In this must-read fourth book in the Alien in My Pocket series, Zack and his alien friend Amp learn about friction, deceleration, and how to soften a crash-landing in this hilarious new adventure.
When Zack McGee crashes hisbike, he winds up stuck at home with his arm in a sling and his baseball season on the line. Then it gets even worse when Zack realizes the reason why his brakes failed- his four-inch tall alien houseguest, Amp, experimented on them! Now Zack is stuck alone at home, woozy from pain medicine, and unable to do much of anything. All this makes Zack an easy target for his annoying little brother, Taylor, who's determined to find out once and for all what mysteries Zack has hidden in his pocket.
Like every book in the Alien in My Pocket series, On Impact! mixes Common Core-aligned science and safe, hands-on experiments with hilarious stories young readers will love.
