon he becomes the acting principal of Blake Holsey, and is giving out detentions for every minor offence. The science club members must figure out how to reverse the effects before Z gets too out of control...

Vaughn tells Corinne that he saw her on the Pearadyne security tapes- talking to his mother. He becomes angry at her when she denies ever seeing his mother. Z explains to the science club about friction- how it can cause things to fuse together. He demonstrates with two blocks of metal. When the lesson is over, Corrine leaves quickly, followed by Vaughn who doesn't believe Corrine is telling the truth about his mother. As the remaining science club members are leaving, they notice that the metal blocks have fused together, despite being set apart. Something clicks and they go to warn Vaughn and Corrine, but it is too late. Vaughn grabs Corrine's wrist to stop her, and suddenly they are fused together and can't separate. Now in order to come unstuck, Vaughn and Corrine must cooperate to find out what really happened when Corrine went through the wormhole.

Josie suddenly finds herself in 1879 by way of the wormhole. Vaughn, Lucas, Corrine, and Marshall come to her rescue. All return to the present except Vaughn, who discovers he has returned to a much different yet familiar reality...
