Questions about the Energy in Reactions poster

What’s on the Energy in Reactions poster?

EXOTHERMIC against ENDOTHERMIC, side by side. EXOTHERMIC: Releases energy to the surroundings; EXOTHERMIC: Temperature of surroundings rises; EXOTHERMIC: Bond making releases more than breaking absorbs; EXOTHERMIC: Combustion, respiration, neutralisation; EXOTHERMIC: Products have less energy than reactants; ENDOTHERMIC: Absorbs energy from the surroundings; ENDOTHERMIC: Temperature of surroundings falls; ENDOTHERMIC: Bond breaking absorbs more than making releases; ENDOTHERMIC: Photosynthesis, thermal decomposition; ENDOTHERMIC: Products have more energy than reactants; Every reaction breaks bonds and makes bonds. Which process dominates decides whether…. A cold pack feels cold because the reaction inside is taking energy from your hand.

Who is the Energy in Reactions poster for?

Energy in Reactions is filed under 10th Grade (ages 15–16), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting science, and to the parent or teacher answering the question at the kitchen table.

When should you use the Energy in Reactions poster?

Breaking bonds absorbs energy. Making bonds releases it. The balance decides the direction. A wall chart earns its place by being glanceable from where the work is happening, so Energy in Reactions belongs on the wall where that science work actually happens, within glancing distance, rather than filed away.

What other posters go with Energy in Reactions?

Acids and Bases, Balancing Equations and Covalent Bonding sit alongside Energy in Reactions in the 10th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Acids and BasesBalancing EquationsCovalent Bonding

Is the Energy in Reactions poster free to download and print?

Yes. Energy in Reactions downloads as a free PDF with no account, no email and no watermark, like everything else in the 10th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Energy in Reactions poster print at?

Energy in Reactions is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Energy in Reactions loses nothing.Printing guide
